EXCAVATION METHOD OF PILE HOLE, PILE CONSTRUCTION METHOD, AND PILE
To provide an excavation method of a pile hole, a pile construction method, and a pile which can suppress diffusion of a contaminant by an easy and inexpensive method.SOLUTION: An excavation method of a pile hole includes an adjustment step of adjusting an excavation liquid containing bentonite or a hardly water-permeable material according to the ground, and an excavation step of excavating a pile hole in the ground by using an excavation liquid adjusted by the adjustment step. The adjustment step adjusts the excavation liquid so that a coefficient permeability of a mixture of excavation soil and the excavation liquid in the pile hole is smaller than a coefficient permeability of a permeable layer which is brought into contact with the pile hole and is not contaminated.SELECTED DRAWING: Figure 2
【課題】容易且つ安価な方法で汚染物質の拡散を抑制することができる杭穴の掘削方法、杭の施工方法、及び杭を提供すること。【解決手段】杭穴の掘削方法は、地盤に合わせてベントナイト又は難透水性材料を含む掘削液を調整する調整工程と、調整工程で調整した掘削液を用いて地盤に杭穴を掘削する掘削工程と、を有する。調整工程では、杭穴内の掘削土と掘削液の混合物が、杭穴に接する汚染されていない透水層の透水係数より小さい透水係数となるように、掘削液を調整する。【選択図】 図２
