vibroflot characteristics
The vibroflot barrel and the motor housing are made of high strength forged steel
The motor coil adopts high temperature aging film envelop, long service life and good insulation effect
Unique circulating water cooled motor structure, good heat dissipation with high efficiency
Both vibroflot and motor are imported with FAG original bearing
Double-deck vibrating head design with good resistance, easy to replace
Unique bearing oil lubrication, further improve bearing life
Vibroflotation Technique
Loose soil or fill can be compacted at depth through insertion of vibrating probes together with a large volume of water to generate localised liquefaction of the soil. This enables the particles to rearrange themselves in a denser formation and thus increases the overall density of the soil.
Advantages
The use of a vibrating probe makes it possible to reach large depths compared to compaction carried out at the surface (dynamic, rapid impact). Vibrocompaction relies on overburden pressure of soils above the treatment level (included collapse) therefore it is not very effective in the top two metres of soil generally due to a lack of vertical confinement.
Applications
This technique is usually employed to stabilise or treat hydraulic fill, for example to prevent liquefaction or limit thrust behind quay walls.
FAQ
What settlement is to be expected during works?
The initial trial area defines the value precisely, but as a general rule, vibrocompaction of fill placed hydraulically generates settlement amounting to 7 to 10% of the height of the soil treated.
