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 from Yangcheng Evening News 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. Fundamentally solved the problem of shortage of water resources on the western Guangdong region, especially the Leizhou Peninsula, Runze Guangdong has a population of millions.

"Water Travel Questions" need to break through urgently

From 2019 to 2021, Xuwen County, Zhanjiang City continued to appear high temperature day in April to June. ); In July 2020, the minimum rainfall since the meteorological data appeared in Yangjiang City, and even a number of rockets shot into the sky to "borrow" the rain; in February 2021, the farmland in Shuikou, Zhenlong and other towns in Xinyi City City Drought and cracked, villagers were worried about water shortage in the spring farming season; in May 2021, the meteorological drought in Luoding City reached heavy drought, local special drought ...

Western Guangdong -especially Leizhou Peninsula -suffered from drought all year round. 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 in 25 years. In 2015, Leizhou, Xuwen, Suixi and other places appeared extremely drought with the least rainfall since the meteorological records.

At the same time, affected by problems such as superpower water mining, agricultural and ecological water, and lack of emergency spare water sources, the problems of insufficient water resources carrying capacity in western Guangdong have been further prominent. Leizhou Peninsula has sufficient arable land and good light and heat conditions. It is the main commodity grain base and the main production area of ​​high -efficiency economy crops in Guangdong Province. The amount of agricultural water increased sharply.

"There are more than 140 households and more than 800 people in our village. From 1949 to the present, they have been drinking groundwater. When they are drought, some wells have more than 300 meters before they have water. Crops are also irrigated by well." Huang Kanxue, a villager in the Beishan Village of the Commissioner. Guo Chaodong, Secretary of the North Injo Village Committee of Xiaqiao Town, introduced that there are 1475 acres of paddy fields and 1500 acres of forest land in the village. It is mainly planted in pineapple, rice, sugar cane, corn, etc., and it cannot guarantee production due to lack of water.

Today, Zhanjiang, Maoming, and Yangjiang are important cities of the Beibu Gulf urban agglomeration, and an important part of the new coastal economic belt in the new pattern of the "one nuclear area and one area" area. The problem of water resources is restricting the economic development of the four cities in western Guangdong. As a major cross -riversal recruitment water project with the largest water traffic flow, the longest water traffic line, the longest water area, the most widely water area, and the most investment in Guangdong Province so far, the construction of the Guangdong Water Resources Configuration Project on Beibu Gulf has become the key to breaking the situation.

Xijiang will connect with 11 reservoirs. The picture shows Zhanjiang Heidi Reservoir

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 has been approved by the National Development and Reform Commission ... Today, the total investment of 60.643 billion yuan, 500 kilometers in length, and a total of 96 months of the Huanbei Bay Guangdong Water Resources Configuration Project will be officially started. , Maoming, Yangjiang, Yunfu, four cities.

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

Among them, the water flow of the Xijiang Water source engineering pumping station is 110 cubic meters per second, and the design of the design is 162 meters. 298 kilometers long, of which the Yunfu dividing trunk line is 25.8 kilometers long, and the first design traffic 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. It is 27 cubic meters per 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 on Beibu Gulf, the total amount of water supply by the water in the water in the water is 2.079 billion cubic meters per year, of which the urban and rural life and industrial water supply was 1.438 billion. Cubic meters and agricultural irrigation water supply of 641 billion cubic meters 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 change 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 this when he heard the construction of the Guangdong Water Resources Configuration Project of Beibei Bay. Huang Kanxue said that it is expected that after the project is completed, it can change the difficult situation of Xuwen County's "ten years and nine droughts" for a long time, and drink high -quality drinking water.

The project extends from Yunfu's ground -hearted pumping station, and then extended 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 largest burial depth reaches 910 meters. It is the longest and deepest water tunnel tunnel in Guangdong. From engineering design to construction, to the operation and maintenance after completion, how to overcome the problems brought by these hydrological geology?

"This time, a total of 12 rock tunnels were used to excavate the machine (hereinafter referred to as" TBM "). Among them, there were 6 in diameter of 9 meters. The localization rate of the equipment was more than 70%." Tell 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 excavation speed can reach 250 meters to 450 meters per month, which is drilling. Three to 5 times the explosive method.

Wang Dujuan pointed out that the biggest problem that may be encountered in the construction of the Guangdong Water Resources Configuration Project in Beibu Gulf is the fault crushing belt, and basically every TBM tunnel has a broken layer. "Some faults are twenty or thirty meters, it is easier; some faults are two or three hundred meters, which is a bit difficult. Now scientifically handle it from the design level. This reduces the risk of TBM being stuck. "

In the buried deep tunnel, TBM may also encounter hard rock explosion or soft rock deformation. The rock explosion may occur during the hard rock excavation process of stress concentration. The rock will pop up like a bullet, and the condition of the injured and injured equipment will occur. The problem that needs to be out of trouble. The depth of the depth of the Guangdong Water Resources Configuration Project in the North Bay is not 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.

