Description

Technical Field

[0002] With the continuous development of the transportation industry, the frequency and load of road use are increasing, and the problem of road damage is becoming more and more prominent. The traditional method of repairing road damage mainly relies on manual operation, which has many disadvantages. Therefore, some new road damage repair devices and repair methods have appeared on the market.

[0003] For example, the Chinese patent with the publication number CN110700062A discloses a road repair device and repair method, including a vertical shaft, a spiral blade, a flat plate, a vertical scraper and a scraping needle, which can improve the bonding degree between multiple layers. The method is: 1. Rotate the spiral blade on the vertical shaft to the downward position, and the rotation of the vertical shaft drives the spiral blade to rotate. When the spiral blade rotates and moves downward, the damaged road surface is damaged, and a pit of appropriate size is dug at the damaged position of the road; 2. Install the discharge box on the vertical scraper, and the discharge box will always move with the vertical scraper. The asphalt mixed with stones falls down, and the rotation of the vertical shaft drives the vertical scraper to rotate to flatten the asphalt mixed with stones; 3. Move multiple scraping needles downward. At this time, when the vertical scraper moves, multiple scraping needles can scratch marks on the flattened asphalt; 4. When repairing, it is necessary to spread the asphalt mixed with stones into the pit in layers, and after the lower layer solidifies, spread the asphalt mixed with stones on it; 5. The roller is used to finally flatten the uppermost surface of the repair.

[0040] like Fig.16 As shown: A road damage repair method, the specific steps of the repair method are as follows: S100, inspect the damaged area of ​​the road. When inspecting the damaged area, it is necessary to use detection equipment, such as ground penetrating radar, to accurately inspect the damaged area of ​​the road and determine the scope and depth of the damage. After determining the damaged area of ​​the road, clean and sweep the area, and use a vacuum cleaner 6 to clean the dust particles in the area to ensure that the surface of the repair area is flat and dry.

[0041] S200. Reinforce the base layer in severely damaged areas to improve its bearing capacity.

[0042] S210. Clean all gaps in the severely damaged areas, and then inject high-strength bonding materials into each gap.

[0043] S220. After the high-strength adhesive material solidifies, a layer of reinforcing material is laid on the surface of the base layer, and the high-strength adhesive material is injected between the reinforcing material and the base layer.

[0044] S230, prepare a repair slurry, and spread the repair slurry on the reinforcing material on the surface of the base layer.

[0045] S300, road damage repair materials and water are poured into a mixing box 2 according to a certain ratio and stirred to form a repair slurry. During the mixing, various materials are mixed according to a certain ratio and prepared into a uniform repair material under specific temperature and stirring conditions. This repair material has good adhesion, durability and crack resistance.

[0046] S400, the repair slurry is drawn out of the mixing drum by the screw conveyor 4 and discharged to the area to be repaired, and then the repair slurry is spread flat. When the repair area is deep, the repair area needs to be repaired in layers.
