Description

Technical Field

[0001] The invention belongs to the technical field of road construction, and in particular relates to a thickness detection device for a roadbed and pavement. Background Art

[0002] The core drilling method is a commonly used method for detecting the thickness of a road surface. In the prior art, a drilling rig is used in conjunction with a core drilling barrel for sampling and testing.

[0003] During the inspection, a manual handheld drill is required. The drill drives the core barrel to rotate and drill vertically into the road surface. After drilling to a predetermined depth, the core sample inside the core barrel is taken out, and then the core sample is measured to obtain the thickness of the road surface. In the process of taking out the core sample from the inside of the core barrel, the drill needs to be lifted upward, and then the outside of the core barrel is knocked and vibrated to make the core sample slide down from the core barrel to complete the sampling. It can be seen that during the sampling process, the operator not only needs to lift the drill, but also knock the core barrel, which requires at least two people to cooperate to complete, with high manpower expenditure and poor convenience of use.

[0004] Therefore, it is necessary to design a roadbed and pavement thickness detection device that reduces labor costs and improves ease of use to solve the current technical problems. Summary of the invention
