The invention discloses a direction-adjustable multifunctional inner-digging soil extraction
pile planting device. The device comprises an
airplane head, a power head, a soil storage box, a
pile splicing device, a steel
pipe and precast
pile, a front support, an auxiliary support, a mast, a long spiral soil extraction
drill, a crawler-type main engine, a rear support, a balance weight, a main
winch, an adjustable middle support, a cab and an
angle gauge. The
airplane head is mounted at the top end of the mast and is connected with the crawler-type main engine through the main
winch. The mast is connected with the crawler-type main engine through the adjustable middle support, and the mast and the adjustable middle support are arranged in an angle manner. The power head is mounted on the mast and is connected with a
pulley at the top end of the
airplane head through a steel
wire rope. The steel
wire rope drives the power head to move on a sliding rail of the mast. The soil storage box is mounted below the power head through an oil cylinder. The long spiral soil extraction
drill is connected with the power head. The steel
pipe and precast pile is connected with the soil storage box through the pile splicing device. The direction-adjustable multifunctional inner-digging soil extraction pile planting device has the advantages that construction is simple and convenient, the cost islow, the pile body construction length is large, and the effect is fast; no soil
extrusion effect exists, and no influence is generated on surroundings; and direction-adjustable construction is achieved, and the application range is wide.
