PROBLEM TO BE SOLVED: To provide a spiral pipe forming strip-like member striding over a large number of T-shaped ribs longitudinally provided on the side of the outer surface of a spiral pipe to be formed to be capable of being fitted in the gaps between the T-shaped ribs without projecting a reinforcing material and a method for lining the spiral pipe by using the strip-like member. SOLUTION: In a spiral pipe forming strip-like member 10 having joining parts 10A, 10B formed to both side edge parts thereof and spirally wound to mutually join the adjacent joining parts 10A, 10B to form a spiral pipe, a large number of T-shaped ribs 11A 11F different in height are longitudinally provided on the surface arranged on the outer surface side of the spiral pipe and a reinforcing material R1 strides over T-shaped ribs 11D-11F small in height to be freely fitted in the T-shaped ribs so as not to protrude from the outer peripheral surface between the T-shaped ribs 11B, 11C large in height. |
