Vibratory Hammer Assembly
Product Features:
1. The rotary pile driver has two built-in eccentric shafts and is driven by a hydraulic motor. The high-speed rotation generates vertical vibration force. After passing through the vibration-damping rubber, it maintains a certain amplitude and can cope with various types of soil piling requirements.
2. The excitation force is proportional to the square of the eccentric size and the number of vibrations. The eccentrics designed and produced by Shuyu Machinery have been calculated and tested in detail. They can take into account the strong excitation force and material characteristics. They can not only meet the work needs, but also ensure the improves mechanical reliability.
Construction principles and operation examples:
The rotary pile driver uses its high-frequency vibration to vibrate the pile body at high acceleration to transmit the vertical vibration generated by the machine to the pile body, causing the soil structure around the pile body to change and reduce its strength due to vibration, and the soil body around the pile body liquefies, reducing the The friction resistance between the pile and the soil is determined, and then the pile is sunk into the soil using the downward pressure of the excavator and the weight of the hammer and column.
When pulling out the pile, use the lifting force of the excavator to pull up the pile while vibrating on one side. The excitation force required by the pile driver must be comprehensively determined based on the soil layer, soil quality, moisture content, and pile type and structure.
The efficiency of vibration pile sinking is higher than other construction methods, and it is mainly suitable for Larsen steel sheet piles, steel pipe piles (casings), and cement pipe piles. This pile sinking method is most suitable for sandy soil geological operations, and has poor effect in clay soil. A model with higher power must be selected.
