Chapter 292 Disaster preparation work is rolled out, and the electromagnetic gun is on board!

Just as the heavy-duty helicopter reached a technical cooperation agreement and the Zhi-30 project was officially approved, on the other hand, other disaster preparedness work also began to proceed in an orderly manner.

In Yingxiu County, a special team entered the county seat with various instruments.

On the surface, they are carrying out a mineral exploration mission, but in fact, they want to find out the main geological structures within a radius of 15 kilometers centered on Yingxiu, and select the "seismic shield" within a month. construction scope.

Near Yingxiu Zujigou, the exploration team leader Zheng Jiuyuan unloaded the heavy equipment on his shoulders, wiped the sweat from his forehead and said:

"It should be here, 31 degrees north latitude, 103.4 degrees east longitude."

"The position is accurate to this level of car, which is really rare."

"I really haven't seen it."

The team member Zhong Jian on the side carefully placed the backpack-type portable drill on the flat ground, and then continued:
"If you go back 30 years, I remember that we were still quite keen on predicting earthquakes at that time, but now... I haven't heard of such a thing for many years."

"If the order was not issued directly from the working group, I would think it was a joke."

Hearing his words, Zheng Jiuyuan nodded slightly.

"It's all the same. As long as they really do earthquake-related geological work, I don't think anyone can believe the statement about earthquake prediction."

"Earthquakes are a typical chaotic model, and there is no index system that can be directly observed. With our current technology level, even predicting the probability is extremely difficult, let alone accurately predicting the three elements."

"I always thought that the earthquake in Haicheng was purely an accident where a blind cat hit a mouse—and there really wasn't even a single successful case afterwards."

"But this time, it feels like it's for real."

"How to say?"

Zhong Jian asked curiously.

"Have you read the news? We recently signed a heavy-duty helicopter import contract with Russia, and the outside world is guessing what these heavy-duty helicopters are for."

"Some people speculate that there is a big move on the border, and some speculate that it will be deployed to Djibouti on the other side of Africa to engage in armored airborne troops."

"But these people obviously didn't guess the idea. If you combine what we are doing now, it is obvious that these helicopters are for disaster relief."

"This is a large order close to 15 billion yuan, and the investment is frighteningly high."

"If it is not a matter of certainty, the official will not take this risk"

Seeing Zheng Jiuyuan's serious expression, Zhong Jian frowned thoughtfully, and then continued to ask:

"What if I just bought it as a piggyback?"

"I mean, maybe the main use is military, and it can also be used as a backup."

"But looking at this matter, it is indeed possible."

Zheng Jiuyuan took a breath and continued:

"But you have to read the news comprehensively."

"Recently, this is not the only big move the higher-ups have made."

"Over the economic port, the superior has issued several new notices, requiring some enterprises and institutions to do a good job of 'capacity reserve'. What does this mean? It is the work that can be done by two machines, and now the number of machines needs to be increased. to 3."

"Generally speaking, there are only two purposes for issuing such notices."

"Either it is to indirectly stimulate economic growth, or it is to deal with the impact of major events in the future."

"Economic growth, we don't need it - it's growing fast enough."

"As for the big event, in fact, the predictable big event is nothing more than war."

"Do you think we might go to war? Impossible."

"So, it can only be a disaster."

Zhong Jian seemed to have been persuaded by Zheng Jiuyuan, his expression became serious, and then he asked:

"So you mean, this earthquake is really possible?"

"I do not know."

Zheng Jiuyuan shook his head and continued:

"No one can say for sure whether it will happen or not, but from a certain point of view, officials have indeed determined that this earthquake will happen."

"So, what we have to do is to keep a good secret, give full play to our abilities, and actively cooperate."

"You know, if it doesn't happen, it's a good thing, because nobody's going to die."

"If it happened, more than one person could be saved for every minute we spend here"

"Then let's do it quickly."

Zhong Jian immediately stood up and began to assemble the portable drilling instrument quickly.

Two other team members with military background also stepped forward to assist. It didn't take long for the instrument to be assembled, and the two immediately started drilling operations.

As the soil and rock samples that went deep underground were continuously brought out of the ground, Zheng Jiuyuan couldn't help but sighed and said:

"Looking at the environment of this address, the probability of an earthquake is really not small. If it happens, the damage caused will not be small."

