NCアミブルー(非円形管)

In Gunma prefecture, for the first time a Non Circular (NC) pipe was installed in a bridge repair project. The egg shape pipe fitted ideally the triangular section of the bridge, keeping the drainage in operation and the installation was carried out quickly and easily.

群馬県、橋梁補修工事で非円形管が初めて利用された。逆三角形型の橋の断面の中に水路を維持するために卵形管は理想的であり、設置も容易で工事は素早く完成した。
