Description

The invention relates to a trench unit, which is formed substantially as a hollow body and a base wall and a plurality of connecting walls which protrude from the base wall, wherein at least a part of these walls is designed to be permeable to liquid, and wherein these walls define at least one fluid receiving volume.

For the purpose of disposing of surface water, such as rainwater, especially in larger towns and cities usually the sewer system is used. However, this type of disposal is relatively expensive, since the cross sections of the sewer lines must be dimensioned such that, for example, the resulting in a downpour rainwater can be removed easily. In addition, this type of disposal of rainwater is unecological because the rainwater can not seep into the soil on which it has fallen. It was therefore already sought in the past ways to be able to initiate rainwater into the ground even if its surface is sealed by buildings, roads, paths and the like.

For example, EP-A-0 934 737 has proposed a trench assembly composed of a plurality of generic trench units. This trench assembly forms an underground water basin, which is connected upstream with at least one gully, so that it the rainwater collected on the sealed surface through the at least one gully and optionally on it subsequent feed system can be supplied. The bottom surface of the trench assembly is liquid-permeable, so that the rainwater supplied to it can seep into the underlying soil. On the drain side, the trench assembly can be connected to the sewage system in order to be able to prevent backflow to the surface when the accumulated rainwater quantity exceeds the absorption capacity of the soil and the trench arrangement.

A disadvantage of the known trench arrangement, however, is the fact that the rainwater introduced into it carries all kinds of debris, in particular dirt, dust, earth particles and leaves, carelessly discarded waste, for example cigarette butts, and the like.
Also, the presence of screen baskets in the gullies as well as the provision of gullies in the feed system can not prevent a significant portion of this garbage from getting into and contaminating the trench assembly, especially the seepage openings at the bottom of the trench assembly. Since there is no possibility for cleaning in the known trench arrangement, the known trench arrangement is gradually rendered inoperative.

In addition, reference is made to the infiltration system Juncus Duobox REWATEC. This is formed by a package of perforated plastic corrugated sheets, which is penetrated approximately at half the height of a perforated plastic pipe. Due to its design as a corrugated iron core, this infiltration system has a high stability in terms of passing on or driving on. However, this design hampers the even distribution of the supplied water over the entire seepage soil area. At least the supplied rainwater in the Sickerbox can not spread as quickly as is required in a downpour. In addition, the perforations in the drainage pipe and the corrugated sheets increase relatively quickly if no suitable filter is connected upstream of the infiltration system.

Although a cleaning lance can basically be introduced into the drainage pipe. However, the water ejected from this cleaning lance can at best clean the perforations of the drainage pipe. On a cleaning of the entire Sickerbox, but especially the infiltration effective bottom surface, is due to the corrugated iron execution in any case.

For the sake of completeness, reference should be made to the following documents for the further state of the art: DE-U-299 23 191, DE-U-200 02 627, DE-A-38 42 012, DE-A-197 05 824 and DE- A-198 24 456.

In contrast, it is an object of the present invention, a trench unit of the type mentioned in such a way that it can be easily cleaned in the laid in the ground state.

This object is achieved by a trench unit of the type mentioned above, which further comprises at least one inspection channel which extends substantially parallel to the base wall, extending over a large part of the height of the trench unit, and is open at its two longitudinal ends. The term "inspection" encompasses both the investigation and the cleaning of the trench unit. Thus, an inspection device, for example a camera dolly, and / or a cleaning device, for example a high-pressure lance discharging water or a rinsing vehicle, can be introduced from time to time into the trench unit by the inspection channel provided according to the invention. The open at both longitudinal ends training the inspection channel ensures that when assembling; a plurality of such Rigoleneinheiten to a trench assembly, the cleaning device can move from Rigoleneinheit to Rigoleneinheit, so as to clean the entire trench assembly. In order to work with larger and therefore more powerful cleaning device, the inspection channel extends over a large part of the height of the Drainage trench. Preferably, the inspection channel may extend over substantially the entire height of the trench unit.

Of course, in "normal" operation, i. when liquid, for example, as a result of rain, and the inspection channel for receiving liquid.

