Description

technical field

[0001] The invention relates to the related technical field of subway tunnels, in particular to a hidden repair device for deformation detection of subway tunnels based on a total station. Background technique

[0002] During the construction of subway tunnels, it is necessary to build shield tunnel segments inside the subway tunnels to support the subway tunnels. However, due to the influence of the external environment, deformation of the subway tunnel segments will occur after long-term use. In order not to Affecting the normal use of the subway tunnel requires regular monitoring and repair. The existing monitoring technology is usually carried out with the cooperation of the total station. When the total station detects the deformation of the subway tunnel segment, the information is transmitted to the Monitor the platform for remediation work;

[0003] However, the existing subway tunnel segment deformation repair devices still have certain defects, suc...
