Chapter 246 The Water Conservancy Project Inherited for More than 2000 Years Comes Out... (Subscribe)
"It's late, let's go into the water today."

"Teacher Chen Fan is here."

"It is estimated that there is still not much hope."

The crowd sighed.

But think about it too.

It is really hard to find water conservancy projects more than 2000 years ago.

You said that on land, maybe there is still this possibility.

But in the water... Not to mention the changes in the terrain, even the erosion of the Minjiang River for thousands of years may also be damaged.

just.

Just when everyone thought there might not be much to gain today.

Chen Fan, who had just surfaced, exclaimed excitedly: "I found it, I found the Dujiangyan ruins."

As soon as the voice came out.

There was a bang in the live broadcast room.

"found it?"

"Damn, did you really find it?"

"Oh my God……"

Although everyone does not know exactly what kind of water conservancy project Dujiangyan is.

But I heard from Chen Fan before that it is because of Dujiangyan that Shu has become a land of abundance.

want to come.

At that time, Shu land did not have the current conditions, and such water conservancy projects could change the situation of the entire Shu land.

If we can really reproduce the style of Dujiangyan at this moment, not to mention other things, I am afraid that the situation of flooding once every ten years will be solved.

"Teacher Chen Fan, did you find it?"

"Ah."

Standing on the boat, Chen Fan said: "Just now when I went into the water, I found several raised places...I think this is the Dujiangyan 2000 years ago."

"By the way, I also brought some dirt out."

"Great."

Jiang Wanli was also very excited at this time, and said: "Mr. Chen Fan, you should rest first, and we will send people down tomorrow."

"Not tomorrow, I'll go into the water later."

"Ah, Teacher Chen Fan, it's almost dark."

"It's okay, I'll turn on the lights in a while, I want to find out the situation under the water. In addition, I also want to ask relevant experts to confirm..."

"Let's rest for a while."

"No."

Chen Fan still shook his head: "Dujiangyan is related to the survival of tens of millions of people in Sichuan, and no one knows when another flood may occur. Although there was one last year, no one can guarantee whether it will happen again this year. The sooner we confirm, the sooner we can work out a specific plan.”

"This……"

Although it's getting dark now.

But seeing Chen Fan's incomparable determination, Jiang Wanli gritted his teeth and said, "Teacher Chen Fan, today I will fight here with you until dawn."

As he said that, Jiang Wanli said loudly again: "Hurry up and invite archaeological experts to enter the site."

Such a scene also caused everyone in the live broadcast room to fight their blood.

"I'm going to go, this scene, I instantly ignited."

"Me too. Once Dujiangyan is discovered, it will be a miracle in China's water conservancy engineering for thousands of years."

"It's so burning, so exciting, Mr. Chen Fan, you are our role model."

Stars flashed in everyone's eyes.

No matter how sane they were before, no matter how bad they were, no matter how bad they were.

Seeing Chen Fan's performance at this time, they also felt deep admiration in their hearts.

of course.

Although everyone was very excited, everyone in the live broadcast room laughed at what Jiang Wanli said about inviting archaeological experts: "Isn't that leader a joke? He also invited archaeological experts. I don't know that Mr. Chen Fan is one of the experts." Are you an expert?"

"That's right, they can even discover imperial tombs, which archeology expert is better than Mr. Chen Fan?"

Of course, this was to ridicule Jiang Wanli.

but.

The more this is the case, the more excited everyone is.

……

"I'll go down the water again and see if I can find anything else."

This time Chen Fan rested for half an hour.

no way.

I have been in the water more than a dozen times before. Although I have swimsuits and oxygen cylinders, my physical strength is also a huge exhaustion.

of course.

Chen Fan chose to go into the water again, and those professional launching teams naturally couldn't rest.

Whatever you say, you have to be with Chen Fan.

After half an hour.

Chen Fan and the entire launching team excitedly went ashore again.

and.

Along with Chen Fan, there was another brick that looked black.

Yes.

This is the brick that Chen Fan found during this trip into the water.

"If my guess is correct, the brick is a brick made more than 2000 years ago."

Adobe bricks have a long history.

More than 2000 years ago, our ancestors could already make it.

of course.

Their production process is not the same as today's.

But in general, many of them are similar to modern bricks.

"Of course, we have to wait for experts to identify the specifics."

Chen Fan put down the brick and sat down on the boat.

This time, he was really too tired.

