Drilling holes on the ground is a common means for road thickness detection, that is, drilling holes on the road, and then measuring the thickness of the corresponding material layer in the ground hole to determine whether the thickness of the corresponding layer of the road meets the design requirements. The common equipment for drilling holes on the ground is a motor-driven auger rod. The drilling process of the auger rod on the ground produces slag which is accumulated around the ground hole. After the auger rod is removed, the debris around the ground hole is easy to fall into the ground hole, and the slag in the ground hole needs to be cleaned again, which affects the efficiency of road thickness detection. Therefore, it is necessary to design a road thickness detection device to improve the efficiency of road thickness detection. SUMMARY
