Description

Technical Field

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

[0002] During the construction of highway projects, it is necessary to coring the road surface to determine the thickness of each structure of the highway in order to detect the quality of the highway project. The existing announcement number is CN 216620942 U, which is a thickness detection device for highway construction. By rotating the adjustment plate, the limit bolt moves downward, so that the mounting plate can be well limited with the horizontal plane of the highway to prevent the mounting plate from sliding. A positioning drill is connected to the bottom of the movable rod. When performing thickness detection, the positioning drill can be driven deep into the ground by rotating the toggle rod. At the same time, a cleaning plate is connected to the side wall of the movable rod to conveniently clean the surrounding gravel to prevent the gravel from affecting the measurement data. At the same time, the cleaning plate can play a supporting role, preventing the positioning drill from going too deep and preventing the movable rod from tilting. However, the above equipment is cumbersome to operate during detection, which affects the efficiency of use. Utility Model Content
