Definitions

  • the invention relates to a method and a device for lining, in particular for the purpose of renovation, of pipelines, wherein a film or fabric material and a hardenable medium are used.
  • a method of a device for lining elongated openings through a winding tape is known, tubes with different diameters and cross sections being produced by the winding device.
  • the winding tape is fed to the winding device and wound spirally to form a lining.
  • the winding tape which is shaped as a spiral, is brought forward in such a way that the profiled tape is transported forward by the rotation of a double tube provided with a screw thread in connection with a drive roller and a counter roller and is fed to a joint, in which it is assembled via a pressure roller and pressed against a shield tail seal becomes.
  • the wound tube After the wound tube has emerged from the shield tail, it is expanded to the final shape by calibration rollers, which are mounted on movable supports, and the inner lining produced in this way is brought into contact with the inner wall of the opening to be lined.
  • This resulting in an indirect positioning of the winding tape on the inner wall of the pipeline to be lined has the disadvantage that a complicated device is required to carry it out, which drastically affects the economy of the known method.
  • the known method does not provide sufficient flexibility with regard to the shape of the inner lining.
  • EP 0 228 998 describes a method and a device for the renovation or manufacture of installed pipelines, a three-layer hose being used for the subsequent inner lining of the defective pipe, which consists of an inner and an outer layer, at least one of which is radiolucent and at least one is gas-tight, and consists of an intermediate layer impregnated with UV-radiation-resistant resin.
  • the three-layer hose which has already been formed, is introduced into the pipeline to be rehabilitated through a mountable first shaft, and the radiation-curable resin is cured in the inflated state of the hose with the aid of UV radiation.
  • This blowing up and hardening of the hose is carried out by pulling a device with a pulling rope attached in the longitudinal axis of the pipe through the hose inserted into the pipe, which has a conical run-up and widening surface on its end face.
  • the hose lying on the traction cable is spread out from the inside in a circle from this run-up and expansion surfaces to the pipe wall and pressed to the pipe with compressed air or with crowned rollers and at the same time caused to harden by UV radiation emitted by a radiation source of the device.
  • the known method has the disadvantage that the three-layer hose which is manufactured outside the pipeline and which is to be inserted into the pipeline to be rehabilitated in the prefabricated state is only extremely cumbersome and therefore difficult to handle:
  • a walk-in at both ends thereof and therefore a relatively large shaft must be available so that the three-layer hose can be inserted into the pipeline to be rehabilitated, and so that two deflection rollers can be installed so that the three-layer hose from one shaft can be deflected accordingly to the opposite shaft by the pulling rope moving the pipeline to be renovated.
  • Pipe sections can be refurbished, since the weight of the hose to be towed by such a pulling device causes a frictional force which counteracts the feed direction and which relatively quickly exceeds the maximum towed load of such a pulling device.
  • Another disadvantage of the known method is that the three-layer hose used here can be produced only with great effort.
  • a device which has a storage drum for an intermediate layer of the hose to be produced around an inner layer, a trough-shaped impregnation section with an impregnating resin, a further device for covering the intermediate layer laid and impregnated with an outer layer and an additional supply roller for a protective jacket of the three-layer hose.
  • the outer layer which is pushed together in the manner of a bellows, is then loosely pushed onto a hollow carrier in sufficient quantity.
  • the intermediate layer laid around the inner layer, flattened and rolled up on the supply roller is drawn into the carrier by means of pressure rollers and held. Then the pressure rollers are back in the resin of the impregnation line is tilted, the intermediate layer - pressed by the pressure rollers - dipping into the resin up to the drive rollers of the impregnation line. Finally, the intermediate layer brought into contact with the outer layer is pulled through the hollow support while the drive for the drive rollers is switched on at the same time. The plastic film forming the outer layer of the three-layer tube is peeled off the carrier and continuously envelops the intermediate layer.
  • Such a complex three-layer hose - which also has a relatively high bending stiffness and is therefore not very flexible - consequently leads to extremely high renovation costs in a disadvantageous manner, so that the known method cannot economically renovate defective pipelines.
  • the multi-layer hose After insertion, the multi-layer hose is sealed airtight at both ends and inflated by blowing in a gaseous and possibly oxygen-free medium and then kept at a constant pressure at which the hose is pressed against the inner wall of the pipeline, but without the expansion limits of the hose to reach.
