[0001] The utility model relates to the technical field of highway engineering detection, in particular to a thickness detection device for engineering highways. Background Art

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. In highway engineering, the thickness of each layer is closely related to the overall strength of the road. That is, only when the thickness is guaranteed can the strength of each layer and the overall road surface be guaranteed. Therefore, it is often necessary to measure the thickness of the road surface in highway engineering.
