Claims (4)
- 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む、管路更生工法。 - 前記螺旋管の製管開始時には、少なくとも前記ライニング部材の隣り合う側縁部どうしが連結可能となる位置まで当該ライニング部材を螺旋状に巻き回して当該ライニング部材の位置決めを行った後、前記連結部材による前記ライニング部材の隣り合う側縁部どうしの連結を開始する、請求項1記載の管路更生工法。
- 前記螺旋管の製管開始時における前記ライニング部材の位置決めは、当該ライニング部材の巻き回しを一旦停止した状態で行う、請求項2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から3のいずれかに記載の管路更生工法。
