How does the South to North Water Diversion Project move the river upstream?

Through three water diversion routes, it is connected to the Yangtze River and the Yellow RiverHuai RiverThe connection with the four major rivers of the Haihe RiverThe overall layout with "four horizontal and three vertical" as the main body is formed, which is conducive to the realization of the rational allocation pattern of China's water resources from north to south and east to west. The construction of the western route has not yet begun.

The eastern route project is planned to divert water from the main stream of the Yangtze River near Yangzhou, Jiangsu Province, using the Beijing-Hangzhou Grand Canal.

and a parallel river to connect to Hongze Lake.

Luoma Lake, Nansi Lake, Dongping Lake, and as a storage reservoir, after the pumping station gradually lifts water into Dongping Lake, the water is divided into two roads.

After crossing the Yellow River to the north, it flows to Tianjin, and the main water transmission line from the Yangtze River to Tianjin Beidagang Reservoir is about 1,156 kilometers long; The other road connects to the Huangjiqing Channel through the newly opened Jiaodong water transmission trunk line to the east to supply water to the Jiaodong area. The South-to-North Water Diversion Project has created the world's largest pumping station group - the East Line Pumping Station Group Project, which is implemented in three phases.

Significance: 1. Solve the water shortage in the north;

2. Increase the carrying capacity of water resources and improve the efficiency of resource allocation;

3. Make the northern region of China.

Gradually become a water-saving and anti-pollution society with reasonable allocation of water resources and good water environment;

4. It is conducive to alleviating the constraints of water shortage on the urbanization development of the northern region and promoting the local urbanization process;

5. It is the Beijing-Hangzhou Canal.

The year-round navigation of the Jining-Xuzhou section ensures the water source. Make Luxi and Subei.

The two commercial grain bases have been consolidated and developed.

In fact, water cannot go upstream, unless human intervention is carried out, and it seems that the south-to-north water diversion project is to let the water go upstream, but in fact, a lot of scientific research work is still carried out in the place where the water is taken. It is ensured that the water is definitely higher at the source than at the end.

Our country mainly uses pumping machines and hydraulic tools to achieve this treatment method of the South-to-North Water Diversion, and when the water encounters obstacles from the bottom up when passing through certain valleys, hydraulic tools are needed at this time, which can effectively guide the water from the low to the high places.

That is to use the principle of some straws, slowly let the water go up, you can pump it to the place where the water is needed, so that the problem of drinking water can be solved.

Let the water go upstream, because their water flow is greatly adjusted, and the amplitude of this up and down is also adjusted, so let the river flow upstream, to achieve a very impactful kind of picture.

It has been seven years since the South-to-North Water Diversion Project was opened to water, and in the process of construction, this great project has gone through a bumpy process such as the construction of a U-shaped aqueduct, the crossing of the Yellow River, and the protection of cultural relics along the way. These problems slowed down the pace of construction, but did not stump the engineers, and through the efforts of all staff, they finally overcame the difficulties and obstacles, so that the water of the Danjiang Estuary flowed smoothly to Beijing.

As a water conservancy person, I had the honor to visit the construction site of the Turbulent River Aqueduct. At that time, I was still a student, and when I saw the construction of the huge aqueduct, my heart was full of shock. Through the teacher's explanation and video materials, I also learned about the miracle of the South-to-North Water Diversion Project, and the ups and downs experienced in the construction process.

The construction of the Turbulent River Aqueduct has created the world's largest history. The aqueduct has a U-shaped design, with an inner diameter of 9 meters and a span of 40 meters for each section. The weight of such a reinforced concrete behemoth reached 1,600 tons, which is equivalent to the weight of thousands of cars if described as a car.

Such a weight made how to build the U-shaped aqueduct a difficult problem in front of the engineers. There is no problem with the prefabrication process, the difficulty lies in the hoisting, there is no hoisting equipment, and such a weight behemoth can be lifted.

In the end, a large-scale slotting machine was designed, and the aqueduct construction task was completed by cast-in-place concrete.

The South-to-North Water Diversion Project was constructed, passing through many mountains, rivers and cities along the way, and using the method of drilling holes in mountains and building bridges to meet water. Among the many obstacles, only the Yellow River is the most troublesome. The width of the river and the silt on the riverbed made the engineers worry about wearing yellow.

After many arguments by many engineers, it was finally chosen to cross the Yellow River from below, rather than build piers and erect an aqueduct above. The Yellow River piercing project uses a large shield machine to cross the shield from 30 meters below the riverbed of the Yellow River. With the efforts of the engineers, it took more than 500 days and nights to penetrate the Yellow River, leaving behind two giant tunnels with an inner diameter of 7 meters.

During the construction of the whole project, the ups and downs experienced were far more than these two. Instead of stumbling down on the engineers, many bumps in the road inspired them to overcome the challenge.

