<p>PROBLEM TO BE SOLVED: To provide a segment for a rehabilitation pipe, which enables smooth filling of a filler.SOLUTION: In a segment, an inner surface plate configuring an inner peripheral surface, side plates erected at a peripheral edge of the inner surface plate, and an end plate are integrally formed of plastics. An existing pipe is rehabilitated by coupling the segments together in a circumferential direction and a pipe length direction. A plurality of notches 102c, 103c and 106b for allowing the passage of a filler are formed at upper edges of the side plates 102 and 103 and an upper edge of the internal plate, respectively. The filler for being infilled into a gap between the existing pipe and a rehabilitation pipe when the rehabilitation pipe is laid in the existing pipe flows in or flows out via the notches.</p> |
