摘要

PROBLEM TO BE SOLVED: To bend and deform a rehabilitation pipe to be newly installed in an old existing pipe, according to the shape of the bent part of the existing pipe.;SOLUTION: In a rehabilitation assisting apparatus 1, an advancing/retreating rod 53 is extended from a main frame 51, and a support part 54 or an attaching part 55 is provided to the tip end of the rod 53 to be integrally bonded to the inner circumferential surface of the rehabilitation pipe 20. An apparatus body 5 is arranged in the pipe shaft direction of the rehabilitation pipe at a plurality of portions at intervals, and furthermore a pin-connected connection frame 6 and an expanding or contracting extension member 7 is installed between the adjacent device apparatus bodies 5, 5. Then, the extension member 7 is extended or contracted, to bring the respective attaching parts 55 of the apparatus bodies 5, 5 closer together or separate them from each other in the pipe shaft direction, causing the rehabilitation pipe 20 to be extended and deformed to follow and deform the shape of the rehabilitation pipe 20 into the bend part shape of the existing pipe 10.;COPYRIGHT: (C)2009,JPO&INPIT
