Offshore Bottom feed vibroflot Construction for 200000 ton channel project of harbor basin
The Bottom Feed Electrical Vibroflot Spec. | |
Rotation speed(rpm) | 1200-1800 |
Working pile diameter (mm) | 900-1200 |
System pressure(bar) | 6 |
Hopper volume(m³) | 1.2 |
Pipe diameter(mm) | DN250 |

BVEM assisted CCCC First Harbor Engineering Co., Ltd. to design and participate in the construction. The East breakwater in Caofeidian port area was reconstructed and the foundation was reinforced with discharge gravel piles at the bottom of the sea. The pile diameter was 1m and the maximum depth was 17m.
What is 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 of 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 n need a special vibroflot equipment with bottom feed system to realize.This professional equipment 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. Stone 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.
