The Advantages of Vibroflotation

Jan 30, 2019 · Vibroflotation is a ground improvement technique used at a considerable depth that by using a powered electrically or hydraulically probe, it strengthens the soil. The vibroflotation will compact the soil making it suitable to support design loads. It involves the introduction of granular soil to form interlocking columns with surrounding soil.

Vibroflotation | Geoengineer

Keller Grundbau performed the work over a period of 10 working months. The equipment setup included the use of four 49 foot long vibrators suspended from a crane situated on a barge in order to allow for the compaction of the soil beneath 33 feet of seawater. The spacing scheme selected was a 9.8 foot by 9.8 foot center to center grid.

Vibro compaction | Keller North America

During vibro compaction, clean sand backfill is typically added at the ground surface to compensate for the decrease in soil volume from the densification process. The vibratory energy reduces the inter-granular forces between the soil particles, allowing them to move into a denser configuration, typically reaching a relative density of 70 to 85%.

Ground Improvement Methods Using Column-Type .

Types of Stone Column Construction Vibro-Replacement (Wet Top Feed) (i.e. Vibroflotation) Stone column construction using water flush. Refers to the wet, top feed process in which jetting water is used to aid the penetration of the ground by the vibrator. Due to the jetting action, part of the in-situ soil is washed to the surface. This soil is then replaced by the backfill material.

The deep vibrator plays a big role in cohesive soils improvement for construction engineering. The reason for this is that the vibrator can easily penetrate into cohesive soils without removing the soil. In the process of installation, the soil is displaced sideways – phase 1 in our diagram. Thus it inevitably becomes close to the machine.
