On August 31, the starting ceremony of the Guangdong Water Resources Configuration Project of the North Bay Bay was held simultaneously in Beijing, Guangzhou, and Maoming, marking the official construction of the project.

The reporter learned from the scene that as one of the "horizontal" of the "five vertical and five horizontal" water resources in Guangdong Province, the project covers Yunfu, Maoming, Yangjiang, Zhanjiang, 13 counties and 112 towns and villages. Solve the problem of water resources on western Guangdong, especially the Leizhou Peninsula.

"Water Difficulty problem" needs to be solved urgently

From 2019 to 2021, Xuwen County, Zhanjiang City continued to appear high temperature day in April to June, and the small second reservoir and lake water level next to Xiaqiao Town fell to the state of dead water. The minimum rainfall since the meteorological data, so many rockets were launched to "borrow" the rain to the sky; in February 2021, the farmland such as Shuikou and Zhenlong in Xinyi City cracked due to drought. ; In May 2021, the drought drought in Luoding City reached heavy drought, local special drought ...

The reporter learned from the Guangdong Provincial Department of Water Resources that the western Guangdong, especially the Leizhou Peninsula, was affected by droughts all year round. The problem of uneven time and space distribution is serious. According to incomplete statistics from the water conservancy department, since 1949, the Leizhou Peninsula has experienced drought in 56 years, of which severe droughts have occurred. drought.

At the same time, affected by the problems such as superpower water mining, agricultural and ecological water, and the lack of emergency spare water sources, the problem of insufficient water resources carrying capacity in western Guangdong was further highlighted. However, there are sufficient arable land resources in Leizhou Peninsula and good light and heat conditions, but it is the main commodity grain base and the main production area of ​​high -efficiency economic crops in Guangdong Province. In the planting place, the amount of agricultural water use has increased sharply.

"There are more than 140 households and more than 800 people in our village. From liberation to now, they are drinking underwater. Some wells have been shot more than 300 meters to have water when they are drought. Crops are also irrigated by well." Huang Kanxue, a villager in the Beishan Village of the Commission. Guo Chaodong, Secretary of the Northern Injo Village Committee of Xiaqiao Town, said that the 1475 acres of paddy fields and 1500 acres of forest land in the village mainly planted pineapple, rice, sugar cane, corn, etc., and also could not guarantee production due to lack of water.

Ringbei Bay Guangdong Water Resources Configuration Engineering Route Map

Today, Zhanjiang, Maoming, and Yangjiang City are important cities of the Beibu Gulf urban agglomeration, and an important part of the new coastal economic belt in the new landscape of the "One Core One Belt and One District" region. The problem of water resources is restricting the economic development of the four cities in western Guangdong. As a major cross -watershed water transfer water project with the largest water flow flow, the longest water traffic line, the most widely received water area, the most widely water area, and the most investment in Guangdong Province, the construction of Guangdong Water Resources Configuration Project on Beibu Gulf has become the key to breaking the situation.

Water West River "Request Relations" Western Guangdong

From the mission letter of the overall plan of the water resources allocation project in the North Bay Water Resources in 2017, the Ministry of Water Resources was approved by the Ministry of Water Resources and issued the overall plan of the water resource allocation project of the Beibu Gulf in 2020, and then to 2022, the Guangdong Water Resources Configuration Project of Beibu Gulf The feasibility study report was approved by the National Development and Reform Commission, with a total investment of 60.643 billion yuan, a total length of 500 kilometers, and a total length of 96 months of the Guangdong Water Resources Configuration Project. Yunfu Four City.

The reporter learned from the scene that the project consists of Xijiang Water source engineering, water recasting trunk project and split line project. It will take the water from Xijiang, Yunfu City. Open the mountains, connect 11 reservoirs, including Xijiang and Gaozhou Reservoir, Heidi Reservoir, to form a water supply pattern of "one river, two warehouses and three points", and build a large -scale complex water network system covering the 13 districts and counties of 4 cities and counties in western Guangdong. Water source interconnection and mutual preparation.

Among them, Xijiang Water source engineering pumping stations were designed to take 110 cubic meters per second, and the design ranging was 162.0 meters; the water transport trunk line was 201.9 kilometers long. 298.0 kilometers, among which the Yunfu dividing trunk line is 25.8 kilometers long, and the first design flow is 10 cubic meters per second; Maoyang's stem line is 95.2 kilometers long, and the first design traffic is 26 cubic meters per second. Every second.

