Summary:The utility model relates to the technical field of civil engineering piling equipment accessory devices. The utility model relates to a pile, in particular to a large-diameter steel pipe pile. The steel pipe pile can be rapidly sunk, then the pile end of the steel pipe pile is opened after pile sinking to form the effect of a closed pipe pile, the pile end and a pile body are connected into a whole, and therefore the pile sinking construction efficiency is guaranteed, the pile foundation bearing capacity is improved, rapid and low-cost pile sinking of the large-diameter steel pipe pile is reduced, and the difficulty of a large soil plug effect coefficient is lowered; the device comprises a tubular pile, a long shaft, a fixed shaft, a left blade, a right blade, two pull rods, two rotatingshafts and a pull rope, a penetrating hole penetrates through the bottom end of the pipe pile, the front end and the rear end of the long shaft are connected with the bottom areas of the front end andthe rear end of the penet
