Filed: 2003-06-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide a pipe opening water-proof structure and a pipe opening water-proofing method of a regeneration pipe capable of securing water proof near the pipe opening of the regeneration pipe easily and for a long period of time while shortening construction time duration.  <P>SOLUTION: In a pipe opening water-proof structure of the regeneration pipe, water in the pipe opening of the regeneration pipe for regenerating inside of an existing pipe is stopped with respect to the existing pipe. Between the pipe opening of the existing pipe and the pipe opening of the regeneration pipe, a water-proof material made of crosslinking rubber for sealing the gap between them with a substantially uniform thickness over the circumferential entire region is disposed. The seal-like water-proof material made of crosslinking rubber is adhered to the inner peripheral surface of the pipe opening of the existing pipe before diameter expansion of the regeneration pipe or the outer peripheral surface of the pipe opening of the regeneration pipe with the substantially uniform thickness over the circumferential entire region. Then, by expanding the diameter of the regeneration pipe, the pipe opening of the existing pipe and the pipe opening of the regeneration pipe are adhered to each other and sealed by the water-proof material rubber.  <P>COPYRIGHT: (C)2004,JPO
