Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a concrete crack repairing mechanism. Background Art

[0002] With the increase in highway traffic volume, the increase in road overload and the acceleration of driving speed, most roads will develop cracks and varying degrees of damage during use, affecting the flatness of the road and driving comfort; if concrete cracks are not repaired in time, repeated rolling of vehicles will make the situation increasingly serious, cracks will develop or damage will form depressions, affecting driving safety and even causing traffic accidents, and eventually causing the roadbed to sink and the entire section of the highway to be scrapped.

[0003] Cracks and damaged areas on the road surface need to be repaired in time. In the early stages of the development of cracks in cement concrete components, for cracks that are slight, have no peeling or have slight peeling, and have a crack width of less than 3cm, they are usually repaired by manual grouting or by injecting adhesives. Manual grouting can repair surface cracks in cement concrete components, but internal cracks cannot be repaired. If the maintenance is not done properly, new cracks will appear, resulting in poor repair effects, low efficiency, high labor intensity, and is not suitable for large-scale concrete repair work. Injecting adhesives is generally carried out using a special pressure grouting device, which has a good repair effect, but this method is more cumbersome to use and has low repair efficiency.
