Quick positioning and verticality-adjusting device for large-diameter steel-pipe upright column pile and construction method

Abstract

The invention provides a quick positioning and verticality-adjusting device for a large-diameter steel-pipe upright column pile and a construction method. The device comprises a positioning support and a verticality-adjusting bracket, wherein the positioning support comprises a square outer frame; limiting steel plates are arranged on the middle inner sides of four side frames of the outer frame; the verticality-adjusting bracket comprises a lining pile casing; the steel-pipe upright column pile is arranged in the lining pile casing; eight verticality-adjusting support legs are uniformly distributed around the lining pile casing; the verticality-adjusting support legs are clamped in the limiting steel plates on the four sides; each verticality-adjusting support leg is provided with a high-strength sleeve and a verticality-adjusting screw; the lining pile casing is provided with bolt holes; and after the bolt holes are aligned with those of the steel-pipe upright column pile, the lining pile casing and the steel-pipe upright column pile are fixed through strengthening bolts. The invention provides the construction device and the construction method, which make the verticality of the steel-pipe upright column pile meet a requirement by virtue of a multidirectional jacking effect, give consideration to upright column pile positioning and solve the problems that the positioning deviation is large because a center mark is lost after a pile hole is drilled and a verticality-adjusting device is complex to use and difficult for construction personnel to operate.

Description

technical field [0001] The invention relates to the positioning and vertical adjustment construction during the upside-down construction of one column by one steel pipe column in the process of hoisting and placing, and in particular to a rapid positioning and vertical adjustment device and construction method for large-diameter steel pipe column piles. Background technique [0002] With the development of the city, the construction technology has also been developed rapidly. Compared with the traditional open method, the upside-down method has the advantages of reducing foundation pit deformation, saving support costs, and shortening the construction period. It is an energy-saving and environmentally friendly green construction method. is widely adopted. One-column-one-pile construction is one of the core construction procedures of the upside-down method. Especially in the construction of large buildings, the number of one column and one pile is large, and multiple piles ar...

Problems solved by technology

[0005] The present invention proposes a fast positioning and vertical adjustment device and construction method for large-diameter steel pipe column piles. During the construction, the vertical adjustment progress of the vertical columns at multiple pile positions cannot match the problem of the pile foundation construction. That is, research and development of a vertical adjustment device that can quickly complete the vertical adjustment of the steel pipe column piles and is relatively cheap, provides a multi-directional jacking The lifting effect makes the verticality of the steel pipe column meet the requirements and takes into account the construction device and construction method of the positioning of the column pile, which solves the problems of large positioning deviation after the pile center mark is lost after the pile hole is drilled and the use of the vertical adjustment device is complicated and difficult for construction personnel to operate.
