Description

Technical Field

[0001] This utility model relates to the field of tunnel deformation monitoring technology, and in particular to a tunnel deformation monitoring device. Background Technology

[0002] Tunnel engineering, due to its massive investment, long route length, and high degree of concealment, places high demands on construction quality, schedule, and safe operation after completion. During the construction and operation of tunnels, changes in soil and rock loads and construction deviations can cause a certain degree of deformation. Currently, the most common method is to inspect and observe the apparent deformation of the inner surface of the tunnel, and to monitor the flatness, inclination, and displacement of the inner surface of the support structure by setting up fixed monitoring points at certain intervals. However, this monitoring method is inefficient and cannot directly observe the location of deformation in the tunnel. Therefore, a tunnel deformation monitoring device is proposed to solve the above-mentioned technical problems. Utility Model Content