According to Liu Yuanxun, in view of this, the research and design of tunnel lining structures are more difficult. If it cannot withstand pressure, it will cause major accidents: "For key difficulties in design, construction, operation and maintenance, we rely on scientific and technological innovation to focus on major technical problems. Research on scientific research, the "Outline of the Scientific Research Research Outline of the Guangdong Water Resources Configuration Engineering of the North Bay Bay" will be established, which will lay a solid foundation for the smooth construction of the project. "

The excavation speed of the excavation can reach 250 meters to 450 meters per month

Project faces world -class difficulties challenges

Covering the goal of water supply and flood prevention irrigation

Yangcheng Evening News reporter Xu Zhangchao and correspondent Yue Shuixuan reported: From the East Deep Water Supplying Project in the 1960s, to the current Pearl River Delta Water Resources Configuration Project, and the Guangdong Water Resources Configuration Project in Beibu Gulf. Water resources configuration backbone network, flood control safety network, Wanli Bidao network, rural water conservancy guarantee network, and smart water conservancy network, promote the province's water conservancy level to enter the first echelon in the country. 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 mountainous area of ​​Guangdong is mainly mountain tunnel, facing industry nature and even world -class difficulties and challenges." Project special experts, China, China, China, China, China Chen Xiangsheng, an academician of the Academy of Engineering, said in an interview that the project involves a variety of water sources and various users, covering the target of water supply, flood prevention, irrigation, ecology and other water resources. The efficient scheduling operation of the water circumference system requires multiple disciplines.

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, scientific planning is also avoided through scientific planning to avoid affecting the water ecological environment of the water regulation area and the water area along the line. Chen Xiangsheng said that the project's water port is located in the upstream of Sixian 滘. The project is less than 2700m^3/s (Si Xian's salty flow of 2500m^3/s+other water households in the lower reaches). Basically, it will not 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. Large, the water volume of river channels caused by retreating is slightly increased; after the project is implemented, water and groundwater can be returned by the water area to receive some river channels, which can further improve the water environment in the water area.

Starting scene that day

Guangdong Water Conservancy Construction "Tiger Power" is fully opened

Yangcheng Evening News reporter Xu Zhangchao and correspondent Yue Shuixuan reported: According to data from the Ministry of Water Resources, as of the end of July this year, the national construction water conservancy project reached 31,800, with an investment scale of 1.7 trillion yuan. In the same period, it increased by 71.4%; the construction of water conservancy projects was 1.61 million, of which 1.233 million were 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" high -quality water conservancy development blueprint. Among them, the water conservancy investment will be completed by more than 400 billion yuan during the "14th Five -Year Plan" period. This year, it is planned to complete the investment of 80 billion yuan above.

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%. It is full of horsepower and strives to run out of water conservancy construction "acceleration".

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.

Dreatment of water and wealth to quench thirst for enterprises empowerment development

Yangcheng Evening News reporter Quan Liangbo, correspondent Zhuo Jian Si and Chen Feihu reported: The Guangdong Water Resources Configuration Project (hereinafter referred to as the "Huanbei Project") is one of the 55 major water conservancy projects identified by the State Council. On the 31st, the Huanbei Project held a opening ceremony in Xinyi City, Maoming. After completion, it will Runze the 10 million people in western Guangdong to meet most enterprises' water needs. It is reported that in the process of promoting the project landing process, Maoming achieved city -level overall design and county -level leading promotion, and the two were integrated. In the future, the construction party integrates the experience of the Hejiang test section project into the project to complete the construction tasks with high quality.

Win the hearts of the masses with embroidery kung fu

Watching his orchard was flat, Liu Mingfang, a villager in Zhonghe Village, Guizi Town, Xinyi City, looked forward to it. "Building a water conservancy project is a good thing to benefit future generations, and 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 longed for the green fruit of the north project to mature as soon as possible to benefit western Guangdong. Nowadays, with the construction of the north project, a excavator has entered 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 204 kilometers, and the total length of the Xinyi section line is about 45 kilometers, accounting for 22%of the total length of Maoming section. It is the necessary line of Maoming and downstream areas to be the control line 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. 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 live examples, the people understood the significance of the project and cooperated with the land.

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. It is expected that the project is expected to be completed in 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

According to reports, after the completion of the project, it can optimize the regional water resources allocation pattern, further ensure the safety of production and live water, 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 reservoir of the western western western water resources, transforming from Maoming's "Life Reservoir" to a "western western water tower", and the water supply population has expanded from more than 6 million people to 10 million people.

In addition to satisfying daily life, the main thing is 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.

The relevant person in charge of the Maoming Water Affairs Bureau said that after the project is completed, it will greatly improve the water supply capacity of Maoming City, significantly improve the regional water ecological environment, and enhance the comprehensive carrying capacity of the west wing of the coastal economy and accelerate the construction of the "one core, one area, one area" area. The development pattern is of great significance.
