Method for linking pipe segments

摘要

A linking tool (20) links segments (1, 1') for a rehabilitating pipe (42) for rehabilitating an existing pipeline (41). The segment is integrally formed at least from an internal surface plate (101) that constitutes the inner circumferential surface of the rehabilitating pipe, and side plates (102, 103) that have an insertion hole (102a, 103a) formed thereon and are disposed on both sides of the internal surface plate so as to extend in the circumferential direction of the pipe. The linking tool includes a tubular linking pin (21) that is separable into pin halves (22, 23) and can be inserted into the insertion hole (103a) in the side plate (103) of a first segment (1) with a part of the linking pin remaining outside the first segment. The linking tool further includes a separating pin (24) that can be inserted into the linking pin (21) to separate the linking pin into the pin halves (22, 23) and press them against the first segment for anchoring thereto. The pin halves remaining outside the first segment (1) are snap-fitted into a second segment (1') through the insertion hole (102a) of the side plate (102) thereof, thereby linking the first and second segments (1, 1') in the longitudinal direction of the rehabilitating pipe.
