Profile of Bottom Feed Vibroflotation:
As a extension of vibroflotation technique, bottom feed method created a larger range of vibroflotation application. In terms of its feature, vibroflotation can be conducted to treat the foundation in those projects even under following situation:
1. Silty or silty clay soil with undrained shearing strength less than 20Kpa
2. Underwater or offshore stone column construction
3. Projects under the strict controlling of pile diameter
4. Place where the water resource are used in limitation
5. Place where the waste water are strictly prohibit to discharge
Bottom feed method vbroflotation construction need a special vibroflot equipment with bottom feed system to realize. This professional equipment are commonly composed of :
1. Electrical or hydraulic vibroflot system ( vibroflot, damper, extension tube and electrical cabinet )
2. Feeding system ( feeding tube , damper )
3. Stock bin system ( double bin or single bin )
4. Material supply system ( lifting hopper )
5. Controlling system ( Valve controlling , air pressure controlling, material level controlling )
Due to the diversity of engineering condition, bottom feed vibroflot need to be customized for production.
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.
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.
