Into Unscientific

  Chapter 504 "Yongle Grand Ceremony". Present! ! (Down)

   Right now.

on the ground.

   Following Zhang Ziang's order.

  Boom boom boom—

  The ZAT18000H crane, which has been fully deployed, quickly started working under the command of the operator.

  Actually speaking of the ZAT18000H crane, one of its parts has to be mentioned:

   That's its torque limiter.

  Different from ordinary self-propelled jib cranes.

  After the self-propelled jib crane enters the work, it is easy to make mistakes on the torque limiter.

  Torque limiter, also called torque limiter, safety coupling, or safety clutch, is a component that connects the main machine and the working machine.

  When the required torque exceeds the set value due to overload or mechanical failure, it will limit the torque transmitted by the transmission system in the form of slipping.

  After the overload condition disappears, the coupling will be restored.

  This prevents mechanical damage and costly downtime.

  However, in actual operation, the torque limiter of many cranes is often ignored before starting due to various reasons, which will increase the risk of accidents and even directly cause risks.

  So in order to avoid problems in this link.

  At the beginning of the design of ZAT18000H, a chip is added in the thread of the torque limiter, and the torque limiter is monitored by electronic means.

  So during the operation of the equipment, the operator only needs to pay attention to the parameters on the display screen.

Of course.

   Regarding this chip, there is another statement circulating in the crane industry that has never been acknowledged by Zoomlion:

   With one more chip, you can sell it for more money

   In Xu Yun's view, this statement is purely baseless speculation.

   After all, ZAT18000H cranes are mainly supplied to foreign merchants. How can we deceive those foreigners? What about foreign friends?

What?

  You ask what happened to the Camel Krypton Gold deal more than 30 years ago? What happened to those orders at last year's air show?

  Ahem, let’s take a look at the distant Himalayas, my family.

all in all.

  With the start of the ZAT18000H crane, everyone's eyes on the site were locked on this behemoth at the same time.

   Mentioned earlier.

  The highest jib height of the ZAT18000H crane can reach 140 meters, which is equivalent to the height of a fifty-story building.

  However, what it wants to lift today is only a single-digit tonnage 'small object' located about 30 meters underground.

  Therefore ZAT18000H naturally does not have to go all out.

  In this lifting project.

  Zhang Ziang and others preset the boom height to 44 meters, and the soil layer in the area where the crane is located has also been reinforced in advance.

  With the support device of the crane itself, there is no error or omission in safety.

five minutes later.

  The operator above the ground sent a reply:

   "Academician Zhang, the supporting weight of the crane, the hook group, the coupling, and the brake are all in working condition. Please convey the next step instruction!"

  Hearing this, Zhang Ziang exchanged glances with several engineers around him, took a deep breath, and ordered:

   "Non-staff personnel are evacuated to the safety zone of the upper foundation pit, and the ground is hooked!"

   Finished speaking.

  Zhang Ziang led the crowd back to the upper level of the foundation pit along the **** of the bottom foundation pit, and came to a safer area to "watch the battle".

at the same time.

on the ground.

  The jib of the ZAT18000H crane quickly dropped four leather hooks.

   Several technicians who remained in place quickly fixed them to the load-bearing plates that had been placed at the bottom of the apse in advance to support the entire apse.

   This load-bearing plate is a composite plate composed of multiple structures, the top layer of which is tungsten carbide.

   Tungsten has a nickname, called industrial teeth.

   means that it can chew anything.

  So the most common applications of tungsten are machining tools such as turning tools and milling cutters on lathes, and drill bits for mining.

   And tungsten carbide is a hard and brittle compound containing tungsten.

  This compound has very high hardness, Mohs hardness can reach 9-9.5.

To know.

  The Mohs hardness of diamond is only 10.

  Tungsten carbide is commonly used in various knives, armor-piercing projectiles and aircraft carrier decks. It has high hardness and strong compression resistance.

   But this thing also has a fatal problem:

  Although it is difficult to deform, once the deformation occurs, it is easy to cause the overall fracture.

   Therefore, in addition to tungsten carbide for the load-bearing plate, Zhang Ziang and his team also added cubic boron nitride and aramid fiber to the middle layer of the load-bearing plate, and used silicon carbide as the backing.

Under normal circumstances.

