en.Wedoany.com Reported - On April 22, with the blasting of the final rock section, the diversion tunnel of the upper reservoir at the Jiangxi Ganzian Pumped Storage Power Station was safely completed 8 days ahead of schedule. This progress has created favorable conditions for subsequent main works.

The station is a key energy project under China's "14th Five-Year Plan." Upon completion, it will stabilize power supply, drive employment, and enhance flood control and supply security capabilities, contributing to the optimization of the energy structure.

The diversion tunnel, with a total length of 672.38 meters, features a narrow cross-section and complex geology, preventing the entry of large equipment. Construction adopted a "narrow tunnel operation" model using manual labor combined with small machinery, resulting in limited efficiency.

Facing these challenges, the project department established a technical breakthrough team. By leveraging geological forecasting to dynamically optimize the plan, strictly implementing measures such as "short drill rounds, light blasting, and strong support," and operating under a 24-hour shift system to overcome the impacts of the rainy season, they ultimately ensured the timely completion of the diversion tunnel.

The next steps involve transitioning to subsequent works, such as tunnel lining, to fully ensure project performance.
