On October 18–20, 2007, a significant academic conference was held at Nanjing Hehai University, bringing together experts and professionals in the field of water resources and hydropower engineering. In recent years, as China's economy has continued to grow rapidly, there has been a renewed surge in the development of water conservancy and hydropower projects. This growth, especially in the rapid construction of hydropower plants, has raised new challenges and higher demands for engineers and workers involved in such projects.
In response to these evolving needs, Sakai Heavy Industries Co., Ltd. introduced the world’s first vertical vibratory compactor—the SD451—designed specifically for Roller Compacted Concrete (RCC) dam construction. This innovative machine, with a compaction thickness of 1 meter, represents a major advancement in the field. At the conference, Dr. Yukimoto, Director of the Business Promotion Department at Sakai, presented the benefits and practical applications of the Japanese RCD construction method, along with detailed insights into the SD451 compaction machine.
Additionally, Sakai shared the results of a successful test project conducted last year at the Luojiahe Power Station in Dafang County, Guizhou Province. The performance of the SD451 during this trial received widespread attention from conference participants, sparking an engaging and insightful discussion among industry professionals.
This event not only highlighted the importance of modernization in water conservancy engineering but also helped enhance the visibility of Sakai Heavy Industries and its advanced compaction equipment in the Chinese market. The conference is expected to contribute significantly to the future development of the water conservancy discipline and promote the broader adoption of the SD451 vertical vibratory roller in China's infrastructure projects.
