en.Wedoany.com Reported - On March 23, the guide shaft for the ventilation shaft of the water diversion and power generation system at the Mengdigou Hydropower Station in Sichuan Province, China, was successfully completed, providing crucial support for the subsequent shaft enlargement excavation. This guide shaft has a diameter of 3 meters and a total length of 157.5 meters. The designed total diameter of the ventilation shaft reaches 7.3 meters, making it a large-diameter, ultra-deep shaft structure that plays a key role in the project construction.

As a critical passage for the water diversion and power generation system, the ventilation shaft is responsible for continuously supplying fresh air and effectively exhausting harmful gases, heat, and humidity during the powerhouse construction and future operation and maintenance, ensuring a safe working environment. The completion of the guide shaft not only opens up the core construction path but also improves ventilation conditions for the subsequent enlargement excavation phase, enhances muck removal efficiency, and secures the project schedule.

Moving forward, the project will fully enter the stage of guide shaft enlargement excavation and lining construction. The construction team will continue to focus on milestone targets, strictly control safety and quality, and drive the early commissioning and power generation of the Mengdigou Hydropower Station, contributing to the regional energy supply.
