Summary:To provide a water cut-off structure with reduced gaps between sandbags and improved water cut-off property.SOLUTION: A water cut-off structure 1 mainly comprises: a water proof sheet material 2 laid on an outdoor floor face 83; sandbags 4 installed above the sheet material 2; and hard jigs 3a and 3b installed on an upper face of the sheet material 2 and between the sheet material 2 and the sandbags 4. The jigs 3 are installed across a region A1 to be contacted that is a region where the sandbag 4 is in contact with the sheet material 2 when there is no jig 3 and a region A2 not to be contacted that is a place of a gap 86 between the sandbag 4 and the sheet material 2. Thus, load of the sandbag 4 is added to the sheet material 2 uniformly in a wider region, to improve water proof property.SELECTED DRAWING: Figure 2 【課題】 土のうの隙間を減少させ止水性を向上させた止水構造体を提供する。【解決手段】 止水構造体１は、屋外側の床面８３に敷設される防水性のシート材２と、シート材２の上方に設置される土のう４と、シート材２の上面であって、シート材２と土のう４との間に設置される硬質の治具３ａ、３ｂとから主に構成されている。又、治具３は、治具３が無い場合には土のう４がシート材２に接触していた領域である予定接触領域Ａ１及び土のう４とシート材２との隙間８６の箇所であった非予定接触領域Ａ２に亘って設置されている。このように構成することで、シート材２に対し、土のう４の荷重がより広い領域で均一化して加わるため、止水性能が向上する。【選択図】 図２
