<p>PROBLEM TO BE SOLVED: To provide a tube for lining the inner wall of a pipe which curtails setup work in on-site construction to facilitate work for fitting the tube to an inversion guide pipe, smoothes the inversion action of the tube, facilitates work for connecting a string body, and improves reliability. SOLUTION: One end part of the tube 10 for lining the inner wall of the pipe which is fitted externally to the inversion guide pipe 2 is made to be the expansion part 10b of the tube 10 which is formed in the inside diameter T1 of the tube the diameter of which is slightly larger than the outside diameter R2 of the pipe 2. Between the expansion part 10b and the main body part 10b of the tube 10, a tube inversion cutting part 10c which is inserted into the expansion part 10b while being inverted is formed. The other end part of the tube 10 is folded in the longitudinal direction of the tube 10 to form an oyerlap part, in which an engagement hole part 10d for connecting the string body is formed.</p> |
