[0002] After the road is opened to traffic, it will be subjected to long-term pressure from vehicles and erosion from the outdoor environment, which will cause various road surface diseases. Among them, cracks are one of the most common, most likely and earliest diseases among all types of road damage. Cracks in the road surface not only affect the appearance of the road and the comfort of driving, but also easily expand to cause structural damage to the road surface and shorten the service life of the road surface. Therefore, when cracks appear in the road surface, they need to be repaired by crack repair equipment. Such equipment can refer to patent number: 202223529944.7.

[0003] The general road pavement repair and compaction structure only performs simple compaction after the road repair is completed, which may affect the road surface repair. If the road surface cracks cannot be accurately repaired, it will cause a waste of the repair agent. Therefore, a road pavement repair and compaction structure is needed that can fully compact the repaired road surface and can accurately repair the cracks. Utility Model Content

[0013] Compared with the prior art, the utility model provides a road pavement repair and compaction structure, which has the following beneficial effects:

[0014] 1. The traditional road pavement repair and compaction structure only performs simple compaction after the road is repaired, and the accuracy of the repair of the road surface cracks is not enough. The design of the utility model controls the extension of the hydraulic cylinder to allow the scraper and the leveling roller to contact the ground after the repair agent is injected into the crack. The scraper can scrape away the excess repair agent and other debris to allow the leveling roller to level and compact the road surface, and then start the servo motor to allow the pressure plate to reciprocate and compact the repaired road surface. After double compaction, the road surface repair effect is better. The utility model uses the mobile device to allow the repair nozzle to face the road surface crack, and starts the pump body to accurately inject the repair agent in the storage box into the crack.

[0015] 2. This repair and compaction structure combines the functions of better compacting the repaired road surface and accurately repairing cracks. This repair and compaction structure pushes the push rod on the fixed plate to allow the universal wheel to drive the entire device to move freely, so that the repair nozzle can be accurately aligned with the cracks in the road surface. The shock absorber on the universal wheel can make the entire device suitable for various road conditions. This repair and compaction structure can directly observe the amount of repair agent in the storage box through the glass plate, and can be replenished through the injection port when it is insufficient.
