Definitions

  • the invention relates to a pipe system with jacking pipes and a connection with a sleeve-like guide ring and spigot at the pipe joint, in particular for sewage pipes.
  • the guide ring is attached to one end of the pipe, is mostly made of steel, sometimes also plastic, and has the same outer diameter as the jacking pipes.
  • the tip end has an outer diameter which is chosen to be correspondingly small, so that the tip end can be inserted into the guide ring with sufficient play.
  • Such pipes are also suitable for other water pipes.
  • the pipe jacking is known in various forms. Usually a starting shaft and a
  • the individual tubes are pressed forward.
  • Pressing pressure is transmitted from one pipe end to the other by a power transmission ring
  • Transfer pipe end Usually it is wooden rings.
  • the power transmission rings remain between the pipe ends.
  • Waste water pipes that are not jacking pipes mostly have a socket connection.
  • the socket connection between two pipe ends consists of a socket or pipe bell and
  • the sleeve or pipe bell is on one pipe end, the spigot on the other pipe end of the connection.
  • the seals should close the gap between the socket or pipe bell and the tip end. From EP 677690 AI it is known to use two seals, and the
  • Wastewater pipes are not known. Nevertheless, the same leakage problem arises with jacking pipes.
  • a rubber seal is provided between the end faces (pipe mirror) of the pipe ends.
  • the rubber seal should be activated.
  • a multi-seal and repairable seal on jacking pipes is achieved in that two ring seals are arranged at a distance from each other in the gap between the guide ring and the tip end and the intermediate ring gap can be acted upon with a test medium and filled with a sealant.
  • a sealing ring and or several sealing rings can also be provided between the end faces of the two pipe ends in a special manner explained below.
  • activatable ones can be used
  • Sealing rings may be provided.
  • the sealing rings can be designed as hollow profiles and provided with an activation agent.
  • Activatable sealing rings are known per se. Examples are EP 0479172 B1 or EP 0340659 AI and DE
  • Pressure should be set or, with sufficient pressure, close to the associated one
  • the sealing rings usually consist of permanently elastic material.
  • Styrene-butadiene rubber (short form SBR) or ethylene-propylene-diene mixed polymer (short form EPDM) is preferably used.
  • Permanently elastic and compressible sealing materials are, for example, silicone and acrylic sealing materials.
  • a bentonite suspension can also be pressed into the sealing rings. The bentonite suspension has the advantage of being repressible.
  • the sealing rings can lie in recesses in the tip end and / or in recesses in the guide ring and / or in recesses in the force transmission ring.
  • a multi-part design of the power transmission ring is also advantageous. At least two concentrically arranged rings are provided, between which a distance is provided for the arrangement of a sealing ring. In addition, an arrangement of a sealing ring on the inside and / or the outside of the power transmission ring is possible.
  • Air for example, is suitable as test equipment.
  • a certain pressure can be built up and a certain period of time can be selected as a benchmark for the seal, for which the sealing system maintains the air pressure without any significant pressure loss.
  • test equipment and / or sealant is supplied via one or both sealing rings or one or more separate supply lines are provided for supplying the test equipment and / or sealant.
  • Common and different supply lines can be provided for the test means and the sealant.
  • feeds / lines for test equipment and / or sealants can be guided in the longitudinal direction and / or in the circumferential direction and / or in the radial direction through the pipe jacket and / or the guide ring and / or the tip end.
  • Several jacking pipes, if necessary all jacking pipes can be provided with common feeds / lines. Then a coupling of the lines is provided at the pipe ends. Connectors can also be used as a coupling.
  • the design is also used to visually inspect a complete filling of the cavity to be sealed.
  • the test can be carried out using sealant that emerges from the test medium supply after the cavity has been completely filled.
  • the sealing rings can be pulled / pushed onto the spigot end after the jacking pipes have been completed.
  • the production takes place in a mold.
