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.
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 or 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.
