Problems solved by technology

At present, the method of monitoring the settlement of the tunnel mainly adopts the manual monitoring of the total station. 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 large measurement errors and low measurement accuracy

Abstract

The invention provides a tunnel bottom plate settlement monitoring device. The device comprises fixed pipelines, at least one fiber grating sensor is arranged on each fixed pipeline, a plurality of fixed pipelines provided with the fiber grating sensors form a long-distance fiber grating settling pipe, and the long-distance fiber grating settling pipe is used for being fixed to a bottom plate of atunnel; the device comprises a demodulator, the fiber bragg grating sensors are connected with the demodulator, the demodulator can receive and process monitoring data of the fiber bragg grating sensors, and the device also comprises an optical cable which is connected with a reserved standard communication interface arranged on the fiber bragg grating settling tube.

Description

technical field [0001] The patent of the present invention relates to the technical field of tunnel monitoring, in particular to a tunnel floor settlement monitoring device and method. Background technique [0002] At present, in tunnel construction, the subsidence of the tunnel floor is a common problem. Many major safety risks or accidents in the tunnel and surrounding construction facilities may be caused by the deformation of the tunnel caused by the settlement of the tunnel floor. At present, the method of monitoring the settlement of the tunnel mainly adopts the manual monitoring of the total station. 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 large measurement errors and low measurement accuracy. Contents of the invention [0003] In view of ...
