The relevant person in charge of the Ministry of Water Conservancy said that this marks the entry stage of cross -basin water adjustment projects with the largest water diversion flow in Guangdong in history, the longest water transmission line, the most complicated construction conditions, and the highest total investment.

The project is located in the southwestern part of Guangdong Province. It consists of water source engineering, water transmission trunk engineering, and water pouring trunk project. The total length of the water flow line is about 499.9 kilometers. The project takes water from the river section of Xianxinxin Village, Xijiang, Yunfu City, pumping through the pumping station, through the Yundai Mountain, and adjusting the water to the Leizhou Peninsula. The water supply range includes Yunfu, Maoming, Yangjiang, and Zhanjiang. Wan, will play the role of water supply lifeline.

System hydration to improve water safety guarantee capabilities

From June 18th to 19th of this year, Li Guoying, the party secretary and minister of the Ministry of Water Resources, emphasized that it is necessary to coordinate development and security, scientifically planning and design, and comprehensively accelerating the construction of major water conservancy projects, and make water conservancy contributions to stabilizing the economic market. Provide strong support for comprehensively improving water safety security capabilities.

In western Guangdong, especially the Leizhou Peninsula, it has been known for its drought since ancient times. It has weak natural storage capacity, great changes, and long -term problems in water resources have troubled the western people in western Guangdong. As early as 2007, the Ministry of Water Conservancy organized a comprehensive plan for the Pearl River Basin in 2007, and required a balanced allocation of water resources based on the overall basin and water resources to solve the problem of water shortage in western Guangdong. Guangdong Province has successively launched the implementation of the "Drought Treatment Plan for the Southwest of the Leizhou Peninsula" and "Thirteenth Five -Year Plan" of the Leizhou Peninsula Water Construction, which focuses on optimizing the Water Resources allocation pattern of Leizhou Peninsula, accelerating the construction of farmland water conservancy, improving water conservancy and disaster prevention and mitigation capabilities. Promote the four aspects of the construction of water ecological civilization for systematic governance.

According to the relevant deployment, the Pearl River Water Resources Commission of the Ministry of Water Conservancy planned the environment from the north project from Xijiang dry flow to western Guangdong and other regions in the comprehensive planning of the Pearl River Basin. In 2013, the Pearl River Basin Comprehensive Plan was approved by the State Council, laying a planning foundation for the project of the North China Project.

"After the completion of the north project, it can solve the problem of water resource carrying capacity in western Guangdong in the long run, and the problem of failure to match the economic development layout, which greatly improves the regional water supply safety guarantee capabilities." Qiao Jianhua, deputy director of the Ministry of Water Resources Planning and Planning, introduced that the project was determined by the State Council to determine One of the 55 major water conservancy projects that have been accelerated this year, and it is also an important part of the National Water Network.

According to reports, the Huanbei Project mainly supply water for urban and rural life and industrial production, taking into account agricultural irrigation, and at the same time, it creates conditions for improving the ecological environment of the water. "After the project was completed, the water supply was increased by 2.079 billion cubic meters of water, of which 1.438 billion cubic meters of urban and rural life and industrial water supply were 1.438 billion cubic meters, and agricultural irrigation water supply was 641 million cubic meters." Yi Yuetao, deputy director of the Pearl River Water Resources Committee of the Ministry of Water Resources.

"After the project is completed, it can be reduced by 566 million cubic meters of groundwater, and the crowded ecological environment water is 185 million cubic meters, which plays an active role in improving the ecological environment." Said Shen Hongxing, deputy director of the Guangdong Provincial Department of Water Resources.

Scientific and technological innovation, facing the difficult point of the construction of the project

As the largest national water conservancy project in Guangdong, which is the largest in China, and the industry's attention, it is facing many key difficulties at all stages of the North Engineering design, construction, and operation and maintenance, and there are many industry and even world -class technical problems.

"For example, under the condition of complex water conditions, the construction and joint dispatch of Jiangku Water Network, the research and design of the lining structure of high water pressure tunnels under complex hydrogeological conditions, and through complicated geological conditions under the condition of long -distance deep buried tunnel multifunctional TBM development and construction. Long Smart operation and maintenance and guarantee from deep burial pipelines ... "Liu Yuanxun, chief engineer of the project design of the North Engineering Project, for example. These are all subjects that need to be studied and solved in engineering planning and construction.

Through Xijiang Water Pump Station, Waterwater Line, etc., the large and medium -sized reservoirs such as Xijiang, Gaozhou, Heidi, and other large and medium -sized reservoirs have established a large -scale complex water network system covering the 13 districts and counties of 4 cities in western Guangdong. In the huge water network system, there are time and space differences in rainfall and runoff in the water area and water area. In the face of complex water conditions, how to improve the water supply guarantee of water areas, how to deploy water and storage reservoirs to achieve water resources time and space The balanced goal needs to start a large -scale, cross -ride networking joint scheduling research to achieve efficient optimization of water resources.

The water flow line of the north project is about 499.9 kilometers long, and the largest hole diameter of the tunnel is 8.2 meters. The cloud -open plot and the coastal plain with complex geological and hydropological conditions along the line are prominent. The product with the inner diameter of the pipeline reached 1420, which is the highest long -distance large -diameter water transfer project in China. There are very few cases of similar projects at home and abroad. How to control the development of tunnels during the operation period is developed by internal fracture and prevent internal water seepage. Related research.

"In response to the key difficulties of design, construction, and operation and maintenance, we rely on scientific and technological innovation, focus on scientific research on major technical problems, fully demonstrate, and compile the" Outline of the Scientific Research Research Research on Water Resources Configuration Engineering in Beibu Gulf "," Liu Yuanxun said, " With the comprehensive development of scientific research topics, it will lay a solid foundation for the smooth construction of the north project. "

Speed ​​up construction to help stabilize and benefit people's livelihood

In May of this year, the State Council issued the "A Policies and Measures for the Economy", and launched 33 measures in six aspects, and issued a notice to promote the promotion of a package of policies and measures as soon as possible to ensure the timely implementation of the implementation, as soon as possible to stabilize the economy and help the economy and help Enterprise relief has a greater policy effect. "Accelerating a group of mature water conservancy projects" is one of the 33 measures. "Based on preliminary estimates, the construction of the north project can drive GDP to increase by 0.1 percentage points." Yi Yuetao introduced. In addition to the north project, a large number of major water conservancy projects in Guangdong are accelerating the pace of construction. At present, Guangdong has entered the largest historical period of water conservancy investment construction, and water conservancy construction has become an important measure for steady growth and benefiting people's livelihood.

"During the" Fourteenth Five -Year Plan "period, the Guangdong Water Conservancy Investment Plan plans to complete 405 billion yuan, which is 2.2 times that of the" Thirteenth Five -Year Plan "period. In the first half of this year, the province's water conservancy investment completed 45.69 billion yuan, a record high." Shen Hongxing introduced.

Some experts have pointed out that the investment in major water conservancy projects is huge, and it has a large role in promoting economic development. Through the multiplication effect, new consumption and investment may be derived in the future, which is expected to drive economic growth.

"In the next step, we will accelerate the construction and work of the Guangdong Water Resources Configuration Project in the North Bay Bay, strive to play the efficiency of engineering as soon as possible, effectively improve the water security guarantee capabilities in western Guangdong, and contribute to stabilizing the economic market." Shen Hongxing said.
