130kW vibroflotation equipment in construction of Karnaphuli River Tunnel in Chittagong, Bangladesh

Vibroflotation construction

On February 19, 2022, the Vibroflotation Stone Column Pile Construction of S2 section of kanapuri River Tunnel in Chittagong, Bangladesh, which lasted for three months, was successfully completed. The total work quantity of the project is 13483 linear meters, and the gravel pile with 130kW vibroflotation equipment produced by bvem is adopted. The construction pile diameter is 1m, and the deepest pile depth is 24.5m.

Vibroflot profile

As a pile driving machine, vibroflot is a typical equipment with big population, high efficiency and better economy.
The working principle of the vibrator is that the special motor mobilizes the eccentric block within the vibrating body through coupling, generating centrifugal force, and causing horizontal vibration of the whole vibrator. The vibrator can be applied in the construction of packing vibro pile and compaction vibro pile. It is applicable for the consolidation of foundations such as gravelly soil, sandy soil, silt soil, cohesive soil, artificial soil and collapsible soil etc., as well as increasing density and resisting liquefaction of various types of liquefiable soil. After vibration shock process, the stratum can stand a certain degree of dynamic load, and can improve bearing capacity of foundation soil, relative density and liquefaction resistance capacity.

• The vibroflot barrel and the motor housing are made of high strength forged steel
• The motor coil adopts high temperature aging film envelop, long service life and good insulation effect
• Unique circulating water cooled motor structure, good heat dissipation with high efficiency
• Both vibroflot and motor are imported with FAG original bearing
• Double-deck vibrating head design with good resistance, easy to replace
• Unique bearing oil lubrication, further improve bearing life

BVEM focus on vibroflotation industry for more than forty years, we have largest production line for vibroflot and accessories in China and we are also the chief-editor of China electrical deep vibrator manufacture standard.

We have developed vibroflots cover powers from 30kW-260kW, can treat most kinds of foundations with different soil layer.

Also we are first manufacturer that produce complete set of bottom feed vibroflot
