Description

Technical Field

[0001] The utility model relates to the technical field of pavement repair grouting devices, in particular to a grouting device used for repairing pavement cracks. Background Art

[0002] At present, in road construction, when cracks appear on the road surface, in order to repair the cracks, construction workers usually use a grouting machine to repair the cracks. A grouting machine is a device commonly used in civil engineering and construction projects for reinforcing and repairing concrete structures. It mainly fills cavities, cracks or damaged parts by injecting specific substances, such as asphalt, concrete slurry or other materials, to enhance the strength and stability of the structure. Most of the pavement crack repair devices in the existing technology only have the grouting repair function, and are unable to remove sand, dust and gravel in the cracks. Moreover, since the amount of pavement repair work is sometimes large, the hand-pushed grouting device is large in size and heavy in weight, resulting in excessive workload. At the same time, there is no way to flatten the asphalt after repair in time, which easily causes the asphalt to solidify and accumulate. For this reason, we specially propose a grouting device for pavement crack repair. Utility Model Content
