BVEM Bottom Feed Vibro float Equipment Vibroflotation Technique for Compacting Soil Ground

Bottom feed vibroflot system China manufacturer--Beijing Vibroflotation Engineering Machinery Co.,Ltd (BVEM)

The Bottom Feed vibro-replacement is a special method realized by using BOTTOM FEED VIBROFLOTATION DEVICE, which can fill the stones from the outlet located at the bottom of the vibroflot. It mainly used for under water vibroflotation construction or silt clay soil improvement with non-drainage shear strength less than 20kpa.

Construction process

Drawn by crane, the vibroflot works with high pressure water and air, penetrates the soil layer until to the specified depth, and then the valve of the bypass tube of the vibroflot is opened to fill stone from bottom of borehole. When the stone material amount achieve the need for this depth, the valve is closed.A certain distance is raised on the vibroflot, the material valve is re-opened, and the stone material is released, meanwile the current position, electrical current, filling amount and depth are recorded by the monitor. Repeat the above process until the vibroflot is completely lift out of the ground, when a pile is completed.

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

• Underwater or offshore stone column construction
• Projects under the strict controlling of pile diameter
• Place where the water resource are used in limitation
• Place where the waste water are strictly prohibit to discharge

Our company is executing a construction of bottom feed vibroflotation in Timor-Leste Tibar Bay Port New Container project. Both Land construction and Offshore construction are included in it. Following pictures are the aerial view of this project. You can find the detail of bottom feed vibroflotation application in the attached files.
