A new type of power traction earth taking system and its application method

Abstract

The invention relates to a novel power-traction soil-taking system and a using method thereof. The novel power-traction soil-taking system comprises a power supplying system, a traction system and a soil-taking and soil-discharging system, wherein the soil-taking and soil-discharging system comprises a U-shaped hanging ring, a soil-storing sleeve, U-shaped fixing hanging rings welded on the outer side wall of an opening at the upper end of the soil-storing sleeve, edge feet welded on the outer side wall of an opening at the bottom of the soil-storing sleeve; a limiting rod welded on the inner side wall of the opening at the bottom of the soil-storing sleeve, a valve rotating shaft welded on the cylinder wall, at a distance of 30 cm from an opening in the bottom, of the sleeve wall of the soil-storing sleeve, and a rotary valve welded on the valve rotating shaft and rotate through the valve rotating shaft to achieve closing and opening functions; the U-shaped hanging ring is connected with the U-shaped fixing hanging rings through a rope and is connected with a power traction rope. The soil-taking and soil-discharging system achieves an inserting soil-taking function through the edge feet, is connected with the traction system through a connecting pulley B, and achieves a soil-discharging function through the rotary valve, so that the technical difficulty that soil in a PHC (prestressed high-strength concrete) tubular pile is difficult to discharge due to a small caliber is effectively overcome, the cost is reduced and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of earth-taking devices in foundation construction engineering, and particularly provides a novel power traction earth-taking system and a use method. Background technique [0002] Currently international and domestic railways, highways, municipal administration, water conservancy, hydropower, housing construction, wharfs, ports and airports, etc. have PHC pipe piles or similar foundation constructions that need to take soil from holes, relying solely on water impact or manual excavation. , slow speed, low work efficiency, and difficult to effectively guarantee the project duration. Contents of the invention [0003] In order to solve the technical problems existing in the known technology, the present invention provides a novel power traction soil-taking system and a using method capable of taking soil in pipe pile foundation holes at a high speed, with high work efficiency and shortened construction period.