If the inspection channel is delimited laterally by at least two connecting walls, this can ensure that the inspection device moves in a targeted manner along a predetermined path in the trench arrangement. The two connecting walls take up relatively little volume, so that the liquid receiving volume of the trench unit according to the invention essentially corresponds to that of a single-chamber trench unit. In particular, the connection walls bounding the inspection channel practically do not hinder the uniform distribution of the liquid over the entire base area of the hollow body forming the trench unit. In addition, they increase the stability of the trench unit so that it is easily accessible and passable.

In order to be able to reach substantially the entire bottom surface of the trench unit for cleaning purposes from the inspection channel, it is proposed that a base surface of the inspection channel of an envelope be arranged adjacent to the base wall. In order to be able to ensure the stability of the trench unit, the base surface of the inspection channel may have a predetermined distance from the envelope, within which, for example, stabilizing or stiffening ribs may be provided. Furthermore, the base surface may be formed by a portion of the step-shaped base wall.

In order to be able to use even on wheels moving inspection device, it is proposed in a further development of the invention that at least a part of the base surface of the inspection channel is formed substantially over the entire surface, i. if necessary, it is perforated by a small proportion of the total area of this base area, preferably slot-shaped openings. In this case, the preferably slot-shaped openings ensure that the water stored in the trench unit can also seep through the base surface of the inspection channel. If the longitudinal direction of these slots is substantially orthogonal to the longitudinal extent of the inspection channel, they may assist the traction of the wheel-based inspection device as it moves along the inspection channel.

To achieve the most uniform possible cleanability of the trench unit, the inspection channel may preferably be arranged approximately in the middle of the transverse extension of the trench unit.

In order to facilitate the accessibility of the inspection channel, at least one of the free ends of the inspection channel can be designed for connection to a pipeline or to a pipeline adapter. In this case, the pipe to be connected to the inspection channel may also be only a short piece of pipe for connecting the trench unit to a shaft running vertically in the ground. This shaft can be, for example, an inspection shaft through which inspection and cleaning equipment can be introduced into the inspection channel. If the trench arrangement comprises a plurality of layers of trench units arranged one above the other, then at least the lowermost layer of trench units should be connected to the inspection chute, since the surface of the trench arrangement requiring seepage requires special cleaning. At the bottom of the inspection shaft can also be provided a sinking volume, in which at least a portion of the rainwater entrained debris can settle before the rainwater in the Trench arrangement is initiated. In this sinking volume but can also be flushed out by the cleaning device from the bottom of the trench assembly messed up and debris. The sink volume of the inspection well can then be cleaned in a conventional manner. Additionally or alternatively, however, the shaft can also be an overflow shaft, which in turn is in turn connected to the sewer system. Therefore, the uppermost layer of trench units is preferably connected to this overflow shaft so that liquid from the trench assembly only flows into the overflow shaft when the storage volume of the trench assembly is exhausted.

At least one of the free ends of the inspection channel may further comprise an insertion slope facilitating the passage of examination and / or cleaning equipment, for example wheel-supported equipment, from trench unit to trench unit. In particular, this instruction slope allows a higher tolerance when laying the trench units.

In a development of the invention, it is further proposed that the trench unit comprises two base walls which run essentially parallel to one another. In this case, one of the base walls form a bottom wall of the trench unit, while the respective other base wall forms the top wall thereof.

Alternatively, the trench unit may be formed as an open-topped basket. When superimposing a plurality of trench units in a trench arrangement, the base or bottom wall of a trench unit arranged above a considered trench unit simultaneously forms the top wall of the trench unit under consideration. The top wall of the trench units of the uppermost layer of trench units may, for example, be formed by one or more cover plates. However, it is also conceivable, the trench unit as after to form the bottom open basket. When superimposing a plurality of trench units in a trench arrangement, the base or top wall of a trench unit arranged below a considered trench unit simultaneously forms the bottom wall of the trench unit under consideration. The bottom wall of the lowermost layer of trench units may for example be formed by one or more base plate (s).

To ensure good permeability of the walls of the liquid rigging unit, i. For rainwater as well as for pressurized cleaning water to ensure, is proposed in the invention that the bottom wall and / or top wall and / or at least one of the connecting walls is at least partially formed as a grid structure with the structure stabilizing struts and of these Struts bounded openings, these openings allow the escape or / and entry of liquid. The openings may occupy as 50%, preferably more than 75% of the total area of the respective walls or the respective wall sections.

