Problems solved by technology
During the inspection process, inspectors need to stand on the moving vehicle and the platform, hold the geological radar antenna close to the tunnel lining by hand, and move with the vehicle. This method has the following significant disadvantages: 1. The radar antenna is heavy , human lifting is prone to fatigue, and the safety risk is great

The invention discloses a device for detecting a tunnel lining by using a geological radar antenna. The device comprises a base, a cross rod and a first telescopic rod. At least three moving wheels are arranged at the bottom of the base, and a second telescopic rod is vertically arranged on the base; the cross rod is horizontally arranged, and the tail end of the cross rod is fixed at the top endof the second telescopic rod; the first telescopic rod is vertically arranged, the top end is fixed to the top end of the cross rod, and the tail end of the first telescopic rod is provided with a movable clamping plate; and a radar antenna is clamped on the movable clamping plate. Manual lifting is replaced, and the problems that in the side wall primary lining and secondary lining detection process, manual lifting is prone to fatigue, the vehicle running speed is uneven, detection data is discontinuous, and the safety risk is large are solved; and blocking of obstacles such as reinforcing steel bars can be overcome to make the radar antenna tightly attached to the back of the obstacles for primary lining, and the heights of the two sides of the obstacle are adjusted, so that the accuracy, continuity and stability of collected data are guaranteed, the primary lining detection quality and efficiency are improved, and labor and mechanical expenses are reduced.
Description
technical field [0001] The invention belongs to the field of tunnel lining detection and relates to a device for detecting tunnel lining using a geological radar antenna. Background technique [0002] The surrounding rock and primary support of tunnels in mountainous areas of highways are the main force-bearing structures of tunnels, and the secondary concrete lining is mainly used as a safety reserve. The actual thickness of the tunnel plays a vital role in the safety and quality of the tunnel. Therefore, the tunnel construction quality must be inspected in time during the construction process to eliminate hidden dangers. [0003] At present, the foreign GSSI ground-penetrating radar is mainly used in the process of tunnel side wall lining inspection in highway tunnels. It is necessary to attach the radar antenna to the lining inspection site, and transmit and receive electromagnetic waves through the antenna during the movement process, so as to scan the tunnel lining. d...
