en.Wedoany.com Reported - The upper reservoir diversion tunnel of the Yuexi Pumped Storage Power Station in Anhui, China, recently broke through. The project is undertaken by Nanchang Branch. Representatives from the owner, supervision, design, and construction units jointly witnessed this milestone.

After the diversion tunnel breakthrough, it will serve the functions of construction diversion for the upper reservoir and flood drainage during the flood season, solving the core challenge of diversion and flood control for the main project. This creates favorable conditions for subsequent construction such as dam foundation excavation and dam filling. This milestone marks a key step in the power station construction, laying the foundation for rapid progress and timely completion of subsequent works.

Since the start of the project, the project department has coordinated procedures based on on-site geological and construction conditions, rationally allocating resources such as personnel, machinery, and materials. In response to complex geology, the technical team optimized the construction plan, strictly adhering to the construction principles of short footage, weak blasting, strong support, and frequent monitoring, refining each step of excavation and support. The project department regularly conducts safety hazard inspections and quality patrols, promptly addressing construction risks. All project personnel jointly advanced tunnel excavation, efficiently completing the breakthrough task. In the next step, the project department will take this as a new starting point, focusing on the overall construction plan, refining subsequent construction schedules, consolidating job responsibilities, strictly managing safety production, project quality, and construction progress, and orderly advancing follow-up tasks. They will strive to achieve the annual construction goals, aiming for early completion and commissioning of the project, contributing to the safe and stable operation of the Anhui power grid, the realization of regional dual-carbon targets, and the high-quality development of the local economy.
