PROBLEM TO BE SOLVED: To provide a sheet pile driving method which improves self-standing of a sheet pile, which dispenses with injection of a grout material such as mortar and cement for foot protection, and which does not adversely affect an environment.SOLUTION: Hard ground G such as a bedrock is pre-bored at regular intervals by a ground excavator 15. A sheet pile 1 exclusive to pre-boring, the tip part of which is reinforced and which comprises tips 3 and 4 for cutting and crushing the bedrock, is driven to a predetermined depth into an unexcavated hard ground section g between adjacent bored holes 12 and 12 of bored holes 12, which are bored by the pre-boring, by a sheet pile driver 5. After the sheet pile 1 exclusive to the pre-boring is extracted, the sheet pile driver 5 makes a permanent sheet pile 11 driven to a predetermined depth into a pre-boring-specific sheet pile driving trace 6 formed in the unexcavated hard ground section g by the sheet pile 1 exclusive to the pre-boring.
【課題】矢板の自立性を高め、根固め用のモルタルやセメント等のグラウト材の注入が不要で、環境に悪影響を及ぼすことのない矢板打設工法を提供すること。【解決手段】岩盤等の硬質地盤Ｇを地盤掘削機１５によって一定間隔おきにプレボーリングし、プレボーリングによる掘削孔１２の隣り合う掘削孔１２，１２間の未掘削硬質地盤部ｇに、矢板先端部が補強されて岩盤切削破砕用チップ３，４を備えた先行堀り専用矢板１を、矢板打設機５によって所定深度まで打設し、先行堀り専用矢板１を引き抜いた後、先行堀り専用矢板１によって前記未掘削硬質地盤部ｇに形成された先行堀り専用矢板打設痕６に本矢板１１を矢板打設機５によって所定深度まで打設する。【選択図】図３
