At the beginning of the fire to save people, I was broadcast live as a firefighter

In the live broadcast room, the audience's eyes were red when they saw this scene.

"I didn't expect to see such a touching scene in a peaceful age"

"Heroes, these are our heroes!"

"I just read the analysis of some big guys, and the collapse may be as high as 40.00%!"

"Why do so many people go when it's so dangerous?"

"Without so many people, there is no way to carry out rescue!"

"That's right, there are 352 trapped people inside!"

"I used to always want to be a firefighter, but now I'm really scared."

"I'm just the opposite. I wanted to be a clerk, but I've already applied for this year's firefighter exam!"

"Life is alive, something to do, something not to do, I also applied for the firefighter exam."

·······

Li Xiao followed the team slowly into the tunnel, while the members of the second group slowly walked out of the tunnel from inside.

The two sides passed by, and the eyes of the two groups were a little inexplicable.

One side is away from danger and moving towards safety.

One side is far away from safety and towards danger.

Mo Xingwan walked to Li Xiao's side, and asked nervously:

"Brother Li, do you think our rescue below will go well?"

Li Xiao smiled wryly:

"The danger is definitely there, but it is not as great as imagined."

"You are new, and you have never experienced many things."

"When you wait for the rescue, you try to maintain your physical strength to deal with emergencies."

"Don't panic when encountering things, and don't rush forward as soon as your brain is hot, understand?"

"This... is not good?"

Mo Xingwan was a little hesitant, although Li Xiao's words were cryptic.

But the meaning is actually very obvious, that is to try to make him wise and safe.

Li Xiao put his arm around Mo Xingwan's shoulder, and put his ear to his mouth.

"You and Liu Qiang are both newcomers. Liu Qiang is better. After all, he is a soldier who has changed jobs, and his physical fitness is far stronger than that of ordinary people."

"But you are a college student who studied veterinary medicine. I'm afraid you can't even memorize the regulations in the rescue code."

"In the face of such a major disaster, you just need to help others and not hold them back."

"Leave the other things to us old people."

As he spoke, he showed a confident smile and patted his heart.

"But, Brother Li, you're just..."

Li Xiao smiled contemptuously:

"People are different. Did you get third-class personal merit after a recruit who has only been in the job for a month or two?"

Mo Xingwan was forced by Li Xiao's fresh and refined pretense, and was stopped by Chenggong.

However, after thinking about it carefully, he really couldn't compare himself with himself who was able to walk like flying with a 300-jin load on his body.

Seeing Mo Xingwan bowed his head and said nothing, Li Xiao patted him on the back

"Don't worry, even if something goes wrong, we can still hide under the construction vehicle."

"It's a bit dangerous at most, but it's not a big problem to rest assured."

"understand!"

Zhang Wenxin watched the two walk more and more slowly, and couldn't help turning around to remind him:

"Hurry up and talk nonsense!"

"coming!"

····

Soon the team of the first group finally arrived and went deep into the tunnel depth of more than 400 meters.

The task was quickly assigned, and all members of Li Xiao's third team were responsible for installing the support poles.

Hearing the task, Li Xiao couldn't help shaking his head.

Compared with the task of installing support poles, he would rather dig up the collapse.

After all, his physical recovery is much faster than others.

And his digging speed is half faster than that of ordinary people.

It's a pity that the above order could not be changed at all, so he had no choice but to go to the left side of the engineering vehicle with his teammates.

The metal support rod is as thick as a thigh, and each section is 3 meters long. There are two sections in total, which add up to only 6 meters.

These metal support rods are so heavy that your family tried to lift them by themselves before, but it was very difficult.

For normal adult men, two people need to use tools at the same time to fix the 6-meter support pole.

Then in addition, find someone to be responsible for installing it on the fixed platform.

Li Xiao didn't try to be brave either. Although he could lift the metal pole by himself, he was very reluctant.

Instead of wasting energy in vain, it is better to save enough physical strength to deal with emergencies.

It is not the first time that everyone has been arranged to install support poles, so the speed is also quite fast.

Except for Li Xiao who has been responsible for holding up the support pole, the other two took turns to install it.

After all, the physical effort required for installation is relatively small.

In this way, alternate rotation of jobs, you can take a break properly.

The erected support rods are installed.

There will be follow-up engineering personnel to cover the steel sky on the support poles.

And the engineers will inject makc (instantaneous colloidal foam) on the steel sky.

This colloidal foam will produce a violent chemical reaction immediately after it comes into contact with air.

The volume will rapidly expand to more than ten times its original volume, and the originally compact tissue will also become a large and small honeycomb structure.

makc is very extensible and expandable, it will quickly occupy all the free space.

After a violent reaction, the chemical reaction tends to level off quickly.

And it hardens rapidly in a short period of time, its hardness is stronger than ordinary military hardened plastic.

Of course, it is still not enough to compare with ordinary steel.

However, as a buffer between the steel sky and the top of the tunnel, it is already considered the best way.

At least the tunnel is really going to collapse completely, and it can be used as a buffer for the first line of defense for rescuers, delaying for a certain period of time.

Li Xiao looked up at the layers of protection above his head, and the tension in his heart was indeed relaxed.

There are three layers of protection in total. As long as luck is not too bad, most people here should be fine.

The progress of the project was advancing rapidly, and not only clods and debris were transported out by the temporarily modified Wuling Hongguang.

After all, there are only half lanes on both sides left in the tunnel.

Ordinary transport vehicles can't pass at all, and the transport capacity of motorcycle tricycles is too low.

There is only Wuling Hongguang, this kind of boxy car.

With a little modification, it's a very nice van.

It can freely enter and exit the tunnel, and the horsepower is strong enough, and the carrying capacity is large enough.

Every time one meter is advanced, the radio of the engineering vehicle will sound a reminder.

[The current excavation progress is 432 meters: there is still 1.75 meters away from the inside of the tunnel]

[Warning, everyone raises the alert level. 】

[Sonar detection and computer stabilization system issued an early warning at the same time. 】

[The stressed structure of the tunnel is likely to be affected. 】

Hearing the reminder, Li Xiao sighed softly, the last thing she didn't want to happen still came.

Since the above can issue such a warning, the problem must be serious.

······

outside the tunnel.

A group of researchers watched with ashen faces, the excavation results simulated based on the latest sonar detection and field data.

A total of 100 simulation results are displayed on the screen.

Out of 100 simulation results, only 7 simulation results are green.

The other results are all orange or even red, orange means very dangerous, and red means extremely dangerous.
