Ground penetrating radar vehicle suitable for tunnel lining quality detection

Abstract

The invention discloses a ground penetrating radar vehicle suitable for tunnel lining quality detection. The ground penetrating radar vehicle comprises a frame. A walking mechanism is arranged at the bottom of the frame, a radar antenna fixing mechanism is arranged on the frame, a lifting mechanism is arranged between the radar antenna fixing mechanism and the frame, a direction adjusting mechanism is arranged at the bottom of the lifting mechanism, and an inclination angle recorder used for detecting the inclination angle of the lifting mechanism is arranged on the frame. The ground penetrating radar vehicle has the advantages that a radar antenna is clamped through the radar antenna fixing mechanism, the height of the radar antenna is adjusted through the lifting mechanism, the direction of the lifting mechanism or the radar antenna fixing mechanism is adjusted through the direction adjusting mechanism, the inclination angle of the lifting mechanism is recorded through the inclination angle recorder in the moving process to obtain the height of the radar antenna, and the walking distance of the radar vehicle is obtained through a pedometer, so that the accurate position a measured tunnel lining is obtained.

Description

technical field [0001] The invention relates to tunnel detection, in particular to a ground-penetrating radar vehicle suitable for tunnel lining quality detection. Background technique [0002] Tunnel engineering has played an indispensable role in the rapid development of the national economy, and the quality of tunnels is closely related to the safety of people's lives and properties. Therefore, efficient and accurate inspection of tunnel safety quality can avoid safety accidents. [0003] The tunnel inspection project needs to complete the following inspection items: whether there is over-excavation or under-excavation on the rock surface of the tunnel; whether there is a cavity or gap between the rock surface and the primary lining, and between the primary lining and the secondary lining; Meet the design requirements; whether the distribution of steel skeleton and reinforcement meets the design requirements. In order to realize the detection of the above-mentioned tunn...

AI Technical Summary

Problems solved by technology

However, due to the characteristics of the ring structure of the tunnel and the complexity of the construction environment, it is inconvenient to use the ground penetrating radar detection tool in the tunnel

In the process of using ground penetrating radar in tunnels, radar signal interference often occurs, ground penetrating radar antennas cannot be attached to the tunnel wall, lack of portable devices for clamping ground penetrating radar, and poor mobility during detection, etc.
