摘要

PROBLEM TO BE SOLVED: To avoid formation of a step at pipe bottoms when a pottery pipe or a concrete pipe and a polyvinyl chloride pipe are connected to each other.;SOLUTION: A sewer pipe structure is formed of a first pottery pipe 100, a second pottery pipe 300, and a pipe structure 10 interposed between the first and second pottery pipes 100, 300. The pipe structure 10 is formed of a polyvinyl chloride joint pipe 20 and a repairing pipe 30. The joint pipe 20 and the first pottery pipe 100 are connected together in a manner being butted against each other by an adhesive 60 or the like. The pipe structure further has a pipe bottom coupling member 5 bonded to an internal peripheral surface of the joint pipe 20, for coupling the pipe bottoms of the joint pipe 20 and the first pottery pipe 100. The pipe bottom coupling member 5 has a plate piece 1 formed on a lower side of a pipe center in the internal peripheral surface of the joint pipe 20, so as to be arranged astride the internal peripheral surface of the joint pipe 20 and an internal peripheral surface of the first pottery pipe 100.;COPYRIGHT: (C)2008,JPO&INPIT
