Civil Air Defense Project No. 110.

Through the sorting position of the header number, you can tell its importance, and from the importance, you can also see the scale.

Civil air defense projects, as the name suggests, civil air defense projects, usually integrate the protection of personnel and materials during wartime, air defense command, and medical rescue.

As an important defense project, it is also often called the Underground Great Wall.

The capital, as the capital of the new country, is also the heart. In order to ensure the wartime safety of the people, the capital can endure for a long time in the face of aggressive wars.

Since the founding of the People's Republic of China, excavation work on this underground Great Wall has never stopped.

In the past few decades, the birth of the new country was a difficult process of crumbling. From a swaddling baby to now, it has become a giant with a straight back. The wind and rain that our land has experienced are things that many people have not experienced. experienced.

, a photo of a little boy sitting alone in a train station full of ruins, crying loudly, because at that time, there was no perfect civil air defense project for protection.

Facing the "umbrella flowers" of white parachutes falling from the sky, everyone knows that it will be fatal if they fall, but they can only panic and run around for a chance of survival.

It is precisely because we have experienced pain that we have the “medicine” that doctors can prescribe~!

Nowadays, our industrial base has slowly taken off. Although it still lags behind the other side of the ocean, as hundreds of millions of people are determined to tighten their belts, they will eventually catch up or even surpass it.

What is "Yao Yin Zi"? It is the mother of the earth. It has nurtured hundreds of millions of people. When faced with the exploding flames falling from the sky, it has never been stingy in its embrace, taking the people it has nurtured into its own again. Give them a temporary safe place in their arms.

Digging tunnels is our traditional means of fighting aggression. However, under the new situation, tunnels have been transformed into civil air defense projects, and the requirements will only be more in terms of scale and professionalism.

When conditions are difficult, you can bend down and even be able to climb over, then that's fine. Now, you not only have to be able to pass people, but you also have to be able to pass cars. Not just cars, but trucks, and even trains. You have to be able to pass at critical moments. Arrive in time and transport additional supplies to increase the means of resisting risks in the face of threats.

Transportation is only the most basic. There is also water and electricity to ensure people's basic life when they are hiding. In addition, supporting first aid stations, disinfection stations, laboratories, etc. are also indispensable.

Large-scale civil air defense projects, on the basis of the above, will also consider personnel areas and set up special auditoriums, cinemas and other cultural and sports venues to supplement the spiritual food of the people.

Adding up the bits and pieces, plus the excavation work itself, you can imagine how much manpower and money it cost to build such a large underground Great Wall.

This is the case with Civil Air Defense Project No. 110. Different regions have different importance. As can be seen from the code name, its birth took countless people's efforts.

"Zi, buzz buzz~!"

The solid granite can only turn into powder in the face of the harder drill bit. As the light pink powder column of more than half a meter long was stuffed in, the detonator followed closely, and finally there was a long fuse. .

"No. 53 is preparing to detonate, all personnel retreat and take cover~!"

As the piercing warning sounded in the tunnel, shirtless "workers" brought machines with them one after another and hurriedly evacuated. It rotated rapidly, and after a loud noise, it was followed by billowing smoke and dust.

"Go to the water, go to the water, evacuate, evacuate~!"

As the smoke cleared, the disgraced workers went back to observe the situation and prepare to clean up the sand and gravel. They heard a heartbreaking cry that made people feel heartbroken.

The ground where the gunpowder smoke had cleared was not completely dry, only sand remained. A small stream of water had gradually gathered. It started out like a child peeing, but not long after, it turned into an elephant, and finally, it became a stream. A real stream.

Because of the relationship between the water pressure and the water outlet, the water flow that jumps out from the rock cracks is simply a sharp water jet. As long as it is directly in front of it, let alone people, it will hit the opposite wall. , holes were drilled out of the solid stone.

Water leakage accidents are very common in tunnel excavation projects. The underground water veins are very complicated, and there may be cracks, faults, and collapse areas. No one can investigate clearly. After a few decades, there will be nothing to do but the drainage station. Do your homework.

"Can it be blocked? Can it be blocked?"

The construction workers wearing armbands hurriedly stopped the workers who were evacuating urgently, and anxiously asked about the situation inside. The water leakage was also prioritized. If it could be stopped without affecting the progress of the project, that would be the best.

"If we can't stop it, the cracks will expand. Evacuate first. Evacuate here first~!"

