  • There are many construction projects for rapid impact compaction machine, among which HC84 rapid impact compaction machine participated in the construction of Hong Kong International Airport and Xiamen International Airport. HC150 participated in the construction of Jizan airport in Saudi Arabia and China Jinan Yaoqiang Airport and Dubai Airport, United Arab Emirates. HC36 and HC42 rapid impact compactors participated in the construction of major highways in China and Yangshan Port in Shanghai.

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.

Depending on the soil type, water conditions and parameters of the hammer the soil compaction range reaches a depth between 4.0 and 5.0 m.

Rapid Impact Compaction is a shallow ground improvement and densification technique. This method densifies shallow, granular soils, which repeatedly strike an impact plate on the ground surface using a hydraulic hammer. The energy is transferred to the underlying loose soils and regroups the particles into a denser formation. The impact locations are located on a grid pattern and the spacing of those locations is calculated by the subsurface conditions and foundation loading and geometry.

Advantages of Rapid impact compaction:

The bearing capacity of the soil is increased after it is treated.

Minimizes settlement to a greater extent and provides uniform support for a floor slab or foundation footing, while controlling vibrations to 2 inches per second within 30 feet of the drop point.

Rapid Impact Compaction consolidates the soil immediately instead of using a surcharge to consolidate the soil under a static weight.

Loose fills or soils can be consolidated immediately without the need to replace the soil.

When the soil is treated by Rapid impact compaction, the stiffness of the upper 10 feet of soil affects the lateral load capacity of a pile. By densifying the upper layers, the lateral load capacity is greatly increased.
