[0002] With the development of science and technology, a large number of traffic roads need to be built. During use, the structure will deform under load and the internal stress of the components will further develop. Road inspection refers to the inspection of the quality of the construction road to ensure that the strength and quality of the road can meet the construction requirements and traffic requirements. Therefore, it is necessary to drill holes in the ground through a sampling device.

[0003] A sampling device for road engineering inspection with a Chinese patent document publication number of CN218411774U discloses a driving motor arranged on a movable plate, which can drive a spiral blade to rotate, thereby drilling holes and taking samples on the road surface. The protective pipe arranged can play a protective role, which can effectively reduce the danger to workers caused by the rotation of the spiral blade.

[0004] Although the above-mentioned sampling device improves the protective effect of the spiral blade during rotating sampling, the device requires other devices to assist in sample collection when performing a single drill rod sampling, and is not capable of collecting samples during layered testing of road projects, resulting in poor practicality and convenience when using the device, which seriously affects the working efficiency of the sampling device. A technician in this field provides a sampling device for road testing to solve the problems raised in the above-mentioned background technology. Utility Model Content
