METHOD FOR LINKING SEGMENTS AND LINKING TOOL

摘要

A linking tool links segments for rehabilitating an existing pipeline. The segment may be formed from an internal surface plate forming the inner circumferential surface of a rehabilitating pipe, and side plates having a hole formed thereon. The tool includes a tubular linking pin separable into pin halves for insertion into the hole in the side plate of a first segment with a part of the linking pin remaining outside the first segment. The tool further includes a separating pin insertable into the linking pin to separate the linking pin into the pin halves and press them against the first segment. The pin halves are snap-fitted into a second segment through the hole of the side plate thereof, thereby linking the first and second segments. Such a tool allows the segments to be efficiently linked in a short period of time.
