CONSTRUCTION METHOD FOR STEEL PIPE PILE AND STEEL PIPE PILE
To provide a construction method for a steel pipe pile and a steel pipe pile which reduce labor and a cost for working due to a configuration that can be simply worked, and can eliminate disturbance of a lower ground.SOLUTION: In a construction method for a steel pipe pile 1 installed in the ground G, the steel pipe pile 1 includes a pile body 2 composed of a steel pipe, and a plate-like expansion blade 3 that blocks a lower end 2a of the pile body 2 by a plate surface perpendicular to a pile axis O direction, is expanded by an outer peripheral surface 2b of the pile body 2 when viewed from the pile axis O direction, and has at least one corner part 3c formed on a plate outer peripheral edge, and the construction method includes a step of applying a pressure to the lower side of the steel pipe pile 1, and press fitting the expansion blade 3 to the ground G in a state where a lower surface 3b of the expansion blade 3 is brought into direct contact with the ground G, and a step of rotating the steel pipe pile 1, and excavating the ground G.SELECTED DRAWING: Figure 1
【課題】簡単に加工できる構成とすることで、加工にかかる手間とコストを低減するとともに、下部地盤の乱れを無くすことができる鋼管杭の施工方法および鋼管杭を提供する。【解決手段】地盤Ｇ中に設置される鋼管杭１の施工方法において、鋼管杭１は、鋼管からなる杭本体２と、杭本体２の下端２ａを杭軸Ｏ方向に直交する板面によって閉塞するとともに、杭軸Ｏ方向から見て杭本体２の外周面２ｂより拡大され、少なくとも１つの角部３ｃが板外周縁に形成された平板状の拡大翼３と、を備え、拡大翼３の下面３ｂを地盤Ｇに直接接触させた状態で、鋼管杭１に対して下方に圧力を与えて拡大翼３を地盤Ｇに圧入させる工程と、鋼管杭１を回転させて地盤Ｇを掘削する工程と、を有する構成とした。【選択図】図１
