The advantages and applications of vibration free impact oscillating pile driver in the new era of pile driving

In modern urban construction, the development of basic construction technology is crucial for improving engineering efficiency and ensuring construction safety. With the increasing awareness of environmental protection, traditional vibrating pile hammers are limited in urban construction due to their noise and vibration pollution problems. In this context, the third generation of resonance free pile hammers has emerged. The OP series oscillating pile machine not only has the advantage of achieving efficient construction by vibrating liquefied soil through vibration pile hammers, but also avoids the difficulties of limited urban construction due to environmental issues such as noise and vibration pollution caused by vibration pile hammers. It will play an important role in future urban construction.

Development background and advantages of vibration free impact oscillating pile driver

Although traditional vibrating pile hammers have high construction efficiency, good results, and low costs, the resonance hazards generated during "start-up" and "shutdown", as well as the vibration waves generated by the inevitable up and down vibration mode of the vibrating pile hammer on the ground vibration impact, can also cause harm to surrounding buildings and affect people's lives, limiting its application in densely populated cities.

In order to overcome these limitations, the third-generation vibrating pile hammer - the vibration free impact type oscillating pile driver - has been successfully developed. It can not only vibrate liquefied soil and reduce resistance, but also control vibration noise and vibration impact, which meets the environmental protection requirements of urban construction, does not disturb residents, and ensures construction safety.

Environmental friendliness:

● Zero vibration disturbance, no disturbance to residents - Compared with traditional vibrating pile hammers, the OP series oscillating pile driver adopts a unique horizontal arc vibration method, which avoids the vibration impact on the ground caused by the vertical vibration of traditional vibrating pile hammers. The propagation of horizontal vibration waves on the ground decays faster than vertical vibration waves, greatly reducing the harm to surrounding buildings and minimizing interference with residents' daily lives.

Compared with traditional vibrating pile hammers, the measured vibration level of OP series oscillating pile drivers is only 50dB (5-meter distance), which is close to the vibration level of lifting equipment such as truck cranes and crawler cranes, achieving true vibration free construction and bringing a good working environment for urban construction.

Energy efficiency:

The innovative design of the OP series oscillating pile driver adopts an independent eccentric cavity structure, which reduces the no-load current and effectively lowers energy consumption.

● No need to overcome eccentric weight torque, low starting current, compared with traditional vibration pile drivers, the OP series oscillation pile driver can save more than 20% energy under the same pile sinking effect.

Security:

Low impact on lifting equipment and surrounding buildings: Due to the reduction of vibration impact, there is no vibration impact on lifting equipment and surrounding buildings, significantly reducing the potential harm to surrounding buildings.

Application of vibration free impact oscillating pile driver

The vibration free impact oscillating pile driver not only inherits the advantages of efficient construction of vibrating pile hammers, but also avoids the difficulties of limited urban construction due to environmental issues such as noise and vibration pollution. This device has a wide range of applications. It can not only sink and pull steel pipe piles, but also carry out construction such as pouring piles and planting piles through the double casing method. This multifunctionality and environmental friendliness make the OP series oscillating pile driver play an increasingly important role in future urban construction.
