en.Wedoany.com Reported - Nepal's Manang Marsyangdi Hydropower Station project reported on June 1 that progress has been made in the construction of Tunnel No. 3: the downstream single working face achieved a monthly advance of over 110 meters in May, with the cumulative advance of the main tunnel reaching 631 meters, surpassing the 600-meter milestone for the first time. This represents a significant improvement from the previous average monthly advance of 400 meters, setting a new project construction record.

Tunnel No. 3 has a total designed length of 1,795 meters, with a current cumulative advance of 954 meters. Based on the downstream single working face's monthly advance of 110 meters in May, it is expected that the tunnel will be fully connected by the end of the year.

During construction, the project faced multiple challenges, including unstable power supply, complex surrounding rock geology, and water seepage inside the tunnel. The project team scientifically allocated resources, optimized construction processes, and strictly implemented key control measures such as power supply assurance, drainage treatment, and surrounding rock monitoring. All construction personnel worked collaboratively in shifts, effectively improving construction efficiency while ensuring safety and quality.

This breakthrough demonstrates the project team's capability to overcome challenges and lays a solid foundation for the steady progress of the project. Moving forward, the project department will continue to closely monitor milestone targets and make every effort to ensure the project is completed on schedule with high quality.
