BELT-LIKE MEMBER FOR EXISTING PIPE REHABILITATION

To smooth an outer circumferential surface of a rehabilitation pipe which is manufactured into a pipe as much as possible to suppress ground surface cave-ins while preventing pipe manufacturing of the rehabilitation pipe from being hindered.SOLUTION: A belt-like member 10 for existing pipe rehabilitation comprises: a bottom plate part 11 that constitutes a pipe wall part 9a on an inner circumferential side of a rehabilitation pipe 9; a lid plate part 12 that constitutes a pipe wall part 9b on an outer circumferential side of the rehabilitation pipe 9; a vertical plate part 15 that connects the bottom plate part 11 and the lid plate part 12; first engaging parts 13 and 16 on one end part in a width direction; and second engaging parts 14 and 17 on the other end part. The lid plate part 12 extends toward one end side in the width direction with respect to the bottom plate part 11, and the other end side recedes. The first engaging parts 13 and 16 are covered by the one end part 12f in the width direction of the lid plate part 12 from the outer circumferential side, or provided on an inner circumferential side surface of the one end part 12f in the width direction of the lid plate part 12.SELECTED DRAWING: Figure 2 【課題】更生管の製管に支障を来たさないようにしながら、製管された更生管の外周面をなるべく平滑にして、地表の陥没を抑制する。【解決手段】既設管更生用の帯状部材１０は、更生管９の内周側の管壁部９ａを構成する底板部１１と、更生管９の外周側の管壁部９ｂを構成する蓋板部１２と、底板部１１と蓋板部１２を連ねる縦板部１５と、幅方向の一端部の第１嵌合部１３，１６と、他端部の第２嵌合部１４，１７を備えている。蓋板部１２は、底板部１１に対して幅方向の一端側へ延び出て他端側が引っ込んでいる。第１嵌合部１３，１６は、蓋板部１２の幅方向の一端部１２ｆによって外周側から覆われているか、又は蓋板部１２の幅方向の一端部１２ｆの内周側面に設けられている。【選択図】図２
