Preface
The Yellow River, the mother river of the Chinese nation, gave birth to Chinese civilization and nourished the land of China, however, in this ancient river, an astonishing discovery made people jaw-dropping.
Around 2018, when a careful netizen was enjoying the beautiful scenery by the Yellow River, he suddenly found that a large pit with a depth of 5 meters appeared at the bottom of the river!
As soon as the news broke, it immediately sparked widespread concern and speculation, with some fearing that it was man-made destruction, some people speculating that it was geological changes, and some people were worried that it would affect the ecological balance of the Yellow River.
However, the truth is often more unexpected than imagined, and this seemingly dangerous "big pit" actually hides a huge "treasure" that benefits 1.4 billion Chinese!
Far from being sabotage, it is an important part of another shocking water conservancy project in China, which is so large and far-reaching that even developed countries like the United States and Japan have cast envious glances.
What kind of project can create such a huge "wound" at the bottom of the Yellow River? How will this "treasure" benefit hundreds of millions of people?
The mysterious "treasure" at the bottom of the Yellow River
When the news spread, people speculated about the origin of this mysterious crater, some worried that it was a geological disaster, and some suspected that it was man-made sabotage. But the truth is unexpected, this "big pit" turned out to be part of an important water conservancy project!
That's right, this is the high-profile Han-Ji-Wei project, the purpose of which is to divert water from the Han River to the Wei River and solve the long-standing problem of water shortage in the northwest region.
You know, between the Han River and the Wei River, there is the Qinling Mountains! It wasn't something that could be crossed casually, but the engineers racked their brains and came up with a bold plan.
They want to open a 98.3-kilometer-long tunnel under the Qinling Mountains! This tunnel is the core of the whole project - Qinling Water Conveyance Tunnel, it can be said that this tunnel is the "lifeline" connecting the north and the south.
The Qinling Mountains have complex geology, hard rocks, high temperatures, and the possibility of sudden water surges and landslides, which is simply a contest with nature!
In order to overcome these difficulties, the engineers worked hard to develop a special TBM, which is affectionately known as the "pangolin" by the workers.
Don't look like a "dragon", it's really good at work, but even so, the digging speed is not fast, and it can dig about 150 meters a day at most.
The temperature in the tunnel was as high as 40 degrees Celsius, the humidity was 90%, it was like a steamer, and the workers sweated profusely every day, but no one flinched.
After 8 years of hard work, this "tunnel of life" has finally been opened.
It not only solves the local water problem, but also promotes economic development and improves the ecological environment.
The pinnacle of China's water conservancy projects
Speaking of the Han-Ji-Wei diversion project, we have to mention its "big brother" - the South-to-North Water Diversion Project, which is a great project and can be called the "pinnacle" of China's water conservancy industry.
The idea of transferring water from the south to the north, as the name suggests, is to transfer water from the south to the north, which sounds simple, but it is not easy to do.
However, we Chinese just don't believe in evil, since there is a shortage of water in the north, then find a way to send water over, so after nearly 50 years of repeated demonstrations, this huge project was finally officially launched in 2002.
The project is divided into three lines: the east line, the middle line and the west line, the east line and the middle line have been opened to water one after another, and the water can be sent north as much as more than 20 billion cubic meters every year, what is the concept? That's the equivalent of sending 800,000 standard swimming pools to the north every year!
In order to make the water "swim upstream", the engineering team has made great efforts, and 52 pumping stations have been built, which are among the best in the world.
Moreover, in order to reduce the cost of later maintenance, the open-pit river channel is also boldly adopted, and these innovations reflect the wisdom of Chinese engineers.
The South-to-North Water Diversion Project not only solves the water problem of 150 million people in the north, but also alleviates the ecological crisis caused by the interruption of the lower reaches of the Yellow River.
Where is this project, it is simply a modern version of "Dayu water control"! Our ancestors were able to deal with floods, and our generation was able to solve the problem of water shortage, which is the endless wisdom of the Chinese nation.
The Han-Ji-Wei diversion project is actually the "little brother" of the south-to-north water diversion, and they all have a common goal, that is, to make water resources more balanced, so that every Chinese can drink clean water.
