TEMPORARY CUT-OFF METHOD, TEMPORARY CUT-OFF STRUCTURE, SUPPORTING, SUPPORTING UNIT
PROBLEM TO BE SOLVED: To provide a temporary cut-off method that contributes to improvement of workability during construction of a structure in water area and quality of the structure.SOLUTION: A water area 3 is cut off by a well-like steel pipe sheet pile 4, then the inside of the well formed of the steel pipe sheet pile 4 is bored underwater. After a truss supporting 1 is installed in the well and dried up, a structure is constructed. The truss supporting 1 has an annular flat surface in substantially hollow square shape along the inner periphery of the well formed of the steel pipe sheet pile 4, an opening 15 at its central part, and a truss structure in flat. The truss supporting 1 is installed in vertically plural steps. The truss supporting 1 formed of upper and lower two steps is vertically connected by the truss structure.SELECTED DRAWING: Figure 4
【課題】水域の構造物の構築時の施工性や構造物の品質の向上に寄与する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３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１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１は、鋼管矢板４による井筒の内周に沿った略ロの字状の環状平面を有し、中央部が開口１５となっており、且つ平面においてトラス構造を有する。トラス支保工１は上下複数段に設置され、上下２段のトラス支保工１は、トラス構造によって上下に連結される。【選択図】図４
