Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road construction, and more particularly to a crack filling device for road construction. Background Art
[0002] Municipal roads will suffer from road damage after long-term use. The most common damage is cracks. Cracks in the road surface are one of the manifestations of disease. Cracks not only affect the appearance of the road surface and reduce the flatness, but also affect the service life of the entire road. Especially when the road surface cracks, rainwater will seep through the cracks into the road base, subbase and even the roadbed, which will corrode the concrete roadbed, weaken the strength of the base and soil base, accelerate the destruction of the road, and shorten the service life of the road surface. Therefore, it is necessary to promptly and appropriately deal with the cracks in the road surface.
[0003] When grouting cracks in roads, asphalt is generally used. When grouting, a nozzle is placed close to the crack and the asphalt is sprayed into the crack. However, asphalt tends to solidify after use, causing the nozzle to become clogged, which affects the service life of the grouting device. At the same time, it is inconvenient to install and replace the nozzle during cleaning and maintenance, which reduces the practicality of the grouting machine. Utility Model Content
