Chapter 494 Sure enough, Xu Yun was killed this year (please vote for the big chapter!!!)
Jiang Chenggu's words were regarded as a statement in his capacity as the general office.
That is to say, the "beheading" plan proposed by Zhang Ziang was initially accepted.
Of course.
It's just a preliminary step.
After all, such an important project cannot be the sole responsibility of one person - whether it is Jiang Chenggu or Zhang Ziang, an academician of the Academy of Engineering.
To put it bluntly
Although domestic academicians of the Academy of Engineering are rare, their number is close to a thousand.
If you include academicians of the Academy of Sciences, the number is even close to 2,000.
But what about Yongling?
But there is only one.
Although these two concepts are not actually comparable, they can serve as some reference in nature.
Therefore, the excavation of Yongling Tomb must be discussed at a higher level.
What Jiang Chenggu and Zhang Ziang can do is write down their thoughts in as much detail as possible to convince the bosses above.
Zhang Ziang obviously understood this very well.
Therefore, after the detection team completed the detection, he immediately led the experts from the excavation team to conduct a plan demonstration.
Finally on the morning of the third day.
Zhang Ziang handed a complete plan into the hands of Jiang Chenggu, who forwarded it to higher-ups.
Then another day passed.
Jiang Chenggu received a reply from a senior executive:
In principle, we agree with the excavation plan of Zhang Ziang’s team and request the committee to immediately start excavation preparations. During the construction process, China Construction Seventh Engineering Bureau will provide equipment assistance.
The construction of the mausoleum will start at.
Two weeks later.
Tell the truth.
This time is not too outrageous.
After all, the gravity gradiometer has clearly detected the structure of the tomb chamber, and the target range of the first phase of the project is also very small:
Only the apse was cut, and the remaining eight side halls remained intact.
In other words.
The only cultural relics that really needed to be protected during the entire process were the four coffins in the apse, plus the issue of air tightness between the apse and side halls.
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, the difficulty of preserving cultural relics is undoubtedly several steps lower than the normal excavation of imperial tombs.
The official official name for this cutting and excavation is relatively traditional, called [Yongling Underground Palace Phase I Excavation Project], which has no special characteristics.
However, Xu Yun and Lu Chaoyang privately gave it a codename:
[Homage to Louis XVI].
Two weeks later.
March 1, 2023.
It was early in the morning.
Xu Yun and others gathered at the Ming Tombs Park again.
They are still the same people as two weeks ago, but the equipment around them is completely different from before.
For example, outside the treasure city of Yongling, there are many large-scale equipment and clearly divided preparation areas.
"Director Jiang, Academician Pan, these are the construction sites we have prepared."
Outside Baocheng.
A group of people led by Zhang Ziang were wearing safety helmets and walking around the construction site.
Zhang Ziang first led everyone to several huge excavators, and patted the body of one of them with his palms wearing labor protection gloves:
"These excavators are the main equipment for our excavation this time. They are all Sany Heavy Industry SY205C, referred to as Sany 205."
"Its length, width and height are 9680×2980×3440 mm respectively, with a tonnage of 21.5 tons and a bucket capacity of 1.1 cubic meters."
"Until it is dug 27 meters underground, it is the protagonist of this phase of the project."
Xu Yun raised his head and glanced at this behemoth. While sighing at the huge size, he also had a question:
"Academician Zhang, are we going to rely on these excavators to dig holes this time?"
Zhang Ziang glanced at him and asked with a smile:
"What, Dr. Xu, do you think they are not efficient enough?"
"No, no, no, I'm not talking about efficiency."
Xu Yun shook his head quickly, made a height gesture in the air with his hand, and said:
"This is Sany 20205, right? You can tell by looking at it that the work efficiency is not low, but its arm doesn't look very long. I guess it can only dig about five to six meters, right?"
"But the depth of the apse is 27 meters on the surface alone. How can we dig to the position of the apse with just the length of the 205mm arm?"
Hear this.
Lu Chaoyang, Huang Yuting and even Academician Pan beside Xu Yun all showed vague curious eyes.
What Xu Yun said happened to be their question as well.
Then Zhang Ziang glanced at Xu Yun and did not give a direct answer. Instead, he asked Xu Yun:
"Dr. Xu, since you think the excavator's robotic arm is not enough, in your opinion, what equipment should be used for this kind of project?"
Xu Yun subconsciously replied:
"Of course"
As a result, I just finished saying these three words [of course].
He suddenly got stuck.
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 isn't right either.
Although this thing is used underground, it is mainly used for lateral digging, such as tunnels or subway passages, etc.
How about explosives?
This is 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 subway platforms to underground shopping malls, the depth is basically about ten or even twenty or thirty meters.
So it stands to reason.