The middle route of the South-to-North Water Diversion Project starts from the Taocha Canal in Xichuan County, Henan Province, and goes all the way to the north. This artificial water vein has encountered a huge test in Henan Province - expansive soil. From the head of the canal to Tuancheng Lake in Beijing, the 1,277-kilometer-long middle trunk line project has nearly 400 kilometers of channels to pass through the expansive land area.

The expansive soil (rock) canal section in our province is 340 kilometers long, accounting for 46% of the length of the trunk line in the territory, of which the Nanyang expansive soil section is one kilometer long, accounting for the total length of the Nanyang section.

It has suffered many difficulties, has many special geographical environments, and has many technical problems, which require a lot of energy, manpower and material resources.

<> water from the South-to-North Water Diversion Project flows through the middle line of the dry shed wheel to the North China Plain, and finally flows to Beijing, Tianhe, and Jiejin.

The eastern route flows to the eastern part of the North China Plain, and finally flows to Jinan, Qingdao, Weihai and Tianjin in Shandong Province.

The South-to-North Water Diversion Project starts from the Jiangdu Water Conservancy Project in Yangzhou, Jiangsu Province, and ends in the eastern part of the Huang-Huai-Hai Plain, the Jiaodong region and the Beijing-Tianjin-Hebei region. The South-to-North Water Diversion Project is a strategic project in China, which was conceived in 1952 and has a total length of 4,350 kilometers of eastern, central and western trunk lines.

After analyzing and comparing more than 50 options, the water transfer programme has yielded a large number of valuable results. The planning area of the South-to-North Water Diversion Project involves a population of 100 million people, and the scale of water diversion is 44.8 billion cubic meters. The total length of the eastern, central and western trunk lines planned by the project is 4,350 kilometers.

The total length of the first phase of the east and middle lines is 2,899 kilometers, and the first-level supporting branch canals of six provinces and cities along the line are about 2,700 kilometers.

In September 2012, the relocation of migrants from the Danjiangkou reservoir area of the middle route of the South-to-North Water Diversion Project was fully completed. The South-to-North Water Diversion Project mainly solves the problem of water shortage in northern China, especially in the Huang-Huai-Hai Basin, with a population of 100 million people in the planning area. There are three water diversion routes, the eastern, central and western routes, which are connected with the four major rivers of the Yangtze River, the Yellow River, the Huai River and the Haihe River through the three water diversion routes, forming an overall layout with four horizontal and three vertical as the main body, so as to facilitate the realization of the rational allocation pattern of China's water resources from north to south and east to west.

YesFrom June 7th to July 9th, the middle line project implemented summer ecological water replenishment to many rivers in Hebei Province, such as the Hutuo River and the Daqing River, and the total water supply of the total trunk canal of the middle line reached 100 million cubic meters. This water replenishment has helped the ecological environment of the Hutuo River, Puhe River and Nanjuma River to continue to improveThe Ziya River, the Ziya New River and other rivers that have been cut off have come back to life

After replenishing water, the Hutuo River is gurgling and sparkling. Compared with before the replenishment in 2018, the groundwater level has risen by one meter within 10 kilometers on both sides of the Hutuo River. The good water environment has brought about ecological changes, and the vast water surface of the Hutuo River effectively regulates the temperature and humidity on both banks, with the temperature regulation at about 4 and the humidity regulation exceeding 20%, and the ecological backfill effect is obvious.

Shijiazhuang City has launched a series of projects such as the comprehensive improvement project of the Hutuo River and the ecological restoration project of the Hutuo River.

Methods for ensuring water supply security in the middle route project

In order to ensure the safety of water supply, the middle line project uses high-tech means to build an automatic dispatching gate control system to realize the automatic collection of dispatching information such as water level, flow rate, gate opening and remote automatic control of various gates.

Combined with the water conditions and working conditions of the whole line, the dispatching instructions are scientifically formulated and issued, and the dispatching agencies at all levels accurately carry out water transmission scheduling. "Unified scheduling, centralized control, and hierarchical management" have realized the automation of the water transfer process, the visualization of remote monitoring, and the informatization of operation and maintenance management.

What should I do if the "South-to-North Water Diversion" of the Century Project encounters natural rivers? Real shot of "Water Bridge".

This has a lot to do with the distance, if you choose the south-to-north water diversion, it will reduce a lot of expenses, and the distance will be much shorter, plus the main water source of Heilongjiang still comes from the rain, generally in the summer, so it is particularly uniform, and the amount of precipitation is also a lot, the latter reason is because of the subsidence, so the south-to-north water diversion will be chosen.

This is because the water resources in the north are relatively scarce and they are simply not enough, so it is impossible to have a water source that flows from the north to the south.

Because the south is prone to flooding, while the north is very dry, it is necessary to transfer from the south to the north, which can solve the problem in two aspects.
