Vibro Compaction method


This method allows granular soils to be compacted. This method is only used to compact sandy soils.


How Vibroflotation Works


The process of vibroflotation is really simple as you will see in the following short description. The depth probe is located over the compaction point. Flushing water or air is expelled through jets in the tip of the probe. These induced injected vibrations will liquefy the soil temporarily allowing the probe a continuous penetration under its own weight.


Once the probe has reached the strata or poor soil, the water and air injections is stopped. At this point the soil is densified by the probe vibrations causing a crater around the vibrator, that should be backfilled with granular material.


Once the process has been completed, the probe is slowly withdrawn usually in stages of 12 inches. A cylindrical compaction zone is formed around the probe, and the achieved degree of compaction is indicated by an increase in oil pressure. The area around the probe is backfilled with granular material that will auto-consolidate, as the probe is begin brought up. The material used to backfill should be free of silt, gravel or crushed stone.
