COFFERDAM STRUCTURE USED FOR BRIDGE PIER MAINTENANCE AND REINFORCEMENT WORK
To provide a cofferdam structure used for maintenance and reinforcement work of a bridge pier on a complete water cut-off structure.SOLUTION: A plurality of divided wall members 2 form a cofferdam structure A used for bridge pier maintenance and reinforcement work, which is configured in a cylindrical body surrounding the outer periphery of a bridge pier 1, by being connected in the circumferential direction and the height direction of the bridge pier 1 via a water cut-off member 4. The water cut-off member 4 interposed between the adjacent divided wall members 2 is the cofferdam structure used for bridge pier maintenance and reinforcement work, and is composed of a three-layer structural material with a water-swelling seal 6 attached to the front and back surfaces of a packing 5.SELECTED DRAWING: Figure 2
【課題】完全止水構造の橋脚補修・補強工事に用いる仮締切り構造体を提供すること。【解決手段】複数の分割壁材２が、止水材４を介して橋脚１の周方向および高さ方向に連結されることにより橋脚１の外周を囲む筒状体に構成されている橋脚補修・補強工事に用いる仮締切り構造体Ａであって、隣接する前記分割壁材２間に介在される前記止水材４は、パッキン５の表裏面に水膨張性シール６が付設された三層構造材に構成されている橋脚補修・補強工事に用いる仮締切り構造体。【選択図】図２
