The Chinese nation has always been a nation full of wisdom, and in the past 5,000 years, the working people have created countless miracles, and the Yangtze River Dam is one of them!
The Yangtze River is known as the "roof of the world", the river is turbulent, and the altitude difference is large, so the difficulty of building a dam is not low. Zheng Shouren, an engineer at the time, had been building the dam since the end of the last century, and at the beginning of its construction, he found that the Yangtze River was too fast, the terrain was rugged, and the surrounding arc-shaped mountains were very different in terms of geology and topography, so he thought hard about how to solve them.
After constant experimentation and discussion, the effort paid off, and he found detailed measures to overcome the difficulties. Based on this,He spearheaded the construction of a waterwayto drain water and reduce the impact of water flow, improving the safety of dam construction. After this, he was in the river channelBuild a small stronghold and close the right waterfront with stones
This approach is more complicated to operate, but it directly reduces the water area of the Yangtze River and improves the efficiency of dam construction. Not only that, this operation has the effect of cutting off the main stream and discharging the flood, and even if the flood season comes, the danger is greatly reduced.
Finally, under his leadership, the team based on the stronghold built earlierClosing the Yangtze River little by little。Therefore, even though the scientific and technological conditions at that time were far inferior to today's, and the number of machinery and equipment was not more than Er, the dam could still be successfully built with the wisdom of the working people. But after all, building the dam is a huge project, and it still took several years.
Facts have proved that this construction method is a correct construction method that conforms to the development of the time and meets the needs of the people, which is worthy of praise.
-
Changing the tributaries of rivers and diverting them from the south to the north is the same project.
-
If you want to cut it off, you have to build a very strong promotion.
-
The construction of the project is a complete and perfect construction plan, and the construction of the Yangtze River Dam is also based on the construction plan.
-
I think it's hard to cut it off, but I could have led it to another place.
-
The working people cut it off little by little with their own hands and sweat.
-
I feel that the water is ruthless, and if I want to cut off the rapids of the Yangtze River, I can only change the direction.
-
This can't be robbed, it can only be changed, such as rerouting him.
-
I think there's water there, and we can only get him to divert a lot of things.

No. The waters governed by Dayu were the Yellow River, the Yangtze River, the Huai River and the weak water that flowed into the desert.
Dayu (鲧禹治水) is an ancient Chinese myth and legend, the famous legend of the Great Flood in ancient times. He is a descendant of the Yellow Emperor, during the period of the Three Emperors and Five Emperors, the Yellow River flooded, and the father and son of Kun and Yu were ordered by the two emperors of Yao and Shun, and Ren Chongbo and Xia Bo were responsible for water control.
Dayu led the people to fight against the flood in the natural disaster, and finally won the victory. In the face of the surging flood, Dayu learned a lesson from the failure of Kun to control the water and changed"Blocked"The method of rushing and trousers to channel the flood shows that he has the wisdom to lead the people to overcome difficulties; In order to control the flood, Dayu has been fighting with the people for many years, ignoring personal interests"Sansanjian passed the door without entering"。Dayu has been controlling water for 13 years, exhausted his hard work and physical strength, and finally completed the great cause of water control.
-
The story of Dayu's water control is well-known, and the main treatment is the flood: the Yellow River.
During the period of the Five Emperors, the floods in the Yellow River basin were particularly serious, and the people were often displaced because of the floods, and the dealers had no harvest. By the time of Yaoshun, the flow of water in the Yellow River basin was even more unstable, and it had reached a situation where it was incurable.
The Yellow River is one of the longest rivers in the world and the second longest river in China (also known as the second largest river). The total length of the Yellow River is about 5,464 kilometers, and its basin area.
People's Daily Online: about 752443 square kilometers, and the Ministry of Water Resources's "Yellow River Network" recorded as: the total area of the basin is 10,000 square kilometers (including the area of the inland basin area of 10,000 square kilometers). The basin has long winters and short summers, and the temperature difference between winter and summer is huge, and the seasonal temperature changes are distinct.
The Yellow River originates in the Yougu Zongliezi Socks Basin at the northern foot of Bayankala Mountain on the Qinghai-Tibet Plateau, flows from west to east through nine provinces (autonomous regions) of Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan and Shandong, and finally flows into the Bohai Sea. The precipitation in the basin is small, mainly dryland agriculture, dry in winter and dry in spring, and the precipitation is concentrated in summer, autumn, July and August.
The middle and upper reaches of the Yellow River are mainly mountainous, and the middle and lower reaches are dominated by plains and hills. Because the middle section of the river flows through the Loess Plateau region of China, it carries a large amount of sediment, so it is also known as the river with the most sediment content in the world. But in Chinese history, the diversion of the lower reaches of the Yellow River has had a huge impact on human civilization.
The Yellow River is the main birthplace of Chinese civilization, and the Chinese call it the "Mother River". Every year, 1.6 billion tons of sediment are carried, of which 1.2 billion tons flow into the sea, and the remaining 400 million tons remain in the lower reaches of the Yellow River for many years, forming an alluvial plain that is conducive to cultivation.
The Yellow River Basin is the earliest developed region in China. When most of the world was still in a state of ignorance, our industrious and brave ancestors cut thorns, cleared grass, and worked in this vast land, creating a splendid and dazzling ancient culture.

