METHOD OF RENOVATING CIRCULAR WATER CONDUIT
To provide a method of renovating a circular water conduit by which, in the renovation of the circular water conduit where defects have occurred, construction can be performed with high construction efficiency and in a short time, the circular water conduit after renovation has the same strength and shape as an existing part so that it can have sufficient strength against long-term use as the circular water conduit.SOLUTION: The method of renovating the circular water conduit comprises: removing an upper part of an existing circular water conduit, where the defects have occurred, over a longitudinal direction so as to have at least a width of a water conduit part to provide a hollow part, installing a cylindrical frame having a circular cross section having a size along a curved surface of the water conduit part on the water conduit part remaining below the hollow part, providing a concrete layer in the hollow part which is to be the upper part of the frame, and then, removing the frame.SELECTED DRAWING: Figure 2
【課題】欠損が生じた円形水路の改修において、施工効率が良く短時間で施工でき、改修後の円形水路が既存部分と同様の強度や形状を有して、円形水路としての長期の使用に十分耐えうるものである円形水路の改修工法を提供すること。【解決手段】欠損が生じた既存の円形水路の上方部を少なくとも水路部の幅を有して長手方向にわたって除去して空洞部を設け、前記空洞部の下方に残った水路部上に該水路部の湾曲面に沿った大きさの断面円形状の円筒形状の枠を設置し、前記枠の上方部となる空洞部にコンクリート層を設け、その後前記枠を撤去する、円形水路の改修工法である。【選択図】図２
