Into Unscientific

Jiang Chenggu's words can be regarded as a statement in the capacity of the general office.

That is to say, the "beheading" plan proposed by Zhang Ziang was initially accepted.

Of course.

It's just preliminary.

After all, for such an important project, it is impossible for someone to say everything—whether it is Jiang Chenggu or Zhang Ziang, an academician of the Academy of Engineering.

to put it bluntly

Although the domestic academicians of the Academy of Engineering are precious, there are nearly a thousand of them.

If academicians of the Academy of Sciences are counted, the number is even close to 2,000.

But what about Yongling?

But there is only one.

Although these two concepts are actually not comparable, they can be used as a reference in nature.

Therefore, in terms of the excavation of Yongling, it must go through a higher level of discussion.

What Jiang Chenggu and Zhang Ziang can do is to write down their ideas as detailed as possible, so as to convince the bosses above.

Zhang Ziang obviously understood this very well.

Therefore, after the detection team finished the detection, he immediately led the experts of the excavation team to conduct a program demonstration.

Finally on the morning of the third day.

Zhang Ziang handed over a complete plan to Jiang Chenggu, who forwarded it to a higher level.

Then another day passed.

Jiang Chenggu sent a high-level reply:

In principle, I agree with Zhang Ziang's team's excavation plan, and ask the committee to start excavation preparations immediately. During the construction process, China Construction Seventh Bureau will provide equipment assistance.

The start time of the mausoleum is in.

two weeks later.

be honest.

This time is not too outrageous.

After all, the gravity gradiometer has clearly detected the structure of the tomb, and the target range of the first phase of the project is also very small:

Only the apse was cut, and the other eight side halls remained as they were.

In other words.

During the whole process, the only cultural relics that really need to be considered for protection are the four coffins in the apse, plus the issue of airtightness between the apse and the side hall.

99.98% of the cultural relics in the Yongling Underground Palace (this number is not an exaggeration) will not be unearthed during this cutting process.

Therefore, in terms of the difficulty of preserving cultural relics, it is undoubtedly several steps lower than the normal excavation of imperial tombs.

The official naming of this cut and excavation is relatively traditional, called [Yongling Underground Palace Phase 1 Excavation Project], which has no special features.

But Xu Yun and Lu Chaoyang privately gave it a code name:

[Homage to Louis XVI].

two weeks later.

March 1, 2023.

It was early in the morning.

Xu Yun and others gathered again in the Ming Tombs area.

It was still the same people as two weeks ago, but the equipment around them was completely different from before.

For example, outside the treasure city of Yongling, there are a lot of large-scale equipment and clearly divided preparation areas.

"Director Jiang, Academician Pan, these are the construction sites we have prepared."

Outside Baocheng.

A group led by Zhang Ziang was walking around the construction site wearing hard hats.

Zhang Ziang first led the crowd to several huge excavators, and patted the body of one of them with the palm of his hand wearing labor protection gloves:

"These excavators are the main equipment for our excavation this time. They are all Sany SY205C, or Sany 205 for short."

"Its length, width and height are 9680 x 2980 x 3440 mm, its tonnage is 21.5 tons, and its bucket capacity is 1.1 cubic meters."

"Before digging down to 27 meters underground, it was the protagonist of this phase of the project."

Xu Yun raised his head and glanced at this huge monster. While feeling the huge size in his heart, he also had a question:

"Academician Zhang, shall we rely on these excavators to dig the pit this time?"

Zhang Ziang glanced at him, smiled and asked:

"Why, Dr. Xu, do you think they are not efficient enough?"

"No, no, I'm not talking about efficiency."

Xu Yun quickly shook his head, gestured a height in the air with his hands, and said:

"This Sany 20205 is right. Its work efficiency is definitely not low, but its mechanical arm doesn't look long. I guess it can dig five meters and six meters, right?"

"But the depth of the apse is 27 meters in the surface layer alone. With the length of the mechanical arm of 205, how can we dig to the position of the apse?"

I heard this.

Lu Chaoyang, Huang Yuting and even Academician Pan beside Xu Yun all showed curious eyes.

What Xu Yun said happened to be their question.

