Abstract

The invention provides an axial force and displacement dual-adjustment system for a steel support. The axial force and displacement dual-adjustment system for the steel support comprises a control device, a power output device and an adjustment device which is arranged at an end part of the steel support; the adjustment device is used for loading axial force and adjusting displacement of the steel surface, and transmitting the loaded axial force value and displacement data of the adjustment device which acts on the steel support to the control device in real time; the power output device is connected with the adjustment device and provides power for the adjustment device; the control device is connected with each of the adjustment device and the power output device, receives the axial force value and the displacement data transmitted by the adjustment device, and controls the power output of the power output device. According to the axial force and displacement dual-adjustment system for the steel support provided by the invention, the axial force and the displacement of the steel support can be adjusted and controlled simultaneously, and the difficult problem that the axial force of the steel support changes because of the displacement of the steel support caused by the influence of external environment in practical construction is solved.

Description

technical field [0001] The invention belongs to the field of building construction, and relates to a system and an adjustment method for dual adjustment of axial force and displacement of steel supports. Background technique [0002] At present, in building construction, reinforced concrete is used as the horizontal support in the pit for large-scale underground excavation, but this method has high construction costs and cannot be reused, especially after the construction is completed. The demolition workload is heavy, the noise is large, and the pollution is serious , is not conducive to environmental protection. At present, another method is to use steel support as the horizontal support after underground excavation, which overcomes the shortcomings of concrete horizontal support, and has the advantages of reusability and environmental protection. [0003] When a large-scale foundation pit adopts a two-way steel support structure, it is usually necessary to apply a certai...