If there was a kind of equipment specially designed for digging underground facilities, it's impossible that he hadn't seen it before.
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 expression with a hint of confusion, Zhang Ziang couldn't help but smile and pat him on the shoulder:
"Dr. Xiao Xu, as the saying goes, there is a certain order of learning, and there is a specialization in the art."
"I may not be as good as you professionally and academically, but in terms of architectural knowledge, your knowledge may be limited."
"Let me tell you the answer. The excavation equipment used in underground projects are all this type of excavators!"
After that,
Zhang Ziang paused, organized some words, and continued:
"This excavation method is called open excavation, and it is common in projects with a depth of no more than 40 meters. There are many classifications of open excavation methods. The one we used this time is open excavation without grading."
Then Zhang Ziang scanned the surrounding area and quickly locked on a target.
I saw him pointing at several large drilling equipment not far from the crowd, and continued to explain:
"No, have you seen those green pile drivers?"
"Once construction begins, they will drill holes around the area where we are going to dig, and then enclose the area with cast-in-place piles - the main purpose of which is to increase the resistance to soil pressure."
"A similar link is that Shisui is not the Uchiha Shisui, it means to prevent water from penetrating."
"After doing this, you can start digging."
"As for what Dr. Xiao Xu said about the insufficient length of the robotic arm, our solution is to dig 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 calculation formula for load force, and the related technology is already very mature."
"With a depth of thirty meters, as long as our initial excavation area is large enough and about four floors are erected, we can dig to the upper level of the apse."
All classmates who have been civil servants in this life should know this.
The key point of digging a hole, to put it bluntly, is actually two words:
Envelope construction and waterproofing.
After all, everything is under pressure, and soil is certainly under pressure.
To put it simply.
If you dig out the soil in the middle of a piece of land, the soil next to it will be squeezed into the middle.
If too much soil is dug, the squeezing force will be too great and exceed the friction between the soil and the soil.
Then the position of the soil will be severely displaced, causing the foundation pit to collapse, and eventually causing an engineering accident.
The retaining structure mainly plays the role of balancing the earth pressure and preventing accidental collapse of the foundation pit.
However, the building envelope sounds simple, but in fact there are many types.
For example, what are the bored piles, ground-connected walls, steel supports, concrete supports, etc.
Nowadays, various types of underground facilities are commonly used, mainly the support form of bored piles + concrete supports + steel supports.
The first step in this method is to drive the piles with a pile driver. The soil removed from the pile driving will be thrown into a pre-made slag pool and then checked out at night.
After driving the piles, the engineering team will hang a steel cage into the hole - a long, black, thick and hard huge hollow steel column. After the steel column is stuffed into the hole, it will start to move into the hole. Pour sticky concrete inside.
After these pillars are completed, excavation can begin.
When the excavation robot 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 Mr. Ya, the author of "Golden Finger Came After I Became Emperor" for providing his professional knowledge)
The group then continued walking, chatting as they walked.
Zhang Ziang also introduced the water-stop curtain, slag pool, welding machine shed and other facilities to Xu Yun and others, giving everyone a general understanding of the construction overview.
About ten minutes passed.
Everyone stopped in front of another huge piece of equipment.
This is a giant transport truck about 20 meters long. It has a gray and white body and looks quite domineering.
However, what really attracts the attention of passers-by is not the body of the transport vehicle, but a green metal folding bracket placed on its lifting platform that is longer than the vehicle body.
Even a medium-sized excavator like the SY205C is like an ordinary fat man in front of this giant transport truck - a small fat man meets a big fat man.
If you meet an interstellar player with poor eyesight, Bao Buqi will think of this vehicle as a Dongfeng transport vehicle.
Face this real behemoth.
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 surprise of Academician Pan and others seemed to be of great benefit to Zhang Ziang, who also reached out to pat the outer shell of the vehicle and said proudly:
"Everyone, didn't I say something before - before the apse was excavated, the protagonist at the scene was SY205C."
"And the car in front of you is the protagonist of our second half."
"It is the ZAT18000H crane produced by Zoomlion. 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 this:
"Crane?"
Then Weng Tong looked at Zhang Ziang suspiciously and asked this old acquaintance:
"Old Zhang, do you call this a crane?"
"Let me tell you, the people around you today have a lot to read. They are either academicians, professors or 985 PhDs. Don't lie to us."
"The cranes in my impression are all large crawler-type equipment, or a gantry crane that looks like a small bench magnified 10,000 times. When did cranes have this style?"
Zhang Ziang glanced at him with disgust, 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. Well, Baidu has searched it for you in advance. Let's take a look."
Weng Tong:
"."
Everyone:
"."
Was this predicted?
Then Weng Tong took out the phone and looked at it a few times, then raised his eyebrows in surprise:
"Hey, is this really a crane?"
