On the 7th, the Jiangzuhan project was officially started.

Take the water from the Three Gorges Reservoir in the Three Gorges Reservoir, penetrate 194.8 kilometers through the mountain, and arrive at the Hanjiang Anlekou River estuary at the lower reaches of the Danjiangkou Reservoir. Essence

The start of the construction of the Jiangzuhan and Han Dynasty marked the start of the construction of the subsequent project of the South -to -North Water Diversion.

The construction of the Jiangsu and Hanfu project: The construction of the follow -up project of the South Water and the North Diversion started

At 10:28 am on the 7th, the Anlekou River estuary of the Hanjiang River on the right side of the Danjiangkou Reservoir was about 5 kilometers. Large machines such as excavators and slag cars on the construction site began to shuttle.

The introduction of the river -replenishment project, which is responsible for the construction and operation of the South -to -North Water Diversion Group of China, is the first construction project of the follow -up project of the South -to -North Water Diversion.

"Guizhou and supplementing Han project is the subsequent water source of the South -to -North Water Diversion Middle Line Project. The water from the Three Gorges Reservoir of the Yangtze River into the Hanjiang River, the total length of the water water line is 194.8 kilometers, of which 194.3 kilometers long in the water tunnel. Chairman Jiang Xuguang said that after the project is completed, it will increase the amount of water transfer in the north -north -north -north water transfer project.

The Yinjiang Buhan Project consists of comprehensive rectification projects of the total water plowing project and the influence of the river section of the Hanjiang River. Because the water outlet of the Jiangjiahan project is under the Danjiangkou Reservoir Dam, the water in the Three Gorges Reservoir area is not directly north -transfer. Instead, it improves the water resources deployment capacity in the Hanjiang River Basin to increase the water volume of the north. The Han River's influencing comprehensive rectification project of the river section is mainly to rectify the river section of about 5 kilometers under the Danjiangkou Reservoir dam.

Regarding the Jiangjiahan project, Niu Xinqiang, an academician of the Chinese Academy of Engineering and the chairman of the Changjiang Design Group Co., Ltd., listed 6 "most": my country with the longest length of the water tunnel in my country; Dimension water tunnel, an equivalent hole diameter of 10.2 meters; the longest long distance of my country under construction is a pressure -induced water tunnel tunnel, with a maximum diversion of 212 cubic meters per second. The tunnel; the largest tunnel tunnel in my country with the largest amount of excavation projects in China; the long -distance removal water tunnel tunnel with the largest comprehensive difficulty under construction in my country, the maximum buried depth of 1182 meters.

"The geological conditions along the total trunk line of the project are complex and the construction is difficult. It is one of the challenging projects in my country's water transfer project. The project will promote the improvement of my country's major infrastructure technology innovation capabilities." Niu Xinqiang said.

"The engineering area is located in the mountainous area, the gully is vertical, the mountains are high and the mountains are dense. The field survey of the project has overcome many unimaginable difficulties. Finally, the best line channel is found to maximize the strong rock dissolved area and scale that can easily lead to tunnel disasters that can easily lead to tunnel disaster. A huge break zone. "Said Jia Jianhong, a senior engineer of the Yangtze River Design Group.

Gao Bihua, chairman of Jianghan Water Network Construction and Development Co., Ltd., the legal person of the Jiangsu and North Water Diversion Group of Yinjiang Buhan Engineering Project, said that in order to cope with these engineering technical problems, Jianghan Water Network Company of the South Water and North Diversion Group carried out a wide range of engineering research, actively organized scientific research research, strengthened technical and equipment research To strengthen the research of advanced geological forecasting, provide guarantee for hidden risks in advance, carry out research on grouting materials and process, resolve the risks brought about by the deep and high water pressure, and promote the construction of safety.

Li Yong, director of the South -to -North Water Diversion Engineering Department of the Ministry of Water Resources, said that the Ministry of Water Conservancy will urge and guide the project legal person to establish and improve the quality management system, ensure the quality of engineering construction, implement the standardization management of the construction process, and effectively build the project of the Jiangu and Hanuanghan projects to be safe, assured, high -quality, high -quality project.

"Da Water Basin" joined forces to "Da Water Tank": the two "heavy weapons of the country" of the Three Gorges Project and the South Water Diversion Project

Why did the Jiangjiahan project start construction at this time? Niu Xinqiang told reporters that since the water flow of the South Water and North Diversion Middle Line, it has achieved significant economic, social and ecological benefits. With the promotion of the coordinated development of Beijing -Tianjin -Hebei, the construction of the Xiong'an New District, the development of the Central Plains urban agglomeration, and the continued in -depth development of the overall governance of the groundwater in North China, the water supply structure of the water area is not reasonable, the regional water resources coordinate and distribution capacity are relatively relative. Insufficient contradictions will be further prominent.

