Method for lining a pipe conduit or a duct

Abstract

A process for lining a pipeline, comprising the following steps: pouring in an adhesive, introducing the tube with inversion into the pipeline by applying pressure, providing the conditions for the adhesive situated on the outside of the tube by irradiation using energy-containing waves, and maintaining the internal pressure in the introduced tube until the adhesive is cured, severing the connection between the tube and a retaining strap, which extends through the entire tube in the longitudinal direction thereof, at the end which is at the front in the direction of movement of the tube after the tube has been introduced, coupling the severed end of the retaining strap outside the pipeline to a radiation unit, using the retaining strap to pull the radiation unit, in the non-activated state, through the tube as far as the end thereof which is at the rear in the direction of movement of said tube, pulling the supply cable for the radiation unit into the tube behind said unit, and then using the supply cable to pull the radiation unit, in the activated state, through the tube.