……

[Heavy, the Dujiangyan ruins were discovered in Shu. 】

[Water conservancy projects more than 2000 years ago have surfaced today. 】

[Dujiangyan, let Shu become a land of abundance. 】

Originally, Chen Fan led everyone to discover Zheng Guoqu, which already shocked the country.

This time.

Chen Fan led a group of people to wait, and once again discovered the Dujiangyan Water Conservancy Project more than 2000 years ago, it was not just a simple shock.

"Ahhh, Teacher Chen Fan is too awesome."

"It used to be Zheng Guoqu, but now it's Dujiangyan... Nima, such a talent is simply rare in a thousand years."

"Damn, which university has a tour guide major, I want to apply for it too."

"It's useless to apply for the exam. Mr. Chen Fan's tour guide level may not be able to handle Mizuki Qingbei."

"I want to know now what the specific working principle of Dujiangyan is."

"I have to ask Teacher Chen Fan about this, but I heard that Teacher Chen Fan is sick."

"Oh no."

"Why not, didn't you see Teacher Chen Fan go into the water last time... Teacher Chen Fan soaked in the water for several hours that day."

"How about that, let's go see Teacher Chen Fan."

"Don't look any further. When you find out, the hospital where Teacher Chen Fan is located has already been surrounded."

……

There are stars in this world.

The former stars were those who sang, danced and filmed.

but now.

There is a kind of star who neither sings nor dances, let alone filming.

He is just a tour guide.

But such a tour guide has become an idol in the hearts of countless people.

Not to mention whether Teacher Chen Fan has made any contribution to Shu.

Just for his heart for the country and the people, every time they think of it, everyone is in awe.

This also lets.

When Chen Fan was admitted to the hospital because of a cold from entering the water.

These days, the entire hospital is surrounded by countless fans.

Among these fans.

Some of them were Chen Fan's diehards before.

There are also those who only saw Chen Fan's video before, but were not die-hard fans.

Also.

There are also many ordinary people in Shu, and some grandparents.

When they learned that Chen Fan was sick in the water, they dragged their families along for a while and wanted to come and see Chen Fan no matter what.

……

"I'll go, there are too many people here."

"Miss Nurse, I'd better go through the back door."

Seeing so many people outside, Chen Fan burst into tears.

He felt like he was doing nothing.

But with so many people outside, Chen Fan felt a little overwhelmed.

"Mr. Chen Fan, you don't want to meet with everyone?"

"Still gone."

"Teacher Chen Fan, they all want to meet you?"

"It's okay, I will start a live broadcast when I go back. There are too many people at the scene, I am flattered."

Chen Fan really couldn't stand it.

Whether it was the previous poems or others, Chen Fan only regarded himself as a porter.

As for Dujiangyan, it is also because of the history of the previous life, so Chen Fan is so sure.

He doesn't feel like he's done anything big.

He didn't do anything, but was thanked by so many people, Chen Fan felt a little sorry.

Fortunately, the hospital also understood Chen Fan's mood.

After Chen Fan was in good health, he arranged for Chen Fan to leave through the back door of the hospital.

……

But although leave.

But that night, Chen Fan fulfilled his promise and started the live broadcast immediately.

But what Chen Fan didn't expect was that.

As soon as the live broadcast started, thousands of planes and rockets flew towards Chen Fan.

"You guys, what's going on with you guys?"

"Stop swiping presents."

"Brothers, I am much richer than you, and I feel embarrassed if you give me gifts."

But the more Chen Fan said that, the more gifts he got.

"Brother Fan, don't talk about it, although we are poor, it is still okay to give you a small gift."

"Brother Fan, we are rich, and we just want to tip."

"Thousands of money are hard to buy, I am happy, Brother Fan, let's see the reward."

"Brother Fan, you are a unparalleled national soldier, I respect you..."

"..."

Seeing that everyone ignored him, Chen Fan had no choice but to turn off the tipping.

There is really nothing to do with them.

Although Chen Fan usually likes everyone to reward small gifts.

But Chen Fan also felt sorry for such a desperate reward.

"Okay, okay, turn off the tipping function."

Chen Fan smiled and said, "You guys are so crazy, it made me feel a little uncomfortable. After all, I didn't do anything."

"Brother Fan, you're being humble again. Seeing how you got into the water a few days ago, we were all worried to death."

"It's not that I went into the water alone, other people also went into the water, mainly because of my poor health. If it wasn't for my poor health, I could still go into the water for everyone to see."

