Description

Technical Field

[0001] The utility model relates to the technical field of settlement monitoring, in particular to a deep underground space settlement monitoring device. Background Technique

[0002] Multiple settlement monitoring devices need to be deployed in deep underground spaces such as subway tunnels and subway station halls. Generally, they are static level gauges. A single device monitors a single point, and multiple devices cooperate to jointly monitor the settlement of an underground area.

[0003] The static level gauge mainly measures the vertical displacement change between two or more points based on the principle of communicating vessels or high-precision sensor technology. Among them, the hydraulic static level gauge calculates the liquid level change by measuring the change in liquid pressure, and then obtains the relative settlement value. The magnetostrictive, capacitive or ultrasonic static level gauges use different sensing technologies to achieve high-precision displacement measurement.

[0004] When installing this device, it needs to be paired with a special bracket. The bracket is installed on the wall through expansion bolts. A positioning bolt is provided at the top of the bracket. The flange of the monitoring device is directly sleeved on the bolt, and then tightened with a nut. However, after the device is locked, the angle in the horizontal direction cannot be adjusted finely. During long-term use, due to factors such as foundation settlement and temperature change, the installation state of the instrument may change, resulting in inaccurate measurement of the device. Therefore, a deep underground space settlement monitoring device is designed to solve the above problems. Content of the Utility Model
