Description

Technical Field

[0001] The utility model belongs to the technical field of highway maintenance, in particular to highway pavement maintenance and crack filling equipment. Background Art

[0002] Pavement maintenance grouting is a maintenance and repair procedure performed on roads or other hard surfaces. It typically targets cracks in the pavement. Grouting involves injecting specific materials (such as asphalt, concrete, or polymer patching materials) into cracks or gaps in the pavement to fill them, prevent moisture and debris from seeping into the roadbed, and enhance the pavement's stability and durability. This can extend the pavement's service life, reduce maintenance costs, and improve driving comfort and safety.

[0003] In the Chinese patent publication number CN220665923U, a highway pavement maintenance and grouting equipment is mentioned. This utility model sets up a grouting mechanism. When maintaining the road, the movable plate is adjusted downward by tightening the bolts so that the grouting pipe contacts the ground. Then, when the asphalt pump is turned on, the asphalt inside the storage box is extracted through the feed pipe and the bellows, so that the asphalt is output through the grouting pipe to fill the gaps on the road surface.

[0004] Although the device uses a caulking mechanism to caulk and repair cracks in the road surface, when the device is in use, the staff needs to push the entire caulking equipment to move, thereby driving the caulking pipe to move to repair the cracks. The entire caulking equipment has multiple components such as a storage tank, stored asphalt, and a mobile vehicle, which will cause the entire caulking equipment to be heavy. The cracks are generally small in diameter and curved, not a straight line. The caulking requires controlling the caulking equipment to move the caulking pipe along the direction of the cracks. The heavy weight of the caulking equipment makes it difficult to control the caulking pipe to move accurately along the cracks. It is more laborious and easily causes the asphalt discharge position of the caulking pipe to deviate, resulting in asphalt waste and reduced caulking work efficiency. Utility Model Content
