Qilian snow reflects thousands of peaks, tunnels through clouds open new Vientians
recently, the two key channels of
Gansu Huangcheng pumped storage power station
connected on the same day
marked the smooth flow of the "lifeline" of the upper reservoir construction of the power station
the project construction has officially entered the full construction stage of the main project!
Gansu Huangcheng Pumped Storage Power Station has successfully completed the traffic hole 11 days in advance, the construction adit of the upper and lower section of the diversion tunnel of the power station and the tunnel of the connecting road of the upper and lower depots will be completed simultaneously on the same day.
The two channels connected this time are the core of the power station construction, shouldering the dual key missions of construction organization and promotion and large material transportation. Among them, the No. 1 construction adit has a total length of 861.2 meters and a maximum section size of 10.48 × 10.01 meters, which is the only way to enter the upper section of the diversion tunnel; the No. 2 upper and lower reservoir connecting road tunnel has a total length of 1139 meters and a maximum section size of 10.03 × 8.7 meters, which is an important transportation hub connecting the upper and lower reservoirs of the power station.
during the construction process, the participating teams need to face the severe test brought by geological conditions. Among them, the tunnel section with a length of more than 970 meters belongs to Class IV and V surrounding rock, and the construction risk is significant and the difficulty is extremely high. In the face of challenges, the staff of the Northwest Academy's Huangcheng Pumping and Storage Department took root in the first line of the site and linked with the construction in real time: through real-time geological sketch and advance forecast, dynamically optimized the design support parameters, participated in the joint acceptance of key processes in the whole process, provided timely technical guidance, and effectively ensured the construction safety; The EPC General Contracting Management Department of Huangcheng Pumped Storage Power Station coordinated all parties, organized the demonstration and strictly. All the builders unified their thinking and faced the difficulties. In the continuous struggle for 420 days and nights, they strictly controlled the safety, quality and progress management, and finally realized the high-quality and safe connection of the two channels.
