Assembly type beam string steel support wireless monitoring system

Abstract

The invention relates to an assembly type beam string steel support wireless monitoring system. The system comprises an internal force measuring system and a deformation measuring system. The internalforce measuring system comprises axial force boxes, wherein the axial force boxes are arranged in the middle of a beam string structure steel pull rod, at the tail end of a beam string structure steel supporting rod and at the tail end of a foundation pit steel support, and the axial force boxes monitor axial force in real time and feeds back the axial force to a monitoring terminal. The deformation measuring system comprises 3D deformation monitoring equipment and an inclinometer. The 3D deformation monitoring equipment comprises a laser range finder fixed to an enclosure structure and a CCDposition sensor fixed to the top of the foundation pit steel support or the top of a stand column used for supporting the foundation pit steel support, a laser sensor is aligned with the CCD positionsensor, the laser range finder serves as a reference, displacement of the CCD position sensor in three-dimensional space is monitored in real time, and is fed back to the monitoring terminal. The inclinometer monitors deep horizontal displacement of the enclosure structure in the perpendicular direction towards the interior of the foundation pit in real time and feeds back the displacement to themonitoring terminal.

Description

technical field [0001] The invention relates to an assembled string string beam steel support wireless monitoring system, which belongs to the technical field of foundation pit monitoring. Background technique [0002] Since the 1980s, my country's urban construction has developed rapidly, especially the rapid development of high-rise buildings and underground projects. The importance of foundation pit engineering has gradually been recognized by people. Accumulation continues to increase. However, in the practice of foundation pit engineering, there is often a certain difference between the actual working state of the project and the design working condition, and the design value cannot fully and accurately reflect various changes in the project. Therefore, under the guidance of theoretical analysis, the on-site engineering is planned Monitoring becomes very necessary. [0003] In the existing technology, the monitoring of the internal force of the foundation pit steel sup...

However, in the practice of foundation pit engineering, there is often a certain difference between the actual working state of the project and the design working condition, and the design value cannot fully and accurately reflect various changes in the project. Therefore, under the guidance of theoretical analysis, the on-site engineering is planned monitoring becomes necessary

[0003] In the existing technology, the monitoring of the internal force of the foundation pit steel support and the surrounding deformation needs to be carried out manually. The manual operation is not only inefficient, but the data processing is cumbersome, and the human error is large, and it is impossible to realize real-time monitoring and real-time early warning, which is safe for the foundation pit.
