Description

Technical Field

[0001] The present invention relates to the technical field of tunnel cross-section deformation detection equipment, and particularly relates to a tunnel cross-section deformation detection device. Background Art

[0002] A tunnel cross-section detector is a professional instrument used to measure the advance excavation of a tunnel cross-section. At the same time, it can also be used as a long-term monitoring tool for tunnel contour deformation. However, there are some limitations and problems in the prior art, which limit the efficiency and accuracy of tunnel cross-section detection:

[0003] Inconvenient to move: Existing tunnel cross-section detectors usually need to be placed on a triangular support, which limits their mobility in the tunnel and makes it difficult and time-consuming to perform detections at different positions.

[0004] Complex operation: In order to achieve a comprehensive detection of the tunnel cross-section, it is usually necessary to set up a tunnel cross-section detector on the inner wall of the tunnel at a certain distance for each section, which increases the complexity of the operation and the demand for human resources.

[0005] High cost: Since it is necessary to set up detectors at multiple positions, this leads to a significant increase in the cost of tunnel cross-section detection, especially in large tunnel projects.

[0006] Safety issues: Frequent movement and setting up of detection equipment in the tunnel increase the safety risks for workers, especially in tunnels with heavy traffic or unstable structures.

[0007] Discontinuous data collection: Due to the fixed position limitation of the detector, it is difficult to achieve continuous and comprehensive detection of the tunnel cross-section, which may lead to incomplete and inaccurate data.