  • the sealing rings can also be inserted into the mold during manufacture and can thus be enclosed by the concrete. This procedure is recommended if the gap between the tip end and the guide ring is very narrow and / or if the sealing ring cross-section is relatively large and / or if the sealing ring does not survive an expansion associated with the mounting without permanent deformation and / or if the sealing ring is anchored in the Concrete is desired and / or if the subsequent incorporation of a groove for the sealing ring involves additional work and / or if the sealing ring is connected to one or more test lines and / or other lines.
  • the sealing rings can have a closed profile cross section. A distinction must be made between the full profile cross section and the hollow profile cross section.
  • the hollow profile cross section has a cavity on the inside, preferably tubular profiles are used as hollow profile cross sections.
  • the lines leading to the sealing ring for test equipment and sealants preferably consist of the same material as the sealing ring and are welded or glued to the sealing ring.
  • Combined sealing rings can also be used, e.g. Consists of an annular full profile, which forms the sealing surfaces, and a hose profile that can be pressurized with a pressure medium / sealant.
  • the hose profile can perform two tasks: firstly, create an even circumferential pressure on the sealing ring, secondly, guide the sealant to any leakage points.
  • the hose profile is constantly pressurized with air pressure.
  • the air pressure can be readjusted continuously or at intervals.
  • the model for this cross-sectional training are the automotive tires as open cross-sections.
  • the car tires form a closed cavity with the rim.
  • the sealing rings can form a closed cavity with the tip end or the guide ring when they are in contact there.
  • the profile cross-section can be a motor vehicle tire be reproduced or deviate from it round and / or angular.
  • U-shaped or W-shaped or M-shaped profile cross sections can result.
  • Such sealing rings form a seal in the manner of a labyrith seal with a plurality of sealing lines running around one another.
  • the profile cross-section can also be composed of several adjacent M-shapes or W-shapes.
  • Such sealing rings can be pushed / pulled with the open cross-sectional side over the outlet openings of the lines / feeds for test equipment and sealants. This is favorable for lines / feeds that have been molded into the jacking pipes.
  • such sealing rings are provided with a special seat in the tip end or in the guide ring, corresponding to the seat of a motor vehicle tire in the rim.
  • the lines / feeds for test equipment and / or sealants on the jacking pipe are provided with a releasable closure at least on the inlet side. This enables a clean connection of additional lines / feeders.
  • the closure can act in both directions.
  • One-way closures are also possible, e.g. Check valves.
  • Check valves can also be provided on the outlet side of the lines / feeds. This is advantageous if several lines / feeds are provided for pressing the sealant and if the sealant solidifies to such an extent that, after at least a time, it is no longer possible to inject from the same line / feed. In this case, the repressing can be carried out by another feed which has not yet been subjected to sealant and on which the check valve arranged on the outlet side has prevented undesired penetration of sealant.
  • the lines / inlets that open on the inside of the pipe at the ends facing away from the sealing rings are accessible from there.
  • the maintenance team can carry out the leak test and repress the seals from the inside of the pipe. It is favorable if the mouth openings of the feed lines are above the water level. This counteracts calcification and soiling of the openings.
  • the leak test and re-grouting can be carried out by a robot.
  • Commercial robots have one Optics / camera with which the robots are controlled by sight, and tools for drilling and sealing as well as for receiving and dispensing sealants.
  • the robot can be equipped with a pressure container for compressed air.
  • Pressure vessels can absorb the compressed air for the leak test and release it for the test processes after connection to the corresponding lines.
  • a pressure vessel is suitable for storing the sealant in the robot. It is advantageous if the pressure vessel is divided with a membrane, so that part of the
  • Pressure vessel that borders on the membrane can be filled with compressed air.
  • the compressed air is further compressed when the other part of the pressure vessel, which borders on the membrane, is filled with sealant.
  • the compressed compressed air forms a pressure source and supplies the pressure required for re-injecting sealant after connection to the relevant line / feed.
  • the necessary pressure can also be generated with a pump.
  • the pressure can act on the sealant directly or indirectly, as with membrane technology. In the event of direct action, the sealant is conveyed through the pump, thus building up the pressure.
  • the known robots are self-propelled and can be controlled remotely.
  • the remote control can be a radio remote control or a cable remote control.
  • the supply station for the robot can be set anywhere within wide limits.
  • the robot can always return to the supply station.
