Technical Field

[0001] The utility model relates to the technical field of roadbed compaction, in particular to a highway roadbed compaction device. Background Art

[0002] The roadbed is the foundation of the track or road surface, and is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track and locomotive vehicles or road surface and traffic loads, while transmitting and diffusing the loads deep into the foundation. In highway engineering, the roadbed occupies an important position in terms of construction quantity, land area and investment.

[0003] The roadbed is not a stable and solid structure in the early stage and needs to be compacted manually. The roadbed is compacted by operating a road surface compactor to strengthen the stability of the roadbed.

In addition, most of the devices are large in size and heavy in weight, which are not easy to use and are not easy to move. Therefore, a roadbed compaction equipment is needed to improve the above problems. Utility Model Content
