Description

Technical Field

[0001] The invention relates to the field of asphalt road base surface damage repair, in particular to an asphalt road base surface damage repair device. Background Art

[0002] Asphalt roads are mainly built by mixing asphalt materials and mineral materials in a certain proportion, and going through a series of steps such as heating, mixing, paving, and compacting. Since the surface of asphalt roads is relatively flat, vehicles driving on asphalt roads will not experience major bumps, making the vehicle driving smooth. When vehicles are driving at high speeds, the high-flatness asphalt road surface will improve driving safety and comfort. Due to the characteristics of the asphalt road material itself, the asphalt road surface has a certain elasticity and porosity. Through these elasticities and porosity, the vibration and sound generated by the contact between the tire and the road surface can be buffered and absorbed, thereby reducing the noise during vehicle driving.

[0003] However, during the use of asphalt roads, when heavy trucks are driven on asphalt roads for a long time, the axle weight is too large, which will cause the road surface and base surface of the asphalt road to bear huge vertical pressure, and the excessive pressure will cause fatigue damage to the internal structure of the base surface, thus causing cracks in the road surface and base surface of the asphalt road. And with the repeated action of vehicle loads, the cracks will gradually expand and extend, and the acceleration, deceleration and braking of the vehicle will generate impact force, which will cause the base surface to vibrate, and the stress state inside the base surface material will change due to the impact force of the vibration. When the stress exceeds the tensile strength of the material itself, cracks will occur, and after the cracks are generated, the cracks need to be repaired to prevent the cracks from continuing to expand. When repairing the asphalt road base surface, a repair device is usually used to inject melted asphalt into the cracks and compact the injected asphalt.

[0004] During the use of the repair device, the melted asphalt is usually added to a heatable storage box, and then the melted asphalt is transported to the injection pipe through a delivery pump, and the melted asphalt is transported to the crack through the injection pipe, and then the injected asphalt is compressed by a compaction mechanism so that the asphalt can fully enter the crack.

[0005] However, during the use of the repair device, it will be affected by external factors. For example, strong self-heating wind will appear during the pouring process. The strong self-heating wind will disrupt the normal spreading and pouring of the repair material. Mainly, strong wind will blow away the freshly spread asphalt, resulting in the asphalt being unable to be evenly distributed on the damaged base surface, which will lead to waste of asphalt and a decrease in the quality of pouring. Secondly, strong natural wind will accelerate the heat dissipation of asphalt, causing the asphalt to solidify prematurely. This situation is particularly obvious in low temperature environments. The solidified asphalt is difficult to be compacted by compaction equipment, resulting in insufficient compaction strength and durability of the repaired road surface, and dents and cracks are likely to occur during subsequent use. Based on the above problems, the present application proposes a device for repairing damaged asphalt road base surfaces. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a device for repairing damaged asphalt road base surface, which has the advantages of ensuring the uniformity of asphalt filling, ensuring the quality of asphalt road repair, and avoiding the occurrence of dents and cracks on the repaired asphalt road base surface in a short time.
