Problems solved by technology

The loss of tunnel lining blocks seriously threatens the operation safety of railway tunnels, causing equipment damage and economic losses, and causing railway operation accidents and threatening the safety of passengers
[0005] At present, the treatment methods for tunnel lining diseases mainly rely on manual regular inspection and timely treatment after the event, which has shortcomings such as poor timeliness and low safety. Real-time monitoring and active treatment of tunnel lining diseases have not yet been realized, and it is difficult to effectively ensure the safe operation of railway tunnels

Embodiment 1

[0041] Such as Figure 1-3 As shown, Embodiment 1 of the present disclosure provides a non-contact railway tunnel lining defect monitoring and early warning system, including monitoring equipment 1 arranged at the spandrel in the railway tunnel, and the monitoring equipment includes ultrasonic detectors communicating with each other and infrared digital imager;

[0042] The ultrasonic detector perceives the difference in the ultrasonic energy field caused by the defective disease, and converts the wave signal into an electrical signal and transmits it to the infrared digital imager. The infrared digital imager obtains the spatial orientation information of the defect source according to the obtained electrical signal, and the Transient image acquisition of defective lesions.

[0043] Specifically, during the operation period, the spandrels on both sides of the railway tunnel are equipped with monitoring equipment integrating high-precision ultrasonic detectors and high-defini...

Embodiment 2

[0055] Embodiment 2 of the present disclosure provides a non-contact railway tunnel lining defect monitoring and early warning method, including the following steps:

[0056] Obtain real-time information on the spatial orientation and image information of the defect source from the monitoring equipment deployed at the spandrel position on the inner wall of the tunnel;

[0057] According to the obtained information, judge the damage degree of the lining falling block, and when the damage degree is greater than the preset threshold, send the alarm information and the defect source location information to the monitoring terminal and / or the train control terminal and / or the cloud server.

[0058] specific,

[0059] (1) Install monitoring equipment. The railway tunnel lining disease monitoring equipment is installed at the spandrels on both sides of the railway tunnel, and the monitoring equipment is installed sequentially along the tunnel axis at intervals of 15 meters, so as to ...

Abstract

The disclosure provides a non-contact railway tunnel lining defect monitoring and early warning system and method, including monitoring equipment installed at the spandrel in the railway tunnel, and the monitoring equipment includes an ultrasonic detector and an infrared digital imager that communicate with each other The ultrasonic detector perceives the difference in the ultrasonic energy field caused by the defective disease, and converts the wave signal into an electrical signal and transmits it to the infrared digital imager, and the infrared digital imager obtains the spatial orientation information of the defective disease source according to the obtained electrical signal, Instantaneous image collection of defective diseases; this disclosure realizes real-time monitoring and remote early warning of railway tunnel lining block defects during the operation period, effectively avoids high-risk situations such as false alarms and missed alarms, and is conducive to ensuring the safety of railway tunnel operations during the operation period .

Description

technical field [0001] The present disclosure relates to the technical field of tunnel monitoring, in particular to a non-contact railway tunnel lining defect monitoring and early warning system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the rapid development of the economy, the demand for transportation is increasing day by day, and the construction of infrastructure such as railways, highways, and municipal infrastructure continues, and tunnel engineering has ushered in a new era of development. [0004] The inventors of the present disclosure found that due to limitations of existing tunnel construction technologies, tunnel diseases represented by lining cracks and water leakage are common, and the tunnel disease rate is as high as 52.4%. In particular, engineering disasters such as tunnel lining cracking and wa...
