AUGER COMBINEDLY-USING STEEL SHEET PILE PRESS-IN METHOD

YASUOKA HIDEKI / IGAKI SANEHIRO

PROBLEM TO BE SOLVED: To provide an auger combinedly-using steel sheet pile press-in method for pressing in a steel sheet pile of various joint pitches by combinedly using simultaneous excavation by an auger when pressing in a steel sheet pile, by using the same steel sheet pile press-in pull-out machine.SOLUTION: By using the same steel sheet pile press-in pull-out machine 50, a U-shaped steel sheet pile 1 different in a joint pitch is continuously pressed in by mutually meshing a joint, by combinedly using simultaneous excavation by an auger 25 of using an auger casing 2 different in a diameter in response to the joint pitch of the steel sheet pile 1.SELECTED DRAWING: Figure 2

【課題】同一の鋼矢板圧入引抜機を使用して、多様な継手ピッチの鋼矢板を、鋼矢板圧入時におけるオーガによる同時掘削を併用して圧入するオーガ併用鋼矢板圧入工法を提供する。【解決手段】同一の鋼矢板圧入引抜機５０を使用して、継手ピッチが異なるＵ型の鋼矢板１を、該鋼矢板１の継手ピッチに応じて直径が異なるオーガケーシング２を使用するオーガ２５による同時掘削を併用して、相互に継手を噛合させて連続して圧入する。【選択図】図２
