Description

Technical Field

[0001] The utility model belongs to the technical field of highway engineering, and particularly relates to a road thickness detection device for engineering supervision. Background Art

[0002] There are certain standards for building roads, which are one of the most important factors in determining the service life of roads. The main responsibility of the supervisor in highway projects is to strictly control the quality of road paving. In the process of laying asphalt pavement, the thickness of asphalt pavement is one of the key indicators. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. It is widely used in highway construction. After the construction of each layer of asphalt pavement is completed and when the project is handed over for inspection and use, the thickness must be tested.

[0003] A Chinese patent with publication number CN216308847U discloses a road thickness detection device for engineering supervision, including a base, on which support plates are symmetrically arranged, and a lifting platform, on the lower surface of which a measuring rod is arranged, and above the two support plates a driving mechanism for driving the lifting platform to reciprocate up and down is arranged, the driving mechanism including a threaded rod, the threaded rod is rotatably connected to the support plate, the threaded rod is provided with two sleeves, the two sleeves are connected to the lifting platform through a connecting rod, one end of the connecting rod is rotatably connected to the outer wall of the sleeve, and the other end of the connecting rod is rotatably connected to the upper surface of the lifting platform, and handles are provided at both ends of the threaded rod on the outside of the support plate.

[0004] The pavement thickness detection device in the above-mentioned prior art still has some shortcomings in the actual operation process. For example, although the measuring rod can detect the thickness of the asphalt pavement after the lifting plate is raised and lowered, the base is placed on the asphalt pavement during measurement, and the measuring rod passes through the base. Therefore, the measured value needs to be subtracted from the thickness of the base, which is very inconvenient to use. Utility Model Content