"Brother Fan, if you say that again, we will all be ashamed to death."

"Okay, okay, let's not talk about this, let's talk about Dujiangyan. These days, I am treating patients in the hospital. I guess everyone must be very interested in Dujiangyan."

When launching into the water a few days ago, Chen Fan had already obtained the specific parameters of Dujiangyan.

After reading the working principle and specific data of Dujiangyan, Chen Fan really understood.

Why Dujiangyan can make Shu a land of abundance.

This kind of water conservancy project is simply the best in the world.

"It was launched a few days ago. Although the complete Dujiangyan water conservancy project no longer exists, when it was launched a few days ago, there were still some ruins under the water. Through these ruins, I can understand the working principle of Dujiangyan."

at this time.

Chen Fan's live broadcast room.

It's not just a crowd of fans paying attention.

The water conservancy department of Sichuan, and a group of people in charge of other regions.

There are also a group of water conservancy experts and professors who have also paid attention.

They had long wanted to chat with Chen Fan about the Dujiangyan issue.

But because Chen Fan was in the hospital, they couldn't bother him.

At this time, Chen Fan mentioned that everyone didn't blink their eyes, for fear of missing any word.

"The Minjiang River is the largest river that flows through the Chengshi Plain. This river is divided into four tributaries in the Chengshi Plain. However, the Minjiang River is different from other rivers. The upper reaches of the Minjiang River are very strong, and the dry area is very long. So for a long period of time, the Chengshi Plain was either flooded or drought. This made us feel very embarrassed. Guarding such a big river, we couldn’t make full use of its water conservancy. On the contrary, it caused huge damage to our survival from time to time. threaten."

side said.

Chen Fan took out the map of Minjiang River.

"More than 2000 years ago, Li Bing, the prefect of the Qin State, felt the harm caused by the Minjiang River to the people. Therefore, after he fully investigated the Minjiang River, he divided the Minjiang River into two at the junction of the Minjiang River and the Chengshi Plain. The larger part is called the Outer River, and the smaller part is called the Inner River. In this way, when the Minjiang River floods, the entire flood will not only flow to the Chengshi Plain."

Speaking of it.

Someone in the live broadcast room raised a question: "Brother Fan, dividing it into two alone cannot solve this problem."

"Yes."

Chen Fan nodded: "This is what I didn't make clear last time. Dividing it into two alone still can't withstand the flood, but what if we dig the inner river deeper and raise the outer river higher?"

"Dig the inner river deeper, and raise the outer river higher?"

Many people thought about it in their minds.

At the same time, Chen Fan also took out the drawing board and drew the structural diagram of Dujiangyan on the drawing board.

"You can see that the inland river is relatively small and deep. Then, during the dry season, because of its depth, about 6% to 7% of the water flow of the Minjiang River will be diverted to the inland river."

This is the most cutting-edge design of the Dujiangyan Water Conservancy Project.

This design is called a fish mouth.

Why is it called fish mouth?
In terms of image.

That is, when the Minjiang River came here, it was divided into two by a big fish.

Because the bifurcation is very similar to the mouth of a fish, it is also called the mouth of a fish.

This said, everyone's eyes lit up.

"Damn, with such a score, wouldn't it mean that during the dry season, our Chengshi Plain would not be short of water?"

"Nimma, this is a genius design."

If you don't explain it, everyone will naturally not understand.

But this explanation, even if you are not a water conservancy expert, is very excited at this time.

However, some fans asked again: "Brother Fan, it's mainly the rainy season, once the heavy rain comes, what should I do?"

"This is also easy to solve."

Chen Fan said: "Let's look at the outer river. What are the characteristics of the outer river? The outer river is characterized by a larger, wider and shallower river bed. During the dry season, the water will flow to the deeper side of the inner river. But once the rainy season comes, If the water level rises sharply, most of the river will flow to the wider outer river. In this way, even if the rainy season comes, it will not have much impact on the Chengshi Plain."

"I rely on..."

Such an explanation.

The entire live broadcast room went crazy in an instant.

"Ah ah ah ah ah ah ah."

"Deep inside and shallow outside, it's amazing."

"Whether the water conservancy department of Shu is here, design a construction plan quickly."

but.

Compared to the screams of the general public.

