Description

Technical Field

[0001] The utility model belongs to the technical field of road surface bearing capacity detection, and in particular relates to a highway bearing capacity detection device. Background Art

[0002] The drop-hammer deflectometer generates a corresponding equivalent load by the free fall of a drop-hammer of a certain weight. The deflection generated by this loading method is very similar to the effect of a moving vehicle on the ground, and dynamic deflection basin data can be obtained. By placing the drop-hammer deflectometer on a trailer, the drop-hammer deflectometer can be moved at will, which is convenient for road surface inspection at different locations. However, when the drop-hammer deflectometer is inspecting the road surface, the road surface should be clean and free of dust, debris or other pollutants. Once obstacles such as fallen leaves appear on the road surface, the detection data will be inaccurate. The existing solution usually involves manually cleaning the road surface to be inspected in advance and then inspecting the location to be inspected. This method not only requires the cooperation of a large number of staff, but also, obstacles are likely to appear again in the fishing area to be inspected during the interval between cleaning and inspection, affecting the detection results.
