Abstract
In a pipe rehabilitation method, segments are linked in the circumferential and pipe-length directions to install a rehabilitation pipe inside an existing pipe. Nuts are secured to the segments along the circumferential direction thereof. Linking members each configured to be screwed into one of the secured nuts are inserted into each segment. Each linking member is temporarily locked to the segment to prevent the inserted linking member from falling out of the segment. The segment into which the linking members are inserted and temporarily locked and one of the segments to which the nuts are secured are aligned relative one another, and the linking members are screwed into the respective nuts to fasten both segments together and link them in the pipe-length direction.
