130KW Electrical Vibroflotation Compaction Of Cohesionless Soils Environment Friendly

Qualified and economic vibroflotation compaction construction equipment 130KW electrical vibroflot

Vibro techniques
A foundation treatment method by joint action of horizontal vibration and high pressure water to compact the loose sand layer or formed in soft soil of stone column to compose the composite foundation with original soil together.

Vibroflotation benefits
The deep vibro techniques present a very versatile ground improvement method that can be adjusted to a wide variety of ground conditions and foundation requirements. Its execution is comparatively fast even if large volumnes of soil are to be improved and subsequent structural works can follow very quickly.The soil improvement enables the contractor to utilise standard shallow footings which,in turn,leads to additional savings.
Another advantage is the environmental friendliness of vibro techniques,as natural and in situ materials are used. In addition, only a comparatively small quantity of soil is removed during the process.

Vibro compaction
Under the effect of vibration, the saturated sand soil liquefaction happen,which make the sand particles re-arranged and the soil interspace reduced.
Boring
By vibration and the flushing of water and/or air, the vibroflot penetrates to the designed depth.
Compaction
Compact the soil section by section up to the gound according to the requirements of the compaction current, compaction time and sectional compaction length.

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.
