Foundation Pit Horizontal Support Axial Force, Displacement Load Sensitive Servo Monitoring and Compensation System

Abstract

The invention relates to a load sensitive servo monitoring compensation system for horizontal support axial force and displacement of a foundation pit. The system comprises a follow-up self-locking force increasing hydraulic cylinder, a load sensitive hydraulic logic control system and a servo compensation control system, wherein the load sensitive hydraulic logic control system and the servo compensation control system are in communication connection in a wired or wireless mode, the follow-up self-locking force increasing hydraulic cylinder is connected with the load sensitive hydraulic logiccontrol system through a hydraulic oil circuit, the servo compensation control system carries out real-time data collection and calculates and processes the collected data, the servo compensation control system sends an instruction to the load sensitive hydraulic logic control system so as to control the state of the follow-up self-locking force increasing hydraulic cylinder, and the real-time load support state of each steel support point of the foundation pit is continuously tracked, compensated and displayed.

Description

technical field [0001] The invention relates to the technical field of underground and foundation engineering construction, in particular to a foundation pit horizontal support axial force, displacement load sensitive servo monitoring compensation system. Background technique [0002] With the rapid development of human social civilization and the rapid emergence of large and super-large cities, large-scale projects such as subway stations, railway passenger stations, open-cut tunnels, municipal squares, and bridge foundations are increasing, and the scale of underground space development is increasing. It has greatly promoted the rapid development of foundation pit engineering theory and technical level, and accelerated the demand for deep foundation pit engineering in urban rail transit and high-rise super high-rise buildings. With the rapid development of underground engineering in my country, safety issues in the process of foundation pit excavation also received more and ...
