Direction-adjustable multifunctional inner-digging soil extraction pile planting device and construction method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of foundation pit engineering, and in particular relates to an adjustable and multifunctional mid-excavation pile planting device and a construction method thereof. Background technique [0002] The force-bearing body formed by steel pipe combined with cement soil is widely used in the field of construction engineering. The construction method is generally to insert the steel pipe into the soil to a predetermined depth by using a steel pipe insertion machine, and then use a grouting equipment to inject a certain amount of cement slurry into the bottom of the steel pipe. , so that it forms a cement-soil enlarged body in a certain range at the bottom of the steel pipe, and then forms a steel-pipe cement-soil force body with a certain bearing capacity. When the strength of the soil is too high and it is difficult to insert the steel pipe, it is necessary to use a drilling machine to guide the hole to reduce the...
