Description

Technical Field

[0001] The utility model relates to the technical field of deep foundation pit excavation monitoring, in particular to a deep foundation pit excavation monitoring device close to an existing building. Background Art

[0002] Since the deformation of deep foundation pits during the excavation process may have extremely serious adverse effects on the existing buildings adjacent to them, it will not only destroy the stability of the basic structure of the existing buildings, causing uneven settlement or overall sinking, but may even cause the buildings to tilt or collapse in severe cases, and will cause cracks or settlement in the walls and ground of the existing buildings. These cracks will not only affect the aesthetics of the buildings, but may also damage the waterproof layer and cause problems such as seepage and leakage. Therefore, in the process of deep foundation pit excavation, inclinometers are needed to regularly collect and analyze data, evaluate the stability and rationality of the monitoring data, promptly discover abnormal monitoring data, and take corresponding measures.

[0003] However, most of the existing inclinometers need to be manually operated by operators during use, which is easily affected by human factors, resulting in unstable measurement accuracy and difficulty in ensuring data reliability. At the same time, manual operation requires a lot of time and manpower, which reduces the efficiency of monitoring. In addition, manual operation in dangerous environments such as deep foundation pits also has certain safety hazards, increasing the risk of accidents. Before use, the existing inclinometer rods need to be firmly connected to the wires using threads and fastening screw sleeves. The installation process is relatively cumbersome and requires delicate operations to ensure the tightness and reliability of the connection. At the same time, the threads and fastening screw sleeves are also susceptible to corrosion and wear, which may affect the durability and stability of the connection, increasing the difficulty and cost of maintenance and replacement.
