<p>PURPOSE:To attain reduction of a cost of equipment by repairing a damaged part of a pipe line by a lining material increasing a temperature by heat generated by chemical reaction between a thermal medium and liquid in an air bag, so as to eliminate necessity for an equipment circulating a heating medium of hot water or the like. CONSTITUTION:In case of repairing a defective part 1a in a pipe line of sewerage or the like, a pipe partially repairing member 3 is introduced into the pipe line 1, thereafter a towing rope 5 is pulled to extract a lining material cover 14, and then water through a hose 17 successively compressed air through the hose 17 is supplied into an air bag 11. In this way, the air bag 11 is inflated to closely attach a lining material 13 to an internal wall surface including the defective part 1a in the pipe line 1, also to harden a water stop agent by bringing leak water into contact with the water stop agent with which a water stop agent impregnation layer 26 is impregnated. By generating heat by chemical reaction of burnt lime 15 with water in the air bag 11, the linging material 13 is heated to harden a thermosetting resin with which a resin impregnation layer is impregnated.</p> |
