Chapter 492 Sure enough, Xu Yun was killed this year...
Jiang Chenggu's words can be regarded as a statement in his capacity as the general office.
In other words, the "beheading" plan proposed by Zhang Ziang was initially accepted.
Of course. This is 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? There is only one.
Although the two concepts are not actually comparable, they can be used 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 understands this very well.
Therefore, after the exploration team completed the exploration, 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, the excavation plan of Zhang Ziang's team is agreed, and the committee is requested to immediately start excavation preparations. China Construction Seventh Engineering Bureau will provide equipment assistance during the construction process.
The construction of the mausoleum will start in two weeks. To 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 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 1 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 they were 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. Their models are all Sany Heavy Industry sy205c, referred to as Sany 205."
"Its length, width and height are 9680x2980x3440 mm, the tonnage is 21.5 tons, and the bucket capacity is 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:
"Why, Dr. Xu, do you think they are not efficient enough?"
"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 the Sany 20...205, right? You can see from the head 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.
?』
"But the surface depth of the apse alone is 27 meters. How can we dig to the apse with a 205mm arm length?"
Hear this.
Lu Chaoyang, Huang Yuting and even Academician Pan beside Xu Yun all looked at him with faint curiosity.
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 soon as he said these three words [of course], he suddenly got stuck.
Drilling? Obviously impossible.
Although the depth of the borehole is deep, the area is very small, and it is mainly used for piling or sampling.
TBM? That’s not right either.
Although the usage scenario of this thing is underground, it is mainly used for lateral digging, such as tunnels or subway passages, etc.
How about... dynamite?
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 depths are basically about ten or even twenty or thirty meters.
So it stands to reason.
If there is a kind of equipment specially designed for digging underground facilities, it is impossible that he has not seen it.
But no matter what he thought at the moment, he couldn't think of a reasonable answer.
Could it be...that it's 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 hierarchy of knowledge, and there is a specialization of skills."
"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 underground projects are all this type of excavators!"
After saying 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?"
"After 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 - its main purpose is to increase the resistance to soil pressure."
"A similar link is Shisui... It's not the Uchiha Shisui, it means preventing water from penetrating."
"After doing this, you can start digging."
"As for Dr. Xu, what you said about the length of the robotic arm is not enough... Our solution is to dig in layers, that is, every few meters the excavator digs, it will enter the next layer and continue digging."
"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 my classmates who have been civil servants in this life should know this.
The key point of digging holes, to put it bluntly, is actually
Just two words:
Envelope construction and waterproofing.
After all, everything is under pressure, and of course soil is 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 squeeze 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 ultimately 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, there are bored piles, ground-to-ground 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.
This method starts by driving 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, hard and huge hollow.
After the steel columns are stuffed into the holes, sticky concrete will begin to be poured into the holes.
After these pillars are drilled, 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 "I Became Emperor, Golden Finger Came" for providing professional knowledge.
.....)
Then the group continued walking, chatting while walking.
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 Zath crane produced by Zoomlion. It is also one of the most advanced cranes in China... no, even in the world."
When everyone heard this, they couldn't help being stunned again: "Crane?"
Then Weng Tong looked at Zhang Ziang suspiciously and asked this old acquaintance:
"Old Zhang, you call this thing 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:
·....--
Is 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 onshore wind turbines.
The working environment is often in the wild, so it has strong off-road character in appearance and performance.”
"Isn't the picture of the spex company's starship erected very popular? It is also famous for the huge crane on the side - it is the Liebherr LR crawler crane of the Deutsche Liebherr Group.
, with a maximum rated lifting capacity of 1,350 tons, it is a little brother in front of our crane."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "The hoisting height of our Zath can reach 140 meters, and the hoisting quality can reach 1,800 tons, which is currently No. 1 in the world."
As soon as Zhang Ziang said these words.
Everyone looked at this Zath with a different look.
Oh my god.
1800 tons...you 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 the walls, equipment in the room, 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 1,800 tons of zath. At this moment.
There is only one sentence floating in everyone's mind: killing a chicken with a bull's-eye.
This can no longer be described as steady, okay...
Think of this.
Huang Yuting couldn't help but give Zhang Ziang a thumbs up and said in admiration:
"Academician Zhang, you are too steady. It seems that we juniors still need to study more."
"If I were to make the plan, I would estimate that even a 300-ton crane would be overkill."
