Abstract:
1. A method for linking segments for a rehabilitating pipe for rehabilitating an existing pipeline, the segment being integrally formed at least from an internal surface plate that constitutes the inner circumferential surface of the rehabilitating pipe, and side plates that have an insertion hole formed thereon and are disposed on both sides of the internal surface plate so as to extend in the circumferential direction of the rehabilitating pipe, the method for linking the segments comprising the steps of: preparing a linking pin that can be separated into pin halves by a separating pin; inserting the linking pin into the insertion hole in the side plate of a first segment with a part of the linking pin remaining outside the first segment; separating the linking pin into the pin halves by the separating pin, the separated pin halves being pressed against the first segment, thereby anchoring the pin halves to the first segment; and snap-fitting the pin halves remaining outside the first segment into a second segment through the insertion hole of the side plate thereof, thereby linking the first and second segments in the longitudinal direction of the rehabilitating pipe.
