Vibroflotation method
Under the joint action of the horizontal vibration of the vibroflot and high pressure water or air, the loose foundation is compacted; or after forming holes in the foundation layer ,the hard coarse particle materials is backfilled to form reinforcement body. Then, composite foundation will be formed by reinforcement and surrounding foundation soil.
The product is widely used in foundation treatment projects such as the hydropower industry, petrochemical industry, port terminals, thermal power generation, airport renovation and expansion, and civil buildings.
Component of Complete Set of Vibroflot
1. Hanging Head
A key part to guarantee the safety construction of the whole vibroflot. It should be installed at the top of the vibroflot and can be connected with the crane hook
2. Extension Tube
Used for protecting the cable and water pipe. It also can be used directly as a water pipe when the demand of water supplying is large.
3. Vibration Damper
Reduce the impact of vibration
4. Motor
Used to drive eccentric block rotation of vibroflot
5. Vibration Body
Transmit horizontal vibration force, impact soil, and from into compacted pile body through feeding or compaction effect
Composition of vibroflotation construction equipment
Vibroflotation
vibroflotation is one of a typical technique which is a widely used application for foundation soil
improvement. In vibroflotation construction, vibroflot equipment makes a joint action of horizontal
vibration and high pressure water or air shock to compact the loose sand layer or formed in soft soil
of gravel column to compose the composite foundation with original soil together, finally achieve the
improvement of soil by load capacity, settlement controlling as well as the anti-seismic capacity.
Vibroflotation is often used in foundation treatment of dams, oil fields, power plants, ports, airports,
bridges, etc.
Vibro techniques
The depth vibrator is used for 2 distinct techniques which differ both in their soil improvement and in
their load transfer mechanism. They are Vibro Compaction technique and Vibro Replacement technique.
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.