Then Zhang Ziang glanced at Xu Yun, did not give an answer directly, but asked Xu Yun:

"Dr. Xu, since you think the mechanical arm of the excavator is not enough, in your opinion, what kind of equipment should be used for this kind of project?"

Xu Yun replied subconsciously:

"of course"

As a result, I just finished saying the three words [of course].

He got stuck abruptly.

drilling?

Obviously impossible.

Although the depth of the borehole is deep, the area is small, and it is mainly used for piling or sampling.

Shield machine?

This is not right either.

Although the usage scenario of this thing is underground, it is mainly used for horizontal excavation, such as tunnels or subway passages.

Want explosives?

it's even more impossible

After thinking about it like this, Xu Yun just noticed a problem that he had ignored:

There are many underground buildings in real life. From the subway platform to the underground shopping mall, the depth is basically more than ten or even twenty or thirty meters deep.

So take care.

If there is a special equipment for excavating underground facilities, it is impossible for him not to have seen it.

But no matter what he thought at the moment, he couldn't think of a reasonable answer.

Could it be

Really an excavator?

Seeing Xu Yun's bewildered expression, Zhang Ziang couldn't help but smiled and patted him on the shoulder:

"Little Dr. Xu, as the saying goes, there is a priority in learning, and there is a specialization in art."

"I may not be as good as you in professional academics, but in terms of architectural knowledge, your knowledge may be limited."

"Let me tell you the answer. The excavation equipment used in those underground projects are all this type of excavator!"

finished speaking,

Zhang Ziang paused, organized his words, and continued:

"This excavation method is called the open-cut method, and it is common in projects with a depth of no more than 40 meters. There are many types of open-cut methods. This time we are using open-cut without slope."

Then Zhang Ziang swept around and quickly locked on to a target.

I saw him pointing at several large drilling equipment not far from everyone, and continued to explain:

"No, have you seen those green pile drivers?"

"When construction starts, they'll drill holes around the perimeter of the piece of land we're going to dig and then fence off the area with cast-in-situ piles - the main purpose of which is to increase resistance to soil pressure."

"A similar link is that Shisui is not the Uchiha Shisui, it means preventing water from seeping through."

"After finishing these, you can start digging."

"As for Dr. Xu, what you said is that the length of the mechanical arm is not enough. Our solution is to excavate in layers, that is, the excavator will enter the next layer to continue digging every few meters."

"This process requires the erection of concrete supports or steel supports - there is a specific formula for calculating the load capacity, and the relevant technologies are already very mature."

"At a depth of 30 meters, as long as our initial excavation area is large enough, and about four floors are erected, we can dig to the upper floor of the apse."

Students who have been brothers in civil engineering in this life should know it.

The key points of digging pits, to put it bluntly, are actually two words:

Envelope construction and waterproofing.

After all, everything is under pressure, and soil certainly has it.

Simply put.

If you dig out the soil in the middle of a field, the soil next to it will squeeze into the middle.

If too much soil is dug, the squeezing force is too large, exceeding the friction between the soil and the soil.

Then the position of the soil will be seriously displaced, causing the foundation pit to collapse, and eventually cause engineering accidents.

The enclosure structure mainly plays the role of balancing the earth pressure and preventing the accidental collapse of the foundation pit.

However, the enclosure structure is simple to say, but in fact there are many types.

For example, there are bored piles, ground-to-wall, steel supports, concrete supports, etc.

Nowadays, all kinds of underground facilities are commonly used, mainly in the form of bored pile + concrete support + steel support.

This method starts with piling with a piling machine, and the soil removed from the piling will be thrown into a pre-made muck pool, and then consigned out at night.

After the piles are driven, the engineering team will hang a steel cage into the hole—that is, a huge hollow steel column that is long, dark, thick, and hard. After the steel column is stuffed into the hole, it will start to go into the hole Pouring sticky concrete.

After these pillars are finished, the excavation can begin.

When the excavator arm is not long enough, it can be excavated in a layered mode, which is equivalent to building a small building upside down. (Thanks to the professional knowledge provided by Mr. Ya, the author of "I Came After I Became the Golden Finger")

Then the group continued on, chatting as they walked.

