Embodiment Construction

[0041] Below in conjunction with accompanying drawing and specific embodiment, a kind of " one pile two column " construction verticality adjusting device and using method of the present invention will be further described in detail:

[0042] The verticality adjustment device for "one pile with two columns" construction of the present invention is a device for adjusting the verticality of double steel pipe columns. The double steel pipe columns 27 are two steel pipe columns arranged side by side at intervals by welding with steel plates 28, and each steel pipe Columns are welded with studs arranged in rows in the circumferential direction. In this embodiment, the steel plate 28 between the two steel pipe columns is Q345B steel plate. The distance between the adjacent steel plates 28 is 4000mm. When the steel plates 28 are welded, the steel plates 28 should avoid the studs in the circumferential direction of the steel pipe column.

[0043] Before the double steel pipe column 27...

Abstract

The invention relates to a perpendicularity adjusting device for one-pile two-column construction and a using method. The perpendicularity adjusting device comprises a base, a perpendicularity adjusting disc and a perpendicularity adjusting frame, wherein the base is used for being fixed to a pile hole opening and is rectangular, an avoiding hole corresponding to a pile hole is formed in the center of the base, the perpendicularity adjusting disc is placed on the base, the perpendicularity adjusting disc is number sign-shaped and comprises a first adjusting frame and positioning frames, double steel pipe columns can penetrate through the first adjusting frame, the positioning frames are fixed to the side edges of the first adjusting frame, first adjusting bolts for adjusting the perpendicularity of the double steel pipe columns are arranged on the first adjusting frame, second adjusting bolts for adjusting the flatness of the perpendicularity adjusting disc are arranged on the positioning frames, the first adjusting frame is arranged corresponding to the avoiding hole, the perpendicularity adjusting frame comprises supporting legs fixed to the base and an adjusting frame fixed to the upper portions of the supporting legs, the adjusting frame comprises a second adjusting frame vertically corresponding to the first adjusting frame, and a third adjusting bolt used for adjusting the perpendicularity of the double-steel-pipe column is arranged on the second adjusting frame. According to the perpendicularity adjusting device, the perpendicularity adjusting precision of the double-steel-pipe column is ensured.

Description

technical field [0001] The invention belongs to the technical field of building underground structure construction, and in particular relates to a verticality adjustment device for "one pile and two columns" construction and a use method. Background technique [0002] With the rapid development of the country's technology and economy, large-scale construction projects are developing in the direction of high depth. Compared with the traditional open method, the reverse method of underground engineering has the advantages of reducing foundation pit deformation, saving support costs, and shortening the construction period. An energy-saving and environmentally friendly green construction technology has led to more and more popular applications of reverse construction technology. [0003] The construction of the reverse method includes "one pile with one column" and "one pile with two columns". "One pile with one column" and "one pile with two columns" are used as the main suppor...
