"It's late, let's go into the water today."

"Teacher Chen Fan is here."

"I guess there's still not much hope."

The crowd sighed.

But think about it too.

The water conservancy project more than 2,000 years ago is really difficult to find.

You said on land, maybe there was still a possibility.

But in the water...... Not to mention the change of ground type, it is the erosion of the Minjiang River for thousands of years, and it may also be washed away.

It's just that.

Just when everyone thought that there might be nothing to gain today.

Chen Fan, who had just surfaced, shouted excitedly: "Found it, I found the Dujiangyan site." ”

The voice came out.

The whole live broadcast room roared.

"Found it?"

"Damn, did I really find it?"

"Oh my god......"

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

But I heard Chen Fan say before that it was precisely because of Dujiangyan that Shu became the country of abundance.

Want.

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

At this time, if we can really reproduce the style of Dujiangyan back then, not to mention anything else, I am afraid that the situation of a major flood in the past ten years can be solved.

"Teacher Chen Fan, have you found it?"

"Hmm."

Standing on the boat, Chen Fan said: "I went into the water just now and found that there were several protrusions...... I think this is Dujiangyan 2,000 years ago. ”

"By the way, I brought some dirt with me."

"Great."

Jiang Wanli was also excited at this time, and said, "Teacher Chen Fan, then you can rest first, and we will send someone 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 moment, I want to find out what's going on under the water. In addition, I would like to ask the relevant experts to confirm ......"

"Let's take a break."

"Nope."

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

"This ......"

Although it was almost dark at this point.

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

Saying that, Jiang Wanli said loudly again: "Why don't you hurry up and invite archaeological experts to enter the site." ”

Such a scene also made everyone in the live broadcast room fight one after another.

"I went, and this scene, I instantly ignited."

"Me too, once Dujiangyan is really discovered, I am afraid it will be a great miracle in China's water conservancy projects for thousands of years."

"So burning, so excited, Mr. Chen Fan, you are our role model."

Stars twinkled in everyone's eyes.

No matter how rational he was before, he didn't chase stars, and he wasn't a good person.

At this time, seeing Chen Fan's performance like this, they also had deep admiration from their hearts.

Of course.

Although everyone was excited in their hearts, everyone in the live broadcast room laughed at what archaeological experts Jiang Wanli said: "Is that leader funny, and also invited archaeological experts, don't you know that Mr. Chen Fan is an expert among experts?" ”

"That is, people can even find the imperial tomb, which archaeological expert has Teacher Chen Fan?"

Of course, this is to ridicule Jiang Wanli.

But.

The more this happened, the more excited the hearts of the people became.

……

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

This time, Chen Fan rested for half an hour.

No way.

I had been in the water more than a dozen times before, and although I had a swimsuit and an oxygen tank, my physical strength was also a huge drain.

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.

Half an hour later.

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

Moreover.

Coming up with Chen Fan, there was also a brick that looked black and mushy.

Yes.

This is the brick that Chen Fan found in the water this time.

"If my guess is correct, this brick is a brick made more than 2,000 years ago."

Adobes have a long history.

More than 2,000 years ago, our ancestors were able to make it.

Of course.

Their craftsmanship is different from what it is now.

But the general appearance, there are many similar to modern bricks.

"Of course, the specifics have to wait for experts to re-evaluate."

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

This time, he was really too tired and tired.

……

[Heavy, the site of Dujiangyan was discovered in Shudi. 】

[More than 2,000 years ago, the water conservancy project has surfaced today. 】

[Dujiangyan, let Shu become the country of abundance. 】

Originally, Chen Fan led everyone to discover Zheng Guoqu, which had 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 2,000 years ago, which was not just shocked.

"Ahhh

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

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

"It's useless to apply for the exam, Mr. Chen Fan's tour guide level, Shuimu Qingbei may not be able to get it."

"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."

"Ah...... No way. ”

"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. ”

"Then how can it be done, let's go see Teacher Chen Fan."

"Don't go and see, when you find out, the hospital where Teacher Chen Fan is located has already been surrounded."

……

There are stars in this world.

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

But now.

There is a kind of star who neither sings, nor dances, nor films.

He's just a tour guide.

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

Not to mention whether Mr. Chen Fan has made any contribution to Shudi.

rushed to his heart of serving the country and the people, whenever he thought of it, everyone was in awe.

This also lets.

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

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

Among these fans.

Some of them are the irons of Chen Fan before.

There are also those who have only swiped Chen Fan's videos before, but they are not die-hard fans.

Other than that.

There are also many ordinary people in Shudi, as well as some uncles and aunts.

