Description

Technical Field

[0001] The utility model relates to the technical field of ground penetrating radar, in particular to a ground penetrating radar measuring device for tunnel. Background Technique

[0002] When building a highway tunnel, the monitoring, maintenance and management of the highway tunnel begin to be highly valued. Among them, the quality of the tunnel lining directly affects the service performance and life of the tunnel. Therefore, the detection of the tunnel lining quality is particularly important. At present, the relatively fast detection method is to use the ground penetrating radar detection technology for non-destructive detection.

[0003] When the existing ground penetrating radar measuring device for tunnel is in use, it usually measures multiple survey lines inside the tunnel simultaneously during one forward movement. When changing different survey lines after one measurement, it is necessary to disassemble and reassemble the bracket for fixation, which affects the work efficiency.

[0004] Therefore, aiming at the problem that the above-mentioned ground penetrating radar measuring device for tunnel is not convenient for quickly replacing the radar survey line, and it is necessary to disassemble and reassemble the bracket for fixation, and the operation is relatively cumbersome, a regulating structure can be designed to drive the ground penetrating radar to move to achieve the purpose of quickly replacing the survey line. Content of the Utility Model
