Definitions

  • the invention relates to a device for covering manholes or the like in the area of roads, with a tube which is slidably guided in a cover ring, which is fixedly attached to a shaft, and with a retaining ring attached to the tube for receiving a manhole cover, which is in the area the street surface is arranged.
  • a manhole cover is known from WO 82/04276, in which a frame part for a manhole cover is anchored in an upper layer of the road substructure by a dome-shaped holding section. On its underside, the frame part is provided with a downwardly projecting sleeve which surrounds a shaft pipe with play, so that an axial movement is possible to a certain extent. Changes in the ground caused by frost can be partially compensated in this way. However, if there are shifts parallel to the road surface or an inclination in addition to the changes in height, this cannot be compensated. In addition, the tube sliding in the sleeve may jam, so that the intended function cannot be performed.
  • a relevant device is known from the applicant's WO 99/53148, which makes it possible to adapt the shaft system to the respective conditions, in particular to the distance of the, by inserting intermediate rings to ensure the actual shaft to the road surface.
  • the individual rings are attached to one another with limited mobility, so that certain movements of the road surface due to frost settling or the like can be absorbed without damaging the components. It is also possible with this system to tilt the upper ring, as is necessary, for example, on inclined roads. Although this system fulfills all requirements in an excellent way, it should be noted that it consists of a large number of components and is therefore complex.
  • AT 403 492 B shows a manhole cover in which a cover frame is fastened with a pipe that is sealingly connected to the actual sewer structure.
  • a change in the inclination of the frame occurs due to changes in the road surface, be it due to work, be it through frost or the like, this is inevitably associated with a displacement of the frame in the direction of the road surface in the known shaft closure, but this is due to Fixed anchoring of the frame in the road superstructure is not permitted. Accordingly, problems or device breakage occur in such cases.
  • the object of the present invention is to avoid these disadvantages and to provide a simplified solution which basically gives the same functionality.
  • the system should be easy to manufacture and easy to use.
  • the retaining ring is attached to the tube in a detachable and limitedly movable manner.
  • the cover ring is firmly connected to the uppermost manhole ring.
  • the fixed connection can be made per se by screwing or the like, but in many cases it is entirely sufficient to place the cover ring only on the upper end face of the manhole ring, since sufficient pressure is generated after backfilling through the ground or the road base, which ensures a secure hold.
  • the pipe is pushed into the cover ring and thus into the interior of the shaft as far as is necessary.
  • the retaining ring can be tilted relative to the tube, the axes of the retaining ring and tube enclosing a small angle in the tilted position.
  • the angle between the axis of the retaining ring and the axis of the tube is a maximum of 20 °, preferably a maximum of 10 °. In this way, the inclinations or the like that occur in practice are reliably recorded.
  • the manhole cover can be reliably and long-term kept flush with the road surface if the retaining ring has a bearing surface which is intended to rest on a road substructure.
  • the retaining ring it is possible for the retaining ring to have anchoring elements for fixing in the road structure.
  • a particularly advantageous design variant of the invention provides that the tube has a plurality of anchors which can be attached to the retaining ring with play. It is advantageous if the anchor is to be attached or detached from the pipe by turning the retaining ring. The attachment takes place in the manner of a modified bayonet lock.
  • the cover ring has a sealing surface on its inner diameter which interacts with the outer circumference of the tube.
  • the laying of the device according to the invention is particularly facilitated in that the cover ring is attached to the pipe with an interference fit.
  • the cover ring is attached to the pipe before installation and is held captive by the pipe due to the press fit.
  • the pipe end is inserted into the top manhole ring until the cover ring lies on the top face of the top manhole ring.
  • the cover ring holds the pipe and prevents it from slipping further into the shaft ring.
  • the area around the pipe can be filled with road substructure material, thereby securing the cover ring to the shaft and providing axial guidance of the pipe.
  • the tube can be pushed further down by applying appropriate pressure forces if the holding forces of the cover ring and the surrounding sub-material are overcome.
  • the cover ring and the tube are preferably made of plastic, a separate seal to the tube not being required by selecting the corresponding plastic material of the cover ring, which considerably reduces the production costs.
  • FIG. 1 is a side view of a device according to the invention in the installed state
  • FIG. 3 shows a section corresponding to FIG. 2 in the tilted position of the retaining ring
  • Fig. 7 is a side view of the tube
  • Fig. 8 is a side view of the tube of another embodiment of the invention.
  • FIG. 1 shows a shaft 1 on which the device according to the invention is placed, which consists of a cover ring 2, a tube 3 and a retaining ring 4.
  • the cover ring 2 is placed on the upper end face of the shaft 1 and fixed by the road substructure material indicated with 5.
  • the retaining ring 4 is flush with the road surface 6 and receives a manhole cover, not shown.
  • FIG. 2 shows a state immediately after the installation of the device and before the backfilling with road foundation material.
  • the pipe 3 is opened held by the cover ring 2 due to the friction, and the retaining ring 4 sits on the tube 3 and is arranged in the lowest position.
  • 3 shows a possible inclination of the retaining ring 4 relative to the pipe 3, as a result of which inclinations of the road surface 6 can be compensated for.
  • the retaining ring 4 can also be raised as a whole with respect to the tube 3 in order to have scope in the production of the road surface 6.
  • the axis 4a of the retaining ring 4 has an angle ⁇ of approximately 3 ° with respect to the axis 3a of the tube 3.
  • FIG. 4 shows the retaining ring 4, which has a flange 7, on the lower side of which a support surface 8 is formed. From the flange 7 a ring 9 protrudes upwards, which is provided for centering the lid or a lid frame, not shown, and is supported by ribs 10 to the outside. At regular circumferential intervals 4 holding baskets 11 are provided on the holding ring and each have an elongated hole 12 for holding the tube 3. From FIG. 7 it can be seen that anchors in the form of retaining bolts 13 are attached to the tube 3 and are designed to engage in the elongated holes 12. In this way, the retaining ring 4 can be connected to the tube 3, with limited mobility being ensured. In the embodiment of FIG. 8, hooks 13a are provided instead of the retaining bolts 13, which engage in recesses in the retaining ring 4, not shown. In this way it can be avoided that the receiving baskets 11 are a hindrance during installation.
  • the cover ring 2 and the tube 3 are made of plastic, the fit at the contact point 14 being designed as a press fit, that is to say that the tube 3 can only be displaced relative to the cover ring 2 using a force which exceeds the total weight of the device , This ensures that the device is inherently stable during installation.
  • the retaining ring 4 has a collar 15 projecting downward from the support surface 8, which surrounds the tube 3 on the outside with little play, so that the tube 3 is centered and guided.
  • the present invention is excellently suited to providing a covering for manholes in which difficult conditions are present, such as is the case with heavily used roads, rapidly changing temperatures or the like.
  • difficult conditions such as is the case with heavily used roads, rapidly changing temperatures or the like.
  • the invention is not only suitable for use in the area of roads, but that other applications are also possible.