According to Yi Yuetao, deputy director of the Pearl River Water Resources Commission of the Ministry of Water Resources, after the completion of the Guangdong Water Resources Configuration Project of Beibu Gulf, the average annual increase in water supply by the water exit water outlet has reached 2.079 billion cubic meters, of which 1.438 billion cubic cubic cubic cubic cubic cubic cubic cubic cubic cubic cubic cubic meters Rice and agricultural irrigation water supply is 641 million cubic meters, which can greatly improve the water supply guarantee capacity of western Guangdong, especially the Leizhou Peninsula, and provides important strategic support for the high -quality development of the local economy.

"The project will add 1.85 million acres of irrigation area, which can be returned to the amount of irrigation water crowded by the living industry to ensure that the grain fields in the core areas of the country such as Lianjiang and other countries can be produced. The crowded ecological environment was 185 million cubic meters of water, which greatly improved the regional water ecological environment. "Shen Hongxing, deputy director of the Guangdong Provincial Department of Water Resources. According to preliminary estimates, the construction of the project can also drive GDP to increase by 0.09 percentage points, adding 300,000 new jobs. Technology attack construction problem

"From Xijiang water to the Leizhou Peninsula, to the door of our house, there is no need to worry about drinking water and life in the future. I hope to completely solve the situation of lack of water and drought on the Leizhou Peninsula. Huang Kanxue, a villager in Beishan Village, Qiaonan Village Committee of Zhenqiao, said when he heard the construction of the Guangdong Water Resources Configuration Project of Beibei Bay. In an interview, Huang Kanxue said that it was expected that after the project was completed, he could solve the difficult situation of Xuwen County's "ten years and nine droughts" for a long time, and drink high -quality drinking water.

The project is extended from Yunfu's ground -hearted pumping station, and then extended through Maoming to Maoyu Reservoir and Dalongqiao Reservoir in Yangjiang City. A variety of bad geological segments such as high ground stress and rock explosion stratum. The single hole of the Yunkai Mountain Tunnel of the Water Creation Line is 64.48 kilometers long and the maximum burial depth reaches 910 meters. From engineering design to construction, to the operation and maintenance after completion, how can we talk about these problems caused by these hydrological geology?

"This time, a total of 12 rock tunnels were excavated in a full break (hereinafter referred to as 'TBM'), of which 6 of them were more than 9 meters in diameter, and the localization rate of the equipment was more than 70%." Wang Dujuan, deputy general manager of China Railway Equipment Wang Dujuan, Said. Wang Dujuan told reporters that, as the "King of Digging Paers" as construction machinery, TBM digging high efficiency and good excavation quality during tunnel construction. Under the conditions of hard rocks, the speed of excavation can reach 250 meters to 450 meters per month, so 3-5 times the explosion method.

"Some faults are more likely to pass by a little bit, and some faults are more difficult." Wang Dujuan pointed out that the biggest problem that the project may encounter in construction is the broken tape of the fault. Basically, every one is every one. The TBM tunnel has a crushing layer, and the size of the crushing layer will affect. Therefore, from the design level, a horizontal passage will be hit. After the construction staff enters, it will be processed by drilling. Risk, and optimize the existing TBM structure and reduce the phenomenon of card machines.

In the buried deep tunnel, TBM may also encounter hard rock explosion or large soft rock deformation. In the hard rock excavation process with stress concentration, rock explosion will be generated. People are even the condition of injury equipment; and the large soft rock deformation may "hold" this excavator, so there will be a problem that the card machine needs to be out of trouble. It is particularly large, but it is high.

Liu Yuanxun, chief engineer of the Guangdong Water Resources Configuration Engineering Project Design of the Beibu Gulf Bay, told reporters that the design of the project water pumping station design is 162 meters. After the water pump station is about 10 kilometers long and 8.1 meters in diameter, there will be pressure tunnels. The water pressure in the cave increases, and the HD value of the high -pressure tunnel (the product of the working water head and the inner diameter of the pipeline) reaches 1420, which is currently the highest long -distance large -diameter water adjustment project in China.

Liu Yuanxun introduced that, given that the HD value of the tunnel in this project is particularly high, and the research and design of tunnel lining structure is difficult, if pressure cannot be affected, it will cause major accidents. "In response to the key difficulties of design, construction, and operation and maintenance, we rely on scientific and technological innovation to focus on scientific research and research on major technical problems. We have compiled the" Outline of the Research Research Research Research Research Research on Water Resources Configuration Engineering in Beibu Gulf ", which will lay a solid foundation for the smooth construction of the project. . "Liu Yuanxun said.

