ABSTRACT:
A rehabilitating pipe is assembled inside an existing pipe using segments to repair the existing pipe. A coupling member is inserted through a segment when it is coupled in the longitudinal direction to another segment coupled already, and the coupling member is joined to the coupling member of another segment already coupled. During joining the segment is clamped against another segment and both the segments are coupled in the longitudinal direction. Such steps are repeated to couple other segments to segments already coupled until the rehabilitating pipe is laid to a predetermined length.
