Military: Last but not least?I was admitted to the best military academy

Chapter 110 Diving

The light rain gradually became heavier, and it turned into a downpour in a short while.

But on the embankment, no one sheltered from the rain.

They all carried sandbags under the torrential rain.

The more it rains, the harder it is to walk.

They need to thicken the embankment a little bit with sandbags so that it is difficult for the flood to break the embankment.

But the mighty power of nature has always been irresistible to human beings.

Lu Feng was carrying sandbags when he suddenly heard someone shouting in the distance: "Fountain! The spring has appeared!"

The sound came from the other side of the embankment.

Lu Feng and the others filled sandbags on the other side of the river.

So none of them knew what was going on, and looked around blankly.

Only those who know about springs become extremely nervous.

On the embankment, Jiang Ying immediately commanded loudly: "Quick! Immediately surround the well where the pipeline exits."

The soldiers immediately moved nervously.

Then, Jiang Ying ordered to the soldiers on the river surface: "Everyone carefully observe the water surface to see where there is a vortex. If you find a vortex, report it immediately no matter how big or small it is!"

The military headlights immediately illuminated the river surface, illuminating the water surface brightly.

The soldiers all watched nervously.

However, it was still raining and the view was not good.And the rain dripped on the faces of the soldiers, making people blind and making it more difficult for everyone to observe.

As for Lu Feng, as a military expert in his previous life, although he didn't know much about water conservancy projects, he had heard a little about them.

Soaking in springs means piping.

It is because the soil layer below the foundation of the embankment is a permeable layer with strong water permeability.

Under the water pressure of the high water level on the river surface, the water seeps from the soil layer under the foundation of the dam and crosses the dam.

Under certain conditions, a natural water pipe will be formed.

This caused river water to emerge from the soil downstream on the other side of the dam.

It's like a spring that spouts water suddenly appeared on the ground.

That is to say, the water surface of the flood does not need to be higher than the dam, and it can also seep out from the underground soil layer.

Once the piping occurs and is not dealt with in time, it may cause the collapse, subsidence, cracks, slope detachment, etc. of the embankment body, and the most serious one will cause the embankment to burst.

Because the piping will become larger and larger with the flow of water, and in severe cases, the foundation of the embankment will lose its load bearing and the entire collapse will occur.

Jiang Ying shouted to surround the well, in fact, to block the water outlet of the pipe.

Prevent piping from expanding.

It is very difficult to block.

Because the underground water pipes are still there.

Therefore, blocking the exit is only a temporary solution, not the root cause.

Only by blocking the entrance of the pipe and preventing water from entering the pipe can the pipe surge be prevented from expanding.

The entrance of piping is at the bottom of the river.

This is why Battalion Commander Jiang asked the soldiers to observe the surface of the river carefully.

Just because of the piping, it is like the drain gate of a swimming pool is opened, and the water will form a tornado-like vortex during the discharge process.

But this vortex is not guaranteed to form.

Only when the drainage velocity is large enough can it be formed.

There will be a vortex, indicating that the piping is relatively large, which means that a great danger will be caused at any time.

In the heavy rain, although the search was difficult, the soldiers did not give up.

He searched the lake with all his heart.

Ten minutes later, a soldier suddenly shouted.

"There, there seems to be a whirlpool there."

Everyone was shocked.

The vortex really appeared.

Hearing this, Lu Feng also hurried over.

That seems to be the location of D area.

When the eyes are eight times the viewing distance, the field of vision is instantly zoomed in.

He saw the vortex clearly.

About the size of a bowl.

On the embankment, Jiang Battalion Commander also ran down the embankment slope to confirm.

After he confirmed it, without further ado, he picked up a bag of sandbags and jumped into the water.

All the soldiers were at a loss.

Only Lu Feng understood that he was going to block the entrance of the pipe.

However, the entrance of the piping is likely to be tens of meters deep at the bottom of the river.

What is the concept of tens of meters?
Ordinary people will feel very uncomfortable diving ten meters without diving equipment.

Professional divers can only dive about 15 meters to 17 meters, which is the limit.

The deeper the water, the greater the water pressure and the greater the pressure on the human lungs.

With Jiang Ying's jump, he never considered whether he could come back safely.

Without any hesitation, he had already picked up the sandbags and jumped into the water before all the soldiers could react.

He did not spare his life.

Because he knows that as long as he blocks the entrance of the pipeline, it is possible to prevent the landslide and break the embankment and save hundreds of thousands of people downstream.

Less than half a minute after Jiang Ying jumped down, a figure ran quickly, and before the soldiers had time to see clearly, he plunged into the water with a splash.

The soldiers were in an uproar!
At this time, the deputy commander on the embankment shouted.

"Who? Who dived?"

He just went to the downstream of the dam to direct the soldiers to surround the well and pipe the outlet.

But suddenly felt flustered, and hurried up the embankment to check.

Then I saw the ripples splashed by someone jumping into the river.

However, he even asked a group of soldiers, but no one could see who was diving.

The deputy conductor felt a strong sense of disobedience, but couldn't tell what it was.

I can't think of a reason after thinking about it.

Knowing that a soldier muttered casually: "Jiang Ying also jumped before."

The deputy commander was shocked all of a sudden, and hurriedly grabbed the soldier and asked, "What did you say? Battalion Commander Jiang jumped down?"

The soldier was startled by his appearance, and tremblingly said: "If I read correctly, he jumped down with a sandbag on his shoulders."

The deputy commander's eyes turned red immediately, and he asked anxiously again: "How long has he been jumping?"

The soldier hesitated and said, "Probably, almost a minute."

The deputy commander felt anxious, turned around and wanted to jump down too.

Then he roared, causing a circle of soldiers around him to pay attention to him.

Seeing his movement, he quickly stretched out his hand to pull it away.

Two of them have jumped down and they haven't come up yet, so how dare they let the third one jump down again.

Death is not sent like this.

They were unable to stop them before, but this time under the watchful eyes of everyone, they failed to let the deputy commander succeed.

After the deputy commander was stopped, he also realized that he had lost his position.

He shouted: "Quick, shine all the lights here!"

"On the shore, quickly ask someone to shine all the lights on this side!"

The ultra-high-power military headlights immediately shone directly on it.

The deputy commander didn't think it was enough, so he called for the military flashlight he was holding.

And before the flashlight was brought over there, there was movement on the water here.

Everyone showed that they saw a lot of bubbles rising.

Then under the strong light, I saw a black shadow floating under the water.

The soldiers suddenly exclaimed.

After a while, black shadows emerged from the water, revealing two heads.

One of them dragged the other to swim to the shore.

The deputy commander shouted: "Pull them up quickly."

The soldiers went into the water one after another and pulled the two ashore.

Of the two, one woke up and the other fell into a coma.

The person who woke up gasped and reminded loudly: "Give him CPR!"

Soldiers hurriedly lifted the man to level ground and began chest compressions.

After a few presses, give artificial respiration.

Repeatedly, after pressing for 1 minute, the unconscious person spewed river water from his mouth, coughing and waking up.

The deputy commander immediately breathed a sigh of relief, and then ordered: "Hurry up, take Jiang Ying up and send him to the hospital."

The unconscious man was none other than Battalion Commander Jiang.

The soldiers immediately carried Jiang Ying up to the embankment with one hand and one foot, and carried Jiang Ying to the embankment, then loaded the car on his back and sent him to the hospital.

It was only then that the deputy commander turned his head and asked the young soldier sitting on the bank panting, "Private, what's your name?"