Expert said | Evidence of engineering special expert Chen Xiangsheng's interpretation influence

From the East Deep Water Supplying Project in the 1960s, to today's Pearl River Delta Water Resources Configuration Project and the Guangdong Water Resources Configuration Project of the North Bay Bay, Guangdong is accelerating the implementation of eight major projects to build a backbone network, flood prevention safety network, Wanli Bibi, Wanli Bibi 5 networks, rural water conservancy guarantee networks, and smart water conservancy networks have promoted the province's level of modernization of water conservancy into the country's first echelon. As one of the five horizons of the Guangdong Water Resources Configuration of Guangdong Water Resources Configuration Project, what is the difference between other projects?

"The north Bay Bay is relatively in the stage of development, and the local economic and social and land development intensity is relatively low. The mountains of western Guangdong are mainly mountain tunnels, facing industry nature and even world -class difficulties and challenges." I said in an interview. Chen Xiangsheng said that the project involves a variety of water sources and various users, covering the target of water supply, flood prevention, irrigation, ecology, etc. The high -efficiency scheduling operation of the water conditioning system requires multi -disciplinary integration.

Chen Xiangsheng pointed out that the project must not only achieve joint scheduling of Jiangku Water Network under complex water conditions, conduct engineering geological survey and research at the multi -phase complex erosion belt in the cloud -opening plot, and study high water under complex hydrogeological conditions under complex hydrogeological conditions. The structure of the tunnel lining is also considered to consider the problems of long -distance deep buried tunnel multi -function TBM construction, large -flow large -power centrifugal pump research and development application, long -distance deep -buried pipeline smart operation and maintenance guarantee under complex geological conditions.

In the process of planning and design of the Guangdong Water Resources Configuration Project in the North Bay, it also avoided scientific planning to the water ecological environment of the water regulation and the water ecological environment along the water area. Chen Xiangsheng said that the project's water port is located in the upstream of Sixian 滘, and the project has a flow of water less than 2700 m3/s (Sixian 滘 滘 陈 2 2500 m3/s+other water households with water households). It will adversely affect the ecological water demand and salty flow of Sixian. According to reports, the water supply of this project accounts for between 0.68%and 14.27%of the water resources along the water areas along the line. Only the water volume caused by the degeneration of the water increases slightly; after the project is implemented, the water area can be returned to the ecological environment of some river channels and groundwater, which can further improve the water environment in the water area.

Data Story | Guangdong Water Conservancy Construction "Tiger Power" is fully opened

According to data from the Ministry of Water Conservancy, as of the end of July, this year, 31,800 water conservancy projects under construction this year have reached 31,800, with an investment scale of 1.7 trillion yuan. People, including 1.233 million migrant workers. As an important area of ​​infrastructure investment, the construction of water conservancy infrastructure has achieved remarkable results, and it has become an important part of benefiting people's livelihood, stabilizing the economy, promoting growth, and protecting employment.

The reporter learned from the Guangdong Provincial Department of Water Resources that 2021 is the year of the "14th Five -Year Plan". Guangdong completed 72.5 billion yuan in water conservancy investment throughout the year, ranking first in the country. In order to promote Guangdong's leap from the province of water conservancy to a strong water conservancy province, Guangdong Province implemented the "851" water conservancy high -quality development blueprint with a total investment of more than 800 billion yuan. At above the yuan, it is planned to complete the investment of more than 80 billion yuan this year.

In July of this year, the Guangdong Provincial Water Conservancy Department exposed the "transcript" in the first half of the year. In the first half of the year, the province implemented a water conservancy investment of 66.36 billion yuan, accounting for 77.6%of the annual investment plan, and the annual investment of water conservancy was 45.69 billion yuan. At 57.1%of the investment target, the province's major water conservancy projects have started 2695 and the operating rate is 67.3%.

According to the data of the Guangdong Provincial Development and Reform Commission's "Guangdong Province 2022 Key Construction Project Plan", the total investment of key projects in the province in 2022 was 7.67 trillion yuan, and the annual planned investment was 900 billion yuan. Among them, in terms of water conservancy disaster prevention and mitigation, the two projects will be put into production this year, and there are 7 continuous construction projects. In terms of water resources protection construction, the introduction of Han Jiro's water supply project has been opened in July. Seven new start -up projects; in terms of agricultural water conservancy construction, there are three continuous construction projects and 1 new construction project.

