Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance equipment, in particular to a cutting device for road cracks. Background Art

[0002] The road surface cracks during long-term use. When the asphalt surface layer is laid on the old cement road surface, the reflection effect of the joints of the original cement road surface may cause reflection cracks in the asphalt surface layer. In addition, load cracks are also a common problem of asphalt pavement, which is mainly caused by cracks in the road base.

[0003] The treatment of cracks on roads is an important part of road maintenance. The main purpose is to prevent moisture from penetrating into the roadbed and base through the cracks, causing further expansion of road diseases, while improving the flatness of the road surface and driving comfort. When the depth and width of road cracks reach a certain level, grooving and grouting are required. During the treatment, the cracks are first widened and cleaned, then filled with cold-mix asphalt mixture or hot-mix asphalt mixture, and finally compacted. Due to the variety of crack shapes, when cutting surface cracks, existing equipment cannot effectively cut quickly along the cracks. On the one hand, the cutting efficiency is low, and on the other hand, it may cause additional damage to the uncracked roads around the cracks, which is not only not conducive to subsequent repairs, but may also aggravate the expansion of the cracks.

Impurities can be sucked into the collection box through the second dust hood, and the dust generated by the cutting wheel cutting the ground can be collected by the first dust hood, and the dust can be sucked into the collection box to prevent dust impurities from polluting the environment, thereby further improving practicality.