China is an ancient civilization and has built many amazing immortal buildings in history, such as the Terracotta Warriors and Horses of Qin Shi Huang, the Great Wall, Dujiangyan, etc., which have amazed the world to this day. In modern times, our country has become stronger and stronger, and the Three Gorges Dam on the Yangtze River has been built to amaze the world. Then today I will talk to you about the Three Gorges Dam of the Yangtze River in China:
Our Three Gorges Dam on the Yangtze River is definitely a high-energy existence, which can not only prevent flooding, but also release water at the right time, and integrate water and electricity.
Although the controversy over whether the Three Gorges Dam can be demolished or not is very big, we must also face up to the Three Gorges Dam and those who pay. The Three Gorges Dam, located in Sandouping Town, Yichang City, Hubei Province, China, is the largest hydropower project in the world. The height of the dam is another 185 meters, the total length is about 3,335 meters, the total investment is more than 90 billion yuan, started in 1994, and completed in 2002.
China has spent a lot of human resources on it, which shows the importance it attaches to the Three Gorges Dam on the Yangtze River. Some people are curious about the fact that the Yangtze River is rolling and flowing, but how was the Three Gorges Dam built on the Yangtze River? It is said that the water speed of the Yangtze River is very fast, and the Three Gorges Dam can be built on the current of thousands of zhang, then you have to admire the wisdom of Chinese engineering architects. In the past, to build a dam in China, it took time, place, and people. That is, the waterless area, the area with better weather and more manpower is built.
Now our Three Gorges Dam on the Yangtze River is built in water, and the weather is changeable, which shows that it is still difficult to build. At that time, the chief engineer Zheng Shouren persevered in leading his team to build, he first sorted out his thinking, built from a geographical point of view, put down the traditional construction methods that were not in harmony with reality, and divided the Yangtze River into three parts, the left bank, the middle bank, and the right bank. Chief engineer Zheng Shouren chose a bag-shaped Yangtze River area on the left bank according to the terrain conditions, and used professional tools to fill the stones into the river to increase the height of the riverbed.
It is this flat mat scheme that is used to do a good job in the dam foundation of the Three Gorges Dam on the Yangtze River. In addition, the increased hardness has laid a solid foundation for future dam construction and reduced the damage caused by water flow. Starting from the middle section, the water of the Yangtze River will be directed to the left and right banks, the central part will be monopolized, the water of the Yangtze River will be drained in the middle, and then the construction of the dam in the middle of the middle will begin.
After the completion of the middle bank, the left bank was intercepted, and the middle and right banks were released into open channels, and the left bank dam was built. After the dam is repaired on the left bank, it is the right bank, in order, in order, in the middle, on the left bank, on the right bank.
This great project was finally completed in 2006. Zheng Shouren used his wisdom to complete the difficult task, win glory for the country, benefit the people, and bring the wisdom of the Chinese to the extreme. And we should thank all the engineers and construction workers who participated in the construction of the dam, respect their achievements, and use their blood and sweat to build the Three Gorges Dam on the Yangtze River.

It is impossible to completely cut off the Yangtze River rapids, when the Three Gorges Dam is built, first of all, we must build a drainage canal, which is the basis for the construction of the Three Gorges Dam, although there are certain difficulties, but compared with the task of cutting off the main stream of the Yangtze River, that is, pediatrics, if you can't cut off the Yangtze River rapids, then the whole project can not be carried out, the left bank of the Three Gorges Dam site is a protruding mountain, the right bank is an arc-shaped mountain, it is very difficult to intercept the Yangtze River at that time, the water depth of the main interception area reaches more than 60 meters, The water speed of the Yangtze River reaches 4 meters per second, and it is difficult for the thrown stone to reach the target area smoothly, the chief engineer Zheng Shouren led the team to face the difficulties, in order to solve the problem of difficult stone delivery, the design team designed a flat throwing bottom feeding scheme, to the effect that the stone can be successfully sunk through special tools, and the hardness of the riverbed at the bottom of the river can be improved through this scheme.

The Three Gorges Dam was built to cope with the Yangtze River rapids by building a diversion canal that would enclose part of the water on the right bank, connect the stronghold with the left bank, and finally connect the dam with stones.

I think that when building, we must repair it in a partition, not in large quantities, and we must control the amount of water and water speed.