Zhang Ziang snorted coldly, looking a little arrogant:
"Of course, don't think about it, can I lie to you at this critical moment?"
"This crane is specially designed for land wind turbines. The operating environment is often in the wild, so it has strong off-road characteristics in appearance and performance."
“Isn’t the picture of SpaceX’s starship erected very popular? It is also famous for the huge crane on the side - it is the Liebherr LR11350 crawler crane of the Deutsche 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 quality can reach 1,800 tons. It is currently ranked first in the world."
As soon as Zhang Ziang said these words.
Everyone looked at this ZAT18000H with a different look.
Oh my god.
1800 tons
To know.
The density of one cubic meter of reinforced concrete is 2.5 tons.
The average floor slab thickness of residential buildings is 0.2 meters, so the weight of the floor slab per square meter is about 0.5 tons.
Then add the weight of walls, room equipment, etc.
The total weight of a commercial house that is about the same size as the apse is between 5 and 10 tons - the kind that is packed with goods is another matter.
Although there are coffins and stone platforms in the apse where the Jiajing coffin is located, no matter how heavy the entire apse is, it will never exceed 20 tons.
in this case.
Zhang Ziang took out the 1800-ton ZAT18000H
At this moment.
There is only one sentence floating in everyone's mind:
Killing a chicken with a bull's-eye.
This tmd can no longer be described as stable, okay?
Think of this.
Huang Yuting couldn't help but give a thumbs up to Zhang Ziang and said in admiration:
"Academician Zhang, you are too steady. It seems that we younger generations still need to study more."
"If I were to make the plan, I would estimate that even a 300-ton crane would be over the limit."
Zhang Ziang glanced at her. Facing this unfamiliar girl, he was no longer 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."
"At first we planned to use another smaller crane with a lifting capacity of only 500 tons, but"
Zhang Ziang didn't finish speaking.
Huang Yuting then answered with enlightenment:
"But out of a sense of mission for the Yongling excavation, you temporarily changed it to the more secure ZAT18000H?"
Zhang Ziang glanced at her and shook his head quickly:
"No, it was Manager Huang from Zoomlion who found me and said that if the ZAT18000H can be shown in this excavation live broadcast, they will provide me with a batch of advanced equipment for free for another excavation project."
Huang Yuting:
".?"
all in all.
After introducing the ZAT18000H crane.
Zhang Ziang's circling session was almost officially over.
At this point, everyone has a rough idea of the entire project plan.
Then everyone returned to the temporary headquarters and made final preparations.
More than twenty minutes passed.
The on-site assistant sent the message:
All units are officially in place.
Jiang Chenggu walked to the temporary workbench, looked around at the construction representatives and media representatives, and said:
"Dear distinguished guests, dear colleagues and fellow workers, hello everyone!"
"I am Jiang Chenggu from the GWY General Office. Today we are very honored to welcome the opening ceremony of the first phase of Yongling, an important national project to excavate the Ming Tombs."
"As one of the representatives of the group of royal tombs in ancient China, the Ming Tombs have a long history. It has witnessed the changes of dynasties and carries a profound historical and cultural heritage."
"And Yongling is an extremely important tomb among the Thirteen Tombs."
It turns out.
Even Jiang Chenggu, a seemingly capable official, was very inefficient in his speeches and couldn't escape from the clichés.
It took him more than ten minutes to finish speaking a bunch of useless but essential content.
After the speech, it’s
The lottery link.
As everyone knows.
It is different from the so-called foundation laying "custom" of a group of people shoveling sand into the marble sand pit for foundation laying projects.
The "jackpot" of an archaeological excavation project is exactly the opposite process:
It involves a group of people dancing with hoes to dig out previously buried things from a shallow layer of soil.
This custom is the same as the pig head sacrifice at the beginning of the movie. Strictly speaking, it is not a feudal superstition - these days, there are still people who worship electronic pig head photos, and it is more about seeking luck.
The same is true for this excavation of Yongling.
So it's quick.
Jiang Chenggu, Academician Pan, Zhang Ziang, Weng Tong and Tong Huaijun carried hoes and walked to a soil layer.
Then they waved their hoe a few times and successfully dug out a piece of white silk of the same style as Chongzhen, and selected a lucky viewer to give it to a live broadcast platform.
Finish these.
The excavation project of Yongling officially started.
Boom boom boom——
The roar of equipment soon sounded on the construction site, and the smell of sand and gravel gradually filled the air.
at the same time.
There are also many melon-eating viewers in the major live broadcast rooms.
How powerful Chinese netizens are, this can be seen from the fact that millions of people on the Internet watched the live broadcast of the construction of Huoshenshan Hospital.
Of course.
