Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge engineering construction, in particular to a tamping device. Background Art

[0002] The reason why the concrete roadbed needs to be compacted is to ensure the overall stability of the roadbed. If the foundation below the roadbed cannot withstand the settlement caused by traffic load, it will cause the road surface to collapse and crack, further affecting the normal use of the road. Therefore, for concrete roads, compaction of the roadbed is particularly important.

[0003] When the existing tamping device encounters sticky soil, a large amount of mud will be attached to the tamping roller, which is usually scraped off manually. The operation is laborious and the scraping effect is poor. In addition, there are many potholes and bumps on the road surface that require manual assistance to level. The leveling process is troublesome and greatly increases the labor intensity of workers. Utility Model Content