  Not to mention an apse that has been emptied of water, ten ears can be placed on it without crushing the bearing plate.

ten minutes later.

  The four hooks were firmly fixed to the four corners of the load-bearing plate with hydraulic equipment, and the technician checked it carefully again before reporting:

   "Report! The hooks are all in place, the stress test is normal, and the TOE coefficient check is correct. Please give instructions!"

  Zhang Ziang looked up at the ground above, and a flash of determination flashed in his eyes:

   "Very good, all departments pay attention, start now. Start raising the tone!"

  ka—

   Following Zhang Ziang's order.

  The operator of the ZAT18000H crane quickly pressed the start button, and the boom of the whole unit began to lift upward slowly.

at the same time.

  Including Weng Tong and Tong Huaijun.

  A group of archaeologists also brought some equipment to the edge area of ​​the second floor and entered a standby state.

  Once an accident occurred during the lifting process and the structure of the apse collapsed, they would immediately step forward to rescue the cultural relics or, to put it bluntly, the coffin.

   Then under the watchful eyes of a crowd.

  The boom of the crane slowly raised the apse from the ground with the apse. As the height increased, some clods of soil continued to fall around the apse.

  However, these clods are just ordinary dark brown soil, which means that the marble structure inside the apse has not been damaged.

  Three meters

  5 meters

  Eleven meters.

  Twenty meters.

  25 meters

that's all.

  The boom and the apse rise higher and higher.

   Finally, under the watchful eyes of everyone, it rose above the ground smoothly.

   Then the boom moved to the left, and not long after everyone lost their vision, there was a shocking sound of a heavy object falling to the ground on the left.

   Following that, there was another cheer that was not particularly enthusiastic but very clear.

at the same time.

  The communication device on Zhang Ziang also rang:

   "Academician Zhang, the apse has been successfully relocated to the preset resettlement site. There were no accidents in the whole process. Please issue instructions!"

   "Very good, everyone has worked hard."

  Zhang Ziang relaxed slightly, wiped the fine sweat from his forehead, and said:

   "You are on standby now and do a good job of protection. Director Jiang and the others will go up soon."

  After hanging up the communication.

  Zhang Ziang looked at Jiang Chenggu again, and said to him:

   "Director Jiang, I will leave the above situation to you first, I will stay here and try to dig Yong Yong as soon as possible"

   Said here.

  Zhang Ziang paused suddenly.

   He glanced at Weng Tong at the side, and changed his words:

   "Strive to dig out the copper temple where those blank pages are stored as soon as possible."

  Jiang Chenggu and Xu Yun:

  “.”

  After that, Jiang Chenggu and Zhang Ziang parted ways, and returned to the ground with everyone.

   Right now.

  In an open space about 50 meters away from the foundation pit, there is a newly unearthed head of Jiajing. Wrong, the apse of Jiajing.

  The area of ​​the apse is about the same as what Xu Yun and the others saw when they cleaned it up. It is more than 100 square meters in total, neither too big nor too small.

   As for the height of the apse.

  In fact, it has also been tested for specific values, but when it falls to the ground at a height of nearly seven meters, it still looks a bit bluffing.

  The moment I saw this apse.

   Weng Tong, Tong Huaijun, and several other archaeologists immediately packed their bags, separated from the crowd, and quickly trotted towards the apse.

  Their movements are as fast as seeing the group of friends sharing a mysterious connection, and they can't wait to open the Thunder software, completely ignoring the existence of other people around them.

  “.”

  Looking at Weng Tong and the others who left only shadows in a flash, the corners of Jiang Chenggu's mouth twitched twice, and explained:

  “. That’s all for archaeologists, please be more patient.”

   "After all, this is the first ancient emperor's tomb to be excavated in more than 60 years. It still contains the emperor's coffin. Professor Weng and the others may not be able to bear it."

  Academician Pan smiled at Jiang Chenggu, and took the initiative to comfort him:

   "It's understandable, it's understandable. Director Jiang, to tell you the truth, we often do this kind of thing in scientific research."

   "Sometimes we hear that which team has achieved something. If the conditions for reproduction are not very complicated, most of us will put down the leisure things at hand and do experiments."

   Hear this statement.

   Lu Chaoyang, Xu Yun and others on the side also nodded.

  Academician Pan's remarks were really not to give Jiang Chenggu a step down, but to understand Weng Tong's feelings.