In order to be able to further improve the accessibility or the navigability of the trench unit, it is proposed that at least one support column connecting the bottom wall to the top wall is provided, which preferably extends orthogonally between these walls.

A structurally simple construction of the trench unit results when it is formed by two trench sub-units, each comprising a main wall and a plurality of this main wall, preferably substantially orthogonal, projecting side walls, wherein the two trench sub-units are composed such that the main wall the one Rigolenuntereinheit the bottom wall of the Rigoleneinheit, the main wall of the other Rigolenuntereinheit the top wall of the rigging unit and each other kopprespondierende side walls of the two trench sub-units in pairs each form a connecting wall of the trench unit. This assembly of the trench unit from two trench sub-units, in particular when the trench unit is made of plastic by injection molding, has the advantage that with identical design of the trench sub-units only a single tool for injection molding the trench sub-units is required. For the injection molding of advantage is in particular the formation of the trench sub-units as upwardly open basket.

For operationally fixed connection of the two trench sub-units, at least one separate connecting element can be used, for example clamp elements, latching elements, clamping elements or the like. However, it is also possible to arrange an adapter plate or an adapter frame between the two trench sub-units, which in addition to the connection of the two trench sub-units can also serve to give the trench unit a desired height.

When at least one support pillar is formed by two semi-pillars which protrude from the main wall of a respective trench sub-unit, preferably substantially orthogonally, the free ends of at least a part of these pillars may each be interconnected by a separate connector. For example, receptacles may be formed in the free ends of the half-support columns of a half-support column pair, into which a latching or clamping element can be inserted. In principle, however, the use of clamping sleeves is conceivable, which inverts over the free ends of the half-support columns.

In order to store the trench unit as space-saving as possible, it is proposed in a further development of the invention that it or at least one of the trench units forming it be foldable or foldable, preferably such that in the collapsed state it has substantially no liquid receiving volume , For this purpose, at least one connecting wall can be pivotably arranged with one of its edges on an adjacent wall of the trench unit, while it can be fastened, preferably clamped, to at least one further edge on a further wall of the trench unit. In the collapsible training can also be provided that at least one connecting wall has at least two pivotally hinged parts, at least one of these parts is arranged with a line connecting the parts substantially parallel edge in turn pivotally mounted on an associated wall of the trench unit.

In order to be able to ensure a stable connection of the trench units when stacking or / and juxtaposing or / and stacking a plurality of trench units to form a trench arrangement, it is proposed that the trench unit is designed such that it can be connected to an adjacent trench unit by positive locking or by attachment Separate connecting elements in at least one direction orthogonal to the succession direction is substantially immovably connected.

In Fig. 7, a trench unit according to the invention is generally designated 100. This trench unit 100 is composed of two trench sub-units 102, of which, for reasons of clarity of illustration, only the lower one is explicitly shown, while the upper one is only indicated by dashes. The two trench sub-units 102 are formed identically, in accordance with FIG. 7 as an upwardly open "basket". To form the trench unit 100, the upper trench sub-unit 102 is turned upside down, so that the two trench sub-units 102 abut one another with their "basket openings" facing each other and thus together form a closed box structure.

The trench sub-unit 102 shown in FIG. 7 comprises a main wall 104 and outer side walls 106 and 108. The side walls 108 are formed as a continuous lattice structure, while the side walls 106 each comprise two lattice-structure sections 106a which are separated from one another by an opening section 106b. The bottom wall 104 comprises two coarse-meshed Lattice structure sections 104a, which are separated from each other by a surface portion 104b. Only a small surface portion of the surface 104b is occupied by slots 104c extending transversely to the longitudinal direction L of this surface 104b. The position of the surface 104b between the two grid structure sections 104a corresponds to the position of the opening sections 106b between the associated grid structure sections 106a of the side walls 106.

In the area of the side edges of the surface 104b, further side walls 110 designed as a grid structure protrude from the main wall 104.

