INSTALLATION METHOD FOR COFFERDAM STRUCTURE USED FOR BRIDGE PIER REPAIR AND STRENGTHENING WORK
To provide an installation method for cofferdam structure used for bridge pier repair and strengthening work that can efficiently construct a cofferdam structure on a water area.SOLUTION: After installing a lower side cofferdam structure 2a in a water area, a work scaffold 4 is lowered to the upper position of the lower side cofferdam structure 2a installed in the water area. The lowered work scaffold 4 is used as a platform to construct an upper cofferdam structure 2b, which is the upper side of a cofferdam structure 2, directly on the lower side cofferdam structure 2a.SELECTED DRAWING: Figure 9
【課題】水域上に効率良く仮締切り構造体を構築することができる橋脚補修・補強工事に用いる仮締切り構造体の設置工法を提供することを目的とする。【解決手段】下部側仮締切り構造体２ａを水域中に設置した後、作業用足場４をこの水域中に設置した下部側仮締切り構造体２ａの上部位置まで降下させ、この降下させた作業用足場４を足場にして下部側仮締切り構造体２ａ上に仮締切り構造体２の上部側となる上部側仮締切り構造体２ｂを直接構築する。【選択図】図９
