Long spiral drilling machine used for forming long spiral broaching pile and pile forming method
The invention discloses a long spiral drilling machine used for forming a long spiral broaching pile and a pile forming method and relates to a rock and soil layer drilling device and a pile forming method. According to the long spiral drilling machine for forming the long spiral broaching pile and the pile forming method, the structure is simple, cost is low, and the pile forming quality is good. The long spiral drilling machine used for forming the long spiral broaching pile comprises a first power head, a drill rod and a drill bit. The output end of the first power head is in transmission connection with the drill rod, the drill rod is externally provided with a spiral blade, the drill bit is provided with a concrete valve, and the drill rod is connected with a concrete pump station. The long spiral drilling machine used for forming a long spiral broaching pile further comprises a drill cylinder and a second power head. The drill cylinder and the drill rod are coaxially arranged. The inner diameter of the drill cylinder is slightly larger than the outer diameter of the spiral blade on the outer portion of the drill rod. A through hole is formed in the cylinder wall of the bottom of the drill cylinder, the wall of the through hole is provided with a hinge shaft parallel to the axis of the drill cylinder, a broaching valve is connected to the hinge shaft, the shape of the broaching valve is the same with that of the through hole, the output end of the second power head is connected with the drill cylinder, and the second power head is installed on a mask of the long spiral drilling machine.
