To provide a repair method for a canal which can easily and speedily define a canal repair area in the canal without shutting off running water using a canal partition plate, allowing the fewer number of relocation times as the repair area per work unit is large, and being excellent in work efficiency as an upper part is open.SOLUTION: A repair method for a canal comprises steps of: arranging in line water canal partition plates 1 on a water canal floor 53 along a longitudinal direction of the canal in a condition where an existing water canal 51 is divided into two sections in a width direction; holding the water canal partition plates 1 in an erected condition through constructing partition plate supporting bodies 5 between the water canal partition plates 1 and one side wall 54; attaching respectively leakage prevention panels 3 which have leakage prevention seal material 3C abutting the water canal floor 53, on sides of the water canal partition plates 1; and exposing the water canal floor 53 and the one side wall 54 in a canal repair area Z by defining the canal repair area Z in the existing water canal 51 using the water canal floor 53, the one side wall 54 and the water canal partition plates 1 to shut off water with a cut-off body 11 arranged on an upper stream end side of the canal repair area Z.SELECTED DRAWING: Figure 2
【課題】水路仕切板を用いて流水を止めずに水路に水路補修域を容易に、速やかに画成し、１作業単位の補修面積が広いので移動回数が少なく、また上方が開放しているので作業効率に優れている水路の補修工法を提供する。【解決手段】既設水路５１を幅方向に二分する状態で水路の長手方向に沿って水路床５３上に水路仕切板１を列設し、水路仕切板１と側壁５４の一方との間に仕切板支持体５を架設して水路仕切板１を起立状態に保持する。水路床５３に接する漏水防止シール材３Ｃを有する漏水防止パネル３を水路仕切板１の側面に添設する。水路床５３、一側側壁５４及び水路仕切板１によって既設水路５１内に水路補修域Ｚを画成し、路補修域Ｚの上流端側に止水体１１を配置して遮水することにより、水路補修域Ｚの水路床５３及び側壁５４を露出させる。【選択図】図２