Having said that, from the initial discovery of the "big pit" at the bottom of the Yellow River, to the understanding of the entire Han-Ji-Wei diversion project, and then to the "big brother" of the South-to-North Water Diversion, we see the grand blueprint of China's water conservancy projects.
The miracle of China's water conservancy projects
The project is divided into three parts: the Golden Gorge Water Conservancy Hub, the Sanhekou Water Conservancy Hub and the Qinling Water Conveyance Tunnel.
The Golden Gorge Water Conservancy Project is the "dragon" of the whole project, and its mission is to draw water from the Han River, but the problem is that the water level of the Han River is more than 100 meters lower than that of the Sanhekou Reservoir.
So the engineers built a super pumping station here, which can pump 70 cubic meters of water per second, which is equivalent to filling a standard swimming pool in 3 seconds!
The Sanhekou Water Conservancy Hub is the "transfer station" of the whole project, which can supply 500 million cubic meters of water per year, just like a regulator, storing more water and releasing water when there is less water to ensure the stability of downstream water use.
The Qinling Water Conveyance Tunnel is the "aorta" of the whole project, and the 98.3-kilometer-long tunnel crosses the Qinling Mountains, which is not ordinarily difficult.
During the construction process, the engineering team encountered 7 landslides and 4 serious water surges, but our engineering team was stunned and there were no casualties! This safety record is among the best in the world.
China's water conservancy projects from an international perspective
China's water conservancy projects often impress the world, and even developed countries such as the United States and Japan can't help but cast envious glances, and even sigh "why don't you have it?"
The United States claims to be the "world's policeman" and is busy meddling with other people's affairs all day long, but their own infrastructure is very rotten! Except in the city center, where you're hard-pressed to see buildings over 10 floors, public facilities are dilapidated, and the subway is so dirty that even the Americans themselves complain.
The most laughable thing is the power facilities in the United States, power outages are commonplace in the United States, the power facilities are seriously aging, and they are vulnerable to extreme weather, but the US government does not care about it, and spends all its money on the military.
In particular, bridges in the United States are notoriously unreliable, and collapse accidents occur frequently, and the reason for this is because of insufficient investment funds and lack of talents.
You must know that Japan was a strong infrastructure power in the last century, and now there are obvious signs of decline, and they have spent a lot of time and money on "land reclamation", but the result is very little.
On the other hand, since the beginning of the 21st century, the speed of infrastructure construction can be described as rapid progress, high-rise buildings are lined up one after another, and the countryside is also changing with each passing day, even the most remote mountainous areas can pull power lines and erect signal towers.
The Hong Kong-Zhuhai-Macao Bridge and the Sichuan-Tibet Railway are all shocking projects, and the highway network and high-speed rail network are closely connected all parts of the country, making it convenient to travel, and the people's sense of happiness is also rising.
However, we still need to be clear that although we have made great achievements in infrastructure, we still have a long way to go in some areas, such as environmental protection and sustainable development, and we still need to continue to work hard.
From the South-to-North Water Diversion Project to the Han River to the Wei River, all of them are world-class projects, which not only solve our water problems, but also improve the ecological environment and promote economic development.
We Chinese have such a strength not to admit defeat, no matter how difficult the project, we must gnaw down, no matter how big the difficulty, we must overcome, this spirit is our most precious wealth.
epilogue
A mysterious "big pit" at the bottom of the Yellow River has unveiled the mystery of the Han-Ji-Wei project, and this seemingly dangerous "big pit" is actually an important part of a water conservancy project that benefits tens of millions of people.
From the diversion of water from the Han River to the South-to-North Water Diversion, we have seen the grand blueprint and amazing technical strength of China's water conservancy projects, which not only meet the people's water needs, but also improve the ecological environment, promote economic development, and truly achieve the goal of benefiting hundreds of millions of people.
China's infrastructure miracle, especially its achievements in water conservancy projects, has attracted worldwide attention and admiration, and even developed countries such as the United States and Japan have cast envious eyes on China's infrastructure strength, which fully proves China's leading position in this field.
However, we should not be complacent because of this, on the contrary, we should continue to carry forward the spirit of hard work and innovation, and continue to move forward on the road of infrastructure construction.
Let us be proud of China's infrastructure achievements, but also continue to work hard, create more miracles, contribute to the prosperity and development of the motherland, I believe that in the near future, we will be able to see more Chinese projects that amaze the world!