After joining the two trench sub-units 102 to the trench unit 100, the main wall 104 of the lower trench sub-unit 102 forms the bottom wall 120 of the trench unit 100, while the main wall 104 of the upper trench sub-unit 102 forms the top wall 122 of the trench unit 100. Corresponding side walls 106 and 108 or 110 of the trench sub-units 102 form connecting walls 124 of the trench unit 100. Finally, the main wall sections 104b and the adjoining side walls 110 of the upper and lower trench sub-units 102 together define an inspection channel 130 which guides the trench unit 100 in the direction L. completely penetrated and open at its two longitudinal ends 130a. At this time, these open ends 130a are formed by the opening portions 106b of the side walls 106 of the two trench sub-units 102.

In this way, the trench unit 100 shown in FIGS. 7 and 8 has a three-chamber structure, the three chambers corresponding to the two sections 104a and the one section 104b of the main wall 104. Keep in mind that in the normal cache and Seepage operation of the rigging unit 100 and the inspection channel 130 for receiving rainwater is used.

On the other hand, in the inspection mode, inspection unit 130 may feed inspection unit 130 into trench unit 100, e.g. a device for examining the condition of the trench unit 100 or else a device for cleaning the trench unit 100 can be introduced. In the case of using wheel-mounted inspection equipment, the transverse slots 104c in the bottom surface 104b, in addition to allowing fluid to pass through this bottom surface 104b, have the task of improving the traction of the wheels of the inspection device on the bottom surface 104b. In the area of the open ends 130a of the inspection channel 130, the bottom surface 104b also has an insertion slope 104d which is intended to facilitate the transfer of the inspection device from the inspection channel 130 of a considered trench unit 100 into the inspection channel 130 of the next trench unit 100 if these two trench units 100 are not are arranged precisely at the same height.

For examining the condition of the trench unit 100, for example, wheel-supported camera carriages can be used. As a cleaning device, for example, lances can be used, the water eject under high pressure obliquely backwards and refer to their recoil from this recoil.

In order that the ejected water can also reach the entire liquid receiving volume of the trench unit 100, the lattice structure walls or wall sections 104a, 106a, 108 and 110 are formed as open lattice structures. That is, the area occupied by the openings 112 is larger, preferably considerably larger, than the area occupied by the webs 114 bounding these openings 112 (see FIG. Not only in the height direction H, depth direction T and transverse direction Q extending webs 114 are provided, but also obliquely to at least two of these three spatial directions extending webs. As a result, the rigging unit 100 is given sufficient stability to be able to commit or even drive on.

In order to increase the stability of the trench unit 100, stabilizing ribs 116 are also provided below the bottom surface 104b of the inspection channel 130 or / and in the interior of the trench unit 100. In order to be able to provide these stabilizing ribs in the area of the bottom surface 104b of the inspection channel 130, this bottom surface 104 has a predetermined distance d from an envelope U of the bottom wall 104 or 120, which in practice may amount to a few centimeters.

Finally, the trench subunit 102 further comprises a plurality of semi-pillar columns 118 which project substantially orthogonally from the bottom surface 104 and form support pillars 119 in cooperation with corresponding pillar columns 118 of the respective trench sub-unit 102, which forces from the top wall 122 of the trench unit 100 to the bottom wall 120 thereof hand off.

Recesses 118b are formed in the end surfaces 118a of the semi-supporting columns 118, into which clamping bolts 140 can be inserted as separate connecting elements of the semi-supporting columns 118. The clamping effect can be achieved in different ways. For example, the clamping bolts 140 may be slightly oversized compared to the recesses 118b.

In Fig. 10 is a collapsible rigging unit 200, more specifically a rig member subunit 202 of this trench unit shown, wherein Fig. 10a shows the unfolded state or ready-to-lay state or operating state and Fig. 10b shows the folded state or storage condition.

On the main wall 204, on the one hand, the side walls 206 are articulated about an axis B and, on the other hand, the side walls 208 are pivoted about an axis A. Namely, the linkage is based on the main wall 204 at different heights to stack the side walls 206 and 208 in the folded state of FIG. 10b to save space on each other.

The invention relates to a trench arrangement with one or more trench components which can be arranged to form a trench basin, wherein the trench components are designed as water absorption bodies which can be connected to one another, according to patent claim 1.