Zhang Ziang glanced at her. Facing this unfamiliar girl, he was no longer as casual as he was with Weng Tong:
"...Um, 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 as if she had some understanding:
"But out of a sense of mission for the Yongling excavation, you temporarily changed it to a safer Zath?"
Zhang Ziang glanced at her and shook his head quickly:
"No, it was Manager Huang from Zoomlion who found me and said that if Zath can show up in this excavation live broadcast, they will provide me with a batch of advanced equipment for free for another excavation project.
....."
Huang Yuting: "n..·-.........In short.
After introducing the zath crane.
Zhang Ziang's circling session has almost officially ended. At this point, everyone has a rough idea of the planning of the entire project.
Then everyone returned to the temporary headquarters and made final preparations.
More than twenty minutes later, the on-site assistant came with news:
All units are officially in place.
Jiang Chenggu walked to the temporary workbench, looked around at the construction representatives and media representatives, and said
"I am Jiang Chenggu from the Gy General Office. Today we are very honored to welcome the opening ceremony of the first phase of the Yongling Tombs, 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..."
Facts prove.
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 lucky draw. As we all know.
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 sacrificing a pig's head at the beginning of the movie. Strictly speaking, it is not a feudal superstition - these days, there are people who worship electronic pig head photos. It is more about seeking luck.
The same is true for the Yongling excavation this time. So it was very fast.
Jiang Chenggu, Academician Pan, Zhang Ziang, Weng Tong and Tong Huaijun carried hoes and walked to a soil layer.
Then they waved the hoe a few times and successfully dug out a white silk of the same style as Chongzhen, and drew a lucky viewer on the live broadcast platform to give it to them.
Finish these.
The excavation project of Yongling officially started. Boom boom boom--
Soon the roar of equipment could be heard 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 live broadcast of the construction of Huoshenshan Hospital, which was watched by tens of millions of people across the Internet.
Of course.
Compared with previous major events, the number of people who live broadcast the 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.
as expected.
#YonglingConstructionLive# This hot search has rushed to the second place, second only to the first place and the popular national examination results.
When the heat of the National Examination dissipates tomorrow, the topic may still have a chance to reach the first place.
Then Xu Yun clicked on the topic square again. As expected.
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 as he looked at it, his expression suddenly froze. All he could see was this moment.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! There is a topic hanging at the 17th hot search position on Weibo:
# This year’s life-criminal Xu Yun#Xu Yun: ""
What the hell is this hot search t?
Then he clicked on the topic and found a personal user's news hanging in the square:
[Xiao Tongtong who loves Zhang Ying]:
[Two (艹三艹), what is going on this year? So many big things have happened since the beginning of the year. Except for Mikami Yua’s retirement, everything is related to Xu Yun. This year I am
Is Xu Yun guilty or something else 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 by life?
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.
Among them, the top-ranked hot comment has no text content, but an emoticon.
As a result, the moment he saw this emoticon, Xu Yun couldn't stand it anymore:
"Your uncle!"
I saw that the content of this emoticon package 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 drawn downwards, inexplicably feeling a little needy.
At the same time, the person who took the screenshot also added the words "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 something:
At the previous dark matter press conference, when he told Atsushi Suzuki that the atomic bomb would explode twice, it 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] [stick flag.jpg] and the like. The level of harmony is as harmonious as the good posters under the little *** 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 Cockroach Girl Chen Shanshan, and the content of the message is...
Xu Yun just saw this emoticon pack. Xu Yun: "..."
Your uncle (mouth)!!!
Although the account balances were thousands of miles apart, at this time Xu Yun inexplicably understood the man who had become famous because of a hot dog photo...
Then he stuffed the 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, thinking carefully and saying:
"The three processes of drilling, placing steel cages, and pouring concrete are essential. From drilling to concrete solidification...this refers to the final setting, which 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 stabilization, it takes several days. In the whole process, the time spent by the excavator digging is the shortest."
"Taking it all together... If it's six days if it's fast, and eight days if it's slow, we should be able to dig to the top of the apse." (I calculated this time by checking the data myself. Is there anyone in the industry who can give me some advice?
Is it reasonable? If it’s not reasonable, I’ll change it.)
"Of course, if we work in three shifts to rush the work, we can finish it in two or three days - 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 in a few days. After the founding of the People's Republic of China, he is not allowed to become a spirit..."
Only then did Xu Yun feel enlightened.
Based on the eight days 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.
In other words, it will only take a few days.
"Yongle Dadian" can truly appear in the world. Note:
