摘要： PROBLEM TO BE SOLVED: To provide a pipeline regenerating method capable of lining a fitting pipe 14 without temporarily fixing a water shut-off member 10, eliminating a leakage of water due to looseness in an attachment part and a press-bonding part caused by sharing the pipeline and a change with the lapse of time, and eliminating anxiety that a water shut-off member is fallen. SOLUTION: A cheese-type water shut-off member 10 is used for a construction for lining an existing pipe 16, and shuts off water in a main pipe 12 side end of a fitting pipe 14 divided from a main pipe 12 forming the existing pipe 16. A cylindrical sleeve 24 structuring the cheese-type water shut-off member 10 is inserted into the fitting pipe 14. A thermoplastic fixed part 22 structuring the cheese-type water shut-off member 10 has the outer surface having the nearly same curvature with a curvature of the inner surface of a main pipe lining 18. The fixed part 22 is formed so that a projection shape of the fixed part 22 projected from the axial direction of the main pipe 2 is formed into an arc longer than a half of the circumference. The fixed part 22 is also deformed so that a cross sectional shape of the cheese-type water shut-off member 10 becomes smaller than a cross sectional shape of the main pipe 12. Shape of the deformed fixed part 22 is restored by heating. COPYRIGHT: (C)2008,JPO&INPIT