For the purpose of surface and rainwater disposal, especially in urban areas, the municipal sewers are often used. Such organized rainwater disposal is relatively expensive as well as non-ecological, and consequently, ways have been sought of introducing rainwater and surface water into the soil, even when the soil is being built, paved or otherwise sealed.

Thus, for example, from EP 0 286 662 B1 a type of underground water basin is known, which is intended for collecting rainwater and for the controlled introduction of rainwater into the soil. Here, individual cells are arranged side by side on a gravel bed, so that the individual cells, fed via a supply line ending at the basin, can buffer water before the water is then introduced into the ground. Here, on the one hand, the function of a storage tank for rainwater is to be fulfilled in this way on an area with a comparatively small extent and, on the other hand, the amount of water to be introduced into the surrounding soil from the storage basin can be introduced by it. According to further embodiments, this trench basin is also connected to a sewage network, in the event that too much water is generated, which can not be easily discharged or stored in the ground. In this type of trench assembly, however, there is the problem that the just introduced in a massive rainwater seepage dirt, dust, and soil particles and the like. Lead to the areas that determines the transport and the discharge of water into the ground are, polluted and added. Such a trench assembly then has to be dug up again and cleaned, since there is hardly any possibility of cleaning the gravel bed any nonwoven foils or the individual trench components of this known trench arrangement.

Another trench arrangement is known from EP 0 770 735 A1, in which rainwater is also introduced into a trench assembly composed of trench components. This trench assembly is also located underground and walkable, as in accordance with the invention. Here are the individual Rigolenbauteile in the form of tubes, honeycombs or dg1. provided, and are connected to each other through small holes, so that rain water, which is introduced into the inlet of the trench assembly closest lying trench component, flows through the holes in adjacent Rigolenbauteile. Again, there is of course the danger that the connecting holes are added by unavoidable dirt and suspended solids in the rainwater and the effectiveness of this arrangement can after a short time after.

A disadvantage of the known Rigolenanordnungen and their Rigolenbauteilen alike, that on the one hand usually a gravel bed is required, the cost is expensive and time-consuming and also the Rigolenbauteile are extremely bulky and space consuming. For storage and transport, these trench components require a large amount of space, which can be particularly problematic on the construction site, where there is a lack of space regularly. Also, the trench components in the usual form are constantly exposed to the risk of damage, since the trench components are usually made of plastic and, surrounded by soil in the ground although very stable, but against impacts, such as during transport and storage can occur on the construction site, quite sensitive.

It is therefore the object according to the present invention to propose a trench arrangement or a trench component which provides the abovementioned disadvantages in the prior art as far as possible a remedy. In particular, a trench assembly to be created, which can be maintained in their function over a long period of time without the trench assembly must be dug up for cleaning purposes. Furthermore, a suitable to build such a trench assembly Rigolenbauteil to be proposed, in addition to a rigole component of this type is to be proposed, which requires little storage and transport space.

According to the invention, the above-mentioned objects are achieved by a trench assembly with the features listed in claim 1. Furthermore, by the features of the remaining independent claims 10 and 16, trench components are proposed, which also contribute to the solution of said objects.

According to the invention, a trench assembly is composed of one or more components, the rainwater or surface water being supplied via at least one water conduit substantially continuous through the trench member (s), the water conduit being provided with openings to direct the water into the or To initiate trench components. The continuous water pipe, which should be as little or not interrupted in the area of the trench assembly, makes it possible to remove dirt and suspended solids, which would otherwise inevitably accumulate in the trench arrangement and curb their effectiveness, from time to time to remove permanently, so that too after a long service life by relatively inexpensive measures, the effec-tivity of the trench assembly according to the invention can be maintained.

In this case, a feed shaft can be provided in front of the trench basin or the trench arrangement according to the invention, via which the water to be temporarily stored and to be infiltrated can be introduced into the trench arrangement according to the invention. This inlet shaft can then be used simultaneously as a maintenance shaft, in which case, for example, at a connecting pipe, via which the shaft is connected to the water line passing through the trench assembly, a connection section can be provided, for example, a high-pressure line or the like. For cleaning purposes to be able to connect here. Of course, beyond the trench arrangement also an overflow shaft can be provided, which can equally serve as a maintenance shaft and can be equipped accordingly, as has already been discussed in connection with the maintenance or feed shaft.