Zhang Ziang also introduced the water-stop curtain, spoil pool, welding machine shed and other facilities and areas to Xu Yun and others, so that everyone had a general understanding of the construction situation.

After about ten minutes.

Everyone stopped in front of another huge device.

This is a giant transport vehicle with a body length of about 20 meters. Its body is gray and white, and it looks quite domineering.

However, it is not the body of the transport vehicle that really attracts the attention of passers-by, but a green metal folding bracket placed on its lifting platform that is longer than the body.

Even for a medium-sized excavator like the SY205C, in front of this giant transport vehicle, it is an ordinary fat man who meets his ears on the road—the little chubby sees the big chubby.

If you meet an interstellar player with poor eyesight, Bao Buqi will still regard this car as a Dongfeng transport vehicle.

Face off against this real Big Mac.

Even a well-informed boss like Academician Pan couldn't help but have a flash of shock in his eyes:

"Academician Zhang, this is."

The astonishment of Academician Pan and others seemed to be very beneficial to Zhang Ziang. He also reached out and patted the outer shell of the vehicle, and said proudly:

"Everyone, didn't I say something before—before the apse was excavated, the protagonist of the scene was SY205C."

"And the car in front of everyone is the protagonist of our second half."

"It is the ZAT18000H crane produced by Zoomlion, and it is also one of the most advanced cranes not only in China, but also in the world."

Everyone couldn't help being stunned again when they heard the words:

"crane?"

Then Weng Tong looked suspiciously at Zhang Ziang, and asked this old acquaintance:

"Old Zhang, you call this a crane?"

"Let me tell you, the group of people around you can read a lot today. They are either academicians or professors or 985 doctors. Don't lie to us."

"The cranes in my impression are all crawler-type large-scale equipment, or the gantry cranes that look like a small bench magnified 10,000 times. When did the cranes have such a style?"

Zhang Ziang gave him a disgusted look, then took out his mobile phone from his pocket and handed it to Weng Tong:

"I knew you were going to ask this kind of question. Here, Baidu has searched for you in advance. Let's see."

Weng Tong:

"."

Everyone:

"."

Was this predicted?

Then Weng Tong took out his phone and looked at it for a few moments, then raised his eyebrows in surprise:

"Hey, is this really a crane?"

Zhang Ziang snorted coldly, looking a little arrogant:

"Of course, you don't even think about it, can I lie to you at such a critical moment?"

"This crane is specially designed for land wind turbines, and the working environment is often in the wild, so it has a strong off-road character in appearance and performance."

"Isn't the picture of SpaceX's starship erected very popular, and the huge crane next to it is also famous - that is the Liebherr LR11350 crawler crane of the German Liebherr Group , with a maximum rated lifting capacity of 1,350 tons, it is a younger brother in front of our crane."

"The hoisting height of our ZAT18000H can reach 140 meters, and the hoisting weight can reach 1,800 tons, which is currently the first in the world."

As soon as Zhang Ziang said those words.

The eyes of everyone looking at this ZAT18000H suddenly changed.

Damn.

1800 tons

To know.

A cubic meter of reinforced concrete has a density of 2.5 tons.

The average floor thickness of a residential building is 0.2 meters, so the weight per square meter of the floor is about 0.5 tons.

Then calculate the weight of the wall and the equipment in the room.

A set of commercial houses with the same area as the apse, the total weight will fluctuate between 5-10 tons - the one full of goods is another story.

Although there are still coffins and stone platforms in the apse where Jiajing’s coffin is located, no matter how heavy the entire apse is, it can never exceed 20 tons.

in this case.

Zhang Ziang took out the 1800-ton ZAT18000H

This moment.

There is only one sentence floating in everyone's mind:

Kill the chicken with a bull knife.

This tmd is no longer stable and can be described, okay?

Think here.

Huang Yuting couldn't help giving Zhang Ziang a thumbs up, and said in admiration:

"Academician Zhang, you are too steady. It seems that we juniors still need to learn more."

"If I were to do the plan, I estimate that using a 300-ton crane would be considered exceeding the standard."

Zhang Ziang glanced at her, and when facing this unfamiliar girl, he was not as casual as he was with Weng Tong:

"Uh, Professor Huang, to be honest, I didn't even think about using this machine at first."

