TEMPORARY COFFERDAM METHOD, TEMPORARY COFFERDAM STRUCTURE
To provide a temporary cofferdam method or the like that is easy to construct.SOLUTION: After a water area is closed off by a well-shaped steel pipe sheet pile 4, the inside of the well by the steel pipe sheet pile 4 is excavated underwater. After that, truss supports 1a and 1b are installed inside the well and after drying up, a structure is constructed. The truss supports 1a and 1b have a truss structure in a plane. The truss supports 1a are placed along one pair of opposing sides of the well and the truss supports 1b are placed along another pair of opposing sides of the well. As a result, an opening 100 is formed inside the truss supports 1a and 1b at the center of the well.SELECTED DRAWING: Figure 4
【課題】施工の容易な仮締切方法等を提供する。【解決手段】井筒状の鋼管矢板４により水域を締切った後、鋼管矢板４による井筒の内部を水中掘削する。その後、井筒内部にトラス支保工１ａ、１ｂを設置してドライアップした後構造物の構築を行う。トラス支保工１ａ、１ｂは平面においてトラス構造を有し、トラス支保工１ａは、井筒の対向する位置にある一組の辺に沿って配置され、トラス支保工１ｂは、井筒の対向する位置にある別の一組の辺に沿って配置される。これにより、井筒の中央部でトラス支保工１ａ、１ｂの内側に開口１００が形成される。【選択図】図４