The water-absorbing bodies, each of which may be contained in a trench member, but a trench member may also directly correspond to a water-absorbing body may be provided in the form of vertical tubes, honeycomb vertical tubes or the like. Since these water absorption bodies or trench components are connected to one another via the, if possible, substantially continuous water pipe and their openings, it is not necessary to connect these trench components or water absorption bodies again laterally separately via openings. On the other hand, corresponding openings can be provided in order to further improve the fluid exchange between these trench components or water absorption bodies.

It is also advantageous to equip a trench component, for example, with supports, columns or other stabilizing elements, which need not necessarily represent hollow body.

The trench assembly or the Rigolenbauteile should at least have their openings at the vertical lower end or be open so that the water that is introduced into the trench assembly can be introduced from there into the ground. Here, nonwovens or the like. Be provided to prevent ingress of soil into the trench assembly according to the invention.

It should be noted that the trench assembly according to the invention does not need a gravel bed on which it rests to fluidly connect the trench assembly to the surrounding soil. On the other hand, it may well be appropriate for certain soil conditions to deposit such a gravel bed before the trench assembly according to the invention is installed. The trench assembly according to the invention is designed so stable that it is walkable or passable after installation.

The individual water-absorbing body or trench components can advantageously be equipped with respective water-line sections, which can then be connected to one another via connection regions, in order to produce a water pipe that is as continuous as possible in this way. On the other hand, it is also possible to provide the trench components or the water absorption body only with openings, so that after the arrangement of the trench components to a trench assembly according to the invention via the openings a continuous, provided with Auslassperforationen water pipe can be passed.

Through the Rigolenbauteil or by the trench assembly can also pass through several water pipes with perforations. These can be laid at different heights to ensure both the best possible irrigation and drainage as well as the best possible ventilation. The or the pipes or water pipes can be laid with a gradient.

Also, the water pipes or pipes can be provided in the longitudinal direction with changing cross sections and / or diameters.

Furthermore, the water pipe (s) can be formed in certain peripheral areas with openings or perforations, while other areas are dense. Here, for example, it is advisable to use the lower regions, that is, the sole of the pipeline substantially dense, i. about imperforate form, and to provide upper areas with openings or perforations.

Also, the perforations or openings may be formed differently over the circumference, for example in the lower cross-sectional area with a small opening area and in the upper with a larger one. The openings or perforations in the water line (s) can be designed in such a way that they can contribute to the cleaning of the trench arrangement according to the invention. For example, the openings may be formed such that, for example, at certain flow velocities, a suction effect is created, via which contaminants can be removed.

In order to stabilize the trench assembly according to the invention, the water-absorbing body or trench components should be equipped with mechanical connection means, for example interlocking engagement elements or the like., In order to mechanically stabilize the body of the trench assembly against earth movements. It is also possible to superimpose several layers of corresponding trench components or water absorption bodies in order to increase in this way the receiving volume of the trench assembly with features according to the invention. For this purpose, the Rigolenbauteile or receiving body may be open or closed at its upper and / or lower end portions, depending on whether they are to be connected to other layers or represent an end position. If an inventive water absorption body or an inventive rigging component represent an upper end portion, it may be completely closed or else be provided with outlet openings, which is determined by the circumstances that brings the surrounding soil for presentation. If the relevant location of the trench components is the lowest position, it should be provided with bottom sections which have openings, perforations, fleeces or the like in order to be able to discharge water into the ground.

The present invention is directed not only to the trench assembly discussed above and the trench member described in connection with this trench assembly, but additionally to a trench member having at least two pivotable side walls for collapsing the component or water receiving body. Such a collapsed Rigolenbauteil can be easily stored, since it only has a fraction of its existing in the mounting position size. Furthermore, it is much easier to transport. Thus, a conventional range can be built with correspondingly collapsed Rigolenbauteilen to a trench assembly having ten or twenty times the size of the stored Rigolenbauteile. This is a huge advantage, since a production in supply so far by the large storage area, the corresponding components of known type need, was possible only to a very limited extent.

