METHOD FOR RECLAIMING PIPE LINE, RECLAMATION MATERIAL USED THEREIN, AND METHOD FOR PRODUCING RECLAMATION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for reclaiming a pipe line which does not largely increase a time necessary for the reclamation of the pipe line even when the thickness of a reclamation material is increased, to provide the reclamation material, and to provide a method for producing the reclamation material.;SOLUTION: In the method, the flexible cylindrical reclamation material (liner 13) having inner layer resin-impregnated felt 17 or inner layer resin- absorbed felt 18 on the outside of or between films of sheets (inner layer impermeable films or sheets 19) is pushed to the inner wall surface 10b of a pipe (underground pipe 10), and the curable resin is cured to reclaim the pipe line 1. The progress of the curing of the resin is made different in the thickness direction of the reclamation material 13, and the curing on the outside of the reclamation material 13 is accelerated as compared with the curing on the inside of the reclamation material 13.;COPYRIGHT: (C)2002,JPO
