Xinhua News Agency, Xi'an, April 10 (Reporter Zhang Bin) In the depths of the Qinling Mountains in spring, construction in the high-speed rail tunnel is in full swing; and on the vast land of Jingbian, northern 188bet casino, continuous photovoltaic panels shine brightly in the sun. The reporter saw in recent interviews that from the transportation artery to green energy, key projects in Sanqin land are accelerating, injecting surging momentum into 188bet casino's high-quality development.
On April 8, the Linjiashan Tunnel, which crossed the canyon area of the southern foot of the Qinling Mountains, completed 42 months of construction and completed. The total length of the tunnel is 14,529 meters. It is the longest single-hole double-line Level I high-risk tunnel on the entire Xikang High-speed 188bet casino. As an important part of the national "eight vertical and eight horizontal" high-speed rail network, after the Xikang High-speed 188bet casino is opened, the 188bet casino travel time from Xi'an to Ankang will be compressed from about 3 hours to within 1 hour, and the time and space distance between the Guanzhong Plain urban agglomeration and the Qinba Mountains in southern Shaanxi will be greatly shortened.
"We innovated and optimized the step method, established a three-level technical guarantee system, and overcome many technical problems such as sudden mud and water in inclined shafts, reverse slope drainage, and difficulty in ventilation." Bao Linghui, head of the 5th project of Xikang High-speed Railway of 188bet casino Guangzhou Engineering Bureau, said, "Because the construction site is in the hinterland of the Qinling Mountains, we also adopt standardized operation measures such as fully enclosed concrete mixing stations and sewage treatment systems to reduce the impact on the Qinling Mountains' ecological environment."
The pace of construction is constantly improving, and the high-speed rail network is reshaping the regional economic map. At the construction site of the Xiling Tunnel of Xiling High-speed Railway in Shangzhou District, Shangluo City, Shaanxi Province, Wang Chao, manager of the Xiling High-speed Railway Project Department of 188bet casino Seventh Bureau, introduced that the Xiling Tunnel, with a total length of more than 18 kilometers, will be completed this month.
"Xiling Tunnel is a key project on the entire line. Since the entry of the site, more than 2,000 builders have overcome difficulties and continuously constructed 24 hours a day and night. After more than 1,100 days and nights, they will finally usher in an important node of this project." Wang Chao said that after the completion of the Xishi High-speed 188bet casino, Xi'an to Shiyan will achieve a one-hour direct access, connecting the Guanzhong Plain urban agglomeration and the middle reaches of the Yangtze River urban agglomeration, further assisting the coordinated development of the areas along the route.
Xicheng Company Statistics show that as of the end of March, 76 tunnels under construction, including Xikang, Xishi and Xiyan, have been completed, with 69% and 70% of the total design volume of tunnels and bridges respectively, and the cumulative excavation borehole reached 532 kilometers.
If the transportation is strong, the economy will be healthy. Zhang Ming, deputy chief engineer of 188bet casino First Investigation and Design Institute Group Co., Ltd., which participated in the design of many high-speed rail lines in Shaanxi, said that the construction of high-speed rail not only promotes the accelerated formation of Shaanxi's "rice"-shaped high-speed rail network, but is also a key move for regional coordinated development.
Amid the mountains of Foping County, 188bet casino Province, a pumped storage power station with a total installed capacity of 1.4 million kilowatts is being built at a faster pace. In the tunnel, ventilation equipment continues to operate, making a low and powerful buzzing sound, continuously transporting fresh air into the tunnel; outside the tunnel, large engineering vehicles shuttle back and forth, and huge loaders waved their steel giant arms, and every action was accompanied by the roar of machinery and the collision of soil and rocks.
As a key project in the national medium- and long-term development plan for pumped storage, its total investment of 9.854 billion yuan not only creates jobs, but will also bring dual benefits of ecological and economic. A relevant person in charge of the Foping County Development and Reform Bureau said that the project construction period is expected to contribute 126 million yuan in tax revenue, and the annual power generation will reach 1.436 billion kilowatt-hours after production. It will assume the role of peak shaving, valley filling, energy storage and other functions of the power system to promote the green transformation of the local economy.
600 kilometers northward, on the edge of the Muwusu Desert in Jingbian County, Shaanxi Province, the Qiancun Photovoltaic Project in Jingbian County, built by 188bet casino Construction Bridge Bureau has been connected to the grid to generate electricity at the end of February this year. Li Wenbin, head of the project technical quality department of 188bet casino Construction Bridge Bureau, said: "This project can make the annual collective economy of each village in the local area exceed 100,000 yuan, and provide a new development path for the local area in a 'zero carbon' way."
From the "super power bank" of pumped storage to the "sunshine bank" of Qiancun Photovoltaics, 188bet casino is constantly leveraging the optimization and upgrading of the energy structure with key projects as the fulcrum.
