Description

Technical Field

[0001] The utility model relates to the technical field of roadbed detection, in particular to a roadbed and pavement thickness detection device. Background Art

[0002] As the core structural layers of road construction, the thickness of the roadbed and pavement directly impacts the road's bearing capacity, durability, and performance. Insufficient or uneven thickness distribution can lead to premature pavement damage, such as rutting, cracking, and subsidence, seriously impacting driving safety and road life. Therefore, thickness testing is a critical technical step in road construction quality control and maintenance management.

[0003] After searching, the Chinese utility model patent with the authorization announcement number CN220602391U is a thickness detection device for roadbed earthwork construction, which includes a base, a support frame and a threaded adjustment handwheel. The support frame is fixedly installed on the upper surface of the base, and the upper end of the support frame is fixedly installed with an adjustment frame. The interior of the adjustment frame and near the front and rear ends are movably installed with positioning plates. The upper end of the support frame is movably embedded with a lifting plate, and the upper surface of the lifting plate is movably installed with a threaded adjustment handwheel. When it is necessary to adjust the length of the detection device, the knob of the adjustment frame is rotated, and the knob drives the rotating rod to rotate. At this time, the two positioning plates will move away from each other until the positioning rod is pulled out of the positioning hole. Then, the lifting plate can be pulled up to the required height. In this way, the height adjustment of the lifting plate can be completed quickly. When the rod rises, the sleeve can scrape off the mud adhering to its surface, and there is no need to manually clean the mud.

[0004] However, the position of the positioning hole of the device is fixed, and the height adjustment of the lifting plate is continuous. If the position where the lifting plate stops is not exactly aligned with a positioning hole, the positioning rod will not be able to be inserted, resulting in failure to fix the lifting plate. At this time, the user needs to fine-tune the position of the lifting plate to match the nearest positioning hole. This disadvantage will affect the adjustment efficiency and accuracy. In view of this, this application proposes a roadbed and pavement thickness detection device based on the above technical problems. Utility Model Content
