UNDERGROUND BURIED PIPE REPAIRING METHOD |
摘要 |
PROBLEM TO BE SOLVED: To provide an underground buried pipe repairing method for easily repairing an underground buried pipe with simple work. SOLUTION: The ends 3, 4 in the curved direction of an elastic base material 2 are connected to each other from the tip side by a connecting means to sequentially form a tubular repairing material 1. After inserting the tip side of the tubular repairing material 1 into the underground buried pipe 16 from one opening, while forming the tubular repairing material 1 sequentially toward the rear end side, the tubular repairing material 1 is moved to the other opening side of the underground buried pipe 16. The tubular repairing material is thus arranged from one opening to the other opening of the underground buried pipe 16. COPYRIGHT: (C)2007,JPO&INPIT
