Stone Column Construction Bottom Feed Vibroflot Cohesive Soil Improvement

High performance electrical bottom feed vibroflot used for dry method stone column construction

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.

Vibro replacement
Jet water and vibrate by vibroflot to form holes. Fill in pile holes by section with solid filling materials such as gravel (cobble) etc., to finally form composited foundation.
Boring
By vibration and the flushing of water and/or air, the vibroflot penetrates to the designed depth.
Backfill
Fill stones into the bore-hole, and compact section by section up to the ground according to the requirements of compaction current and the sectional compaction length.

Profile of Bottom Feed Vibroflotation:

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.
