PILE INSTALLATION METHOD
PROBLEM TO BE SOLVED: To provide a pile installation method which can install a pile in a short construction period even if an obstacle exists in the ground.SOLUTION: A pile installation method comprises an obstacle removal process, a bottom-expanded hole excavation process, a reinforcement arrangement process, and a concrete supply process. The obstacle removal process includes a process for inserting at least one casing having a cylindrical shape into the ground until the obstacle in the ground is surrounded by the casing, and a removal process for crushing and removing the obstacle in the ground which is surrounded by the at least one casing, and thereby forming a space part which is surrounded by the at least one casing. The bottom-expanded hole excavation process includes a shaft part excavation process for excavating a lower part lower than the space part in a state that the at least one casing is left in the ground, and forming a shaft part including the space part, and a bottom-expanded part excavation process for excavating the surroundings of a lower end part of the shaft part, and forming a bottom-expanded part.SELECTED DRAWING: Figure 1
【課題】地中障害物が存在していても、短い工期で杭を設置可能な杭設置方法を提供する。【解決手段】杭設置方法は、障害物除去工程と、拡底孔掘削工程と、鉄筋配置工程と、コンクリート供給工程と、を備える。障害物除去工程は、円筒形状を有する少なくとも１つのケーシングを、地中障害物を囲むまで地中に圧入する工程と、少なくとも１つのケーシングによって囲まれた地中障害物を破砕して除去し、これにより少なくとも１つのケーシングによって囲まれた空間部を形成する、除去工程とを含み、拡底孔掘削工程は、地中に少なくとも１つのケーシングが残された状態で、空間部よりも下方を掘削し、空間部を含む軸部を形成する軸部掘削工程と、軸部の下端部周辺を掘削し、拡底部を形成する拡底部掘削工程と、を含む。【選択図】 図１
