To provide a method for restoring an existing bridge in a state of securing a flow under the bridge.SOLUTION: Divided support frames that penetrate a flow passage space are installed between abutments or the like. The divided support frames are formed to be shorter than the width of a bridge, and are sequentially installed at the lower part of the bridge and then integrated to form a support frame group. A cutoff wall is formed in parallel with the central axis of the bridge so as to shield at least the vertical surface on the valley side of the bridge. This is achieved by filling the inside of the space enclosed by the upper surface of the cutoff wall and the support frame group, the lower surface of the existing bridge, and the inner surface of the abutment or the like.SELECTED DRAWING: Figure 1
【課題】橋梁下の流れを確保した状態で、既設の橋梁を再生する方法を提供する。【解決手段】橋台と橋台などの間に、内部に流路空間を貫通した分割支持枠を設置する。この分割支持枠は橋梁の幅よりも短く形成し、橋梁の下部に順次設置した後に一体化して支持枠群を形成する。橋梁の少なくとも谷側の鉛直面を遮蔽する状態で橋梁の中心軸と平行に遮断壁を形成する。この遮断壁と支持枠群の上面と、既設の橋梁の下面と、橋台等の内側面で包囲した空間の内部に固結材を充填して行う。【選択図】図１
