- ライニング部材を螺旋状に巻き回して製管した螺旋管を用いて既設管を更生する管路更生工法であって、
マンホール内で前記ライニング部材を螺旋状に巻き回すと共に、螺旋状に巻き回した前記ライニング部材の外面側から連結部材を取り付けて当該ライニング部材の隣り合う側縁部どうしを連結して前記螺旋管を形成しながら、形成した前記螺旋管を前記マンホール内から前記既設管内に順次送り込んでいく工程を含み、
前記ライニング部材は、螺旋状に巻き回したときの外面側の両側部のそれぞれに形成される第1係合部を備え、
前記連結部材は、前記第1係合部のそれぞれと係合される第2係合部を備え、
前記第1係合部は、前記ライニング部材の長手方向に延びる第1突条と、前記第1突条の一方側面の先端部に形成される第1係止片とを有し、
前記第2係合部は、前記連結部材の長手方向に延びる第2突条と、前記第2突条の一方側面に形成され、前記第1係止片と係合される第2係止片とを有する、管路更生工法。 - 前記連結部材によって前記ライニング部材の隣り合う側縁部どうしを連結して前記螺旋管を形成した状態において、前記連結部材の最外部は、前記螺旋管の径方向における前記ライニング部材の最外部よりも外側に位置する、請求項1記載の管路更生工法。
- 前記ライニング部材を螺旋状に巻き回すときには、前記ライニング部材の側縁どうしを突き合わせる、請求項1または2記載の管路更生工法。
