- 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)前記既設管の内面下部に沿って当該既設管の全長に亘るように所定の外形寸法を有する第1長尺部材を施工するステップ、
(b)前記ステップ(a)の後、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、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、前記第1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)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または2記載の管路更生工法。
- 前記ステップ(b)の後であって前記ステップ(c)の前に、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第2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をさらに含む、請求項1から3のいずれかに記載の管路更生工法。
- 前記第1長尺部材の外形寸法は、前記第2長尺部材の外形寸法と同じまたは当該第2長尺部材の外形寸法よりも小さい大きさに設定される、請求項4記載の管路更生工法。
