Just as the heavy-duty helicopter reached a technical cooperation agreement and the Z-30 project was officially launched, on the other side, other disaster preparedness work also began to proceed in an orderly manner.
In Yingxiu County, a special team entered the county town carrying various instruments.
On the surface, they were performing a mineral exploration mission, but in fact, they were trying to explore the main geological structures within a 15-kilometer radius centered on Yingxiu within a month, and select the location of the "seismic shield." Construction scope.
Near Yingxiu Zuji Ditch, exploration team leader Zheng Jiuyuan took off the heavy equipment on his shoulders, wiped the sweat from his forehead and said:
"It should be right here, 31 degrees north latitude and 103.4 degrees east longitude."
“It’s really rare to find a car with such accurate location.”
"I certainly haven't seen it before."
Team member Zhong Jian on the side carefully placed the backpack-type portable drill on the flat ground, and then continued:
"If we go back thirty years, I remember that we were still very keen on predicting earthquakes at that time, but now... we haven't heard of such a thing for many years."
"If the order hadn't come directly from the working group, I would have thought it was a joke."
Hearing his words, Zheng Jiuyuan nodded slightly.
"It's all the same. As long as they are really doing geological work related to earthquakes, I don't think anyone can believe in earthquake predictions."
"Earthquakes are a typical chaos model, and there is no directly observable indicator system. With our current technical level, even predicting the probability is extremely difficult, let alone accurately predicting the three elements."
"I have always felt that the earthquake in Haicheng was purely an accident that killed the mouse - and there was indeed no successful case in the end."
"But this time, it feels like it's serious."
"How to say?"
Zhong Jian asked curiously.
"Have you read the news? Recently we signed a heavy-duty helicopter import contract with Russia, and the outside world is guessing what these heavy-duty helicopters will be used for."
"Some people speculate that there is a big movement on the border, and some people speculate that it will be deployed to Djibouti in Africa to build armored airborne troops."
"But these people obviously didn't get the idea. If you combine what we are doing now, it is obvious that these helicopters are used for disaster relief."
"This is a large order of nearly 1.5 billion yuan, and the investment is scary."
"If it is not a certain matter, the official will not take this risk."
Looking at Zheng Jiuyuan's serious expression, Zhong Jian frowned thoughtfully, and then continued to ask:
"What if I just bought it by hand?"
"What I mean is, maybe the main purpose is military, and it can also be used as a backup."
"But looking at this one thing, it is indeed possible."
Zheng Jiuyuan took a breath and continued:
"But when you watch the news, you have to look at the whole picture."
"Recently, this is not the only big move taken by the authorities."
"Over at the Economic Port, superiors have issued several new notices, requiring some enterprises and institutions to do a good job of 'capacity reserve'. What does this mean? It means that two machines can do the work, but now the number of machines must be increased. To station 3.”
"Generally speaking, this kind of notice is issued for only two purposes."
"Either to indirectly stimulate economic growth, or to cope with the impact of major events in the future."
"We don't need economic growth - the current growth rate is fast enough."
"As for major events, the only major events that can be predicted are wars."
"Do you think it's possible for us to fight? It's impossible."
"So, it can only be a disaster."
Zhong Jian seemed to have been convinced by Zheng Jiuyuan, his expression became solemn, and then he asked:
"So you're saying that this earthquake is really possible?"
"I have no idea."
Zheng Jiuyuan shook his head and continued:
"No one can say for sure whether it will happen, but from a certain perspective, officials have indeed determined that this earthquake will happen."
"So, what we have to do is to keep secrets, use our abilities, and actively cooperate."
"You know, if that didn't happen, that would be a great thing because no one would die."
"If it happened, every minute we spend here, we might save more than one person."
"Then do it quickly."
Zhong Jian immediately stood up and began to assemble the portable drilling instrument quickly.
Two other team members with military backgrounds also stepped forward to assist. It didn't take long for the instrument assembly to be completed, and the two men immediately started drilling operations.
As the soil and rock samples deep underground were brought out of the ground, Zheng Jiuyuan couldn't help but sigh and said:
"Just looking at the environment of this location, the probability of an earthquake is really high. If it happens, the damage will be huge."
"This place itself is located on the thrust nappe tectonic belt. There are three major faults nearby. It is a stress concentration point where the two plates are squeezed. The accumulated stress on the nappe tectonic belt is definitely not small. It is normal for earthquakes to occur. matter."
"Coupled with the complex topography, unstable rock structure, and water and soil erosion here, once an earthquake occurs, a large number of slope instability will definitely occur."
