Vibroflot characteristics  

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.

BVEM | vibroflot equipment manufacturer

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 larger manufacturer of electrical vibroflot in Asia and one of the authors of Chinese vibroflot manufacturing code.

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.

With 30 years experience of vibroflotation industry, BVEM researched and developed a variety of electric vibroflots motor power from 30 kw to 260 kw. BVEM’s vibroflots has complete specification model which makes widely using of range. The quality of the equipment and performance have already achieved the domestic industry leading level. Through the application of hundreds of domestic and international projects, including the Yangtze River Three Gorges Soft Ground Treatment Project, The Hong kong-Zhuhai-Macao Bridge Project, Dubai Palm Island Project,etc, BVEM has developed to be Asia's larger electrical vibroflots equipment manufacturers, and are being highly recognized by domestic and international clients.
