On August 11, with the slowly launch of the knife tray, the first major domestic inclination (39 degrees upward) TBM "Yongning" (39 degrees up), jointly developed by the State Grid Site, China Railway Equipment, and China Railway Equipment. , Successful acceptance in Zhengzhou. The equipment will be applied to Henan Province's largest installed capacity pumping storage power station -State Grid Xinyuan Henan Luonan Luoning Pumping Power Power Drimp to Dreatment Landwing Project, filling the technical gaps in the field of large -scale incumbent slope construction construction. The transformation and upgrading of the energy storage power station engineering construction model injected new impetus.

Luoning Power Power Power Station is located in Luoning County, Luoyang City, Henan Province. It is a major energy project of the "Thirteenth Five -Year Plan" of the country. The total installed capacity of the power station is 1.4 million kilowatts. The first -class diagonal well plan has created a new model of a well -pumping storage power station in China.

"Construction of water storage power stations must build water drain wells, and the water drain well is tilted. The existing construction method adopts the drilling method and the construction is made from top to bottom, and the Yongning TBM can be used. In the bottom, the construction of the shield method is more secure and environmentally friendly, which greatly improves the level of craftsmanship and excavation progress. It has created a new model of pumping storage power stations. "In an interview with Elephant Journalists, the key to China Railway Equipment Group Technology Center President of the Component Branch Ning Xiang Ke said.

In the total installed workshop of the China Railway Equipment Group, as the first domestic inclination (39 degrees upward) diagonal well TBM, the solemn "Yongning" is waiting for acceptance. On the knife plate of Yongning, the dark green decoration shows the appearance of "double dragon hugs", which is lively and vivid, rich in meaning, symbolizing the pursuit of a better life.

(The knife -oriented decoration shows "Shuanglong Holding Pearl")

The "Yongning" oblique well TBM, the excavation diameter of 7.23 meters, the No. 1 Drimpy Water of the Construction 927 meters, No. 2 Drimp to 873 meters, the inclination angle is 36.236 degrees and 38.742 degrees, respectively. It is 184 to 684 meters, mainly for stroke fresh spotted granite, and crosses 2 broken layers to break.

As the leader of the mechanized construction revolution of pumping storage tunnels, China Railway Equipment has tailored to the project to develop a large inclination diagonal well TBM "Yongning", and for large inclination equipment, scum blocking, material transportation, and fluid hydraulic containers Technical problems such as adaptive adaptation have improved the innovative improvement of 32 systems, which greatly improves the overall reliability and durability of the equipment. Its applications will greatly improve the essence of engineering and safety, and improve the quality, process level and excavation progress. Significantly improve the construction environment.

It is reported that after the completion of Luo Ning's pumping power storage power stations, it mainly undertakes the tasks of peak adjustment, valley reclamation, frequency adjustment, phase adjustment, and emergency reserve of Henan Power Grid. The realization of carbon neutrality, as well as enhancing Henan Power Grid peak adjustment capabilities, optimizing power structure, improving the security of power grid, and promoting local economic and social development.
