Spiral type tube-sinking cast-in-situ pile
The invention discloses a spiral type tube-sinking cast-in-situ pile which comprise a pile body and a pile tip. The uppermost end of the pile body is provided with a pile body lap joint ring. Coherent threads are disposed on the surfaces of the pile body and the pile tip. The pile body is in rotation lap joint fastener connection with the pile tip through a pipe body lap joint fastener and a pile tip lap joint fastener. The spiral type tube-sinking cast-in-situ pile has the advantages that the pile can be fast screwed into a hard soil layer and a dense sand layer; the threads are distributed on the surface of the pipe, sinking and pulling out depth during screwing in and screwing out can be well controlled, and construction is facilitated; thirdly, pile side friction can be effectively enhanced, pile bearing capacity and uplift resistance can be increased, and project cost can be reduced; the pile tip is made of cast iron, so that abrasion of the pile tip during screwing in can be reduced.
