TUBE FOR REGENERATION OF EXISTING PIPE, LINING PIPE FOR REGENERATION OF TUBE LAMINATING TUBE FOR REGENERATION, AND METHOD OF REGENERATION OF EXISTING PIPE

摘要

PROBLEM TO BE SOLVED: To surely heat a lining pipe for pipe regeneration to a predetermined temperature, and to regenerate an existing pipe while assuring the quality even if under the environment where effluent such as sewage flows in the existing pipe.;SOLUTION: To the inner circumference surface of an existing pipe K laid underground in the earth, when fixing a lining pipe 10 for pipe regeneration inserted in the inside of which by carrying out heating and pressurization, a tube 11 for regeneration of an existing pipe is made to intervene between an existing pipe and a lining pipe for pipe regeneration. The tube for regeneration 11 comprises forming in a pipe shape a laminated sheet made of an inside thermal barrier layer 12 which has heat insulation properties; a middle impermeable layer 13 which has water interception properties prepared in the outside of the inside layer and a protective layer 14 which is prepared in the outside of the impermeable layer and reinforces the impermeable layer.;COPYRIGHT: (C)2008,JPO&INPIT
