What is a vibrating roller
Vibrating road roller is a heavy construction machinery widely used in infrastructure construction such as highways, railways, airports, and ports. It is mainly used to compact soil, asphalt concrete, sand and gravel and other materials to improve the compactness and stability of the foundation. Its core working principle is to transmit impact force to the ground through the rapid vibration of the vibrating wheel, thereby achieving efficient compaction.
In recent years, with the rapid development of infrastructure construction, vibration rollers have become more and more widely used in the engineering field. The following are the hot topics and hot contents of the entire network on vibrating rollers in the past 10 days:
1. Classification of vibrating rollers
According to different working methods and structural characteristics, vibrating rollers can be divided into the following categories:
| type | Features | Applicable scenarios |
|---|---|---|
| Single steel wheel vibration roller | The front wheel is a vibrating wheel and the rear wheel is a driving wheel, which has strong compaction capability | Finishing of foundation layers such as soil, sand and gravel |
| Double steel wheel vibration roller | Both front and rear wheels are vibrating wheels, and the compaction effect is even | Compacting of asphalt concrete pavement |
| Tire roller | Use pneumatic tires and compacted by static pressure | Final pressure and repair of asphalt pavement |
| Small vibration roller | Small size, flexible operation, suitable for narrow spaces | Small projects such as sidewalks and trenches |
2. Working principle of vibrating roller
The vibrating roller generates impact force through the rapid vibration of the vibrating wheel, compressing the gap between the material particles, thereby improving the density. Its core components include vibration wheels, engines, hydraulic systems and control systems. The following are the main operating parameters of the vibration roller:
| parameter | illustrate | Typical values |
|---|---|---|
| Vibration frequency | The number of vibrations of the vibration wheel per minute | 25-50 Hz |
| amplitude | Vibration amplitude of the vibration wheel | 0.5-2.0 mm |
| Work weight | Total weight of the roller | 1-20 tons |
| Driving speed | The working speed of the roller | 2-10 km/h |
3. Advantages of vibrating rollers
Vibrating rollers have the following significant advantages over traditional static rollers:
-High compaction efficiency: Vibrating roller can quickly achieve the required compactness through vibration impact force, saving construction time.
-Wide scope of application: Whether it is soil, sand, gravel or asphalt concrete, the vibrating roller can effectively compact it.
-Energy-saving and environmental protection: Modern vibrating rollers adopt high-efficiency engines and hydraulic systems, reducing fuel consumption and emissions.
-Flexible operation: Some models are equipped with intelligent control systems, which are easy to operate and adapt to complex working conditions.