  • the resin is then UV Radiation source that was placed in the tube before airtight sealing, cured in situ.
  • this known method again has the disadvantage that the prefabricated replacement hose is not only difficult to handle. Rather, it is also extremely expensive to manufacture, since for the purpose of building the renewal hose, a first liquid- and gas-tight inner hose with a hose-like, but UV-permeable outer layer made of felt, fleece or fabric-shaped material in the form of a roll or in layers a container with an upper outlet line is given. A negative pressure which is less than 0.5 bar is then generated in the container mentioned.
  • the hose is slid through a resin trough and soaked and squeezed therein, whereupon the squeezed hose is guided on a web over a glass fiber-reinforced, liquid and gas-tight and UV-impermeable outer hose system.
  • This armored hose outer system is placed around the soaked hose and welded together to form the outer hose layer.
  • a method for the rehabilitation of drain pipes using a resinized inner pipe in which an inner pipe impregnated with a hardenable resin is inserted into the relevant channel section in the axial direction and brought into juxtaposition with the defective channel section.
  • a winding tube is produced outside the duct to be renovated by shaping a resinous plate, the length of which is longer than the axial extent of the duct section to be renovated, into a tube such that the edge regions running in the longitudinal direction of the plate cover a large area overlap.
  • the so formed Inner tube with an initially reduced diameter is placed on a bladder which can be expanded in the radial direction of the duct and is introduced into the duct together with this bladder.
  • the inner pipe is brought in juxtaposition to the rehabilitation section of the sewer and the bladder is then inflated by the supply of compressed air, causing the wrapping pipe lying above the bladder to expand radially and the overlap areas to shift in the circumferential direction.
  • Displacement takes place until the winding tube is in a form-fitting manner on the inner circumference of the sewer section to be renovated.
  • the resin-impregnated inner tube is then cured using UV lamps in the bladder.
  • a method and a device for the lining and wrapping of pipelines and the lining of channels is known, in which by a helical winding of a strip in a ring of rolls to a tube, in which edges of the strip overlap and intermesh so that a longitudinal slip is possible by which the tube can be kept at the desired diameter during application to the pipeline wall, with a winding force being applied to bring about the interlocking edges so that the diameter of the tube can be changed so that it touches the wall of the pipeline.
  • a device for repairing pipes in which a carriage is provided which is guided coaxially to the axis of the pipe to be repaired by two sets of spring-loaded rollers.
  • the carriage has at its front end a connection for a supply hose for the liquid coating material to be applied to the inner wall of the tube and at a rear end a distribution element for the coating material.
  • the connection is via a connecting line with an outlet opening connected to the bottom of the car.
  • a hose for the coating material is drawn in and connected to the above connection of the device. Then the car is slowly pulled through the pipe by the hose, while coating material is simultaneously fed through the hose and applied through openings to the underside of the pipe to be renovated. Due to the distribution element driven by a motor, the coating material is evenly distributed from the lower side of the tube over its inner wall. A subsequent smoothing cone of the known device compensates for the unevenness that is still present.
  • a device for lining, in particular renovation, a pipeline, a magazine device for receiving and storing a plurality of webs of at least one film or fabric strip, a production device functionally connected to the magazine device for on-site formation of an inner lining is preferably used renovating pipeline by directly positioning at least one web of the at least one film or fabric strip on the inner wall of the pipeline, a transport device for moving at least the production device in the longitudinal direction of the pipeline to be renovated, and a curing device for curing a curable that impregnates the film or fabric strip Has medium used.
  • the method and the device according to the invention make it possible in a particularly simple manner to make an inner lining for a pipeline to be renovated from film or fabric strips, that is to say from a tape-like film or fabric material to manufacture directly on site. It is therefore advantageously no longer necessary to prefabricate the inner lining for the pipeline to be lined, in particular to be renovated, in a complex manner before it is installed. Rather, the method according to the invention and the device according to the invention preferably used for this purpose advantageously allow mobile production of a tube functioning as an inner lining within a pipeline by directly contacting the webs of the film or fabric strips with the - possibly coated with a hardenable medium - inner wall of the pipeline to be renovated.
  • the method according to the invention advantageously allows only certain points of the pipeline to be treated selectively, so that it is no longer necessary to rehabilitate an entire section of the pipeline.
  • the savings in film or fabric material achieved through this selective application of the method according to the invention also further reduce the renovation costs significantly.
