Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit measurement, in particular to a vertical monitoring device for the ground surface around a deep foundation pit. Background Art

[0002] A deep foundation pit refers to a project with an excavation depth of more than 5 meters, or a project with a depth of less than 5 meters but particularly complex geological conditions, surrounding environment and underground pipelines. During the construction process, the vertical displacement of the surface around the deep foundation pit is an important factor causing damage to surrounding roads and buildings. Vertical displacement monitoring can timely reflect the settlement of the soil around the foundation pit after excavation. Monitoring of the surrounding surface vertical displacement can not only guide the safe construction of deep foundation pit projects, but also play a decisive role in ensuring the safety of the surrounding environment.

[0003] The existing vertical displacement monitoring uses a laser ranging sensor to measure and record the depth of the deep foundation pit, and calculates the displacement data based on the recorded data. However, the existing vertical displacement monitoring device cannot adjust the measurement angle and can only be placed on a flat road surface for measurement. Once the road surface tilts, the laser ranging sensor will tilt accordingly, which will lead to errors in the measured data and affect the progress of the project construction. Utility Model Content

The limiting ring and the limiting plate are sequentially arranged in the side opening of the mounting tube, and the guide block is arranged at the end of the limiting plate and is adapted to the guide groove.

[0008] As a preferred solution, the length of the guide groove is greater than the length of the guide block.

[0009] As a preferred solution, there are four guide blocks, which are symmetrically distributed along the side of the limiting plate.

[0010] As a preferred solution, both the first end face tooth ring and the second end face tooth ring are circular rings, and the end faces of the two are provided with teeth that mesh with each other.