  For example, before Dias claimed to have achieved room temperature superconductivity, teams at home and abroad immediately launched a reproduction experiment a few hours later.

  For example, Cheng Jinguang’s team at the Institute of Physics, some members were still playing games at the time, so they were called to the laboratory urgently.

  So on March 9, 2023 at around 8:00 pm in the Ionian Smash Bros., don’t be in a hurry to curse when you meet a friend who Xin Zhao disconnected from.

   By the way.

Up to now.

  In China, the team of Professor Wen Haihu, the team of Researcher Cheng Jinguang, and the team of Researcher Jin Changqing of the Institute of Physics have falsified the experimental results of Dias.

Of course.

  Dias was also vaccinated, saying that the doping of nitrogen must be controlled very finely.

  In addition, under normal circumstances, the combination of Lu elements and H elements to form LuH3 generally requires a high temperature of more than 650°C, but Dias successfully prepared Lu-H-N at 65°C and refused to disclose the principle. Maybe it is the manifestation of Shiva.

   As the saying goes, sincerity leads to success, cough cough

alright.

  The line of sight returns to reality.

   Then Jiang Chenggu took a group of people for a short walk, and soon came to the area where the apse is located.

   Right now.

  Weng Tongzheng and Tong Huaijun stood beside the apse, holding a prop that looked like an electric mosquito swatter, and kept waving it at the shell of the apse.

   Seeing this, Xu Yun stopped a few meters away from them, and asked curiously:

   "Uncle Weng, you are here."

  Weng Tong turned his head and glanced at him, pointed to a digital display screen on his waist and explained:

   "This is an air-tight detection device. There are high-sensitivity sensors around the side, which can detect the air flow on both sides."

   "If the circulation figure in any area is higher than 0.07P, which is the value of the normal windward side, it means that there is a gap there."

   "In this way, we must fill the air gap in time."

   "It turned out to be like this"

  Xu Yun nodded thoughtfully, then looked around, and asked again:

   "Then Uncle Weng, when will the apse be opened?"

  Although Jiajing’s remains in the emperor’s coffin have most likely turned into dead bones, the ‘elixir’, ‘emperor’s crown’ and Jiajing’s feather coat in the coffin are all very precious cultural relics.

  If you don’t open Yongling, it’s okay.

  But now that the Yongling Mausoleum has been opened and the apse has been moved to the ground, these things must be taken out.

   "Open the hall?"

  Weng Tong stopped his movements when he heard the words, patted the side wall of the apse, and said to Xu Yun:

   "Although there are not many cultural relics in the apse, considering our current open-air conditions, at least we have to wait until the copper hall is dug up before opening it."

   "After all, there is a lot of external pressure. Once the cultural relics are damaged, it is estimated that many trolls who have not made a sound will emerge."

   "Besides, what we are going to do is indeed a protective excavation. Opening Jiajing's grave is a bit sorry for others. Their bones must be protected no matter what?"

  Xu Yun thought about it, and it seems to be the reason.

  Due to professional barriers, he is not very clear about the process of cultural relics preservation.

However, according to a lot of information he has seen before, many cultural relics are generally oxidized very quickly after being unearthed—although they will not turn into fly ash in the blink of an eye, but basically serious damage will occur within 1-3 minutes. Shape issues.

   Therefore, how to ensure that the emperor's coffin, the 'elixir' inside the emperor's coffin, the emperor's crown, and even the remains of Jiajing and the four empresses will not be damaged, these are the links that need to be carefully discussed.

   Perhaps in the past period of time, Weng and them have discussed specific plans, but most of them don't seem to be low-tech actions that can be done in the open air.

   Figured this out.

  Xu Yun kept his voice down obediently, and watched Weng Tong's inspection from the sidelines.

   I don't know if it was luck.

   There is no structural problem in the apse where Jiajing’s coffin is located. The marble inside the tomb is very tightly fitted, even much better than the previous Dingling.

   Some engineers believe that this has something to do with the arched structure of the apse. After all, the arched structure is a well-known bending member, and the structure is quite stable.

  When the accumulated water is not fully capped, the entire apse is actually equivalent to the bottom of the arch bridge.

  So it is not difficult to understand that there is no structural damage in the apse.

   After about an hour.