"The earliest we planned to use was another smaller crane with a lifting capacity of only 500 tons, but"

Zhang Ziang didn't finish.

Huang Yuting answered the words as if she had realized something:

"But out of a sense of mission to excavate Yongling, that's why you temporarily changed to the safer ZAT18000H?"

Zhang Ziang glanced at her, then quickly shook his head:

"No, Manager Huang from Zoomlion found me and said that if ZAT18000H can show up in this excavation live broadcast, they will provide a batch of advanced equipment for free for another excavation project in my hand."

Huang Yuting:

".?"

all in all.

After introducing the ZAT18000H crane.

Zhang Ziang's circle round was almost officially over.

So far, everyone has a rough idea of ​​the planning of the whole project.

Then everyone returned to the temporary headquarters and made final preparations.

After more than twenty minutes.

A message from the on-site assistant:

The units are officially in place.

Jiang Chenggu walked to the temporary workbench, looked around at the construction representatives and media representatives around him, and said:

"Dear guests, dear colleagues, workers, hello everyone!"

"I am Jiang Chenggu from the GWY General Office. Today we are very honored to welcome the groundbreaking ceremony of the first phase of Yongling, an important project in the Ming Tombs excavated by the state."

"As one of the representatives of ancient Chinese royal tomb groups, the Ming Tombs have a long history of completion. They have witnessed the change of dynasties and carried profound historical and cultural heritage."

"The Yongling Tomb is an extremely important tomb among the Ming Tombs."

It turns out.

Even Jiang Chenggu, a seemingly capable official, was also very inefficient in his speech and couldn't break away from the cliché.

It took him more than ten minutes before and after to finish speaking a bunch of nutritious but essential content.

After the speech, the

Lottery link.

well known.

It is different from the so-called foundation-laying "custom" of a group of people in the foundation-laying project shoveling sand into the stone-laying marble bunker.

The "lottery" of an archaeological excavation project is exactly the opposite in terms of process:

It is to let a group of people wield hoes to dig out the pre-buried things from a shallow soil layer.

This custom is the same as the sacrifice of pig heads at the start of the movie. Strictly speaking, it is not a feudal superstition-like these days, there are still photos of electronic pig heads, and it is more for fun.

The same is true for the Yongling excavation this time.

So soon.

Jiang Chenggu, Academician Pan, Zhang Ziang, Weng Tong and Tong Huaijun walked to a soil layer with hoes on their shoulders.

Then they waved their hoes a few times, successfully dug out a white silk of the same style as Chongzhen, and selected a lucky viewer on the live broadcast platform to give it away.

Finish these.

The excavation project of Yongling officially started.

Boom boom boom——

The roar of equipment soon sounded on the construction site, and the air gradually filled with the smell of sand and gravel.

at the same time.

There were also a lot of melon-eating viewers in the major live broadcast rooms.

How strong the ability of Chinese netizens to eat melons is, this can be seen from the fact that tens of millions of people on the Internet watched the live broadcast of the construction of Huoshenshan Hospital.

Of course.

Compared with the previous major events, the number of live broadcasts of Yongling excavation is still much smaller.

From the very beginning.

The real number of people watching the live broadcast on the entire network is about 800,000, and the number scattered across various platforms is even smaller.

At the same time, this type of live broadcast will not encounter any hacker attacks, basically it is considered a hot news.

Therefore, Xu Yun took out his mobile phone in his free time and checked the trending searches on Weibo.

as expected. # Yongling Construction Live Stream # This trending search has rushed to the second place, second only to the first and explosive national examination results.

When the enthusiasm for the national exam dissipates tomorrow, the topic may still have a chance to rush to the top.

Then Xu Yun clicked on the topic square again.

as expected.

At this time, a lot of criticisms can still be seen in the square, basically all of which refer to the original Dingling tragedy.

It's not difficult to see from the text that some people are indeed worried, and some people use Dingling to criticize certain people.

Xu Yun didn't pay too much attention to this, and he had seen similar remarks in the past few days.

After scanning these discussions, he continued to read other news.

But watch and watch.

He suddenly froze.

Only at this moment.

