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Once the process has been completed, the probe is slowly withdrawn usually in stages of 12 inches.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.
The vibroflotation process can offer the following benefits:
When the process is done properly, it will reduce the possibility of differential settlements that will improve the foundation condition of the proposed structure.
It is the fastest and easiest way to improve soil when bottom layers of soil will not provide good load bearing capacity.
It is a great technology to improve harbor bottoms
On a cost-related standpoint, it helps improve thousands of cubic meters per day. It is faster than piling.
It can be done around existing structures without damaging them.
It does not harm the environment
It improves the soil strata using its own characteristic
No excavations are needed, reducing the hazards, contamination of soils and hauling material out from the site
No need to manage table water issues, neither the permits required to manage water discharge and dewatering issues.
The technique of vibroflotation can be adapted to each scenario and site
When vibroflotation is performed at a site, it will reduce the possibility of liquefaction during an earthquake
BVEM/ Vibroflotation equipment manufacturer in China
Profession
BVEM focus on vibroflotation market and formed a business platform with vibroflotation technique as core, on which there are three main business including the manufacturing and integration of vibroflotation equipment, sales and service for vibroflotation equipment and foundation improvement construction undertaking. BVEM is the largest manufacturer of electrical vibroflot in Asia and one of the authors of Chinese vibroflot manufacturing code.
BVEM· A pioneer to optimize construction of vibroflotation method
1.In 1997, the construction of the dam in the second phase of the three gorges project was carried out in the process of 30m deep throwing sand blasting
2.For the first time in 2001, the chimney foundation of the dingzhou power plant of 240m was strengthened by vibro - compaction method
3.In 2005, we developed the first integrated bottom feed vibroflot of China, the vibroflotation method began to treat the soft base of the soil whose Cu(shear strength) is less than 20KPa
4.In 2007, hydraulic vibroflot was used to handle the foundation of the pudu river power station,.This is the first time the treated depth achieved 32.7m in China
5.In 2014, the first YZ125KW hydraulic vibroflot was developed.
