A hidden repair device for subway tunnel deformation detection based on total station

Abstract

The invention discloses a hidden repairing device for deformation detection of subway tunnels based on a total station instrument. The tunnel segment is composed of a cylindrical structure; the positioning box is placed inside the tunnel segment of the subway shield tunnel; the infrared ranging mechanism, the infrared ranging mechanism installed outside the positioning box measures the repaired deformation distance ; reset mechanism, the reset mechanism is arranged inside the positioning box; auxiliary mechanism, the auxiliary mechanism is set corresponding to the reset mechanism, and the lateral axis of the auxiliary mechanism is perpendicular to the longitudinal center axis of the fixed cylinder. The total station-based hidden repairing device for deformation detection of subway tunnels has sufficient tension, and the overall repairing efficiency is high, and can perform quantitative repairs without causing excessive or insufficient repairs.

Description

technical field [0001] The invention relates to the technical field of subway tunnels, in particular to a hidden repair device for deformation detection of subway tunnels based on a total station instrument. Background technique [0002] In the construction of subway tunnels, shield tunnel segments need to be built inside the subway tunnels to support the subway tunnels. However, due to the influence of the external environment, after long-term use, the deformation of the subway tunnel segments will occur. Affecting the normal use of subway tunnels, it needs to be regularly monitored and repaired. The existing monitoring technology is usually carried out with the cooperation of the total station. When the total station monitors the deformation of the subway tunnel segment, the information is transmitted to Monitoring platform, and then carry out repair work; [0003] However, the existing subway tunnel segment deformation repair device still has certain defects, such as: ...
