Definitions

  • the invention relates to a method for connecting street drains to a rain or sewer, and a device for draining water, in particular rain water, from road surfaces or the like, with a water drain and a drain from the road to a lower-lying rain or Wastewater canal or a wastewater pipe leading to the control shaft connected to it.
  • the sewage pipes which lead from the street drains arranged near the curb to a rain or sewage canal that is usually several meters below the street level, must be at least partially relocated in order to connect them to the adapt to new circumstances.
  • Earthenware pipes are often used, which have been used as sewage pipes for decades.
  • PVC pipes have also been used for some time, especially when the sewage pipes run over long distances and essentially in a straight line.
  • the object of the invention is to develop a method and a device of the type mentioned at the outset which ensure greater flexibility and in which the disadvantages mentioned above are avoided.
  • This object is achieved according to a first alternative according to the invention in that at least one flexible piece of hose is laid between the outlet opening of the street gully and an inlet opening of the rain or waste water channel or the control shaft connected to the rain or waste water channel.
  • the sewage pipe can be quickly and easily laid around obstacles and at least in the area of the hose section connection points and the associated disadvantages can be avoided.
  • a second alternative according to the invention provides that between the outlet opening of the street gully and the inlet opening of the rain or sewage channel or the control shaft arranged sewage pipe is laid in one piece regardless of a predetermined piping, this being made possible in particular by the fact that the sewage pipe is formed by a single uninterrupted hose section which is laid between the street drain and the rain or sewer canal or the control shaft.
  • the flexible hose is supplied by the meter, and that a piece of hose with the required length is cut off before connecting the street drain to the rain or sewer.
  • a further advantageous embodiment of the invention provides that a piece of hose is separated, the length of which is somewhat greater than the measured distance.
  • the radius of curvature of an elbow in the hose line is increased slightly where the dimensions of the construction pit allow it and where the slope is not inadmissibly reduced, or the hose is laid on a straight slope with one or two curves, so that this difference in length can be easily compensated.
  • the reduction in the gradient caused by the somewhat longer length of the tube piece for a given height difference between the outlet opening of the street gully and the inlet opening of the rain or sewage channel is mostly negligible, at least for larger distances or height differences.
  • a further advantageous embodiment of the invention provides that the piece of hose is connected at one end at its lower end to a connecting piece opening into the rain or sewage channel or into the control shaft and from there is guided to the outlet opening of the street gully, so that the piece of hose comes on every point has a specified minimum gradient.
  • a hose is expediently used in any case which cannot be easily bent or compressed, the risk of a narrowing of the cross-section can be further prevented by covering the hose piece during laying or by covering it with concrete. This can advantageously be done either by pouring as much concrete onto the piece of hose after laying that it absorbs at least the majority of the weight of the layers of earth above it.
  • a closed covering made of a thin, flexible material for example sackcloth or a stable plastic film, can be attached around the piece of tubing, the inside cross section of which is larger than the outside cross section of the piece of tubing, so that at the top end between the piece of tubing and the covering filled concrete fills the space between the circumferential surface of the hose piece and the covering and forms a concrete jacket after hardening.
  • a sewage pipe By embedding the piece of hose in concrete, a sewage pipe is produced that has a pressure resistance comparable to that of conventional sewage pipes made of glazed stoneware, but unlike these, does not have any connection points and, in addition, does not lead to rainwater escaping underground if it breaks, for example due to subsidence leads, because the break point is bridged and sealed by the hose arranged inside the concrete jacket.
  • the piece of hose is expediently connected to a connecting piece arranged at the outlet opening of the street gully.
  • the connection between the hose section and the connecting piece can be done both on the street drain as well as on the rain or sewer or on the inspection shaft by pushing the end of the hose piece over the connecting piece projecting outwards beyond a wall of the street drain or sewer and for example attaching it to the connection piece with a hose clamp.
  • Such a relatively inexpensive and relatively inexpensive solution is particularly suitable for attaching the hose piece to a connecting piece of the street gully, since with this solution there is no cross-sectional constriction in the direction of flow.
  • the lower end of the piece of hose can be inserted into a connecting flange or a coupling element, which is then connected to the rain or sewer channel with a corresponding flange or coupling element. is preferably releasably connected to the control shaft.
  • an annular space between the outside of the hose section and an inner wall of the connecting piece can preferably be filled with a hardening bituminous sealing compound.
  • Cross-sectional constrictions can also be avoided by a sleeve that encompasses both the hose piece and a connecting piece or a fitting piece.
  • the existing pipeline is essentially straight and has a sufficiently large pipe diameter, it can be advantageous that the lower Push the end of the hose section inside the pipeline into the vicinity of its confluence with the rain or sewage canal or into the control shaft, thereby simultaneously rehabilitating the pipeline.
  • the devices shown in the drawing for draining the rainwater striking a road surface (2) consist essentially of road drains (6) arranged along the curbs (4) at regular intervals, each of which has a sewer pipe (8) with a greater depth below the rainwater channel (10) guided on the road or to one of several control shafts (12) arranged at greater intervals along the rainwater channel (10).
  • the waste water pipe (8) each has a one-piece, flexible hose piece (14), the upper end (16) of which is connected to an outlet opening (18) of a street gully (6).
