450mm 260kW vibroflotation compaction pile driver enhancing the seismic capacity

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.

• Extension Tube

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.

• Vibration damper

It belongs to vulnerable parts. Eliminate the impact of vibration of the extension tube ( part2) and its accessories on the vibroflot during construction.

• Motor

Submersible motor for vibroflotation device. It drives the eccentric block in the vibration body(part 5) to rotate through the main shaft.

• Vibration body

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

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.
