Description

Technical Field

[0001] The utility model relates to the technical field of roadbed leveling devices, in particular to a leveling device for highway roadbed engineering construction. Background Art

[0002] The highway roadbed has various cross-sections according to its filling and excavation height and the terrain it is located in. It is the main factor that determines the quality of the entire road project and affects its service life. During the roadbed construction process, the roadbed needs to be leveled. A highway roadbed construction leveling device, commonly known as a roller, is used. It is generally composed of an engine, transmission system, working device, electrical part, cab and hood. It is flexible and accurate in movement, easy to operate, and has a high degree of precision in leveling the site. It is suitable for constructing roadbeds, building slopes, flattening the ground, etc.

[0003] Although the existing leveling devices for roadbed construction are widely used, they still have some shortcomings. For example, when a roller is leveling an asphalt surface, if there are stones, branches and other debris on the asphalt surface, they will be pressed into the ground by the roller, affecting the quality of the roadbed. In addition, during the movement of the roller, some ground surfaces will have sharp protrusions, such as reserved installation bolts and screws. If the roller rolls over them, the roller's roller will be damaged. Therefore, in view of the above problems, a leveling device for highway roadbed construction is proposed. Utility Model Content
