SEGMENT MEMBER FOR REGENERATING PIPE

摘要

PROBLEM TO BE SOLVED: To achieve improvement of water tightness in a coupling part in a segment member for a regenerating pipe coupled circumferentially and longitudinally along the regenerating pipe for regenerating an existing pipe. SOLUTION: In a segment member 1, the outside surface of a side plate 102 which is a coupling surface on one side of a pipe length direction is provided with a projection 102c projected from the outside surface and a recess 102d recessed from the outer surface continuous with the projection 102c. The outside surface of a side plate 103 which is the coupling surface on the other side is provided with a recess 103c and a projection 103d fitted into the projection 102c and the recess 102d, respectively. When the segment members 1 are coupled longitudinally to each other along the pipe, the recess 103c and the projection 103d of the side plate 103 of the segment member 1 on the other side can be fitted to the projection 102c and the recess 102d of the side plate 102 of the segment member 1 on one side in an intimate surface contact state.