"This place itself is located on the thrust nappe structural belt, and there are three major faults nearby, which belong to the stress concentration point of the compression of two plates. The accumulated stress on the nappe structural belt is definitely not small, and it is normal for earthquakes to occur. matter."

"Coupled with the complex terrain and landforms here, the rock structure is not stable, accompanied by water and soil erosion, once an earthquake occurs, a large number of slope instability will definitely occur."

"At that time, once secondary disasters such as intensive aftershocks, dammed lakes, and mudslides occur, the intensity of disaster relief will increase exponentially."

"It's no wonder the government attaches so much importance to it. It's really not a trivial matter."

Hearing his words, Zhong Jian temporarily stopped what he was doing, and the roar of the drill decreased, and he said:
"That has to actually happen. In short, let's hope this is just a miscalculation."

"In fact, the probability of misjudgment is quite high, estimated to be over 99%"

"But overall expectations were too high."

Zheng Jiuyuan interrupted him, Zhong Jian was taken aback for a moment, and then understood what he meant.

100% probability, multiplied by the loss with 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 then again, is the seismic shield really useful? I have never seen any country that uses this method to prevent earthquakes."

"Useful, and very useful."

Zheng Jiuyuan replied without hesitation.

"The reason why you haven't heard of it is because the construction of the seismic 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 a seismic shield structure in advance like we do, it will still have a great effect."

"According to theoretical calculations, after combining the two methods of seismic shield and surface vegetation cloak, the Rayleigh wave of the earthquake can be reduced by at least 70% or more."

"With this level of attenuation, the destructive effect has been greatly reduced."

"Of course, we are mainly talking about face waves here."

"The damage caused by body waves is inevitable anyway, but compared with Rayleigh waves, body waves are much less destructive regardless of whether they are horizontal or vertical."

"We have no way to eliminate the body wave, and 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 seismic shield encloses Yingxiu, it is impossible to block most of the body waves, right?"

"That's why the range is 15 kilometers."

Zheng Jiuyuan explained:

"According to the information from the superior, the focal depth of this earthquake is about 14 kilometers. We center on the surface of the focal point and have a radius of 15 kilometers. We can attenuate the Rayleigh wave as soon as it is formed."

"However, we are only doing preliminary investigations now. Depending on the situation later, the radius of the seismic shield may be extended."

"At that point, the risk will be further reduced."

Zhong Jian nodded heavily, and then said:
"It seems that the superior has considered it very carefully this time."

"Yes, so in terms of execution, we can't make mistakes"

After all, the two threw themselves into the exploration work again.

And in the county town not far from them, there is a peaceful scene
At the same time, near Xigong University, in Wang Jiancheng's laboratory.

Wang Jiancheng stood opposite Chen Nian and Qiao Mai, conveying the so-called instructions from the "superior".

".So, to sum up, the superior asked us to upgrade the mechanical exoskeleton."

"The requirement for the upgrade is to further enhance the power system of the exoskeleton and require a hydraulic weight-lifting module."

"At the same time, optimize the energy of the exoskeleton, using the latest high-density lithium batteries, or other new batteries."

"Under continuous working conditions, the exoskeleton is required to have a battery life of more than 6 hours, and can lift more than two tons of heavy objects through the hydraulic weight-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 area."

"Of course, robustness is also a must, it has to be very durable"

Having said that, Wang Jiancheng paused for a moment, then continued:

"These conditions sound quite difficult, but the rewards given by the superiors are also very rich."

"We can directly use the cooperative department—that is, the mechanical laboratory of North Industries, and other materials are also provided by North Industries."

"As for the personnel, there are more."

"In short, we will give you what you want, as long as you produce results within the specified time."

"How about it, two, think about it?"

Hearing Wang Jiancheng's words, Chen Nian was not moved at all.

The reason is simple, this request was made by him.

The reason for such a requirement is to adapt to the rescue environment in the disaster area.

In his last life, he saw with his own eyes many people digging up the ruins with their own hands until all their fingernails fell off and even their bones were exposed.

He has also seen people propping up huge concrete slabs on their own shoulders, just to bring a glimmer of life to those under them.

This situation makes people helpless and sad. In the corner where large machinery cannot enter, "powerlessness" has become the reality that makes people cry the most.
-
However, things are a little different now.

Mechanical exoskeletons have appeared in advance, and their functionality has been verified.

So why not develop a dedicated exoskeleton on this basis?

It doesn't need too complicated functions, but only needs to do one thing: it can enter the ruins flexibly and lift heavy objects stably.

