PROCESS AND DEVICE FOR FORMING A CYLINDRICAL LINING IN AN ELONGATED CAVITY

摘要

A remote-controlled and/or programmable pipemaking device (3) is introduced into the cavity (2) and moved forward. The pipemaking device (3) produces the cylindrical lining (5) in the elongated cavity (2) from a strip-like construction element (11). To repair a damaged pipeline (1a), a pipe-bursting device (60) is connected to the pipemaking device (3). The damaged pipe (1a) is expanded and then provided with a lining (5) by the pipemaking device (3). A remoted-controlled and/or programmable advance working device (45) can be moved along a predetermined section through the unbroken ground to form an elongated cavity (2). A cylindrical lining (5) for the elongated cavity (2) is made from a strip-like construction element (11) by a pipemaking device (3) which is movably connected to the advance working device (45). This process is carried out using a pipemaking device which makes a pipe directly in the elongated cavity (2) by coiling the strip-like construction element (11) into a spiral.
