SHEET PILE AND CUTOFF METHOD
PROBLEM TO BE SOLVED: To reduce an influence of water pressure brought about by a stream and cut off an opening of an impervious wall by a small number of man-hours.SOLUTION: In a primary cutoff step, a plurality of sheet piles, in which a hole penetrating from the side of one surface to the side of the other surface is provided in a position to be buried in the ground in a state of completion of driving, are erected in such a manner that the hole is positioned under water so that primary cutoff can be performed. In a secondary cutoff step, the plurality of sheet piles erected in the primary cutoff step are driven down in such a manner that the hole is buried into the ground so that secondary cutoff can be performed.
【課題】水流による水圧の影響を低減するとともに少ない工数で遮水壁の開口部を締め切ること。【解決手段】一次締切ステップにおいては、打設が完了した状態において地中に埋まる位置に一方の面側から他方の面側に貫通する穴が設けられた複数の矢板を、当該穴が水中に位置するように建て込んで一次締切を行う。二次締切ステップにおいては、一次締切ステップにおいて建て込まれた複数の矢板を、穴が地中に埋まるように打ち下げて二次締切を行う。【選択図】図４