"When the time comes, once secondary disasters such as intensive aftershocks, barrier lakes, and mudslides occur, the intensity of rescue operations will increase exponentially."
"It's no wonder that the official attaches great importance to it. This is really not a trivial matter."
Hearing his words, Zhong Jian temporarily stopped what he was doing. The roar of the drill became quieter, and he said:
"That has to actually happen. Anyway, I still hope this is just a misjudgment."
"Actually, the probability of misjudgment is quite high, estimated to be over 99%."
"But overall expectations are too high."
Zheng Jiuyuan interrupted him. Zhong Jian was stunned for a moment and then understood what he meant.
With a 100% probability, multiplied by the loss of an indicator of 1, the expectation is nothing more than 1.
But if the probability of 1% is multiplied by the loss of tens of billions, then the expectation will reach an astonishing hundreds of millions.
So, he sighed and said:
"Indeed. So we have to do our best."
"But having said that, do earthquake shields really work? I have never seen any country use this method to prevent earthquakes."
"It works, and it's very useful."
Zheng Jiuyuan answered without hesitation.
"The reason why you haven't heard of it is because the construction of the earthquake shield is too difficult and the amount of work is too large, so there is no way to implement it."
"But in fact, if we can delineate a certain area and build an earthquake shield structure in advance, as we have done, it can have a great effect."
"According to theoretical calculations, after combining the two methods of earthquake shield and surface vegetation cloak, earthquake Rayleigh waves can be reduced by at least 70%."
"With this level of attenuation, the destructive effect has been greatly reduced."
"Of course, the main thing we are talking about here is noodles."
"The damage caused by body waves is inevitable no matter what, but compared with Rayleigh waves, body waves are much less destructive regardless of their horizontal or vertical direction."
"We have no way to eliminate the body wave. We can only rely on the strength of the building to deal with it."
Zhong Jian was silent for a moment again, and then continued to ask:
"But the problem is that the transmission of body waves will eventually lead to the formation of surface waves. Even if our earthquake shield surrounds Yingxiu, it is still impossible to block most of the body waves, right?"
"That's why the range is 15 kilometers."
Zheng Jiuyuan explained:
"According to information from superiors, the focal depth of this earthquake is about 14 kilometers. With the source surface as the center and 15 kilometers as the radius, we can attenuate the Rayleigh wave as soon as it is formed."
"However, we are only conducting a preliminary investigation now. Depending on the situation in the future, the radius of the earthquake shield may be extended."
"By that time, the risk will be further reduced."
Zhong Jian nodded heavily and then said:
"It seems that the superiors have thought carefully this time."
"Yes, so we can't make any mistakes in execution."
After that, the two of them started exploring again.
In the county town not far from them, there was a peaceful scene
At the same time, near NPU, in Wang Jiancheng's laboratory.
Wang Jiancheng stood opposite Chen Nian and Qiu Mai, conveying the so-called instructions from "superiors".
".So, to sum up, our superiors asked us to upgrade the mechanical exoskeleton."
"The upgrade requirement is to further enhance the exoskeleton's power system, which requires a hydraulic weight lifting module."
"At the same time, the energy of the exoskeleton should be optimized and the latest high-density lithium batteries or other new batteries should be used."
"Under continuous operating conditions, the exoskeleton is required to have a battery life of more than 6 hours and be able to lift more than two tons of weight through the hydraulic lifting module."
"In addition, the exoskeleton is also required to have a certain degree of flexibility and be able to adapt to operations in a narrow range."
"Of course, robustness is also a must. It must be very durable."
Having said this, Wang Jiancheng paused for a moment, and then continued:
"These conditions sound quite difficult, but the rewards given by superiors are also very generous."
"We can directly use the cooperative department - that is, the mechanical laboratory of Norinco, and other materials are also provided by Norinco."
"As for personnel, there are more."
"In short, we will give you what you ask for, as long as the results are produced within the specified time."
"How about it, you two, think about it?"
After hearing Wang Jiancheng's words, Chen Nian on the side was not moved at all.
The reason is simple, this request was made by him.
The reason for such a requirement is also to adapt to the rescue environment in disaster areas.
In his previous life, he witnessed many people using their own hands to dig up the ruins until their fingernails fell off and even their bones were exposed.
He has also seen people holding up huge concrete slabs on their shoulders, just to bring a glimmer of life to the people underneath.
This situation makes people helpless and sad. In the corners that large machines cannot enter, "powerlessness" has become the reality that makes people cry the most.
