发明名称 METHOD FOR LINING A PIPELINE, IN PARTICULAR A SEWER
摘要 <p>Method for lining a pipeline (1), in particular a sewer, by means of a deformed pipe liner (4) section (2) with a wall made of thermoplastic material, comprising inserting the pipe liner section (2) into the pipeline (1), shutting off the pipe liner section at its ends, in a first step supplying a heating and pressure medium to the inside of the shut-off pipe liner section, for the purpose of supplying heat to the pipe liner section (2) and exerting a first pressure on the pipe liner section (2), so that the latter comes to rest against the inside of the pipeline (1), and in a second step, after the wall of the pipe liner section (2) has reached a predetermined temperature profile and the supply of heat has ended, supplying a pressure medium to the inside of the shut-off pipe liner section (2), for the purpose of exerting a second pressure on the pipe liner section (2), which second pressure is higher than the first pressure. In this case the second pressure is increased gradually.</p>
