Deviation correction device for tube-sinking cast-in-situ pile and use method thereof

Abstract

The invention discloses a deviation correction device for a tube-sinking cast-in-situ pile and a use method thereof. The deviation correction device for the tube-sinking cast-in-situ pile comprises adouble-acting steam hammer, wherein the double-acting steam hammer is arranged at the top of a sinking tube, a plurality of high pressure fans are evenly arranged on the periphery of the sinking tube,each high pressure fan is connected with an air guiding main pipe and a plurality of air guiding branch pipes, the air guiding branch pipes are evenly arranged on the circumference of the outer sideof the inner wall of the sinking tube, a plurality of expansible air cushions are evenly arranged on the circumference of the outer side of the outer wall of the sinking tube, and make contact with asoil body around the sinking tube, the expansible air cushions communicate with the corresponding air guiding branch pipes, an air pressure device is arranged at the lower end of each air guiding branch pipe, and the air pressure devices are connected with a prefabricated pile tip through lifting sleeves. The deviation correction device for the tube-sinking cast-in-situ pile arranges the expansible air cushions on the outer wall of the sinking tube, drives the expansible air cushions to expand through high pressure airstream so as to enable the expansible air cushions to act on the soil body around the sinking tube, enables the soil body to generate counter-acting force on the sinking tube, pushes the sinking tube to move towards a predetermined direction, and realizes deviation correctionfor the sinking tube; and drives the telescopic sleeves to stretch and contract through the air pressure devices, and realizes adjustment for angles of the prefabricated pile tip.

Description

technical field [0001] The invention relates to the technical field of bridge pile foundation construction, in particular to a deviation correcting device for cast-in-place piles with immersed tubes and an application method thereof. Background technique [0002] Pile is a column-shaped component set in the foundation. According to different purposes, there are different classifications of pile foundations; different types of pile foundations have their own characteristics in their own structure and pile-soil interaction performance. Among them, the pile hammer is used to drive the pile tube and the prefabricated pile tip into the soil, and its action mechanism on the soil is similar to that of the closed steel pipe pile by the hammering method. While pulling out the pipe, vibrating, pouring concrete, and forming while pulling out the pipe; in the process of pulling out the pipe, due to the continuous low hammer and dense impact on the pile pipe, the steel pipe is continuous...
