Abstract

The invention provides an axial force checking, regulating and controlling system for a foundation pit servo steel supporting system and a method thereof, and the method is characterized in that a servo steel supporting system comprising a first movable joint, a first servo hydraulic system, a steel support, a second servo hydraulic system and a second movable joint which are connected in sequence is arranged on the inner side of an enclosure structure; horizontal distance measuring devices are arranged at the two ends of the first servo hydraulic system and the two ends of the second servo hydraulic system respectively, and a pressure measurement sensing device is installed on the first servo hydraulic system or the second servo hydraulic system; length deformation and axial force of the first movable joint, the first servo hydraulic system, the steel support, a second servo hydraulic system and the second movable joint in the servo steel support system are monitored in real time; deformation and axial force of the first movable connector, the first servo hydraulic system, the steel support, the second servo hydraulic system and the second movable connector inside are linked in real time, active regulation and control of the axial force of the servo steel support are achieved, and the problem of axial force loss of the steel support is effectively solved.

Description

technical field [0001] The invention belongs to the field of civil engineering construction, and in particular relates to a system and method for checking and regulating the axial force of a servo steel support system for a foundation pit. Background technique [0002] In traditional deep foundation pit engineering, concrete support or prestressed steel support structure is often set inside the enclosure structure as a means to control the deformation of the enclosure structure. However, due to the passive stress characteristics of these two support systems, it is necessary to compress the support after a certain deformation of the enclosure structure to provide sufficient support axial force, and the traditional prestressed steel support generally has the problem of axial force loss, making the traditional It is difficult for the internal support structure to meet the high requirements of foundation pit deformation control. In order to effectively meet the strict deformati...
