INTERMEDIATE MEMBER FOR CONSTRUCTION METHOD OF REVIVING PIPE

摘要

PROBLEM TO BE SOLVED: To provide an intermediate member which is easy to insert in advance to arrange between an existing pipe and a new reviving pipe before inserting the new reviving pipe, smooths insert of the new reviving pipe, and is also optimum for stabilizing a position after inserting the new reviving pipe in a construction method which revives the existing pipe by inserting the new reviving pipe.SOLUTION: The intermediate member is inserted in advance before inserting a new reviving pipe to arrange between an existing pipe and the new reviving pipe in a construction method which revives the existing pipe by inserting the new reviving pipe in the existing pipe. The intermediate member for a construction method of reviving a pipe is constituted by laminating to integrate an outer circumferential layer composed of a porous polymer material having flexibility and deformability in a thickness direction and an inner circumferential layer composed of a resin sheet A by face bonding.
