Different types of hydraulic vibration piling hammers are suitable for different geological environments. The traditional hydraulic vibratory hammer has large amplitude and is suitable for construction on cohesive soil. The high-frequency vibratory hammer is suitable for sandy soil, and the non-resonant hammer is suitable for vibration. There are strict regional restrictions. By using a series of hydraulic vibration hammers, it is possible to settle and pull out pipe piles, high-strength concrete precast pipe piles, vibration sinking pipe piles and various steel piles.

Introduction to the operating principle of hydraulic piling hammer:

The hydraulic piling hammer uses its high-frequency vibration to vibrate the pile body at a high speed, and transmits the vertical vibration generated by the machine to the pile body, which causes the soil structure around the pile body to change due to vibration, and the strength decreases. The friction resistance between the body and the ground is then sunk into the soil by the vibratory piling and the dead weight of the pile body. When the pile is pulled out, the pile body is pulled up under high-frequency vibration. When the vibratory pile is driven, it sinks too slowly if the soil is hard. , The boom can be used to sink under pressure or raise the pile by about 0.5-1.1 meters, and then quickly flush down again.

The excitation force required by the piling machinery should be determined comprehensively according to the soil layer, soil quality, water content and the type and structure of the pile. Generally, 100-400KN vibration method is used for higher efficiency. It is mainly suitable for U-shaped steel sheet piles and I-shaped steel sheets. Piles, Larsen piles, steel pipe piles and cement precast piles with a length of less than 10M. This piling method is suitable for sandy soil operations, and the operation effect in clay is poor. At this time, if necessary, choose our company's more powerful Hydraulic pile hammer models,

The vibratory piling process of the hydraulic piling hammer is: lifting the pile-inspection-verticality-lowering the pile machine and slowly sinking it into the soil to a certain depth (if necessary, install the pile cap)-checking the pile position and axis-vibration sinking Pile to design depth-move the pile driver to the next pile to continue working.