Only the observers know what is going on at the blast site. The water jets are splashing inside. Look at the water pressure. Let alone rescuers, if you don't get out, once the crack expands, you may have to stay inside.

There was no time to transfer the machinery and equipment. With the roaring and collapsing sounds inside, the workers didn't even have time to take pickaxe handles, sledgehammers and other tools. They ran out one by one holding their bamboo safety helmets. Outside the tunnel, it is still a tunnel. Only the construction workers know how far it is from the ground. At this time, they can only save their lives first.

Faintly, you can see that the sand and gravel above your head are shaking. You can clearly feel the dust filling the tunnel that was silent just now. This is a precursor to a collapse caused by a water leakage accident.

As he ran desperately, he could see the preliminarily repaired tunnel ahead. A huge iron door was right in front of him, and the rushing water behind him was already chasing him.

"You guys get out quickly, I'll close the door~!"

The safety officer could also hear the sound of water flowing behind him. He glanced back and saw that the turbid muddy water would follow them into the next section of the tunnel they had worked so hard to dig. Seeing that everything would be in vain, he gritted his teeth. No more running.

"I'll stay too, TN. You can close it alone. I believe in your ancestors...!"

Several workers stayed where they were and used all their strength to slowly close the big iron gate. As the valve was tightened round and round, the big iron gate was gradually locked.

The water that had nowhere to vent flowed from the ankles to the knees, from the knees to the thighs, all in the short period of time the valve was locked.

They knew that there would be a glimmer of hope if they ran outside, but if no one closed the iron gate, they might harm their unsuspecting comrades in other tunnels.

Yes, that's right, they are not workers, but people's soldiers. It's just that the hard work in the tunnel has allowed them to temporarily take off their proud military uniforms, but deep down, they can still let their comrades rest assured. It's for them, soldiers.

……

Half an hour later, at the main entrance of the civil air defense project, due to a water leakage accident in the No. 53 tunnel, most personnel received the alarm and evacuated.

"What's going on inside?"

The engineering command personnel in the tunnel, after withdrawing from other tunnels, found the person in charge of the scene. They didn't even have time to wipe the dust off their bodies and asked hurriedly.

"A serious water leakage accident occurred in the No. 53 excavation tunnel. The sealed door leading to the No. 50 main tunnel has been locked. However, the nearby No. 51 and No. 54 still collapsed. Only one team was evacuated... …!”

The person in charge at the scene who learned the specific situation was also mentally exhausted. In a short period of time, his eyes turned red. No need to think about No. 53. Once the sealed door is locked, there will be no life inside, but No. 51 and No. 5 On the 14th, there are still more than a dozen people. The cave collapsed. As long as the water does not escape, people can still be saved.

"Well done, they are great. To save people, call the hospital first and send the injured away first. TN ones, I'll go down and save people~!"

There is no time to be sad for them, and there is no time to remember them. All these can only be temporarily forgotten. The most important thing is to save people first.

"I don't agree. A secondary landslide may occur inside at any time~!"

"I am the project commander. No one knows better than me about Tunnel No. 50. There are reinforced vents, and every one can be rescued~!"

"Comrades, the time has come for us to be tested by the people. Don't abandon us, don't give up, and I won't force you. The only children will stay, and the unmarried ones will stay...!"

As the resolute voice ended, one after another, the disgraced soldiers stood up bravely, picked up the rope and shovel without hesitation, turned around and ran into the tunnel again.

Trucks were pulling seriously injured people towards the hospital, passing by ambulances that were speeding by.

In a short period of time, personnel made repairs on the spot, and the lightly injured were bandaged by medical teams. In the tunnel, stretchers were carried out one after another until the ambulance responsible for transport arrived.

"Doctor, doctor, there are still some inside. No. 51 rescued a few of them. They can't move~!"

"I'm going to save people~!"

In one of the ambulances, a doctor in a white coat jumped out of the white car with great agility, preparing to participate in the rescue of people at the scene. After hearing the greeting, he picked up the box in the car and waved. Run into the tunnel.

In this hectic time, vigilance is at its lowest. Who would check a doctor's ID?

However, after entering the tunnel, the person dressed as a doctor did not rush to save people. Instead, he headed straight towards the empty engineering command office on-site office.

The purpose is to steal the No. 110 civil air defense project and project drawings. (End of chapter)