Compared with previous major events, the number of people attending the live broadcast of Yongling Excavation is still much smaller.
From the very beginning.
The actual number of people watching the live broadcast on the entire network is probably around 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, and it is basically considered a hot news.
Therefore, Xu Yun had some time to take out his mobile phone and took a look at the hot searches on Weibo.
Sure enough.
#YonglingConstructionLive# This hot search has rushed to the second place, second only to the first place and the popular national examination results.
When the national exam fever dissipates tomorrow, the topic may still have a chance to reach the first place.
Then Xu Yun clicked on the topic square again.
Sure enough.
At this time, you can still see a lot of criticism in the square, basically all of which mentioned the Dingling tragedy.
But it is 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. He had seen similar remarks in the past few days.
After scanning these discussions, he continued to read other news.
But look at it.
His expression suddenly froze.
I only see this moment.
At the 17th hot search position on Weibo, there is a topic:
#This Year’s Life Prisoner Xu Yun#
Xu Yun:
"."
What the hell is this hot search tmd?
Then he clicked on the topic and found a personal user's news hanging in the square:
【Little Tongtong who loves Zhang Ying】：
[Protruding (艹三艹), what exactly is going on this year? There have been so many major events since the beginning of the year. Except for Mikami Yua's retirement, all of them are related to Xu Yun. Did I kill Xu Yun this year or something happened? 】
At this moment.
The number of comments on this Weibo has exceeded 6,000.
For a personal account that is not a big V and has only more than 2,000 fans, this is undoubtedly a "big bang" data.
It’s just that Xu Yun felt a little uncomfortable watching this content
What does Xu Yun mean?
Is it a big deal to co-write with me?
Then Xu Yun hesitated for a moment, and with a very subtle mentality, he reached out and clicked on the comment area of this Weibo.
The top-ranked comment has no text content, but an emoticon.
As a result, the moment he saw this emoticon, Xu Yun couldn't stand it any longer:
"Your uncle!"
I saw that the content of this emoticon was not a panda head or a celebrity, but it was
Xu Yun himself!
In this picture, Xu Yun slightly hunched his neck and shrugged his shoulders, with the corners of his mouth drooping down, feeling inexplicably in need of a beating.
At the same time, the person who took the screenshot also added the three words "啾啾啾啾" in the picture, which seemed to be as mocking as possible and inexplicably a bit unworthy of 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 Atsushi Suzuki that the atomic bomb would explode twice, he seemed
Have you really done this?
At present, the number of likes of this comment has reached 12,000, and there are more than 300 replies.
The contents are basically comments such as "Good Picture", "Collected", "Bangzi Flag.JPG" and the like. The level of harmony is as harmonious as the good posters under the pornographic film link.
Ding dong——
Just as Xu Yun was scrolling through Weibo.
Suddenly he received a message on WeChat.
The message pop-up window 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 the cockroach lady Chen Shanshan, and the content of the message is clearly.
Xu Yun just saw this emoticon package.
Xu Yun: "."
Your uncle(╯‵□′)╯︵┻━┻!!!
Although the account balances were thousands of miles apart, at this time Xu Yun inexplicably understood Sha Cong, who had become famous because of a hot dog photo
Then he stuffed his phone back into his pocket and simply ignored it.
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 out the location of the apse?"
Zhang Ziang raised his head and glanced at the construction site in the distance, considered it and said:
"The three processes of drilling, placing steel cages, and pouring concrete are essential. From drilling to concrete solidification, which refers to the final setting, it takes at least two days."
"In addition, we need to build at least four layers of steel supports, which is four times of reinforcement."
“Including the total time for pressurization and voltage stabilization, it takes several days. In the whole process, the time spent by the excavator digging is the shortest.”
"Put it all together. If it's fast, it will take twelve or three days. If it's slow, it will take about three weeks. We should be able to dig to the top of the apse." (I calculated this time by checking the data myself. Is there any classmates in the industry who can give me some advice? Unreasonable? I’ll change it if it’s unreasonable)
"Of course, if we work in three shifts to rush the work, we can get it done in the short term - but this is combat readiness efficiency regardless of cost. At least our current plan does not consider this possibility."
"After all, Jiajing will not be resurrected if it takes a few days, and it is not allowed to become a spirit after the founding of the People's Republic of China."
Only then did Xu Yun realize.
Judging from the two weeks of excavation to the area where the apse is located, it should not take too long for the apse and copper hall to be unearthed.
That is to say
It won't take more than a few days.
"Yongle Dadian" can truly appear in the world.
The biological clock that I just adjusted hasn’t completely turned over yet, and I’m feeling a little uncomfortable, so I’m typing these first. I’m just short of a few hundred words or 9,000, and I’ll make it up tomorrow.