Of course, at least three or all side walls of a corresponding Rigolenbauteils can be designed to be movable. It is also possible to have at least two side walls form foldable, so that they can be folded into each other and thereby let entire Rigolenbauteile coincide in itself.

A bottom and / or top plate may be combined with the built-up components, i. the side walls, be provided connectable. This bottom and / or top plate may be insertable into a frame or the like which results through the end portions of the unfolded sidewalls to impart mechanical stability to the assembly.

In a trench component designed in accordance with this aspect of the invention, a water pipe or a water pipe section may be introduced in which pipe insertion openings are provided. It is also possible to provide a compressible and / or collapsible water pipe, for example in the form of a corrugated pipe or a film tube, which can be formed correspondingly compressible.

As sections between the movable side walls or floor and / or ceiling walls, any sections may be provided, for example, film hinges, which can be particularly easily and easily produced. On the other hand, pivot joints, slotted guides and the like. Can be used. Here the expert many different means are known, which he can bring to use. A conclusive enumeration is therefore not necessary. According to a further advantageous embodiment, a trench component can be divided into at least two components. These components can each be unfoldable and connected together to form a trench component. In such an embodiment, it is possible to provide the as possible continuous water supply in one of the components according to the invention, so that when side walls are folded, the water pipe is not a hindrance, since the wings of the side walls are short enough not to connect to the water pipe to collide.

The storage capacity of a trench assembly according to the invention for water is advantageously 90 to 95%. Due to the training of plastic, it is possible, about 95% of the volume of the trench assembly according to the invention with Rigolenbauteilen according to the To use the invention for water storage. Of course, trench assemblies constructed in accordance with the invention may also have lower storage capabilities.

The trench assembly according to the invention is not only suitable for storing and discharging rainwater into the ground, but is equally suitable, for example, to serve as a heat storage for hot water, such use as a tank, of course, requires an outwardly sealing training. Furthermore, the invention Rigolenfüllkörper can also be used as a ground tank for oil, chemicals or other things, since it can be relatively easily cleaned. Of course, in such an application, the trench members, as indicated above, are not provided with openings through which chemicals, oil or the like could be introduced into the soil. If the trench assembly according to the invention is used as a storage, it is recommended that the arrangement of the intended water pipe or liquid line at the lower end of the trench assembly and thus also at the lower end of the used Rigolenbauteile to the entire stored liquid or the entire stored water, oil or the like to pay off again.

Although it is advisable to produce the objects according to the invention from plastic, it is readily possible to use metals or mineral or ceramic or organic materials to meet certain requirements. Thus, for example, aluminum could yield particularly stable trench components and thus a particularly stable trench filling body. If oil or chemicals are to be stored, materials other than plastic may prove useful in order to meet special requirements of special liquids.

FIG. 1 shows a trench assembly with features according to the invention, which is generally designated by the reference numeral 10. The trench assembly 10 is installed in a soil 8, which may consist partly of compacted material and partly of gravel. According to the invention, a gravel bed is not necessarily required, but may be useful in the discharge of rainwater into the soil. However, the soil above the trench assembly 10 may be made up of normal soil.

A covering 6, for example, the asphalt surface of a parking lot can make the introduction of rainwater into the ground impossible, so that just in such a place the installation of the trench assembly 10 with features according to the invention is very useful. Covers 11a, 11b are used to cover flushing and inspection shafts 17, 24 mechanically stable. These covers, for example made of cast iron, can be removed, for example, for maintenance or cleaning purposes.

The flushing and inspection shaft 17 is used in the illustrated trench assembly 10 as a feed shaft and accordingly has an inlet 20. Rainwater can be introduced into the shaft 17 via the inlet 20 via a feed line (not shown here). The rainwater will then first fill up the lower portion 18 of the shaft 17 until it reaches a water conduit 16 through which the water can pass into the trench components 12, 12 'forming the central component of the trench component according to the invention.

The water pipe 12, 12 'has various openings through which the introduced water can be introduced into the trench components or in water receiving body, which the trench components form. At the end of the water pipe 16, which is often perforated, a further flushing and inspection shaft 24 is connected via a connecting portion 26, which can be used as a drainage shaft. That is, in the case of a Überzuloteotes the shaft 24 may be connected to a public sewer network over which excess water can be derived. In order to retain as much rainwater as possible, a throttling drain may be provided in the region 26, which retains, for example, depending on the drainage properties of the substrate more or less water in order to let it seep underground.

