<p><P>PROBLEM TO BE SOLVED: To provide a coating body 10 for repairing and an existing pipeline repairing method, capable of always installing the coating body for repairing in an existing pipeline in the best state by facilitating construction work into the existing pipeline 1. <P>SOLUTION: A cylindrical body 20 is formed by facing a base end part 26 to a tail end part 28 of a plate member 22 by curving the plate member 22 in a substantially cylindrical shape. The cylindrical body 20 is covered with an annular elastic member 12 interposed between an outer peripheral surface of the cylindrical body 20 and an existing pipeline inner peripheral surface 2. A pair of inserting members 40 are inserted toward the central part side from both end part sides in the longitudinal direction of the cylindrical body 20 into a clearance part 38 formed of the base end part 26 and the tail end part 28 in this state. The cylindrical body 20 is diametrally expanded by moving the base end part 26 and the tail end part 28. Thus, the coating body 10 for repairing composed of the cylindrical body 20, the annular elastic member 12 and the inserting members 40, is installed in the existing pipeline 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
