- EP-AI-403 773 provides, at a junction of a lateral feed line in a sewer renovated with an inner pipe, to prevent the ingress of sewage coming from the feed line into the gap between the sewer wall and the inner pipe at the junction parts between the inner pipe and to provide annular or tubular seals on the duct wall.
- EP-Al-350 802 describes a technique in which, for the rehabilitation of pipelines, into which supply lines, for example from house connections, open out laterally, an inner pipe is inserted into the main pipe run, and the annular space formed between the original pipe wall and the inner pipe is poured out with a mortar compound. Thereafter, openings are created from the inside of the inserted inner pipe at the junction points by cutting through the wall of the inner pipe and the mortar layer, and a flow connection is again formed between the junction and the main line.
- connection of the supply lines to the main pipe run remains in its original state and is not changed even when moderate eccentricities occur when the openings are cut out; at best, spraying on a thin layer of synthetic resin on the side surfaces of the transition is considered; A thorough remediation of any errors in the connection of the supply lines to the main line is not intended with this technology.
- the method according to the invention of the type mentioned at the outset is characterized in that, before the sealing compound is introduced at the junction, the edge of the junction is widened by milling out a depression running along this edge, and if appropriate after the flow path of the merging pipe has been made continuous , a cover layer of solid or solidifying, insoluble, corrosion-resistant and aging-resistant material is applied to the inner surface of the mouth. This procedure enables the above-mentioned objective to be met well.
- a tight and firm connection between the house connection pipes and similar inflow pipes opening into the channel and the channel wall can be produced in a simple manner, damage areas present in this area, such as breakouts, transition gaps and cracks or similar damage and also missing parts, which have arisen as a result of displacements between the house connection or inflow pipes and the orifices in the canal wall, can be filled in or eliminated with a high degree of reliability and can be replaced by sealant and thus renovated.
- house connection pipes and similar inflow pipes are often provided with a cleaning shaft some distance from the sewer or main line, in which case an injection device for introducing the sealing compound can be inserted particularly simply into the relevant house connection pipe or inflow pipe.
- one embodiment of the The method according to the invention is advantageous, which is characterized in that an inner tube located in the channel is milled out correspondingly when expanding the edge of the mouth to this extension, and any filling of the annular space between the channel wall and inner tube is also correspondingly milled out, and that the mouth is provided with a cover on the inside of the channel before the sealing compound is introduced.
- Such milling can be carried out both from the inside of the channel or main line and from the house connection pipe or inflow pipe. If necessary, a cover can be provided on the inside of the junction.
- An advantageous variant of the last-mentioned embodiment is characterized in that first the edge of the channel wall is milled to widen at the junction, then an inner tube is inserted into the channel, which also forms a cover for the junction, and then the introduction of the sealing compound is made at the junction. It is also advantageous here if one provides that after inserting the inner tube and before introducing the sealing compound at the junction, the annular space between the channel wall and the inner tube is filled with a filling material.
- the method according to the invention also offers advantages with regard to the formation of the mouth-side end of the house connection pipe or feed pipe at the junction point in the channel or main line in that precise machining of the edge of the house connection pipe or feed pipe on the junction side in accordance with the curvature of the channel wall present at the junction point can be dispensed with .
- This relatively complicated spatial intersection form can be produced automatically when the sealing compound is removed or milled, which is carried out as the flow path is exposed from the house connection pipe into the channel. This represents a very significant simplification of work.
- a related embodiment of the method according to the invention is characterized in that a house connection pipe or feed pipe is left with a distance between its mouth end and the inner wall of the channel to the channel and this distance by the On- bring the solidifying sealing compound at the junction and the removal of the sealing compound present in the flow path of this connecting house pipe or feed pipe is bridged. It is particularly advantageous if this technique is used when an existing house connection pipe or feed pipe is to be provided with an inner pipe.
- a related development of the method is characterized in that an inner pipe of smaller diameter is inserted into an existing house connection pipe or feed pipe, leaving a distance between its mouth-side end and the inner wall of the channel, which inner pipe later the flow path of the relevant house connection or the relevant one Forms supply line, and that the annular space between this inner pipe and the house connection pipe or supply pipe surrounding this inner pipe is filled in the area located at the mouth end of this inner pipe by the solidifying sealing compound introduced at the junction.

- the penetration of the sealing compound into the branches of the cavities present at the junction 9 can be controlled by selecting the injection pressure and also by selecting the composition of the sealing compound.
- Expanding sealing compounds are advantageous. Particularly preferred becomes a sealing compound in the form of a moisture-curing, water-displacing, rapidly solidifying two-component synthetic resin foam, a polyurethane foam which swells and thereby "creeps" particularly well; such a foam penetrates even into 0.1 mm wide cracks and hardens to a material with a considerable static strength.
- foam material of this type which is resistant to aging and resistant to household chemicals and to a chemical attack by substances in the ground and which is of course waterproof.
- Such swelling polyurethane foam comes into contact with relatively large pressure on the surfaces delimiting the foam body and thus prevents water penetration at the contact surfaces and remains elastic to a certain extent, so that even small relative movements can be absorbed without this dense concerns of the foam is significantly impaired.
- Such properties can also be achieved with other materials, but at the present time, above all, polyurethane foam materials with such properties can be obtained without problems in the trade.
