One-column-with-one-pile steel column positioning verticality-adjusting system and construction method based on reverse construction method

Abstract

The invention discloses a one-column-with-one-pile steel column positioning verticality-adjusting system based on a reverse construction method. The one-column-with-one-pile steel column positioning verticality-adjusting system comprises a supporting device, a positioning guiding device and a verticality adjusting device; the supporting device comprises a supporting derrick; the positioning guiding device is composed of a plurality of positioning guiding sets which are arranged in the circumferential direction of a steel column at intervals; and the verticality adjusting device comprises high-pressure gas supply equipment, a total gas feeding pipe, a controller, a pressure gauge and high-pressure rubber cylinders. The invention further provides a one-column-with-one-pile steel column positioning verticality-adjusting construction method based on the reverse construction method. The one-column-with-one-pile steel column positioning verticality-adjusting system and construction method have the beneficial effects that the verticality adjusting device is designed, the high-pressure gas supply equipment communicates with the high-pressure rubber cylinders, and the pressure gauge is arranged at an inlet of a branch gas pipe and connected with the controller; by adjusting the gas pressure in all the high-pressure rubber cylinders, the verticality of the steel column is secondarily adjusted, the adjusting precision is high, and the flexibility is good; and the verticality of the steel column can be monitored in real time through a deviation surveying structure, feedback adjustmentis conducted according to a detection structure, and the construction quality of the steel column is sufficiently ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel column positioning and vertical adjustment system in one column and one pile based on the reverse method and a construction method. Background technique [0002] With the leap-forward development of urban construction, large-scale high-rise buildings have sprung up. The foundation of high-rise buildings will face the problem of deep foundation pit engineering during the construction process. Compared with the traditional deep foundation pit construction method, the upside-down method has many advantages such as protecting the environment and shortening the construction period. An effective economic means for a conservation-minded society. In reverse construction, the surrounding diaphragm wall and internal support piles are usually constructed first to form a vertical load-bearing system for reverse construction. The support piles are generally designed i...
