Diving

Diving

The light rain gradually becomes bigger, and it will become a heavy rain after a while.

But on the dam, no one hid the rain.

They were all under heavy rain, carrying sandbags.

The more rainy, the more you can't go.

They need to thicken the embankment with a sandbag, so that the flood is difficult to break down the dam.

But the power of nature has always been difficult for humans to resist.

Lu Feng was moving a sandbag, and suddenly he heard someone shouting in the distance: "Soak spring! Soak spring appears!"

The sound came from the other side of the dam.

Lufeng, they filled the sand bag on the side of the river.

So they didn't know what happened, and looked around.

Only those who know the spring spring are extremely nervous.

On the dam, Jiang Ying immediately commanded: "Quick! Immediately, the exit position of the tube surround the well."

The soldiers immediately moved nervously.

Later, Jiang Ying ordered the soldiers of the Jiangshui surface: "Everyone observes the water carefully and sees where there is a vortex. Discover the vortex.

Military headlights immediately take care of the river surface, and the water surface is bright.

The soldiers observed nervously.

However, it was still raining at this time, and the vision was not good. And the rain dropped the soldiers' faces, making people unable to open their eyes, making everyone observe more difficult.

As a military expert in Lu Feng's previous life, although he didn't know much about water conservancy projects, he also heard a little.

Spring is a tube.

It is because the soil layer below the foundation of the dam is a water -permeable layer with strong water seepage.

Under the water pressure at the high water level of the river, the soil layer of the water penetrated from the soil layer under the dam, and passed the dam.

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

As a result, the river water emerged from the dirt on the other side of the dam.

Just like the sprinkler of water spray suddenly appeared on the ground.

In other words, the water surface of the flood does not need to be higher than the dam, and it can also penetrate from the underground soil layer.

Once the tube is not treated in a timely manner, it may cause the embankment to collapse, stuck, cracks, and slope, etc., the most serious one will cause the embankment.

Because the pioneer will become more and more, the foundation will cause the foundation of the dam to lose load, and the entire collapse will be collapsed.

Jiang Ying's siege well is actually to block the outlet of the pipe.

Prevent the tube surge.

It is difficult to block.

Because the pipes of underground permeability are still there.

Therefore, the export is just to treat the standard.

Only by blocking the entrance of the pipe and not allowing water into the pipe, can the pipe prevent the tube from expanding.

The entrance to Guan Yong is at the bottom of the river.

This is why the captain Jiang Ying asked the soldiers to carefully observe the Jiang surface.

Because the tube rushes, just like the drainage outlet of the swimming pool opened, the water will form a tornado swirling during the discharge process.

But this vortex is not necessarily formed.

The drainage speed is large enough to form.

A vortex will appear, indicating that the pipeline pipeline is already relatively large, which means that it will cause great danger at any time.

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

Search the lake completely.

Ten minutes later, a soldier suddenly shouted.

"There, there seems to be a vortex."

Everyone's mind is a shock.

The vortex really appeared.

Lu Feng heard the words and ran over quickly.

There seems to be the position of area D over there.

When the eyes are eight times the distance, the vision is instantly closer.

He saw the vortex.

About the size of the bowl.

On the dam, the head of Jiangying also ran down the slope to confirm.

After he confirmed, he didn't say a word, and he jumped into the water when he picked up a bag of sandbags.

The soldiers were at a loss.

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

However, the entrance of Guan Yong is likely to be at the bottom of the river at the bottom of tens of meters.

What is the concept of tens of meters?

When ordinary people do not bring diving equipment, they will feel very uncomfortable for ten meters to dive.

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

The deeper the water, the greater the water pressure, and the stronger the pressure on the lungs of people.

This jump in Jiangying has never considered whether he can return safely.

He didn't hesitate. When a group of soldiers reacted, he had already picked up a sandbag and jumped into the water.

He didn't regret his life.

Because he knows that as long as the pipe is blocked, it may prevent the landslide from losing the embankment and save hundreds of thousands of people downstream.

Less than half a minute of Jiangying jumped down, and a figure came quickly. When the soldiers had not had time to see clearly, they pushed into the water.

The soldiers were uproar!

At this time, the deputy commander on the dam came from the shout.

"Who? Who dived?"

He just went to the lower reaches of the dam to command the soldiers to surround the well.

But suddenly I felt panicked, and quickly went to the dam to check it.

Then I saw a ripple splattered in the river.

However, he even asked a soldier, and no one saw who was diving.

The deputy commander felt a strong sense of conflict, but couldn't tell what.

I can't think of a reason for Si Lie.

Knowing that a soldier murmured casually: "Jiangying also jumped before."

The deputy commander shocked his whole body, and hurriedly held the soldier and asked: "What are you talking about? Jiang Yingchang jumped down?"

The soldier was frightened by his appearance, and said, "If you don't read it correctly, he jumped down with a sandbag."

The deputy commander turned red immediately and asked again, "How long have he jumped?"

The soldier hesitated: "About a minute." It's almost a minute. "

The deputy commander was in a hurry, and he turned to jump when he turned.

Then his roar caused a circle of soldiers around him to follow him.

Seeing his movement, he quickly reached out and pulled it away.

The two jumping down hasn't come up yet, how dare to let the third one jump down again.

Delivery is not sent like this.

In the past, they couldn't stop it. In the eyes of the public, the deputy commander did not succeed.

After the deputy command was stopped, he also realized that he lost his square inch.