Some professionals asked again: "Mr. Chen Fan, I have to say that splitting the Minjiang River into two, with a deep inside and a shallow outside, can indeed play a lot of role. Especially in dry water areas, However, in the rainy season, it still cannot effectively block the river water. As the structure you just designed shows, even if the inland river is relatively small, but it is relatively deep, the water flow will also be very fast. Once it is urgent, the water volume will be large It will be very large, and it still poses a very big threat to the people in the city."

"Yes, this friend's opinion is very good."

Chen Fan nodded: "It's not enough to design such a fish mouth at the branch. As this friend said, when the rainy season comes, the current of the river is very fast. The plains have a huge impact. But what if we could slow the flow down?"

"Slow down?"

The expert who asked the question was a little confused: "How to slow down the water flow?"

The water is too fast to be stopped at all.

of course.

Not completely impossible.

You can also set dikes on it.

But the problem is.

With this setting, the water potential is too high, and the dam cannot bear it, so it can only release water.

Once released like this, the water potential is also very fast.

This urgent, the amount will be very large.

"It's easy too."

Chen Fan said: "We don't need to build a dam, we just need to make an opening like a bottle here, and then it will be fine."

"A bottle-like opening?"

See you do not understand.

Chen Fan began to draw on the drawing board again.

In front is the fish mouth.

Yuzui divides the Minjiang River into two.

Then came the bottle-like pattern drawn by Chen Fan.

This pattern is called the design of Baopingkou in Dujiangyan.

It means the mouth of the bottle.

finished painting.

Chen Fan said: "It is not a very reasonable solution to use only dikes for rolling water. But if it is designed as a bottle mouth, it will achieve unexpected effects. Let me give you a demonstration..."

Chen Fan said while taking out a bottle of mineral water.

"I'll open this bottle of water now and pour it down... Think about it, everyone, will our water flow very fast if it is poured down like this?"

You would think so if you didn't think about it.

Will do.

He must have flowed very fast.

But if you think about it carefully, or if you are good at observing, you will find that it is not.

Yes.

In the live broadcast room, everyone can see it.

Although Chen Fan had poured the bottle straight down at 90 degrees, the water in the bottle did not flow fast.

Not only was it not fast, but when the water in the bottle reached the mouth of the bottle, it was gurgling... It stopped here for a few times, and then slowly fell one by one.

"I seem to understand."

"I seem to understand."

"Isn't the principle of the bottle mouth drawn by Mr. Chen Fan the same as the current one?"

"That's right, that's how it is... There is no way to forcefully stop the rushing water. However, once an exit like a bottle mouth is set up under him, then even the rushing water will stop here, And make a circle to form a vortex... Then the whole river will slow down. Once the river slows down, then the water flowing into the Chengshi Plain will be much less."

"That's not all. If it's done like this, not only can the river stop slowly at the mouth of the bottle, but it can also throw the sand to the bank through the vortex. In this way, the water flowing down the river will become Much cleaner."

"Sister... this, this, this..."

Yes.

If the fish mouth in Dujiangyan is a genius design.

Then.

The treasure bottle mouth under the fish mouth is simply a masterpiece handed down from generation to generation.

When this treasure bottle came out, the entire live broadcast room was completely boiling.

Especially for those netizens who specialize in water conservancy.

After getting Chen Fan's explanation, they all jumped out excitedly.

"Everyone, don't get excited, I haven't finished talking yet."

In fact.

Dujiangyan is not just that simple.

Then, Chen Fan said: "Yuzui and Baopingkou, they can basically stop more than 90% of the flood. But this is not enough. Sometimes the water potential of the Minjiang River is really unimaginable. Once the rainy season surges, it is very dangerous. Maybe neither the fish mouth nor the treasure bottle mouth can stop it. Therefore, we should also adopt a third design scheme near the treasure bottle mouth.”

"What plan?"

"This design is called Feishayan."

"What is Feishayan?"

"It's a building like a dam. Once the Minjiang River has a rainy season that doesn't happen in a hundred years, the water level here at Baopingkou will also be mostly raised. But at this time, if we build a location near Baopingkou A lower dam. Then, once the water level at Baopingkou rises, the river will flow into the outer river through Feishayan, and it will no longer have any impact on the Chengshi Plain..."

fish mouth.

Aquarius mouth.

Feishayan.

This is the design plan for the entire Dujiangyan.

When explained here.

The number of people in the entire live broadcast room has exceeded 5000 million.

And in this moment.

The water conservancy departments of Shu, including the water conservancy departments in various regions of China, were all shocked at this moment.
