Abstract
Description
Technical Field
[0001] The utility model discloses a road gap cutting device, belonging to the technical field of road cutting device equipment. Background Art
[0002] In the winter in the north, due to the cold weather, some substandard foundations shrink, causing cracks in the road surface. If asphalt is not poured in time, rainwater will seep into the foundation along the cracks, causing the foundation to sink due to water ingress, leading to further damage to the road surface.
[0003] At present, it mainly relies on manual pouring or semi-automatic pouring. Although pouring is done, it only pours the surface of the cracks, and sometimes pouring is not comprehensive. As vehicles wear the road surface, after a period of time, the cracks will crack again, resulting in repeated pouring, which is time-consuming, labor-intensive, increases costs, and hinders the normal passage of vehicles.
[0004] Whether pouring manually or semi-automatically, pouring only addresses the surface of the cracks, not the deeper ones. This results in vehicles wearing out the surface and causing it to crack again due to freezing. Rainwater will seep into the cracks the following summer, thus only addressing the surface problem. Currently, there are also slitting machines on the market, but they can only cut straight cracks and cannot cut curved cracks, making them inadequate for cracks of all shapes and sizes.