When they learned that Chen Fan was sick in the water, they dragged their families for a while, saying that they wanted to come and see Chen Fan.

……

"I'll go, there's too many people."

"Little sister nurse, I'd better go through the back door."

Looking at so many people outside, Chen Fan burst into tears.

He didn't feel like he was doing anything.

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

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

"It's still gone."

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

"It's okay, I'll start a live stream when I get back. There were so many people on the scene, I was flattered. ”

Chen Fan is really a little unbearable.

Whether it is the previous poems or others, Chen Fan only thinks of 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 didn't feel like he had done anything big.

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

Fortunately, the hospital also understands Chen Fan's feelings.

After Chen Fan's body was normal, he arranged for Chen Fan to leave through the back door of the hospital.

……

But leave though.

But Chen Fan fulfilled his promise that night and started the live broadcast as soon as possible.

But what Chen Fan didn't expect was.

This live broadcast, thousands of planes and rockets came towards Chen Fan's side.

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

"Stop brushing gifts."

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

But the more Chen Fan said this, the more fierce the gift became.

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

"Brother Fan, we just have money, we just want to reward."

"I'm happy to buy a thousand dollars, Brother Fan, look at the reward."

"Brother Fan, you are a peerless countryman, respect your ......"

“……”

Seeing that everyone didn't pay attention to him, Chen Fan had no choice but to turn off the reward.

There's really nothing you can do about them.

Although Chen Fan usually likes everyone to give small gifts.

But such a lifeless reward, Chen Fan didn't want to go.

"Alright, alright, turn off the tipping function."

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

"Brother Fan, be humble again, look at your deathless entry into the water a few days ago, we are all worried about death."

"It's not me who went into the water alone, other people also went into the water, the main reason is that I am in poor health, if it weren't for my poor health, I would still be able to go into the water to show everyone."

"Brother Fan, if you say this again, we will all die of shame."

"Okay, okay, don't talk about this, let's talk about Dujiangyan. These days in the hospital, I guess everyone must be very interested in Dujiangyan. ”

When he went 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 country of abundance.

Such a water conservancy project is simply the best in the world.

"A few days ago, although the complete Dujiangyan water conservancy project no longer exists, but when it was launched a few days ago, some ruins were still retained under the water. Through these sites, I also understand the working principle of Dujiangyan. ”

At this time.

Chen Fan's live broadcast room.

It's not just a bunch of fans who are paying attention.

Shudi water conservancy department, and a group of responsible persons from other regions.

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

They had long wanted to talk to Chen Fan about the problem of Dujiangyan.

However, because Chen Fan was in the hospital, they were not easy to disturb.

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

"The Min River is the largest river flowing through the Chengshi Plain, and this river is divided into four tributaries in the Chengshi Plain. However, there are some differences between the Min River and other rivers. The water potential in the upper reaches of the Min River is very large, and the dry area is very long. So for a long time, the Chengshi Plain was either a flood or a drought. This makes us look very embarrassed, guarding such a big river, we can't give full play to its water benefits, but from time to time it poses a huge threat to our survival. ”

While saying.

Chen Fan took out a map of the Minjiang River.

"More than 2,000 years ago, the Qin State guarded Li Bing, and he felt the harm caused by the Minjiang River to the people. So, 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 big one is called the outer river, and the small one is called the inland river. In this way, when the Minjiang flood breaks out, then the entire flood will not only flow to the Chengshi Plain. ”

Speaking of which.

Someone in the live broadcast room raised a question: "Brother Fan, this division alone can't solve such a problem." ”

"Yes."

Chen Fan nodded: "This is also what I didn't make clear last time." Splitting in two alone will not be able to withstand the intrusion of floods, but what if we dig deeper into the inner river and raise the outer river a little higher? ”

"The inner river is deeper, and the outer river is higher?"

Many people thought about it in their heads.

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

"You see, the inland river is relatively small and deep. Then, during the dry season, because of his deep reason, about 6 to 7 percent of the water flow of the Min River will be distributed to the inland river. ”

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

This design is called a fish mouth.

Why is it called a fish mouth?

Figuratively speaking.

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

The bifurcation is called a fish mouth because it resembles a fish's mouth.

This said, everyone's eyes lit up.

"Damn, with such a point, wouldn't it be during the dry season, and there would be no shortage of water in our Chengshi Plain?"

"Nima, this is a genius design."

If you don't explain, you won't know.

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

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

"That's easy to solve."

Chen Fan said: "Let's look at the outer river, what are the characteristics of the outer river? The characteristics of the outer river are that the riverbed is relatively large, relatively wide, and relatively shallow. During the dry season, the water flows to the deeper side of the river. But when the rainy season arrives and the water level soars, most of the water flows 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 ......"