——
However, things are a little different now.
Mechanical exoskeletons appeared early and their functionality has been verified.
So why can't we develop a dedicated exoskeleton based on this?
It does not need too complex functions, but only needs to do one thing: it can flexibly enter the ruins and lift heavy objects stably.
By doing these two things, most of the dilemma of "terminal rescue" will disappear.
Just as the scene of exoskeleton rescue flashed through Chen Nian's mind involuntarily, Qiu Mai on the side spoke:
“I can attend as a support worker, but I can’t do it full time.”
"As you know, the topic for my graduate school has been selected, and I will spend a lot of time preparing the project. I don't think I can spend too much time on this project."
"That's enough! I mainly hope you can solve the problem of the hydraulic lifting module, which you are familiar with."
Wang Jiancheng replied cheerfully.
He actually didn't expect Chen Nian and Chen Nian to devote themselves to it full-time. After all, this could be said to be his own project, and everyone else had other things to do.
"Senior, what about you?"
Upon hearing Wang Jiancheng's question, Chen Nian shook his head and replied:
"I won't participate. I can't help much."
"Then I'll put your name on it. It'll be useful in the future."
Wang Jiancheng said without hesitation.
".Fine."
Chen Nian was too lazy to give in too much to him, so he simply agreed.
However, looking at the excited expression on Wang Jiancheng's face, he couldn't help but asked worriedly:
"Do you have confidence in this project? I think the conditions are quite harsh, just in case it doesn't come true."
"It won't be impossible!"
Wang Jiancheng interrupted Chen Nian and explained:
"Senior, although these conditions are very complicated, in the final analysis, if you only look at the underlying logic, the equipment that the official wants to do is actually very clear."
"That is, the disaster relief robot."
"Look, flexibility, high endurance, hydraulic lifting."
"These three points have actually limited the application scenarios. In addition, the last one requires high stability in extreme environments. They even used AK47 as an example. What they really want is self-evident. bright."
“So, once you know the purpose, optimizing it is simple.”
"I already have a blueprint in my mind. As long as you give me the laboratory, I can have a prototype in less than a month."
After hearing this, Chen Nian finally felt relieved.
Wang Jiancheng is a kid. Although his mind is full of all kinds of seemingly unrealistic ideas, in fact, when it comes to doing things, he is still extremely reliable.
So, he didn't say any more, but just emphasized:
"Now that you can determine the purpose, remember to design it according to the purpose and don't go astray."
"rest assured!"
Wang Jiancheng nodded solemnly and replied:
"If it were something else, I might still have a playful mentality."
"But this thing will be used for disaster relief in the future, and I won't make any jokes about it."
"You can definitely rest assured on this!"
With Wang Jiancheng's promise, Chen Nian finally felt a little lighter.
After chatting about the details of the project, he said goodbye to Wang Jiancheng and left his laboratory with Qiu Mai.
Seeing that it was getting late, Qiu Mai suggested that they go out for a meal together. After all, they were about to graduate and it was time to have a sense of ceremony.
Chen Nian thought that this was indeed the case, so he walked out of the gate with her. However, just as he left the school gate, his cell phone rang.
After answering the phone, Chen Nian smiled apologetically at Qiu Mai, who also let him go in an understanding manner.
However, after he left, Qiu Mai's eyes were full of doubts.
She didn't know what happened to Chen Nian.
Chen Nian's eyes seemed to be shining with excitement.
——
I have never heard that he is in love.
Maybe, someone more important?
Qiu Mai smiled mockingly and walked out of the school gate.
But if she knew the content of that phone call, she would definitely feel that she deserved to lose.
Because the news that that phone call brought to Chen Nian was:
The new electromagnetic gun has completed experiments, its structure has been optimized, and it is ready to be put on the ship.
Introduction: Xu Shouyi traveled to the world of universal summoners, where summoners can summon various creatures and even equipment through summoning stones.
Xu Shouyi's summoning talent was average, but he accidentally discovered that he could communicate with other worlds and summon blind dates.
The first blind date: a human with superpowers who lives in a post-apocalyptic zombie world and is nicknamed the Gatling Bodhisattva.
The following blind dates: Hateful Married Girl, Desperate Housewife, Goddess Empress, Martial Arts Devil, Eight-foot Snow Girl...
Seeing so many blind dates, Xu Shouyi said he was not panic at all.
It's okay if I don't have the summoning talent. I'll summon my date with my backhand.
Unknowingly, he has formed an army of blind dates that is invincible!