Look at Maoming | Runze's party is empowering to develop thirst for enterprises

Text/Yangcheng Evening News all -media reporter Quanliangbo correspondent Zhuo Jian Si Chen Feihu

The Guangdong Water Resources Configuration Project (hereinafter referred to as the "Huanbei Project") is one of the 55 major water conservancy projects determined by the State Council. On August 31, the Huanbei Project held a opening ceremony in Xinyi City, Maoming. After completion, it will Runze Four Cities in the western Guangdong to meet most enterprises' water needs and help Guangdong to build a coastal economic belt. It is reported that in the process of promoting the implementation of the project, Maoming achieved city -level overall design and county -level leading promotion. In the future, the construction party integrates the experience of the Hejiang test section project into the project and complete the construction tasks at high quality.

Use embroidery ingenuity to blew the node number

Watching his own Guotian was flat, Liu Mingfang, a villager in Zhonghe Village, Guizi Town, Xinyi City, looked forward to the project as soon as possible. "Building a water conservancy project is a good thing to benefit future generations. The villagers expect to be completed as soon as possible." Liu Mingfang said that after the town government issued a document, party members and cadres walked home to explain the meaning of the project. Everyone knew the meaning behind it and supported the project with action.

In Guizi Town, more and more villagers like Liu Mingfang appeared in Guizi Town, and more and more villagers like Liu Mingfang appeared. They are eager to mature the green fruit of the north project as soon as possible to benefit western Guangdong. Nowadays, with the construction of the north project, a excavator starts at the scene, and a hot construction scroll is slowly unfolding.

It is reported that the total length of the line line of the Maoming section of the Huanbei Project is about 204km, and the total length of the Xinyi section line is about 45km, accounting for 22%of the total length of the Maoming section. It is the necessary line of Maoming and downstream areas to be the control line segment of the entire project. In the early stage, Xinyi completed the land collection land, forest land approval, and relocation and reform of national defense optical cable facilities.

Looking forward to the city of Xinyi, "Jinjiang Bai Li", "Landscape Double", "Concentrated Water Supply Project" ... A people's livelihood project has been implemented, which has enhanced government prestige. This time, the Xinyi section of the Huanbei Project involved 4 towns and 9 villages, and the total land acquisition area was about 1093.02 acres. In the previous example, ordinary people understand the significance of the project and cooperate with the land.

Xinyi patiently do a good job in the minds of the masses, and form a strong joint force to jointly promote construction. At present, Xinyi has strengthened the linkage of departments to clarify the list of key tasks, specific work requirements, completion time nodes, responsible units and responsible persons, and compact the responsibilities of all parties to ensure that the construction of the Xinyi section is completed.

Try to promote project acceleration first

On the north side of Gejiang Town, Maominghua Prefecture, Huanbei Engineering Hejiang Zhidong project has been completed. At present, the construction unit Guangdong Yuehai Holdings Group has shifted to Xinyi Pioneer, and there are still a lot of construction experience. "The construction of the test section project has important guiding significance for the entire project construction risk prevention, optimization design, construction period, and investment control." Jiang Jun, chief engineer of Guangdong Yuehai Yue Water Supply Co., Ltd. "Try it first", accumulate a lot of experience, and have confidence to complete the construction task of the Maoming section of the North Engineering of the North Engineering.

Liu Guangrong, the head of the first construction project of the four bays of China Railway, said that the construction party is fully settled in the project, and the project is expected to be about 2 years. After more than two months of investigation, the construction party will use the most advanced technologies to overcome difficulties such as dissolving water and soft soil, and complete the task as scheduled.

From the process of combing Maoming's first section to start construction, it is not difficult to find that Maoming has always insisted on planning and leading projects. Back to the project of the North Engineering project, Maoming earlier proposed the project's demand for water to take water and conducive to overall scheduling in the province; because more than 90%of the pioneering section of the Northern North Project is a tunnel project, Maoming City deliberately selected Hejiang Zhidong with complicated geological conditions as a test as a test as a test. Section project; complete project approval and all preliminary work in just one month ...

Purchase and movement, accumulated thick and thin hair. With a handful of chess, Maoming won the initiative, allowing the project construction to reflect the speed of Maoming, and was affirmed by the relevant departments of the provincial directly.

Add a new insurance for industrial development

After the completion of the project, it can optimize the regional water resources allocation pattern, further ensure the safety of production and live water safety, maintain the ecological environment of the river and lake, and systematically solve the problem of water resources in western Guangdong. The Gaozhou Reservoir will become the core of the western western water resource allocation reservoir, transforming from Maoming's "Life Reservoir" to a "western western water tower".

In addition to satisfying living water, it is mainly to "quench thirst" for enterprises. Green Chemical and Hydrogen Energy Industrial Park, Hydrogen Energy Industrial Park, Yangmei Industrial Park, and Airport Economic Zone in the Binhai New District of Guangdong are located in the arid areas.
