Definitions

  • the invention relates to a sealing sleeve and its use in connecting house drain lines to the public sewer system.
  • House drain pipes are usually laid in such a way that first a trench is dug from the house to the collector and the pipes are placed on the bottom of the trench.
  • the connection to the collector is made by prefabricated branch pipes in the collector.
  • a sealing sleeve and a method for the elastic connection of branching pipelines to a main water pipe using this sleeve are known (cf. FR 1.411.607).
  • the sleeve is placed on the end of the branch pipe and pushed together with the pipe from the outside into a pre-drilled hole in the wall of the main line.
  • An annular bead located on the outside of the sleeve causes on the one hand that the sleeve is not pressed into the pipe, and on the other hand that the branch pipe can be pushed firmly into the sleeve.
  • a disadvantage of this sleeve and its use is that both the sleeve and the branch pipe have mutually corresponding annular beads and depressions and must therefore be brought together with care so that sufficient tightness is achieved.
  • the task was to find a connection method which is simple to carry out and provides a reliable seal.
  • the invention thus relates to a sealing sleeve, which is described in the claims, and a method for its use.
  • the sleeve according to the invention is a tubular, externally cylindrical body, in which one side is closed by a thin elastic membrane. On the side opposite the membrane, the edge is provided with a bulge projecting outwards.
  • the inner wall is also cylindrical in the upper area, but conical in the lower part. The wall thickness increases from approx. 23 of the wall length from the bead side to the closed side.
  • the cylindrical part of the inner wall thus has a length of preferably two thirds of the total length of the sleeve, measured from the bead side.
  • the size of the sealing sleeve depends on the diameter of the pipes to be connected.
  • the clear width of the sealing sleeve is dependent on the diameter of the house drain line and the length of the sleeve is dependent on the diameter - and the resulting wall thickness - of the collector. For example, if there is a plastic relining pipe in a stoneware collector, the sealing sleeve is particularly long.
  • the wall thickness of the sleeve on the bead side is 9 to 10% of the inside diameter and increases by 20 to 30%, preferably 25%, towards the closed end.
  • the height and width of the bead are 5 to 15%, based on the clear width.
  • the sealing membrane is 0.2 to 1.0 mm thick, depending on the material from which the sleeve is made.
  • the sealing sleeve according to the invention consists of a rubber-elastic material, for example polychloroprene.
  • a preferred sealing sleeve for a house drain pipe made of a 180 mm thick pipe made of polyethylene has the following dimensions:
  • the sealing sleeve is intended for pipes made of conventional materials in which a relining pipe is located.
  • the method for using the sealing sleeve according to the invention is carried out in this way. That the house drain pipe is chamfered on the outside towards the collector to a cone, the length and angle of the cone with the corresponding dimensions in the sleeve match. The pipe end is then inserted into the sealing sleeve as far as it will go on the end membrane. Then, from a pit dug in a suitable place - if the collector is not accessible - towards the collector - or from the collector - if the collector is accessible - towards the house, a well is drilled. The diameter of this hole corresponds at least to the total diameter of the sealing sleeve in the ground, but in the collector wall to the diameter of the cylindrical part of the sleeve.
  • the house drain pipe is now - sleeve first - pushed from the house through the hole until the sleeve with the bead rests on the outside of the collector wall.
  • the end membrane is pierced.
  • the conical surfaces of the pipe and sleeve cause the sleeve to be distended and pressed firmly against the wall of the bore in the collector wall.
  • the sleeve material forms an all-round sealing bead.
  • the conical pipe end protruding into the collector is cut off at a sufficient distance from the inner wall of the sewer - if the sewer is not accessible by means of a cutting robot.
  • FIG. 1 The figures show a sealing sleeve according to the invention ( Figure 1) and the processes in its application ( Figure 2).
  • the sleeve (1) according to FIG. 1 has a smooth cylindrical outer wall (2) and an inner wall (3) which is also cylindrical in the upper region and conical in the lower third.
  • the sleeve (1) closes at the top with a bead (4), while it is closed at the bottom by a closing membrane (5).
  • FIG. 2 shows the connection of a house drain line to a renovated. i.e. a collecting duct containing a retracted plastic pipe.
  • the house drain pipe (6) which is provided with a cone (7) at the front end, was pushed into the sleeve (1) up to the stop on the end membrane (5).
  • the house drain pipe (6) and sleeve (1) were fed through the collector pipe (8) and the plastic pipe (reliner) (9) until the bead (4) was tight against the collector pipe (8).
  • the house drain pipe (6) has been pushed through the sleeve (1) so that it has been pressed firmly against the pipe (9) and forms the bead (10).
  • the protruding ends of pipe (6) and sleeve (1) have already been cut off.
  • the sealing sleeve according to the invention brings about a moisture and chemical resistant seal between the house drain pipe and the collecting sewer pipe.
  • the connection is somewhat elastic and can therefore absorb small settlements and displacements.
  • the sleeve is easy to use, so that safe installation results can be expected.
  • the end membrane has the advantages that it can serve as a stop for the house drain pipe and also that no dirt can get into the house drain line during installation.
  • the sealing sleeve according to the invention enables refurbishment of defective house drain pipes without extensive open earthwork.