At the 17th most searched position on Weibo, there is a topic: # Xu Yun was killed this year # Xu Yun:

"."

What the hell is this hot search tmd?

Then he clicked on the topic and found that there was a personal user's dynamics hanging on the square:

【Little Tong Tong who loves Zhang Ying】:

[Convex (ヒペプ), what's going on this year? From the beginning of the year to now, there have been so many major events, except for Mikami Yuya's retirement, all of them are related to Xu Yun. Did I commit Xu Yun's crime this year or what happened? 】

This moment.

The number of comments on this Weibo has exceeded 6,000.

For a personal account that is not a big V and only has more than 2,000 fans, this is undoubtedly a data that can be called a "big explosion".

It's just that Xu Yun feels a little uncomfortable looking at this content

What is the murderer Xu Yun?

Is it a thing to co-operate with me?

Then Xu Yun hesitated for a moment, and with a very subtle psychology, reached out and clicked on the comment section of this Weibo.

Among them, the number one hot comment has no text content, but an emoji package.

As a result, the moment Xu Yun saw this emoji, he couldn't hold back immediately:

"Your uncle!"

I saw that the content of this emoticon package is neither a panda head nor a star, it is impressively

Xu Yun himself!

In this picture, Xu Yun shrugged slightly with his neck shrunk, the corners of his mouth drooping downwards, inexplicably in need of a beating.

At the same time, the person who took the screenshot also added the words [Jijiujiujiu] in the picture, which seemed to be ridiculed to the best of its ability, and it was inexplicably worthy of a beating.

The moment he saw this picture, Xu Yun's first reaction was the P picture.

But soon he remembered one thing:

At the previous dark matter press conference, when he told Atsuto Suzuki that the atomic bomb would explode twice, it seemed that

Did you really do this?

At present, the number of likes of this comment has reached 12,000, and there are more than 300 reply floors.

The content in it is basically comments such as [good picture] [accepted] [Bangzi National Flag. JPG], and the level of harmony is comparable to that of the host and good people under the link of the pornographic film.

Ding dong——

Just as Xu Yun was scrolling through Weibo.

He suddenly received a message on WeChat.

The pop-up window of the message happened to be on the status bar of the phone, so Xu Yun clicked on it without much hesitation.

The sender of this message is Chen Shanshan, the mother of cockroaches, and the content of the message is astonishingly.

Xu Yun just saw this emoji package.

Xu Yun: "."

Your uncle (╯‵ ′)╯︵┻━┻!!!

Although the balance of the account differs by hundreds of thousands of miles, at this time Xu Yun inexplicably understood the tearing onion that became popular because of a hot dog photo.

Then he stuffed the phone back into his pocket, out of sight.

Then he took a deep breath, stood up from his seat, came to Zhang Ziang on the podium, and asked:

"Academician Zhang, according to the current situation, how long will it take for us to dig the location of the apse?"

Zhang Ziang looked up at the construction site in the distance, and said after deliberation:

"Drilling, placing steel cages, and pouring concrete are three essential processes. From drilling to concrete setting. This refers to the final setting. It takes at least two days."

"In addition, we need at least four layers of steel support, that is, four reinforcements."

"Including the total time for pressurization and stabilization, it will take several days. In the whole process, it is the excavator that takes the shortest time to dig the soil."

"All together. If it is fast, it will take twelve or three days, if it is slow, it will be about three weeks, and you should be able to dig to the top of the apse." (I calculated this time by checking the data myself. Does anyone in the industry give me some advice? Unreasonable? Unreasonable, I will change it)

"Of course, if we work in three shifts and work hard, it can be done in a short period of time-but this is the efficiency of combat readiness regardless of cost. At least our current plan does not consider this possibility."

"After all, Jiajing won't be resurrected after a few days of delay. After the founding of the People's Republic, he is not allowed to become a master."

Only then did Xu Yun understand.

Based on the excavation of the area where the apse is located in two weeks, it should not take too long for the apse and the copper hall to be unearthed.

That is to say

In a few days.

"Yongle Dadian" can truly come to life.

The newly adjusted biological clock has not completely turned around, and I feel a little uncomfortable, so I will type these first, and I will make up for it tomorrow with a few hundred words and nine thousand