As a central component of the trench assembly according to the invention, the trench components are to be regarded as having one or more water receiving bodies. The water-absorbing body may be tubular, honeycomb-shaped in cross-section, rectangular in cross-section, round in cross-section or otherwise formed. They can also be connected to one another via additional openings, so that a liquid exchange can take place between adjacent trench components 12, 12 ', which does not necessarily have to take place via the perforated or perforated pipe or water pipe 16.

In Fig. 2, the trench assembly 10 is shown in another form of representation. In addition to recognize a supply line 9, which opens into the inlet opening 20 of FIG. The trench components 12, 12 'are not shown here in detail. By contrast, the dashed representation of the water pipe 16 now makes it easier to verify that this water pipe 16 is provided with more or less large openings or perforations, via which liquid and, in particular, rainwater can flow into the trench components 12, 12 '.

At the end of the trench assembly 10 according to FIG. 2, a discharge -31 is shown, via which an excessive water tank can flow into a shaft 32 of a public sewage system. From there, the rainwater or surface water can be disposed of via a sewer pipe 34.

From the foregoing discussions, the central role of the aqueduct 16 can be seen, both the discharge and distribution of rainwater or surface water serves. Also, the water, ie an excessive amount of water, can be disposed of over this same pipe 16. The ventilation of the entire trench assembly can be done via this water line 16. A very important aspect is that this water line 16 can also be used to define a sedimentation of solids from the water defined and, since the sedimentation is easily accessible to remove them by cleaning or maintenance. Also, via the central line 16, the state of the trench assembly 10 according to the invention can be tested.

3 shows a single trench component 12 with a water pipe 16 passing therethrough, which can be designed both as a smooth-walled pipe with an opening and as a corrugated pipe with openings. At the respective ends of the water pipe 16 connecting portions 16a, 16b, for example, sleeve-like formed sections and pipe sockets are provided to provide a connection to pipe sections 16 adjacent Rigolenbauteile available.

FIG. 4 shows a collapsible trench component 12 'which has foldable side walls 30. Foldable head walls 32 are also shown. In order to equip such collapsible, for example rectangular or cubic, trench components with collapsible or foldable walls, many different models are known to the person skilled in the art of the plastics industry. Thus, e.g. be referred to folding crates, which are known about for the transport of goods in motor vehicles. The same principles can also be used here, such as folding joints, sliding blocks that run in rails or scenes, etc. It is also possible to make individual side walls hinged, swivel or foldable, while other walls plugged stabilizing inserted or with the unfolded side walls screwed, riveted or glued.

Fig. 5 shows such an embodiment in which, as in folding boxes, two side walls are foldable in itself, so that this Rigolenbauteil with a handle collapsible and can be rebuilt with a handle. The individual components 30a, 30b of a foldable side wall can be completely minimized in their extent. The upper and lower side walls 34a, 34b in the illustration lie directly against the folded one in this way Side walls 30a, 30b at. The embodiment 12 "according to FIG. 5 is thus highly collapsible, easy to set up and, moreover, can be mechanically stabilized with any upper and / or lower cover plates possibly firmly inserted.

6 shows a further embodiment of a collapsible trench component 12 '' ', which consists of two components 12a, 12b, which are each open on one side and serve as counterparts for each other in the assembled state The two components 12a, 12b The side walls 30c, 30d are relatively short-legged, so they can be folded inwards without interfering with a water pipe 16 provided on one of the components 12b.

Of course, a large number of different trench assemblies having features according to the invention and different trench members having features according to the invention will be apparent to those skilled in the art having the benefit of the present disclosure, so that the foregoing embodiments are merely exemplary of embodiments of the present invention ,

The invention relates to a trench arrangement with a plurality of trench components, which can be arranged to form a trench basin, wherein the trench components are designed as connectable to each other water absorption body, wherein at least some of these water receiving body or Rigolenbauteile 12 by common water lines 16, via the adjacent water receiving body are connected to each other the continuous water pipes 16 have openings 19 through which water enters or leaves the water absorption body or the trench component 12.
