Can you compact without a compactor? - HENGDA RIC

Use a steel handle tamper, If you're wondering if there's any simple way to compact pavers without a giant plate compactor, there is–a steel handle tamper. This is one of the most basic ways to compact your pavers. A hand tamper has the benefits of less force and impact.

The RIC compactor is mounted on a excavator so that moving around the site is easy. The compactor consists of a 7.5-ton weight falling approximately 36 inches onto an anvil in contact with the ground at a rate of approximately 40-90 blows per minute thereby compacting approximately 800 sf of area per hour. Onboard diagnostics equipment allows the compaction effort to be stopped when optimum compaction has been achieved.

RIC is a high-frequency, controlled energy, soil compaction technique used to densify surface layers of soils (to a depth of 5 to 7 meters in most cases) with minimum impact on the immediate worksite environment. Rapid Impact Compaction is widely used to densify loose granular soils (sand or gravel) as well as loam fill and industrial brownfield sites for surface compaction, foundations and floor slab support, liquefaction mitigation and waste stabilisation.

The RIC technology is the modern approach for compacting existing soils that would otherwise be excavated and compacted using a conventional roller compactor in layers of 15 to 30cm.

Energy is transferred to the underlying loose granular soils rearranging the particles into a denser formation. RIC can effectively densify up to 4-5m of soils without excavation, adding water or dewatering. It can also be used for fill compaction, which can place in bulk fill materials and compact it accordingly without adding any water.

For large infrastructure developments, RIC takes the lead due to its speed of execution that makes it much more cost effective than other alternatives.

The energy and deflection of the soil is monitored and recorded at each location, which allows the geotechnical engineer to determine when effective treatment is complete. It also enables the engineer to identify weak zones (red dots) or debris zones throughout the pad so that any remedial actions that may be required can be minimized resulting in cost savings.

The Rapid Impact Compaction technology works very well for all kinds of non-cohesive soils, especially for the compaction of gravels and sands. It can also be used on reclaimed areas where anthropogenic soils and uncompacted fills occur.

Most often, the RIC technology is used for the construction of enclosed buildings: under the foundation slabs/floors of industrial and commercial halls and under heavy surfaces of warehouses, tanks; for the construction of infrastructure: all types of roads and highways, under the road and rail embankments and often as the improvement of the base for parking lots and airport runways. A great advantage of the RIC method is its mobility and relatively small size of the equipment unit which allows for carrying out the works in areas with difficult access.