This is how it is explained.

The entire live broadcast room went crazy in an instant.

"Ah......hh Ahhh ”

"It's deep inside and shallow outside, it's amazing."

"The Shudi water conservancy department is not here, so hurry up to design a construction plan."

But.

Relative to the screams of the general crowd.

Some professionals asked: "Teacher Chen Fan, I have to say that dividing the Minjiang River into two can indeed play a lot of roles in the way of inner depth and outer shallowness." Especially in dry areas, but if it is rainy, he is still not able to effectively block the river. As you have just designed, even though the river is relatively small, it is relatively deep and the current can be very fast. In case of emergency, the amount of water will be very large, which is still a very big threat to the people in the urban area. ”

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

Chen Fan nodded: "It's not enough to design such a fish mouth at the bifurcation. As this friend said, when the rainy season comes, the river flow is very fast, and this kind of rushing down will still have a huge impact on the Shu Plain. But what if we could slow the flow down? ”

"Slow down?"

The expert who asked the question was a little puzzled: "How do you slow down the flow of water?" ”

The water is too fast to stop.

Of course.

It's not completely impossible.

You can also set up a dam on it.

But here's the thing.

If this is set, the water will be too strong and the dam will not be able to withstand it, so it will have to release water.

In this way, the water is also very urgent.

This urgency will also 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's good to go." ”

"Bottle-like openings?"

See that everyone does not understand.

Chen Fan drew on the drawing board again.

In front is the mouth of the fish.

The fish mouth divides the Min River in two.

Then there is the bottle-like pattern painted by Chen Fan.

This pattern is called the design of the treasure bottle mouth in Dujiangyan.

It means the mouth of the bottle.

Finished.

Chen Fan said: "If you only use dikes, it is not a very reasonable solution. But if it is designed as a bottle mouth, it will achieve unexpected results. I'll show you ......."

Chen Fan said as he took out a bottle of mineral water.

"I'm going to open this bottle of water now and pour it down...... Think about it, if we fall like this, will our water flow very fast? ”

If you don't think about it, you'd think.

Yes.

He must have flowed very fast.

But if you think about it, or if you are observant, 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 quickly.

Not only is it not happy, but the water in the bottle is gurgling when it reaches the mouth of the bottle...... It stopped here a few times, and then slowly fell one by one.

"I seem to get it."

"I seem to get it, too."

"Isn't the principle of the bottle mouth painted by Mr. Chen Fan like the current one?"

"yes, that's it...... If the water is too fast, there is no way to stop it. However, once an outlet was set up under him like the mouth of a bottle. Then, even the most rapid river will stop here and form a whirlpool in circles...... Then the whole river slowed down. Once the river slows down, there will be much less water flowing into the Chengshi Plain. ”

"And that's not all. If this is done, the mouth of the bottle will not only allow the river to stop slowly, but also throw the sediment to the shore by whirlpooling. In this way, the water flowing into the lower river becomes much cleaner. ”

"Sister...... This and this ......"

Yes.

If the fish mouth of Dujiangyan is a genius design.

So.

The mouth of the treasure bottle under the fish's mouth is simply a masterpiece.

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

Especially for those netizens who are professional in water conservancy.

After getting Chen Fan's explanation, they were so excited that they were about to jump out.

"Everyone, don't get excited, I'm not done yet."

In fact.

Dujiangyan is more than that.

Then, Chen Fan said: "The mouth of the fish and the mouth of the treasure bottle, he can basically stop more than 90% of the flood. But this is not enough, the water potential of the Minjiang River is sometimes really unimaginable. Once the rainy season soars, it is very likely that the fish mouth and the treasure bottle mouth will not be able to stop it. So, in this, we should also take a third design scheme near the mouth of the bottle. ”

"What's the plan?"

"This design is called a flying sand weir."

"What is a flying sand weir?"

"It's a building like a dam. Once the Minjiang River comes to a rainy season that has not been seen in a century, the water level here at the mouth of the treasure bottle will also be mostly raised. But at this time, if we build a low-level embankment near the mouth of the treasure bottle. Then, once the water level of the mouth of the treasure bottle rises, then the river water will flow together with the outer river through the flying sand weir, and it will no longer have any impact on the Chengshi Plain......"

Fish mouth.

Treasure bottle mouth.

Flying sand weir.

This is the design scheme of the entire Dujiangyan.

When explained here.

The number of people in the entire live broadcast room has exceeded 50 million.

And at this moment.

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