  • 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.

RIC is a process where loose subsurface soils are improved using an excavator-mounted 7.5 ton hydraulic hammer. The hammer is rapidly raised and lowered onto a 1m diameter plate, which densifies the soil, in-place, without the need for undercut and replace. The average compaction point is hit 30-80 per minute.

Rapid Impact Compaction (RIC) is a ground improvement technique that densifies shallow, loose and, granular soils. Soil treated by this method results in increased density, friction angle, and overall stiffness, which results in increased bearing capacity and decreased settlement of planned structures. Rapid Impact Compaction consists of an excavator-mounted, hydraulic pile-driving hammer repeatedly striking a circular plate that rests on the ground.  Energy is then transferred to the ground safely and efficiently, as the RIC’s foot remains in contact with the ground, which avoids concern over flying debris being ejected. Rapid Impact Compaction densifies loose-fill soils of up to 6 m deep or more. Additional benefits of rapid compaction include: an increase of the bearing capacity of the soils, minimization of settlement, and the creation of uniform support for foundation footing. Rapid Impact Compaction is an innovative solution when compared to the time and cost of over-excavation and re-compaction.

The RIC machine consists mainly of three components: a crawler hydraulic excavator base with a strengthened arm to which a compaction hammer is attached. A weight within the hammer generates compression by the repeated drop onto a compaction foot that remains in contact with the ground.

RIC is an acronym that stands for Rapid Impact Compaction. It involves a machine, an excavator, a 50 tonne excavator, that has a purpose-built attachment that undertakes what is called Rapid Impact Compaction. Its purpose is to, basically compact loose materials in the ground underneath where we are trying to build the road.
