JOINT PART WATER CUT-OFF METHOD OF STEEL SHEET PILE
To provide a joint part water cut-off method of a steel sheet pile which can cut off a gap of a joint part of a steel sheet pile to which water flows with a simple method, and can perform usual demolition work of a steel sheet pile without hindering demolition of a steel sheet pile.SOLUTION: A method includes: mounting a weight 2 to a lower part of a thin cut-off film 1 having flexibility, adhesion and water tightness; suspending the weight 2 mounted on the lower part of the cut-off film 1 below the surface of the water along a gap 13 of a joint part 12 from above the joint part 12 of a steel sheet pile 11 having the gap 13 to which water on a side facing a water area of an external side b flows; bringing the cut-off film 1 suspended below the surface of the water from above into close contact with the gap 13 of the joint part 12 on the side facing the water area on the external side b using a water pressure flowing toward the gap 13 of the joint part 12; and cutting off water flowing from the water area on the external side b by the cut-off film 1.SELECTED DRAWING: Figure 1
【課題】水が流入する鋼矢板の継手部の隙間を簡単な方法で止水することができ、しかも鋼矢板の解体にも支障がなく、通常の鋼矢板の解体作業を行うことのできる鋼矢板の継手部止水方法を提供する。【解決手段】薄くて、柔軟性、密着性及び水密性を有する止水フィルム１の下部に錘２を取り付け、外部側ｂの水域に臨む側の水が流入する隙間１３を有する鋼矢板１１の継手部１２の上方から、止水フィルム１の下部に取り付けた錘２を継手部１２の隙間１３に沿って水面下に垂れ下げて、継手部１２の隙間１３に向けて流入する水圧を利用して、外部側ｂの水域に臨む側の継手部１２の隙間１３に上方から水面下に垂れ下げた止水フィルム１を密着させて、止水フィルム１により外部側ｂの水域から流入する水を止める方法よりなる。【選択図】 図１
