WATER STOP STRUCTURE OF SHEET PILE JOINT, METHOD OF DRIVING STEEL SHEET PILE AND STEEL SHEET PILE WATER IMPERMEABLE WALL
To effectively prevent ground components from invading a fitting groove of a joint, and to control an increase in the construction cost of an underground wall and an impermeable wall and the complication of a construction work, when driving a steel sheet pile in the ground.SOLUTION: By filling a steel sheet pile, which has been driven in advance, and fitting grooves S and X of a joint portion with a water blocking material to make it in a closed state, a ground components such as sediment and pebbles that impede the performance of water blocking is prevented from invading the fitting groove of the joint portion. In a next following steel sheet pile driving process, the joint portion is fitted and completed according to the movement in the direction of driving the sheet pile while gradually cutting off or breaking off the water blocking material with the joints E, F, G, etc. at a tip of a hook portion. As a result, it is possible to fill a gap of the fitting portion with a water blocking material (such as a water expansive water blocking material) that does not contain foreign matter, and it is a water blocking material that fills the space that can always be made in the fitting portion even with the change of shape, and sufficient water blocking of the sheet joint is obtained.SELECTED DRAWING: Figure 7
【課題】鋼矢板を地盤中に打設する際に、継手部の嵌入溝に地盤構成物が侵入する事を効果的に防止し、かつ地下壁体や遮水壁の構築コストの増加及び構築作業の煩雑化を制御する。【解決手段】先行して打設される鋼矢板、継手部の嵌入溝Ｓ、Ｘを止水材で満たし閉塞状態とする事により、止水性能を阻害する土砂や小石等の地盤構成物が継手部の嵌入溝へ侵入する事を防ぐ。次の後続鋼矢板打設行程で、継手、鈎状部先端の爪Ｅ、Ｆ、Ｇ等で、前記の止水材を徐々に切取り剥離させ又は砕きながら矢板打設方向への移動に従って、継手部が嵌合し完成する。この結果、異物の混入していない止水材（水膨張性止水材等）で継手嵌合部の隙間を埋めることになる、形が変わっても嵌合部に必ずできる空間を満たした止水材で、矢板継手部の十分な止水が得られる。【選択図】図７
