发明名称 PIPE CONDUIT RECLAMATION METHOD
摘要 PROBLEM TO BE SOLVED: To provide a pipe conduit reclamation method enabling not only reinforcement of old water-and-sewage pipes or gas conduits mainly buried in the ground but also correction of the deformation of existing pipe conduits. SOLUTION: The pipe conduit reclamation method includes the processes of: setting a pipe conduit-correcting apparatus 2 having an expansive function for expanding an abutting portion 3 in a radial direction R of a liner 1 for pipe conduit reclamation therein in the deformed portion of an existing pipe conduit 130; heating and pressurizing the deformed portion from the inside of the liner 1; correcting the deformation of the conduit 130 from the inside of the liner 1 by expanding the abutting portion 3 of the pipe conduit-correcting apparatus 2; and cooling the liner 1 in such a state that the abutting portion 3 of the pipe conduit-correcting apparatus 2 is expanded.