If these two points are achieved, the dilemma of "terminal rescue" will disappear by more than half
Just as the scene of the exoskeleton rescue flashed involuntarily in Chen Nian's mind, Qiao Mai who was on the side spoke:

"I can participate as a support person, but I can't do it full-time."

"You know, my postgraduate topic has been selected, and I will spend a lot of time preparing for the project. I don't think I can spend too much time on this project."

"That's enough! I mainly hope that you can solve the problem of the hydraulic weight lifting module, which you are familiar with."

Wang Jiancheng replied cheerfully.

In fact, he didn't expect Chen Nian and Chen Nian to devote themselves full-time. After all, this can be said to be his own project, and everyone has other things to do.

"Senior, what about you?"

Hearing Wang Jiancheng's question, Chen Nian shook his head directly, and replied:
"I'm not going to participate. I can't be of much help."

"Then I'll put your name on it, it will be useful in the future."

Wang Jiancheng said without hesitation.

".Fine."

Chen Nian didn't bother to give in too much to him, so he simply complied.

However, seeing the excited expression on Wang Jiancheng's face, he couldn't help asking with some worry:
"Are you confident in this project? I think the conditions are quite harsh, in case it can't be realized"

"It won't be impossible!"

Wang Jiancheng interrupted Chen Nian and explained:

"Senior, don't look at the complicated setting of these conditions, but in the final analysis, if you only look at the underlying logic, the equipment that the official wants to make is actually very clear."

"That is, the disaster relief robot."

"Look, flexibility, high endurance, hydraulic weightlifting."

"These three points have actually limited the application scenarios to death. In addition, the last one requires high stability in extreme environments. I even took AK47 as an example. What they really want is self-evident. bright."

"So, after knowing the purpose, it is very simple to optimize."

"I already have a blueprint in my mind, as long as you give me the laboratory, I can make a prototype in less than a month"

Hearing this, Chen Nian finally felt relieved.

Although Wang Jiancheng is full of all kinds of seemingly unrealistic ideas in his mind, in fact, when it comes to doing things, he is still very reliable.

So, he didn't say any more, just emphasized one sentence:
"Since the purpose can be determined, then remember to design according to the purpose, and don't go astray."

"rest assured!"

Wang Jiancheng nodded solemnly and replied:
"If it was something else, I might still have a play mentality."

"But this thing is going to be used for disaster relief in the future, and I won't make any jokes about it."

"On this point, you can definitely rest assured!"

With Wang Jiancheng's promise, Chen Nian finally felt a little relieved.

After talking about the details of the project, he bid farewell to Wang Jiancheng and left his laboratory with Qiao Mai.

Seeing that it was getting late, Qiao Mai proposed to go out for a meal together. After all, they are about to graduate, so there should be a sense of ceremony.

Chen Nian thought that this was indeed the case, so he walked out of the gate with her, but just after he left the school gate, his cell phone rang.

After answering the phone, Chen Nian smiled apologetically at Qiao Mai, who also let him go understandingly.

However, after he left, Qiu Mai's eyes were full of doubts.

She didn't know what happened to Chen Nian.

Looking at Chen Nian's eyes, there seemed to be an extremely excited expression.
-
I haven't heard of him dating either.

Maybe, someone more important?
Qiao Mai smiled self-deprecatingly, and walked out of the school gate on his own.

But if she knew the content of that call, she would definitely feel that she deserved to lose.

Because, the news that that phone call brought to Chen Nian was:

The experiment of the new electromagnetic gun has been completed, the structure optimization has been completed, and it is ready to board the ship.

　Introduction: Xu Shouyi traveled to the world of all summoners, where summoners can use summoning stones to summon all kinds of creatures and even equipment.

　　Xu Shouyi's summoning talent was average, but he accidentally discovered that he could communicate with other worlds and summon his blind date.

　　The first blind date: Living in the zombie world of the end of the world, a tyrannical and unparalleled human race supernatural being nicknamed Gatling Girl Bodhisattva.

　　The following blind dates: Hate Married Girl, Desperate Housewives, Protoss Empress, Martial Arts Demon Head, Bachi Snow Girl...

　　Seeing so many blind dates, Xu Shouyi expressed that he was not panicked at all.

　　It's okay if you don't have the talent for summoning, I will summon the blind date with my backhand.

　　Unknowingly, he formed an army of blind dates, invincible!
