[0002] The thickness of the road has a vital impact on the quality of the road, so radial sampling and testing of the road is required after the road is built.

[0003] In the prior art, the road thickness is usually detected by drilling a cylindrical sample on the road surface with a rotating sleeve, and the thickness of the sample is measured after the sample is taken out to obtain the thickness of the road surface.

[0004] After the existing rotating sleeve drills the road surface, the drilled samples cannot completely leave the road surface with the rotating sleeve. In actual situations, many samples cannot leave the road surface with the rotating sleeve, and the drilled samples need to be taken out from the road surface by clamps, which increases the workload of workers.

[0032] When the second sleeve drills the sample downward until the top of the sample enters the concave cavity of the clamping block, the top of the sample enters the concave cavity from the opening of the concave cavity. Since the concave cavity is in a gradual shape, the closer the top of the sample is to the bottom of the concave cavity, the pressure on the sample from the concave cavity gradually increases, thereby causing the sample to be stuck in the second cylinder. When the second cylinder is taken out from the road surface, the sample can be taken out together. This avoids the situation where workers need to use clamps to take the sample out of the road surface. After taking out the second cylinder, the sample can be separated from the second cylinder by knocking on the second cylinder. The operation is simple and convenient, reducing the labor intensity of workers.
