"During the Mid -Autumn Festival holiday, the construction workers adhered to the front line and hurriedly construction. The traffic hole in the field went smoothly and crossed the core area of ​​the Cuoli broken belt of the project area." On September 13, the construction of the construction of the water pumping power station in Hami entered the mountainous area into the mountainous area deep At the same time, the busy State Grid Xinyuan Xinjiang Hami Water Pumping Establishment Co., Ltd., which is busy at the construction site, said the law and government.

Hami Water Package Power Station is located in Sandaogou Village, Tianshan Township, Yizhou District, Hami. It is a key project of the autonomous region. The power station has a dynamic investment of 8.23 ​​billion yuan. Construction started in 2019. The design and installation of 4 300,000 kilowatts of generator sets are designed and installed. The total installed capacity is 1.2 million kilowatts, and the annual power generation is 1.368 billion kilowatt -hours. 596,000 tons of carbon dioxide. According to the plan, the first unit was put into production in the first unit in 2024. During the "Fourteenth Five -Year Plan" period, all 4 machine groups were put into production and power generation. It mainly undertakes the tasks of peak adjustment, frequency adjustment, energy storage, system spares and other tasks of Xinjiang and Northwest Power Grid to ensure the security of the power grid. Stable operation.

The power station is mainly composed of the lower reservoir, the upper reservoir, the water recotion system, the factory building of the underground generator set and the ground switch station. The channel. The Tianshan Curlers broken belt located in the area where the traffic cave is located, causing a 150 -meter -long surrounding stone state to become unstable, becoming a difficulty in construction.

"Crossing Ku Lai's broken belt is a very challenging construction task in the entire project. After calculation, 9 holes in all engineering projects are affected by the broken belt." Manager Zhao Yongzhi said that in order to ensure the quality and safety of the project, two innovative technologies were applied in construction. The first is to use TCT prediction technology when excavating in the cave. Just like performing a CT examination for the human body, you can analyze the rock body and establish a three -dimensional model to display the geology in front of the rock body in front of the cave, ensure construction construction, ensure construction construction Second, the construction of the tube sheds is used to ensure the safety of project construction.

"At present, the traffic hole project has successfully passed the core area of ​​the Cuilei broken belt. The overall construction speed has increased, and the daily ruler reaches 5 meters to 6 meters." Underground engineering construction has accumulated technology and experience.

Zhao Yongzhi said that since the beginning of this year, the company's annual construction plan has been promoted smoothly at the beginning of the year. The relevant departments of Hami City and Yizhou District have strongly supported the construction of the project during the prevention and control of the epidemic, and actively coordinated the necessary production and living materials to enter the market. Effective guarantee. In the next step, the company will seize the construction period, grasp the construction of traffic holes in accordance with the schedule, excavate the upper and lower storage connecting the road tunnel, penetrate the flood discharge sand cave and the diversion hole, and lay the foundation for the construction of the main project.
