Definitions

  • the invention relates to a trench for temporarily storing liquid, in particular rainwater, wherein the surface of the trench volume is at least partially covered by a filter layer and comprises at least one primary infiltration surface and at least one secondary infiltration surface.
  • Such rigs are mainly used as infiltration systems for rainwater and gain in municipal drainage planning increasingly important.
  • the trenches must ensure permanent drainage.
  • a sealed area such as a street or a parking lot
  • a decades of functionality must be guaranteed, since redevelopment in these areas are particularly complex and costly.
  • a generic Rigole is for example from the DE 101 23 754 A1 known.
  • a primary infiltration surface is understood to mean a surface area of the surface of the trench volume through which, in the case of a newly installed trench, most of the rainwater seeps by gravity. In the case of a rectangular rig, this is the substantially horizontally extending, flat bottom surface of the trench. In addition, part of the rainwater but also on the side surfaces of the trench. These side surfaces therefore form secondary infiltration surfaces in the sense of the present application.
  • the surface area of the bottom surface plus a quarter of the surface area of the lateral surfaces of the trench is used as the infiltration-active total area of a rectangular rig.
  • the invention also relates to trenches with non-cuboid shape. These can also be distinguished from primary and secondary infiltration areas.
  • a primary infiltration surface is generally understood to mean a percolation surface through which the rainwater passes downwardly in a more gravitational manner, while it is forced laterally through a secondary infiltration surface.
  • the main purpose of the filter layer is to prevent the penetration of substances washed out of the surrounding soil into the trench.
  • these alluvial agents are not a problem because they are replaced by the next rain from the rainwater collected in the trench and exiting from the filter layer again.
  • JP 02013622 For example, a trench is known that has a filter layer.
  • a trench of the type mentioned in which at least on a part of the side facing away from the trench volume of the filter layer, a liquid-conducting layer is provided, which extends from at least a portion of a secondary infiltration surface to at least a portion of a primary infiltration surface ,
  • a liquid-conducting layer in the context of the present invention is generally understood a layer whose liquid conductivity is greater than the liquid conductivity of the soil surrounding the trench.
  • the liquid-conducting layer thus forms a kind of "bypass", which directs the liquid emerging through the secondary infiltration surfaces into the region of the primary infiltration surfaces, which is particularly seepage due to the action of gravity, outside the filter layer clogged by sedimentation.
  • a further filter layer is provided at least on a part of the side of the liquid-conducting layer facing away from the trench volume.
  • the filter layer and / or this further filter layer may be formed by a nonwoven layer.
  • the filter layer, the liquid-conducting layer and possibly the further filter layer are joined together to form a prefabricated drainage unit.
  • the liquid-conducting layer is designed to be flexible, for example composed of a tangle of plastic filaments or a plurality of superimposed layers of plastic filaments oriented in different main directions or the like
  • this drainage unit takes on the overall shape of a flexible mat, which in a simple manner can be wrapped around the corners and edges of the trench.
  • the flexibility of the liquid-conducting layer and the drainage unit formed with it is of great importance in order to remove the liquid from the area of the secondary infiltration areas, i. the side surfaces, substantially free from interference in the area of the primary infiltration areas, i. the ground surface to be able to conduct.
  • the drainage unit may be formed as an overall substantially rigid plate.
  • the liquid-conducting layer may be formed for example by a, preferably made of plastic, grid structure.
  • plates which are made of loose poured and glued together at the contact points balls, for example made of polystyrene. In these plates, the liquid can flow through the intermediate spaces between the balls.
  • plates for example of polystyrene, can be used, are formed in the liquid-conducting channels during manufacture or introduced later.
  • mineral drainage layers for example a gravel layer embedded between two filter layers.
  • the liquid-conducting layer provided according to the invention on the outside of the trench can be advantageously used not only with cuboidal trenches, but that the same advantages can be obtained without difficulty even with differently shaped trenches.
  • trenches are known in which the trench volume is formed by a simple gravel packing.
  • the invention can be used in trenches, which is composed of a plurality of trench elements, such as trench elements, as described in the Application DE 101 23 754 A1 are disclosed.
  • the trench volume comprises a plurality of trench sub-volumes whose surface is at least partially adjacent to one another.
  • the size of the surface area of the secondary infiltration surfaces can be increased for the same volume of trench. This particularly has a positive effect on the infiltration performance of the trench when the primary infiltration surfaces of this trench are substantially completely blocked as a result of sedimentation.
  • the infiltration capacity is limited essentially by the absorption capacity of the soil arranged under the primary infiltration surface, and the flow resistance of the liquid-conducting Layer is lower in each case than that of the soil, the common use of the same liquid-conducting layer by two Rigolenteilvolumina in practice is not the infiltration capacity of the trench limiting factor.
  • the filter layer of a prefabricated drainage unit in the region of adjoining surfaces of two partial volumes of rubbing the filter layer of a prefabricated drainage unit be the filter layer of one partial volume of the trench and the further filter layer of the prefabricated drainage unit the filter layer of the serves other rig part volume.
  • the filter layer and the further filter layer of the prefabricated drainage unit are identical.
