Description

Technical Field

[0001] The utility model relates to the technical field of tunnel detection, in particular to a disease detection device for a tunnel inspection road. Background Art

[0002] The main function of the maintenance road is to allow maintenance personnel and tunnel users to handle emergencies without interfering with each other's traffic. For example, it can be used for emergency escape when an accident occurs, so that drivers and passengers can stay away from the accident vehicle and leave the road. At the same time, the lower space of the maintenance road is often used to install pipes, cables, etc. If the maintenance road is damaged (such as missing, warped, tilted, etc.), it will not only reduce the efficiency of personnel escape, but also cause problems with the pipes and cables installed under the maintenance road. Therefore, it is necessary to regularly inspect and maintain the tunnel maintenance road. However, there is currently no equipment on the market that can detect maintenance roads, and it can only be detected by manpower, resulting in a huge waste of manpower. Utility Model Content
