LINER FOR EARTHQUAKE-RESISTING PIPE JACKING METHOD

摘要

PROBLEM TO BE SOLVED: To prevent the catching of a traction cable to a retaining ring for removing a liner for an earthquake-resisting pipe jacking method formed by annularly connecting a spacer and a rubbery connecting member by simple structure. SOLUTION: The liner for the earthquake-resisting pipe jacking method has a plurality of spacer bodies 12, in which retaining pieces 12B are extended from both ends in the circumferential direction of block-shaped bodies 12A in thickness corresponding to the wall thickness of a spigot pipe 1 respectively, and rubbery connecting members 13 annularly connecting each spacer body 12 and having elasticity. The liner comprises retaining rings 16 projected from the internal surfaces of the block-shaped bodies 12A in the inside-diametral direction and fender materials 17 bridged extending over both ends in the circumferential direction of the block-shaped bodies 12A.
