1. Working principle
Static roller:
Principle: Rely on the weight of the roller to apply pressure to the compacted material, and use static pressure to make the material particles close together to form an overall structure with certain strength and stability.
Features: The compaction effect is relatively uniform, but the compaction depth is limited. It is mainly used to compact materials such as soil and gravel.
Vibrating roller:
Principle: Through the vibration of the vibrating wheel, the friction between the material particles is reduced, and the particles are easier to move to a tighter state, thereby achieving compaction.
Features: High vibration frequency, large compaction depth, good compaction effect, suitable for compacting materials such as asphalt and concrete.
2. Application scenarios
Static roller:
Scope of application: Mainly used for compacting soil, gravel and other materials, suitable for small projects, municipal projects and road base compaction.
Advantages: The compaction effect is relatively uniform, suitable for occasions where the compaction depth is not required.
Vibratory roller:
Scope of application: Suitable for compacting asphalt, concrete and other materials, widely used in large projects such as highways, airport runways, port terminals, etc.
Advantages: Large compaction depth, good compaction effect, suitable for occasions with high requirements for compaction quality.
3. Compaction effect
Static roller:
Compaction depth: The compaction depth is limited, usually suitable for surface compaction.
Compaction uniformity: The compaction effect is relatively uniform, but the compaction effect on deep materials is poor.
Vibratory roller:
Compaction depth: High vibration frequency, large compaction depth, can effectively compact deep materials.
Compaction uniformity: Although the vibration compaction effect is good, it may cause uneven surface of the material in some cases, and it needs to be followed up with a static roller.
4. Equipment features
Static roller:
Simple structure: The structure is relatively simple and the maintenance cost is low.
Smooth operation: Smooth operation and low noise.
Scope of application: Suitable for occasions where the compaction depth is not required.
Vibratory roller:
Complex structure: The structure is relatively complex and the maintenance cost is high.
Operation vibration: It will vibrate and make a lot of noise during operation.
Scope of application: It is suitable for occasions with high requirements for compaction quality.
5. Maintenance
Static roller:
Daily maintenance: Mainly focus on the cleaning, lubrication and tightening of the equipment.
Regular maintenance: Check the oil level regularly, replace the oil and filter.
Vibratory roller:
Daily maintenance: In addition to cleaning, lubrication and tightening, it is also necessary to check the sealing and lubrication of the vibration system.
Regular maintenance: Check the parts of the vibration system regularly, replace the worn parts, and ensure the normal operation of the vibration system.
6. Summary
Static roller: It is suitable for occasions with low requirements for compaction depth, such as small projects and road base compaction.
Vibratory roller: It is suitable for occasions with high requirements for compaction quality, such as large projects such as highways and airport runways.
7. Selection suggestions
Small projects: If the project is small and the compaction depth is not high, you can choose a static roller.
Large projects: If the project is large and has high requirements for compaction quality, it is recommended to choose a vibratory roller.
Comprehensive requirements: In some large projects, in order to achieve better compaction effects, static rollers and vibratory rollers can be used at the same time.
