WATER CUT-OFF METHOD FOR COFFERDAM STRUCTURE USED IN BRIDGE PIER REPAIR/REINFORCEMENT WORK
PROBLEM TO BE SOLVED: To provide a water cut-off method for a cofferdam structure used in bridge pier repair/reinforcement work that readily realizes a complete water cut-off state that prevents water infiltration into the cofferdam structure.SOLUTION: A cofferdam structure 2 is constructed to surround an outer periphery of a bridge pier 1, the cofferdam structure having a through-hole part 3, through which the bridge pier 1 penetrates and is disposed, formed at a bottom part at a non-submerged location in an upper part of the bridge pier 1. The cofferdam structure 2 is submerged underwater below the bridge and a gap 4 between the through-hole part 3 and the bridge pier 1 is closed with concrete leakage prevention means 5. Then, concrete 6 is filled in the gap 4, and the gap 4 is sealed and water is cut-off as the concrete 6 hardens.SELECTED DRAWING: Figure 1
【課題】仮締切り構造体内に水が浸入しない完全な止水状態を簡易に実現できる橋脚補修・補強工事に用いる仮締切り構造体の止水工法を提供すること。【解決手段】橋脚１の上方の非水没箇所で、底部に橋脚１を貫通配設する貫通孔部３が設けられ橋脚１の外周を囲むように設置される仮締切り構造体２を構築し、この仮締切り構造体２を橋下の水中に降下させ、前記貫通孔部３と前記橋脚１との間の間隙部４をコンクリート漏止手段５で塞いでからこの間隙部４にコンクリート６を充填し、このコンクリート６の硬化により前記間隙部４を密閉して止水する。【選択図】図１
