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、
(a)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、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み、前記既設管内に前記螺旋管を施工するステップ、
(b)前記ステップ(a)の後、前記既設管の内面上部と前記螺旋管の外面上部との間に、所定の外形寸法を有する長尺部材を前記既設管の全長に亘るように施工するステップ、および
(c)前記ステップ(b)の後、前記既設管の内面と前記螺旋管の外面との間に充填材を充填するステップを含む、管路更生工法。 - 前記ステップ(b)では、前記長尺部材として線状体を用いる、請求項1記載の管路更生工法。
- 前記ステップ(a)の前に、前記既設管の内面上部に沿って当該既設管の全長に亘るように引込み線を施工するステップをさらに含み、
前記ステップ(b)では、前記引込み線を用いて前記長尺部材を前記既設管内に引き込むことで、前記既設管の内面上部と前記螺旋管の外面上部との間に前記長尺部材を施工する、請求項1または2記載の管路更生工法。 - 前記ステップ(a)では、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ることで、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する、請求項1から3のいずれかに記載の管路更生工法。
