How deep can compactor compact? - HENGDA RIC

update time:2023-02-14 16:09:19

  • 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.

A rule of thumb is that a compactor will compact 1 inch of material for every 1,000 pounds of compaction force it exerts. The latest generation HC models in the RIC range are available with drop weights of 5t, 7t, 10t and, more recently, a 16t version has been introduced. Treatment is effective in top layers typically down to 6m depth. The latest HC model, complete with a 10t drop weight, is fitted with a new sound attenuation pack which has been designed by Hangshen to significantly reduce the noise level produced by the compactor when in operation.

Most granular fills and some silts are compactable, The best results being achieved where the fill is well-graded particle size. An area of 800m² -16000m² can be covered in an average day (depending on the ‘blow-perposition’ setting.) This also allows time for routine maintenance and rotation of the special dolley pads located in the foot assembly which transfers the force of the blow through to the ground.

Use within 30 feet of a Building – Because Rapid Impact Compaction provides a low magnitude of impact loading at a very high frequency, the peak particle velocity remains relatively low (less than 2 inches per sec) at a distance of 30 feet from the source. This is different from Deep Dynamic Compaction which has a low frequency and a high magnitude of loading so vibrations are greater from DDC when compared to RIC.

Small Buildings and Floor Slabs – RIC has been used to improve soil under 2 to 3-story building footings and floor slabs.

Replace Surcharging – Instead of using a surcharge to consolidate the soil under a static weight, Rapid Impact Compaction consolidates it immediately.

Replace Over Excavation – Loose fills or soils can be consolidated immediately without the need to replace the soil.

Improve Lateral Load Capacity for Piles – The lateral load capacity of a pile is greatly influenced by the stiffness of the upper 10 feet of soil in which it is driven. By densifying the upper layers of soil the lateral capacity is greatly increased.

Rapid Impact Compactor Commissioning

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.
