The Phase I project of the Fodu Operation Area plansto build 2 container berths of 200,000-ton class，with a total land area of approximately 931,400 square meters，of which the ground treatment area accounts for more than 80%.
The project's geological conditions are complex, with local silt layers as thick as more than 40 meters, a pile diameter of 1 meter, and a maximum pile driving depth of about 40 meters, placing extremely high demands on the equipment's penetration capability and continuous operation stability.

Under these conditions, the EP550B, with its large eccentric moment, powerful vibration impulse, and stable product performance, achieves rapid pile driving. At present, 4 EP550B units are operating simultaneously; whether driving or extracting piles, they maintain efficient and stable operation under long-duration, high-frequency working conditions, providing reliable validation for the subsequent large-area ground treatment.

The EP550B is specially designed for stone column and sand compaction pile methods, with several key advantages:

The Fodu project is an important project in Zhejiang Province's advancement of the "Strong Port Strategy" and the "Ningbo-Zhoushan Integration" strategy.
The stable performance of the EP550B provides strong support for Ningbo Zhoushan Port, a world-class port hub.

From every startup of the vibratory hammer to every line of recorded data-driven construction, these are true footnotes to "Chinese Manufacturing"—
safety, power, reliability.

This is not only Zhenzhong's product conviction, but also the confidence of Chinese equipment going global.