  The soil layer of the apse has been completely cleaned up,

   With the cooperation of the staff, the entire building was sealed with another foamed silicone material with strong airtightness.

   Finish these.

  Xu Yun followed Weng Tong and others back to the bottom of the foundation pit.

  Students with good memory should remember.

  During the excavation of the apse, the left, right, and rear sides of the back were all excavated directly to the bottom.

  So when the apse was hoisted by a crane.

   There is no need to expand the space of the foundation pit, and the excavator can directly land on the open space on the left, right and rear sides and start digging down.

  In addition, the bottom area of ​​the Bronze Hall is only more than 60 square meters, about the size of a high school classroom, so the entire excavation progress is still very fast.

   Less than two hours.

  The bucket of the excavator successfully dug half a meter above the copper hall.

   Here we go.

  The next thing is very simple.

  Zhang Ziang and others carried out a round of re-engraving exactly the same as the apse—first, the four sides were excavated by machine, and the top of the copper hall was excavated manually.

  Although he was exhausted in energy, Xu Yun insisted on becoming a member of the artificial team.

   After all, life is to have a sense of ritual.

   Compared with the soil layer of the apse, the soil in the area where the Copper Hall is located is obviously wetter. As for whether it is caused by the infiltration of the underground palace of the Nine Palaces or the groundwater, it is not known.

   "Hey!"

  Xu Yun rolled up his sleeves and dug down for about ten minutes, when the shovel suddenly shoveled something hard, and there was a dull metallic sound on the contact surface.

  Xu Yun was startled when he saw this, and quickly pulled the soil a few times.

   After a while.

  A metal surface buried in the soil layer appeared in front of him.

  Due to wet soil.

  The metal surface is covered with a thick green rust spot, and an ancient atmosphere that has been dusted by the years suddenly rushes towards the face.

  Although Xu Yun is not a top student majoring in chemistry, he recognized the identity of the rust spot at a glance:

  Basic copper carbonate.

   This thing is a standard product of copper in a humid environment, and it is often found on the surface of bronzes in wet soil and in the fanfiction of the "Shading the Sky" novel.

  The treatment of patina is actually very simple, just soak it in vinegar for a day, and then clean it with a brush.

Of course.

  Seeing this, some students may have questions:

   No, isn’t it that the copper temple in Wudang Mountain is also made of pure copper? Why hasn’t it rusted after hundreds of years?

the reason is simple.

  The inside of the Wudang Mountain Copper Hall is made of copper, but the outside is covered with gilt.

  In ancient times, gilt was made by mixing gold and mercury, and then heated to evaporate the mercury, so that the gold can be adsorbed on it and not easy to fall off.

  Thus hundreds of years passed.

   There is no rust on the surface of the Wudang Mountain Copper Hall, but the color of the bronze statue has changed to a copper color, so it is also called a copper statue.

  The line of sight returns to reality.

  Although Xu Yun really wanted to get rid of the patina now, he still maintained his basic rationality.

  The current situation is the same as the previous apse. The Copper Palace is not suitable for disposal in the foundation pit—after all, the things inside the Copper Palace are more important.

  So he could only draw his attention back to reality, and continued to manually clean up the sand.

after an hour.

  The sand and stones on several sides of the copper hall have been cleaned up, and the appearance is fully presented to everyone:

   This is a large copper box of about 7X7X3. The outside is covered with a patina that is very unfriendly to patients with trysophobia. It looks inexplicably permeable.

  But Zhang Ziang didn't care about it.

  He reproduced the previous operation very calmly, and let the ZAT18000H crane hoist the copper palace to the ground again.

   Compared with the larger apse, the Copper Hall is much less difficult to operate.

   Also within a few minutes, it was safely placed on the ground by the crane.

  “.”

  Xu Yun paid close attention to the whole operation, but what surprised him was that

   After landing in the Copper Temple.

  He did not receive notification about the completion of the "Yongle Dadian" task.

   Murphy

  The "Yongle Dadian" mentioned by the halo does not mean that the book was unearthed.

   Instead

  The books are to be taken out of the bronze temple intact?

Note:

   Let me talk about a very outrageous thing. I checked a lot of crane-related data in the past few days—especially the quotation, and then I received a call yesterday, asking me if I want to buy a crane

  The update will start tomorrow.
