The highway detection comprises compression resistance detection, water seepage detection, flatness detection, thickness detection and the like. Currently, in a thickness detection project, the most common method is to vertically drill into the underground of a road through a core drill, drill the road into the underground by using a drill bit to take out a section of sample of the paved road, and measure the thickness manually. However, when the sample in the drill bit is taken out, the outer wall of the drill bit is knocked to generate vibration so as to drive the road sample in the drill bit to slide down, and then the thickness of the road sample is manually measured, so that time and labor are wasted, and the working efficiency is low. In view of this, we propose a thickness detection device for road engineering supervision.
