EP1100 Three Brothers Gather in the South China Sea to Assist in the Construction of Offshore Wind Power Pile Foundations

With the rapid development of the global offshore wind power industry, offshore wind power piles have shown characteristics of super large, ultra long, overweight, and high precision. Therefore, the construction of offshore wind farms has put forward stricter requirements for engineering construction. How to make the construction of wind power pile foundations more scientific, efficient, and safe has become a key technical challenge for various pile engineering equipment manufacturers. In this context, our company's design and development of the "EP series resonance free eccentric torque stepless adjustable vibration pile hammer" provides strong support and guarantee for the construction of offshore wind power pile foundations.

Recently, I went on a business trip to Guangdong. I am fortunate to see our EP1100 non resonant vibration pile drivers, brothers 5, 7, and 9, gathered in the South China Sea to assist in the construction of offshore wind power auxiliary piles. The scene was extremely 'shocking'.

With boundless passion, some people cannot help but ask, what are the specific aspects of EP resonance free hammer? Today, the editor will help everyone solve these problems.

1. Why does a vibrating hammer need to be 'non resonant'? Does it have any practical significance?

Here, the editor would like to remind everyone to correctly distinguish between the concepts of "vibration" and "resonance". The 'vibration' referred to here is the 'beneficial' destructive force during the construction process of pile foundations. During the process of pile driving and extraction, the vibrating pile hammer utilizes the excitation force to "liquefy" and loosen the soil around the pile to reduce its size. Lateral friction resistance enables rapid pile driving and extraction operations, therefore "vibration" is a necessary condition for pile driving and extraction. Resonance "is a" harmful phenomenon "that occurs when a device must pass through a resonance zone during startup and shutdown. Not only will it generate a large amount of noise pollution, but it will also subject the equipment to additional loads, thereby affecting the vibration hammer itself and related equipment. Causing significant harm. Especially in the construction of large vibrating pile hammers, effectively avoiding this "resonance hazard" can ensure safer construction.

2. What are the energy consumption advantages of EP resonant hammers compared to ordinary vibrating hammers?

We attach great importance to energy conservation. At present, the mainstream vibration hammers on the market are driven by electricity, often using industrial electricity or generator sets as power sources. Ordinary vibrating hammers start with eccentric torque and require more power during startup. The eccentric torque of the EP hammer is infinitely adjustable. The eccentric torque can be adjusted to "zero" before starting and stopping, allowing the vibrating hammer to start and stop under "zero" excitation force, thus requiring only a small power supply and reducing the number of supporting equipment. Invest, reduce energy consumption, and truly achieve "energy-saving and cost saving".

3. What are the advantages of eccentric torque stepless adjustable technology in terms of efficiency?

A major problem faced in the construction of pile driving is the uncertainty and diversity of geological conditions, and the construction efficiency is greatly affected by changes in geological conditions. The EP series vibration hammer can infinitely adjust the eccentric torque during machine operation. The amplitude can be infinitely adjusted from "0-Max" or "Max-0". Equipped with an eccentric torque adjustment visual display module, the eccentric torque is visualized and adjusted accurately. Meet the requirements of different geological conditions for pile sinking and extraction, in order to achieve the ideal speed and efficiency of pile sinking and extraction.

4. When offshore wind power piles sink, the sea conditions are poor. How to ensure the smooth operation of the equipment?

Large vibrating hammers are commonly used for the construction of offshore wind power piles. The large-scale EP vibration pile driver adopts a horizontal structure and a beam type independent structure damping system, achieving a low center of gravity, low overall height, resonance free start stop, and easy operation. More stable.

5. Offshore wind power piles are super large, ultra long, overweight, and high-precision. How to deal with EP vibration hammer?

Offshore wind power piles have characteristics such as super large, ultra long, overweight, and high precision, often requiring ultra large pile driving equipment. At present, most of them rely on imports, which not only have high investment costs but also long cycles. Our large non resonant vibration hammer adopts multi hammer linkage technology, which can achieve synchronous rotation and eccentric torque (amplitude) adjustment of multiple hammers. Through linkage, super strong power, excitation force, and impact impulse can be generated to overcome the construction difficulties of "large piles". And due to the fact that the hook center, beam center, vibration center, and pile center are four points and one line, equipped with a verticality detector to ensure the accuracy of pile sinking, it is particularly suitable for large-scale pile foundation construction. Projects such as offshore wind power generation.

In short, the EP series resonance free eccentric torque infinitely adjustable vibration hammer is not only "safe" and "energy-saving", but also "efficient" and "stable". It is a powerful tool for pile foundation construction in the new era.
