Description

Technical Field

[0001] The utility model relates to the field of road surface maintenance, in particular to a road surface crack filling device. Background Art

[0002] Pavement maintenance refers to a series of work that involves regular inspection, maintenance, and repair of the road surface, aiming to extend the service life of the road, improve traffic safety, and ensure driving comfort. Pavement maintenance is an important measure to ensure safe, smooth, and long-term use of roads. It needs to be carried out regularly, and effective measures must be taken to keep the road surface in good condition. Cracks on the road surface will be sealed with special materials to prevent crack expansion and reduce water infiltration, thereby extending the service life of the road surface. When repairing pavement cracks, a pavement crack filling device will be used to repair the road surface.

[0003] Traditional pavement crack filling devices usually use concrete to fill cracks in the pavement. After the pavement cracks are filled, the concrete is mostly naturally dried. During the natural drying process, the concrete is compacted by traffic and vehicles before it is fully dried, which will cause deformation, cracking or settlement in the filled area, reducing the quality and durability of the repair. Additional maintenance and repair work is required to correct the problems caused by wet concrete, which will increase maintenance costs and workload.

[0004] Therefore, it is necessary to provide a new pavement crack filling device to solve the above technical problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The pavement crack filling device first pours concrete raw materials into a mixing barrel in sequence, and then mixes the concrete raw materials through a stirring assembly.
