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.
vibroflot characteristics
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
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 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 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.
