Abstract

A segment for a rehabilitation pipe is formed of an inner surface plate having an inner circumferential surface, and side plates and end plates provided upright on a peripheral edge of the inner surface plate. The inner surface plate, the side plates, and the end plates are formed integrally from a plastic material, and a number of such segments are linked in circumferential and pipe-length directions to form the rehabilitation pipe. Each of the side plates is provided with at least one hole through which a linking member is inserted for linking the segments in the pipe-length direction, and is provided separately from the hole with an opening at an end in the vicinity of the end plate for a linking operation of the segments in the circumferential direction and for passing therethrough a filler material injected into a space between the existing pipe and the rehabilitation pipe.
