摘要

PURPOSE: To repair a long and narrow pipe line, such as a pipe branched from a main pipe, from the ground without conducting excavation. ;CONSTITUTION: Tube curing devices 20, 20 are connected to the rear end of a photosetting lining tube 10 by a resin tape 26 that can be fused. The lining tube 10 is inserted into a pipe line from the ground while being reversed. After insertion, the resin tape 26 is fused by a remote operation from the ground. The tube curing devices 20, 20 are separated from the lining tube 10. While the tube curing devices 20, 20 are pulled back to the ground, the lining tube 10 is cured by the tube curing devices 20, 20. In this manner, all operations are carried out on the ground.;COPYRIGHT: (C)1994,JPO&Japio
