RENOVATION STRUCTURE FOR EXISTING COVERED CONDUIT
To provide a renovation structure for an existing covered conduit preventing a renovation pipe from floating up through buoyancy by residence of water having intruded around the renovation pipe of the existing covered conduit with locations where water intrudes from a surrounding ground through a wall constituted with masonry and concrete and the like, and preventing outflow of the surrounding ground causing depression accidents.SOLUTION: A renovation structure for an existing covered conduit is provided with: a renovation pipe 2 forming a conduit therein; a filling material 3 filled and cured between the renovation pipe 2 and an existing covered conduit 1; a surface-shaped material 4 placed on a boundary between the filling material 3 and a side wall 11 of the existing covered conduit 1; and a water guide pipe 5 provided on a boundary between the surface-shaped material 4 and the existing covered conduit 1 in a pipe axial direction of the renovation pipe 2 to which water intruding from a surrounding ground through the side wall 11 of the existing conduit 1 is introduced.SELECTED DRAWING: Figure 1
【課題】石積やコンクリート等で構成された壁部を通して周囲の地盤から水が浸入する箇所が存在する既設暗渠の更生管の周囲に浸入した水が滞留し、更生管に浮力がかかって浮き上がったり、周囲の地盤が流出して陥没事故を起こしたりすることのない既設暗渠の更生構造を提供すること。【解決手段】内部に水路を形成する更生管２と、更生管２と既設暗渠１との間に充填、硬化されてなる充填材３と、充填材３と既設暗渠１の側壁部１１との境界に設けた面状部材４と、面状部材４と既設暗渠１との境界に、更生管２の管軸方向に設けた、既設暗渠１の側壁部１１を通して周囲の地盤から浸入した水が導入される導水管５とを備える。【選択図】図１
