Abstract

The invention provides a tunnel monitoring mechanism and a sedimentation monitoring method for a tunnel. The tunnel monitoring mechanism comprises an installing assembly and at least one fiber bragg grating pulling wire sensor, wherein the fiber bragg grating pulling wire sensor is connected with a demodulator; the installing assembly comprises a plurality of connecting elements and at least one positioning element; the connecting elements are arranged on the top of the tunnel; a connecting wire of one fiber bragg grating pulling wire sensor is connected onto one connecting element; the at least one positioning element is arranged on the inner wall of the tunnel; the connecting wire is positioned by the positioning element so that the fiber bragg grating pulling wire sensor is arranged at one side near the inner wall of the tunnel. The tunnel monitoring mechanism and the sedimentation monitoring method solve the problems of low tunnel sedimentation monitoring precision and real-time monitoring incapability in the prior art; meanwhile, the problem of interference on other work procedures during the monitoring can be solved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a tunnel monitoring mechanism and a settlement monitoring method for the tunnel. Background technique [0002] With the construction of a large number of tunnels such as railways and highways, accidents such as tunnel collapses occur from time to time, and it is imperative to strengthen tunnel safety monitoring. In the prior art, the most important monitoring for the tunnel is the monitoring of the settlement of the top of the tunnel. At present, the main method is to use the total station manual monitoring. However, the monitoring of the total station requires manual point-by-point monitoring, which is time-consuming and labor-intensive, and cannot be monitored in real time. At the same time, the monitoring accuracy is related to the operation of the staff, resulting in its measurement The error is large. Contents of the invention [0003] The main purpose of the pres...
