FLOOR SLAB CONSTRUCTION METHOD AND FLOOR SLAB UNIT FOR COFFERDAM STRUCTURE
To provide a floor slab construction method for cofferdam structure and a floor slab unit used in the construction method which can act as a cutoff for a cofferdam structure without using underwater concrete.SOLUTION: A construction method is a method for constructing a floor slab 1 in a tubular cofferdam structure constructed around a bridge pier, in which: the floor slab 1 is composed of a plurality of floor slab units 2, 2, ... and a plurality of support legs 3 for supporting the floor slab 1 are arranged at prescribed intervals on the outer periphery of a pier foundation Pf. The floor slab 1 is formed by connecting each floor slab unit 2 and the bridge pier P in a separable manner while interposing cutoff members 4 between the adjacent floor slab units 2, 2 and between the floor slab unit 2 adjacent to the bridge pier and the bridge pier P, respectively. The floor slab 1 thus formed is supported by the support legs 3.SELECTED DRAWING: Figure 1
【課題】水中コンクリートを使用することなく仮締切構造体の止水を行える仮締切構造体の床版の施工方法と、当該工法に使用する床版ユニットを提供する。【解決手段】橋脚周りに構築される筒状の仮締切構造体における床版１の施工方法であって、床版１を、升目状に分割してなる複数の床版ユニット２，２，…で構成し、橋脚基礎Ｐｆの外周に、床版１を支持する支持脚３を所定間隔をあけて複数配置し、隣接する床版ユニット２，２同士の間および橋脚に隣接する床版ユニット２と橋脚Ｐとの間のそれぞれに止水部材４を介在させつつ各床版ユニット２と橋脚Ｐとを分離可能に連結して床版１を形成し、形成された床版１を支持脚３によって支持する。【選択図】 図１