At the same time, due to the changes in the upstream water situation and the increase in the growth of water demand for the Hanjiang River Basin, the ability to stabilize water supply in the first phase of the South Water and North Diversion Middle Line needs to be increased. As the subsequent water source of the South -to -North Water Diversion Middle Line Project, the introduction of the river and the northwater transfer project will closely connect the Three Gorges Project with the two major "countries of the country" with the two major "countries of the country".

The Three Gorges Reservoir of the Yangtze River is my country's strategic water source, and it is also the "large water tank" of the Yangtze River Basin. It has an average of more than 400 billion cubic meters of water in the reservoir for many years. , The amount of water is abundant and stable.

The Danjiangkou Reservoir is the controlling backbone project of the Hanjiang River Basin. It is an important water source of the water transfer project in my country. It is also the "large water basin" of the Hanjiang River Basin. Mi, a normal water storage level below 170 meters below 16.12 billion cubic meters, is the only water source of the first phase of the South -to -North Water Diversion Middle Line. "After the implementation of the Jiangsu and Han Dynasty project, the water volume of the northern part of the mid -line can be increased by an average of 9.5 billion cubic meters planned by the first phase of the project to 11.51 billion cubic meters. With the North China region, accelerate the construction of the main skeleton and artery of the national water network, and further optimize my country's water resources allocation pattern. "Li Yong said.

At the same time, the project of Yinjiang and the Han Dynasty will also create conditions for the large -term water adjustment scale for the introduction of Hanji Wei. The average annual diversion of the Hanji -Weiwei project in the Hanjiang River can increase from the recent 1 billion cubic meters to 1.5 billion cubic meters to effectively ensure water supply safety in the Guanzhong Plain.

In addition, after the implementation of the Jiangu and Hanfu project, it can replenish 610 million cubic meters of water from the middle and lower reaches of the Han River each year. The project water along the line is 300 million cubic meters, which greatly improves the ability of the Hanjiang River Basin and regional water resources.

Ecological priority, human water harmony: creating a "business card" for green water regulation projects

How to reduce the impact on the environment during the construction of the Jiangu and Hanfu project? Jiang Xuguang said that the South -to -North Water Diversion Group will actively take various measures to slow down or eliminate the adverse effects on the ecological environment, and strive to make this project a "business card" for green water -regulating projects.

During the planning and design stage, the total stem lines of the water recall have been clearly pierced by ecologically sensitive areas such as nature reserves and forest parks under the form of tunnels to minimize the impact on ecological sensitive areas as much as possible. At the same time, various environmental protection measures such as optimizing construction methods, habitat restoration, optimization scheduling, and water environmental governance.

At the stage of engineering construction, establish an ecological environmental management system, strictly implement environmental protection measures as the environmental protection system that designed, constructed, and use it at the same time, and follow -up monitoring of the effectiveness of various environmental protection measures to promote various items to promote various items Ecological environmental protection measures are implemented.

Niu Xinqiang believes that after the completion of the Jiangsu and Hanfu project, it will help further exert the benefits of the South -to -North Water Diversion Middle Line Project, increase the amount of water -oriented water, and improve the water supply guarantee capacity of the water area in the middle line. The contradiction between ecological environmental protection.

"After the completion of the Jiangjin and Han Dynasty project, it can replenish 610 million cubic meters of water from the Hanjiang River each year. It will improve the conditions of the Hanjiang water resources and alleviate the ecological environment pressure facing the middle and lower reaches of the Hanjiang River." Hu Jia, deputy director of the Water Conservancy Commission of the Water Conservancy Museum, said.

Zhang Xiangwei, director of the Division of the Ministry of Water Resources Planning and Planning, said that the introduction of the Jiangsu and Hanfu project is the first construction project of the follow -up project of the South -to -North Water Diversion. The next step of the South -to -North Water Diversion Project will continue to deepen the preliminary work of the East and Western Line projects and promote the construction of the project. Through the construction of the subsequent project planning of the South -to -North Water Diversion, further open the north -south water transmission channel, build the main skeleton and large arteries of the national water network, and comprehensively enhance the ability and level of the macro -allocation and scheduling of national water resources.

It is understood that in accordance with the decision -making arrangements of the Party Central Committee and the State Council, under the unified leadership of the high -quality development leadership group of the South -to -North Water Diversion Project, through in -depth research and demonstration of all parties, the overall idea of ​​the subsequent planning and construction of the South Water and North Diversion was further clarified. Relevant parties are steadily promoting the implementation of relevant work, accelerating the construction of the main skeleton and artery of the national water network, and providing solid water security guarantees for comprehensively building socialist modern countries.
