<P>PROBLEM TO BE SOLVED: To provide a method of regenerating an existing pipe conduit which enables a reliable repair of damaged parts by utilizing one open end of existing pipe conduit. <P>SOLUTION: A preceding fixing device 4 having a fixing tube 12 expandable and shrinkable in the radial direction of the device and a traction wire 22 connected to the preceding fixing device 4 are inserted from the open end 2b of existing pipe conduit 2. The preceding fixing device 4 is fed to a closed end 2a deeper than a damaged part 3 in the existing pipe conduit 2, and the fixing tube 12 is expanded at the position to bring the preceding fixing device 4 into surface-contact with the inner peripheral surface of the existing pipe conduit 2 so as to fix the same device in an immovable way. A repair machine 5 is moved to a position corresponding to the damaged part 3 by drawing the repair machine 5 to the side of the preceding fixing device 4 by using the traction wire 22. The repair machine 5 is expanded so as to press a regeneration material 31 onto the inner peripheral surface of the existing pipe conduit 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
