en.Wedoany.com Reported - The inlet/outlet gate shaft lining construction for the upper and lower reservoirs of the Langjiang Pumped Storage Power Station, operated by CSG Energy Storage in Zhaoqing, Guangdong, was recently successfully completed.

As a core structure of the power station, the inlet/outlet gate shaft bears critical functions such as flood control, flow regulation, and serves as the first line of defense for plant safety. Its construction quality directly impacts the long-term safe and stable operation of the power station. The total concrete volume for the upper and lower reservoir inlet/outlet gate shafts amounts to approximately 8,000 cubic meters. The concreting operation adhered to "high standards and strict requirements," fully leveraging technological innovation to overcome complex geological conditions and construction technical challenges. By optimizing construction methods and improving tooling and equipment, including the adoption of the one-stage direct-burial technology for guide rails and refined formwork techniques, the lining structure was ensured to be dense and smooth, with rail installation accuracy meeting specifications. This significantly enhanced construction efficiency and quality control levels while greatly shortening the construction period. During the process, the Zhaoqing project department strictly implemented a "three-inspection system" and site supervision procedures, achieving full-process quality management, thereby providing strong assurance for building a high-quality project.

With the completion of the gate shaft lining, the Zhaoqing Pumped Storage Power Station project is now advancing gate installation and commissioning work intensively to ensure the impoundment target is achieved on schedule.
