Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flattening machines, in particular to a roadbed flattening 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 the laying of tracks or roads and the operation of trains or vehicles. When the roadbed needs to be flattened, the roller, also known as a soil roller, is a road construction equipment. The roller uses the gravity of the machine itself and is suitable for various compaction operations to make the rolled layer permanently deformed and dense.
[0003] When the existing road roller is in use, it is generally rolled by a single wheel. Since the roadbed surface may be uneven due to bulges or soil piles, the single wheel road roller may easily cause potholes to form on the road surface after compaction. Therefore, we propose a roadbed flattening device to solve the above problem. Utility Model Content
