Abstract

PROBLEM TO BE SOLVED: To eliminate the need for disposing of a pipe sealing tool and to make it usable in connecting or repairing service water pipes because it is harmless to human bodies by forming the tool from a material that is water-soluble and harmless to human bodies so that it is dissolved in water or the like and disappears when a certain period of time elapses after use. SOLUTION: This sealing tool 1 is a circular film-shaped body, constructed of a center film part 11 and peripheral curved face parts 12 that face each other on their backs and join to the center film part 11, is thin at the center film part 11, gets thicker toward the periphery, and has flat edges 13 formed on its ends to make it fit closely with the inner periphery of a pipe. The sealing tool 1 is molded using polyvinyl alcohol. The sealing tool 1 takes a melting time of almost two hours, which can be increased or decreased by increasing or decreasing the thickness of the center film part and be set to correspond to the expected construction time. Thus the number of construction processes can be greatly reduced.
