Abstract

Segments are linked in the circumferential and pipe length directions to assemble a rehabilitating pipe inside an existing pipe in order to rehabilitate the existing pipe. A plurality of nuts are secured to the segments along the circumferential direction thereof. A fastening member having a screw part is provided which is screwed into the nut to fasten a first segment to a second segment to which the nut is secured, thereby linking the first and second segments in the pipe length direction thereof. The position of the nut in the first segment is offset as viewed in the circumferential direction from the nut position of the second segment. The arrangement of the fastening members and the nuts is staggered as viewed in its entirety. This allows the connection strength of the segments in the pipe length direction to be made uniform.
