Abstract
A segment for a rehabilitation pipe includes 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. The segments are linked in a circumferential direction and in a pipe-length direction to install a segmental rehabilitation pipe inside an existing pipe. The end plates are provided with an insertion hole through which a linking member is inserted for linking the segments in the circumferential direction. Separately from the insertion hole, the end plates are further provided with an opening for passing therethrough a filler material injected into a space between the existing pipe and the rehabilitation pipe.