  • the lower end (20) of the tube piece (14) can open directly into the rainwater channel (10) or into one of the control shafts (12) at its inlet opening (24), or, as in Figure 2 shown, leading into a pipe (22) leading to the rainwater channel (10), so that it is not absolutely necessary, for example, when the street gullies (6) are laid as part of a widening of the road, the construction pit (2) to the rainwater channel (10 ) to dig out.
  • waste water line (8) makes it easier to pass the waste water line (8) between existing obstacles, for example between gas or district heating lines (24) laid along the road, and power and telephone cables (26) or the like to move around these obstacles without a repeated change of direction as in the known stoneware or PVC pipes requires the installation of a large number of kinked or curved sections, which on the one hand increases the work involved in laying and on the other hand makes the sewage pipe vulnerable (8) against destruction caused by penetrating roots.
  • the piece of hose (14) laid between the street drain (6) and the rainwater channel (10) or the control shaft (12) is rolled up in the form of yard goods or can be delivered on drums and is only cut off at the construction site in the lengths previously determined by measuring.
  • the delivered hose material with a nominal diameter of usually 150 mm can consist of vulcanized rubber as well as a flexible plastic material and preferably has one or more fabric inserts (26), which on the one hand increase the tear resistance and on the other hand together with a correspondingly large wall thickness help to increase the resistance of the hose to a possible kinking or compression by vertical or lateral forces.
  • the strength must not be too great, since otherwise the minimum radius of curvature increases too much and the flexibility during laying is thus reduced.
  • the hose section (14) can be covered over its entire length or part of its length by prefabricated half-shells made of concrete or embedded entirely or partially in precast concrete in which case the soil above is only filled up after the precast concrete has hardened.
  • a ballast bed (32) can first be prepared on the bottom (60) of the excavation pit (21), the gradient of which in the entire area between the street drain (6) and the rainwater canal (10) or the outlet into the pipeline (22) exceeds a predetermined minimum gradient.
  • a bed of ready-mixed concrete (33) can then be applied to the ballast bed (32), in which the underside of the tube piece (14) is embedded prior to setting.
  • further ready-mixed concrete (33) can be applied immediately afterwards or after a certain hardening time to the already partially embedded piece of hose (14), which is vertical after hardening and absorbs lateral pressure forces so that the hose section (14) surrounded by the concrete (33) cannot be compressed.
  • a concrete jacket with a predetermined, uniform wall thickness can also be achieved in that the tube piece (14), as shown in FIG. 5, with a covering (30) made of a thin, flexible and tear-resistant material, for example made of sacking or made of a stable plastic film is surrounded, which is drawn before laying the hose section (14) and after laying the covered hose section (14) on a ballast bed (32) closed at its lower end and filled with concrete (33) from above.
  • a concrete jacket (27) is particularly useful when the hose section (14) has a relatively large gradient, so that the concrete filled into the casing (30) at the top ends by itself between the latter and the hose section (14) downwards flows.
  • the street outlet (6) in the embodiment shown in FIGS. 1 and 6 has a plug-in sleeve (34) inserted into the outlet opening (18) which is inclined downwards. , into which a fitting (36) made of PVC, for example, is inserted so that it forms a connection piece (48) projecting outward beyond the street gully (6).
  • the fitting piece (36) has an outer diameter which essentially corresponds to the inner diameter of the hose piece (14), so that after application of a sliding compound, for example made of silicone, the upper end (16) of said piece is a little way above the fitting piece (36) can be pushed and secured with a hose clamp (38) or hose clamp.
  • this can also have a circumferential surface provided with annularly circumferential notches.
  • connection piece (48) surrounding the outlet opening (18) can be concreted into the shaft floor (39) or into a ring of the street drainage shaft (40) during the manufacture of the street gully (6) with which the upper end (16) of the tube piece is connected.
  • the shaft (40) of the street gully (6) has an outwardly projecting screw connection flange (42), on which, after laying the piece of hose (14), its upper end connected to a corresponding screw flange (44) ( 16) is releasably attached.
  • the lower end (20) of the hose section (14) opens into a control shaft (12) so that access to the lower end (20) of the hose section (14) is possible for maintenance or cleaning work.
  • the connection between the hose section (14) and the control shaft (12) can, as shown in FIG. 3, take place in that the lower end (20) of the hose section (14) is in an obliquely outward and upward direction via a ring segment (46) of the control shaft (12) passing connecting piece (48) is introduced, the inside diameter of which corresponds to the outside diameter of the hose section (14) or is slightly larger than the outside diameter. Any remaining annular gap can be sealed with a rubber seal or with sealing compound.
  • the rainwater channel (10) can be drilled on its upper side or, as shown in FIG. 7, on its shoulder with a diamond drill bit, whose diameter corresponds to the inside diameter of the hose section (14).
  • an elastic sealing compound (58) can be filled into the annular gap between the receiving opening (56) and the hose section (14).
  • a tubular covering made of sack canvas (30) pulled over the tube piece (14) was sealed there against the peripheral surface of the connecting piece (48) before the concrete (33) from the upper end (16) of the tube piece between the tube piece (14) and the Wrapping (30) was filled.