When it comes to water, everyone should be familiar with it. More than half of our body is water; More than seventy percent of the planet is water. In daily life, we need to drink water, we need water to water our plants; In nature, water is used to nourish all things; Water plays a vital role in our survival and livelihood.
That's right, not only is it somewhat well-known in the world, but articles about it have been included in textbooks. It can be said that the establishment of the Three Gorges Project has benefited many people. The most direct should be for the residents of the middle and lower reaches of the Yangtze River, and its establishment is a great blessing for the residents.
Because of its establishment, the losses caused by waterlogging are greatly reduced. So some people can't help but wonder: how did the Three Gorges Dam be built when the Yangtze River is so turbulent?
After reading the long knowledge, don't worry, let me answer it carefully for you.
First of all, to build a dam, the first thing to do is to cut off the flow of water from the Three Gorges in the middle to form a north-south diversion. Then the water in it is drained, a river channel is built in the middle, and then the river is filled with enough stones on both sides until the stones can cover the surface of the water, so that the water flows to the other side, and after the water is drained, it becomes a dam. Then build the other side and you're done.
Although it is only a few sentences of textual description, it is not easy to implement it. Every step and every place is a key point, and it takes a lot of money, manpower and material resources to invest. Moreover, the Three Gorges has a large drop and the river is turbulent, which makes it even more difficult to build.
In fact, not only the Three Gorges, but also many dams were built little by little. While admiring the greatness of the Three Gorges Dam, we also express our sincere respect to the builders of the Three Gorges Dam, believing that without their wise minds and industrious hands, there would be no Three Gorges today, and we would not have seen such a great construction.
The completion of the Three Gorges is conducive to improving shipping in the upper reaches of the Yangtze River, reducing natural disasters in the lower reaches, and helping China to increase the supply of electricity. There are so many benefits for both the country and the individual.
In the past, I only knew that the Three Gorges had beautiful scenery and was a must-visit destination for tourism, but I never imagined that its construction was so difficult. Perhaps we do not realize that the completion of the Three Gorges will have such a great impact on our production and life.

When the Three Gorges Dam was built, how did it stop the surging river? It's an eye-opener to watch!

1. The Tuotuo River is the positive source. The south source is Dangqu, and the north source is the Chumar River.
2. The Jingjiang section of the Yangtze River is bent, tortuous, low-lying, the flow rate is slowed, the water flow is not smooth, and the sediment is silted, which raises the riverbed and forms an above-ground river, and the precipitation in the basin is large, which is easy to cause floods.
3. The Jingjiang section of the Yangtze River is "artificially cut and straightened to strengthen the dam."
4. Due to the aridification of the climate and the impact of the water storage of the Three Gorges Reservoir, the amount of water entering Dongting Lake has decreased seasonally, the water level in the lake area has decreased, and the drought period has been extended. The population has increased, the surrounding agricultural production activities have increased, a large area of land has been enclosed around the lake, and the water resources have been used inappropriately.
Dongting Lake has a historically low water level.

1.It originates from the main peak of the Tanggula Mountains at an altitude of 6,621 meters above sea level on the Qinghai-Tibet Plateau, and the Jianggendi Ru Snow Mountain on the southwest side of the Gradan Winter Snow Mountain.
2.Jingjiang, nine curved loops.
Thousands of miles of the Yangtze River, the danger is in the Jingjiang River. You can see from the map that the Jingjiang section is W-shaped, the river channel is narrow, the water volume is large, and the river channel is curved, and because of the siltation, the riverbed is raised and becomes an above-ground river, so the drainage is not smooth, and it is easy to flood.
3.Jingjiang. 4.The water area of Dongting Lake has decreased, and the wetland area has shrunk.
Enclosing lakes to create fields, sediment accumulation, etc.
Cattle. Dayu.
Water control (鲧禹治水) is in ancient China. >>>More
OneAccording to relevant data, the area of Dayu's water control at that time was about the east of Hebei and the east of Henan, the west and south of Shandong and the north of the Huai River. This is because these areas are subject to frequent flooding. This is also a legend that many ethnic groups have been flooded. >>>More
Because Dayu has the feat of saving the world, he left his family to control the water in order to keep the people away from the flood, such a "first world worries and worries" people are naturally admired and loved by people from generation to generation.
Without Dayu to control the water, our country does not have a "Kyushu" said. When it comes to various legends in ancient China, it is really "countless", even as vast as a sea of smoke. One of the most famous, is the ancient period of the sage Dayu, bold "Yu to control the water", this is not only a long-standing story in the ancient Chinese mythological system, but also recorded in the official history of the "Historical Records", it can be seen that Dayu in history, is also a senior "human emperor". >>>More
It's not the Nile, because the Nile is all in Africa, Dayu at that time, and in Asia, it can't go to Africa to govern the Nile.
