DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1The utility model provides a technical solution: a weather-resistant and anti-skid colored pavement repair structure, comprising a concrete base 1 to be repaired, the thickness of the concrete base 1 is 40-150mm; a colored anti-skid pavement bonding slurry layer 3 and an anti-skid aggregate layer 4 are sequentially arranged on the upper surface of the concrete base 1, wherein the thickness of the colored anti-skid pavement bonding slurry layer 3 is 0.5-2mm, and a primer 2 is arranged between the colored anti-skid pavement bonding slurry layer 3 and the concrete base 1, and the primer 2 is preferably a concrete repair agent layer. After the surface of the concrete base 1 to be repaired is cleaned and polished, the primer 2 is sprayed on the upper surface of the concrete base 1 using an electric sprayer to perform a sealing and reinforcement treatment of the primer, and after the primer 2 is dried, the colored anti-skid pavement bonding slurry layer 3 is evenly scraped on the primer 2, and the colored anti-skid pavement bonding slurry layer 3 can be a commonly used pigmented epoxy resin.

[0017] The base coat 2 improves the bonding strength between the colored anti-skid pavement bonding slurry layer 3 and the concrete base layer 1, thereby ensuring the overall bonding firmness of the repaired structure, avoiding cracks or even fragments in the repaired pavement structure due to vehicle rolling during long-term use, extending the service life of the anti-skid pavement and ensuring the travel safety of vehicles and pedestrians.

[0018] After the colored anti-skid pavement bonding slurry layer 3 is scraped and smoothed, the anti-skid aggregate layer 4 is evenly spread on the upper surface of the colored anti-skid pavement bonding slurry layer 3. The anti-skid aggregate layer 4 can be selected from colored ceramic particles, artificial colored sand, quartz sand, wollastonite, crushed stone, etc.

[0019] The upper surface of the anti-skid aggregate layer 4 is also provided with a surface coating layer 5. After the anti-skid aggregate layer 4 is spread, when the road surface is in the initial setting state, an electric sprayer is used to spray the surface coating layer 5. The surface coating layer 5 is preferably a concrete repair agent layer. The road surface is covered and maintained through the surface coating layer 5, and the maintenance requirement is 4-6 times within 24 hours.

[0020] A colored weather-resistant surface layer 6 is arranged on the upper surface of the surface coating layer 5. The thickness of the colored weather-resistant surface layer 6 is 0.5-1.2mm.

[0024] A further preferred technical solution is that a plurality of drainage holes 9 are evenly opened at the edge of the concrete base layer 1, and the drainage holes 9 are connected to the drainage pipe 10. The accumulated water that seeps into the road surface through the drainage trough 8 enters the drainage pipe 10 through the drainage holes 9, and is then discharged from the drainage pipe 10 to the drainage system connected thereto, thereby completing the rapid discharge of the accumulated water on the road surface and avoiding various problems caused by the accumulation of water.
