Description

A compacting device for road construction

technical field

The utility model relates to the field of road construction, in particular to a compacting device for road engineering construction.

Background technique

During road construction, it is often necessary to compact the road. Road tamping refers to the process of tamping and strengthening freshly laid roads to increase the strength of the road and speed up the forming speed of the road.

Road compaction is generally carried out by road rollers (tamping devices), which can compact sandy, semi-cohesive and cohesive soils, roadbed stabilized soils and pavement layers. With the gravity of the machine itself, the road roller is suitable for various compaction operations, so that the rolled layer can be permanently deformed and compacted. Because the rollers of the road roller will adhere gravel to the roller during the process of compacting the road, when there is too much gravel attached, the gravel will easily move with the roller and may fall into the interior of the roller , friction and collision with the internal components of the roller, causing damage to the roller.
