Component of Vibroflotation system
1. 
Hanging Head
It is connected with the lifting equipment and installed at the top
of the vibroflotation system, which is an important part to ensure
the safe construction of the whole vibroflotation system. The
supporting curved beam plays the role of supporting and protecting
the cable and water pipe.
Guiding role in pile making process. Cables and water pipes pass
through them. During construction, when the water demand is large,
it can be directly used as a water pipe. Increase or decrease the
number and length of extension tubes to meet the requirements of
pile making depth in construction.
It belongs to vulnerable parts. Eliminate the impact of vibration
of the extension tube ( part2) and its accessories on the vibroflot
during construction.
Submersible motor for vibroflotation device. It drives the
eccentric block in the vibration body(part 5) to rotate through the
main shaft.
Eccentric block is included. After the motor rotates, the
horizontal vibration force is transmitted to the surrounding soil
layer to compact the collapsed soil or additional materials into
piles
BVEM vibroflot equipment project case
Vibroflotation Stone Column Pile Reinforcement Project of fish pond
revetment
On July 4, 2022, the Vibroflotation Gravel Pile Reinforcement
Project of the Bay Longbei fish pond revetment below an elevation
of 305 meters undertaken by Beijing vibroflotation Engineering
Machinery Co., Ltd. Vibroflotation Gravel Pile and plastic concrete
cut-off wall project were successfully completed.
By adding two rows of Vibroflotation Gravel Piles on both sides of
the central axis of the dam (the main position of the cut-off
wall), it not only highlights the pervious consolidation function
of Vibroflotation Gravel Piles, but also deals with the
liquefaction of the backfill foundation, increases the compactness
of the dam body, and increases the lateral shear resistance of the
soil mass, so that the backfill layer of the dam body can reach the
pre settlement of the soil mass around the cut-off wall before the
construction of the cut-off wall. At the same time, Vibroflotation
Gravel Piles reduce the damage of external forces to the
anti-seepage wall, reduce the pressure on the wall, make the dam
more stable, and the flexible anti-seepage effect of plastic
concrete anti-seepage wall is more prominent.
The total work quantity of the project is 10694.69 meters. In the
treatment of Vibroflotation Gravel Piles, our company uses 75kW
vibroflotation equipment for operation. The average depth is 13.3
meters, the pile diameter is 0.8 meters, the pile spacing is 2.0
meters, and the pile layout form is rectangular pile layout. Adopt
stones with particle size of 0.5-0.7 cm and saturated compressive
strength greater than 85mpa, and the bearing capacity of the
treated foundation FAK ≥ 150kPa.
