ESTABLISHING METHOD OF PILE HOLE FOR DIAMETER EXPANDING PILE
To provide an establishing method of a pile hole for diameter expanding pile, which can efficiently establish a pile hole for an expanded bottom part having a pile hole for an intermediate diameter expanding portion.SOLUTION: An establishing method of a pile hole for diameter expanding pile having a shank-receiving pile hole P1 and a pile hole for intermediate diameter expanding portion P2 comprises : "A" process to establish the shank-receiving pile hole P1 by using a shank-receiving pile hole excavator having an excavation bucket 95 mounted on a kelly bar 20; "B" process to establish the pile hole for intermediate diameter expanding portion P2 by using a pile hole excavator for intermediate diameter expanding portion 100 having a mechanical diameter expanding bucket 80 with a hydraulic mechanism mounted on the kelly bar 20; and "C" process to remove an excavated earth ZD accumulated below the shank-receiving pile hole P1 among the excavated earth generated in the "B" process by the excavation bucket 95.SELECTED DRAWING: Figure 10
【課題】中間拡径部用杭孔を有する拡底部用杭孔を効率的に造成することのできる、拡径杭用杭孔の造成方法を提供する。【解決手段】軸部用杭孔Ｐ１と、中間拡径部用杭孔Ｐ２とを有する拡径杭用杭孔の造成方法であって、ケリーバ２０に掘削バケット９５が取り付けられている軸部用杭孔掘削機を用いて軸部用杭孔Ｐ１を造成するＡ工程、油圧機構を備えた機械式拡径バケット８０がケリーバ２０に取り付けられている、中間拡径部用杭孔掘削機１００を用いて中間拡径部用杭孔Ｐ２を造成するＢ工程、Ｂ工程において発生した掘削土砂のうち、軸部用杭孔Ｐ１の下方に堆積している掘削土砂ＺＤを掘削バケット９５にて排土するＣ工程を有する。【選択図】図１０
