[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. The pavement of highway engineering will inevitably wear out over time during use. The thickness of the pavement will be tested, so thickness testing equipment is needed.

[0003] When measuring the road surface, a ruler is generally used to place it against the roadbed and measure its height to the road surface to measure its thickness, or a drilling tool is used to sample the road surface, and then the height of the sampling column is detected using the corresponding tool. The above two methods generally use a ruler tool when measuring the road. During the measurement, errors in observation are likely to lead to measurement errors, so the measured values ​​are often not accurate enough.

[0004] For this purpose, a thickness detection device is proposed. Utility Model Content
