  • Strip member for spiral pipe and rehabilitation method of existing pipe
    Patent number: 11473714
    Abstract: A strip member that can be made into a spiral pipe with an enlarged perimeter by being spirally wound. A first fitting portion (93) is disposed in one end portion of a cross-section orthogonal to an extending direction of a strip member (90) and a second fitting portion (94) is disposed in the other end portion of the cross-section. A spiral pipe (9) is made by spirally winding the strip member (90) and fitting the second fitting portion (94) with the first fitting portion (93) preceding by one turn. The strip member (90) has a cross-sectional configuration in which a reference width direction W9 connecting the first fitting portion (93) and the second fitting portion (94) on the cross-section is inclinable to an outer surface side toward the first fitting portion side when the strip member is wound.
