Description

Technical Field

[0002] At present, with the development of urban high-rise buildings, subways and major municipal engineering construction, more and more deep foundation pit projects are emerging. The excavation of deep foundation pits will cause deformation of the surrounding soil, which will affect the foundation pit retaining structure and the environment. In serious cases, it will affect the normal use of the structure and easily cause casualties and financial losses. Therefore, monitoring of foundation pit deformation is particularly important.

[0003] A commonly used device for monitoring the deformation of foundation pits of high-rise buildings is an inclinometer (clinometer). Inclinometers can be used to monitor the inclination and deformation of soil or structures. By installing them on the surface or structures around the foundation pit, they can monitor the changes in the inclination angle in real time and detect foundation settlement or deformation in a timely manner.

[0004] However, when installing the inclinometer, it is necessary to use tools to turn the fixing bolts to install it. The installation and disassembly is rather cumbersome, time-consuming and labor-intensive, and it is not convenient to maintain the inclinometer. In addition, when it is necessary to monitor different positions of the deep foundation pit, it is necessary to adjust the height by rotating the support frame, and then fix the legs, and then monitor through the monitoring device body. The operation is rather cumbersome, which reduces the monitoring efficiency and reduces the practicality of the inclinometer. Utility Model Content
