If one day Three Gorges Dam "dead in life", what will we face? Today's Three Gorges Dam obviously has an important role in flood regulation and flood control in the middle and lower reaches of the Yangtze River . How many years can it last?
Three Gorges Dam is currently one of the largest concrete water conservancy projects in the world , and is well-known. 's total construction investment reached hundreds of billions of yuan and a total installed capacity of 22.5 million kilowatts. As a concrete gravity dam, the Three Gorges Dam has entered the period of high-speed construction since 1999. The annual concrete pouring volume can reach millions of cubic meters, setting world records many times. The dam body of the entire dam is extremely thick.
However, despite this, Three Gorges Dam is still a concrete building after all. At present, the lifespan of general concrete building construction in China is basically around 70 years. Buildings that exceed their service life will have certain risks and safety hazards.
, and the general concrete gravity dam may have a service life of less than a hundred years. If it exceeds its service life, it has to be demolished or rebuilt and reinforced. However, as a century-old project, the Three Gorges Dam has reached a high standard rare in the world.
used superb concrete pouring technology during its construction process, and coupled with its huge size, many experts in my country have publicly stated that the service life of the dam can reach more than one hundred years. Some people even believe that as long as it is maintained and repaired in time, the service life of the Three Gorges Dam can even reach 500 years.
In order to extend the service life of the Three Gorges Dam, my country has also taken corresponding effective measures. For example, repairs and reinforces dams , which has always been a very practical method. As early as more than two thousand years ago, the Dujiangyan water conservancy project was built in Sichuan, my country. Over the years, Dujiangyan has undergone many repairs and reinforcements, and this project is still in use today. Therefore, regular maintenance of the Three Gorges Dam is an important way to extend its service life.
In order to make the Three Gorges Dam have excellent quality, the country is also very strict in its entire construction project. On January 3, 1993, the State Council specially established the Three Gorges Engineering Construction Committee of the State Council to supervise and manage the project in a timely and effective manner. In 1999, according to the recommendation of China Three Gorges Corporation, the Three Gorges Construction Committee of the State Council decided to form a quality inspection expert group for the Three Gorges Hub Project to check the overall structural safety and construction of the Three Gorges Project to ensure that the completion of the Three Gorges Project is foolproof to the greatest extent.
However, even if we take sufficient measures, the Three Gorges Dam will eventually have a day of "dead". So if the Three Gorges Dam is really aging and cannot be repaired, how should we deal with it?
In fact, there is no need to worry about this, because although the construction of the Three Gorges Dam is not a one-time and for all, my country is now very advanced in the construction and maintenance technology of large-scale projects such as dams. Even if that day really comes many years later, our is fully capable of choosing a new dam site near the dam, carrying out a brand new construction, and building a brand new Three Gorges Dam, allowing it to continue to protect the safety of people's lives and property in the middle and lower reaches of the Yangtze River. at that time, the Three Gorges Dam can be safely removed.
So what impact will the Three Gorges Dam have on our country if it is demolished? In fact, we can think about it the other way around and see what benefits the Three Gorges Dam has brought to us today.
First of all, the Three Gorges Dam can emit hundreds of billions of kWh of electricity per year. These electricity is transported to various regions, promoting the development of my country's economy, reducing the use of coal, and making a significant contribution to protecting the environment.
Secondly, the completion of the dam has also created a unique landscape of "High Gorges Out of Flat Lake" . Combined with the magnificence of the dam itself, the Three Gorges Dam has been open to the public as a scenic spot after its completion, providing tourists with visits, and promoting the development of the local tourism industry.
Another most important point is that The Three Gorges Dam can withstand extremely high pressure with its solid concrete structure. When in the middle and lower reaches of the Yangtze River encounters flood disasters, the Three Gorges Dam can intercept the flood peak and discharge the flood after the flood peak fades. After the construction of the Three Gorges Dam, the number of floods in the middle and lower reaches of the Yangtze River decreased.
It can be seen that the Three Gorges Dam has brought quite a lot of "welfare" to the people of our country, and it even affects the lives and property safety of countless people.
It is precisely because the Three Gorges Dam plays a crucial role in our country that many foreign ill intentions have threatened that as long as they throw a bomb at the Three Gorges Dam, they can destroy it, causing tens of millions or even hundreds of millions of people in the middle and lower reaches of the Yangtze River to be hit by devastating floods, so that they can "win without fighting." However, their ideas are just "daydreams".
The solidity of the Three Gorges Project is not as weak as they imagined. In order to ensure that the Three Gorges Dam has the ability to withstand bombs, our country has conducted many explosion experiments on it, and experiments have also shown that ordinary bombs cannot hurt the Three Gorges Dam at all! Even if you use the nuclear weapon , it cannot cause devastating damage to the dam. At most, only blows up a gap in the structure of the large dam, and the overall structure of the dam is still very solid and stable.
In addition, near the Three Gorges Dam, troops are stationed all year round to prevent some unexpected situations. After all, the Three Gorges Project has now become an indispensable project in the normal operation of the country. Therefore, we don’t have to worry about the Three Gorges Dam being blown up even if one day the war comes.
There have been mixed controversies about the Three Gorges Dam over the years, but it is undeniable that its construction does outweigh the disadvantages. Moreover, with the development of China's economy and the continuous growth of electricity consumption, the Three Gorges Dam is also playing an increasingly important role. To this day, the Three Gorges Dam is still a "Chinese Aegis Shield" in the middle reaches of the Yangtze River, defending the people on this land at all times and benefiting the future.