  • a first prefabricated drainage unit is placed with its end face on a surface region of a second prefabricated drainage unit, from which the filter layer and / or the further filter layer has been at least partially removed. In this way, the liquid-conducting layers of the two prefabricated drainage units go directly into each other, so that no additional flow resistance is generated by the transition.
  • the first prefabricated drainage unit has its end face directly on the filter layer of the second prefabricated drainage unit set up without it being feared in this Aufsetz Scheme clogging of the filter layer of the second prefabricated drainage unit.
  • the flow resistance increases in the transition or Aufsetz Scheme.
  • each of these trench elements may form a separate Rigolenteilvolumen and be provided at least in the region of its bottom surface and its side surfaces with a filter layer and a liquid-conducting layer.
  • the trench element provided with the filter layer and the liquid-conducting layer as a prefabricated structural unit.
  • a trench according to the invention is generally designated 10. It is composed of a plurality of Rigolen hypolligenn 12 which in the soil 14 below a sealed surface 16, for example a Street, a parking lot or the like, are arranged.
  • the rainwater 32 descending onto the surface 16 is collected in gullies 18, pre-cleaned in pre-cleaning devices 20, for example a sludge bucket, and then introduced into the trench 10 via a feed line 22.
  • the trench is covered on its outer surface 10a with a filter layer 24, which may be formed for example of non-woven.
  • a liquid-conducting layer 26 is provided on the side facing away from the volume 10b of the trench 10 side of the filter layer 24, the surface facing away from the filter layer 24 is advantageously covered by a further filter layer 28.
  • the filter layer 24, the liquid-conducting layer 26 and the further filter layer 28 may be joined together to form a prefabricated drainage unit 30.
  • the trench 10 is a cuboidal trench whose surface 10a comprises a bottom surface 10c and side surfaces 10d.
  • the bottom surface 10c in this case forms a primary infiltration surface of the trench 10, as the rainwater 32 emanating from it from the trench can immediately seep into the soil 14 following gravity.
  • the side surfaces 10d form secondary infiltration surfaces, since the water 32 passing through them first has to run down along the side surface 10d of the trench 10 before it can seep into the soil 14.
  • the secondary infiltration surfaces 10d retain their permeability, because of their substantially vertical orientation, less sediment can accumulate on them. Therefore, the rainwater 32 may pass through the secondary infiltration surfaces 10c and the filter layer 24 and enter the liquid-conducting layer 26. This is in FIG Fig. 2 indicated by the flow arrows 36a.
  • the liquid-conducting layer 26 acts as a bypass for the primary infiltration surface 10 c blocked by the sediment 34 and directs the rainwater 32 on the outside of the filter layer 24 into the area of the primary infiltration surface 10 c. This is in Fig. 2 indicated by the flow arrow 36b.
  • the trench 10 according to the invention retains at least a large part of its initial infiltration performance, since the rainwater 32 will pass through the secondary infiltration surfaces 10d and the liquid-conducting Layer 26, which acts as a bypass around the sediment layer 34, reaches the area of the primary infiltration surface 10c, which is particularly seepage-effective due to the influence of gravity.
  • the trench 110 according to 3 and 4 differs from the trench 10 according to Fig. 1 and 2 merely in that the trench volume 110b is subdivided into a plurality of trench sub-volumes 110b1, 110b2, 110b3.
  • the trench sub-volumes 110b1, 110b2, 110b3 abut each other but are at least partially separated from each other at the adjoining surfaces by a prefabricated drainage unit 130 '.
  • the side surfaces 110d of the outer surface 110a of the trench 110 but also the contiguous portions of the surfaces 110d 'of the trench sub-volumes 110b1, 110b2, 110b3 also form secondary infiltrations of the trench 110.
  • the liquid-conducting layer 126 ' is assigned in each case to two of the trench part volumes 110b1, 110b2. Furthermore, the filter layer 124 'of the prefabricated drainage unit 130' forms the filter layer of the one drawer part volume 110b1, while the further filter layer 128 'of the prefabricated drainage unit 130' forms the filter layer of the respective other drab part volume 110b2.
  • the transition of the prefabricated drainage unit 130 ', which is arranged between two adjoining partial girder subvolumes 110b1, 110b2, to the prefabricated drainage unit 130, which is adjacent to the bottom surface of the trench 110, ie the primary infiltration surface 110c of this trench 110, can be realized by removing a strip of the filter layer 124 of the drainage unit 130 whose width is substantially equal to the thickness d of the drainage unit 130 '. corresponds, and this drainage unit 130 'up on the drainage unit 130 upright.
  • the connection of the two drainage units 130, 130 ' can be secured by fastening means, for example clips, adhesions and the like. In this way, a substantially flow-resistance-free transition from the liquid-conducting layer 126 'of the drainage unit 130' to the liquid-conducting layer 126 of the drainage unit 130 is achieved.
  • the infiltration path of the rainwater 132 out of the sump subvolumes 110b1 and 110b2 out through the filter layers 124 'and 128' into the liquid-conducting layer 126 'of the drainage unit 130' continues along the liquid-conducting layer 126 of the drainage unit 130 into the area through which Sediment layer 134 clogged primary infiltration surface 110c and finally through the further filter layer 128 of the drainage unit 130 into the soil 114 is in Fig. 4 represented by the arrows 136a, 136b and 136c.
