Real-time monitoring system plays significant role during foundation pit excavation process. It will provide real-time data (such as the deformation and structural condition of foundation pit) for the operator to avoid the occurrence of any on site accident. To compare with other monitoring method, the real-time monitoring system has the advantage of strong adaptability, smaller impacts by varies weather conditions and extremely high accuracy. Sensor distribution and the choice of system model are different from varies depth and scale of the foundation pit. It is very important to choose the most suitable plan for the construction.
Monitoring system layout relay on site structure information. All sensors used should be deployed before construction. The main contents of foundation pit monitoring include foundation pit structure support monitoring, monitoring of surrounding structures (building settlement, tilt and crack monitoring) and other aspects. Main equipment that used in this monitoring system are monocrystalline silicon hydro leveling sensor, inclination sensor, osmometer, crack meter, displacement sensor and bolt pre-tightening force sensor.
To sum up, in the foundation pit engineering structure safety monitoring system, mainly for stress/strain of the foundation pit, settlement, displacement and other parameters, can be used to this kind of various types of sensors and equipment monitoring project, different models, so when making sensor equipment selection should consider mainly range, sensitivity, precision and working environment factors, for the convenience of management at the same time, ZHYQ uses the system monitoring centre to implement a unified and centralized management of all front-end sensor equipment, IOT gateway, data acquisition equipment and IOT monitoring cloud platform.
