It took less than three days to complete the Xunyang Yangtze River embankment breach plugging project, which is a great encouragement for the flood control work of the entire Yangtze River basin.

And a similar plot also takes place along almost all the Yangtze River, Songhua River and Nenjiang River-

These are also the three most threatened by flooding.

Three days ago, when the breach on the Xunyang side just appeared, the Jiangling area was also facing the surging sixth wave of flood peaks.

Although the embankment there is still standing, bubbling springs have been found in quite a few places.

That is, under the action of seepage. The fine particles of the soil form pores along the skeleton particles, and the flow rate of water in the pores of the soil increases, causing the fine particles of the soil to be washed away.

Obviously, the discovery of this situation on the levee indicates that there is a crack in the frontal surface of the levee, and if it is not dealt with immediately, it will affect the safety of the entire levee.

The Xunyang embankment burst in a short period of time after the discovery of the bubble spring phenomenon.

If you want to eliminate hidden dangers, it is not impossible.

It's just that the difficulty is not lower than that of plugging the breach.

Since it is impossible to determine the specific location of the breach on the water surface, it is unrealistic to pour a large amount of sandbags down enough to cover the embankment in a short period of time, so it is generally necessary to find soldiers with good water ability to dive into the water with sandbags, find the specific location of the spring, and then accurately fill the block.

Needless to say, there are risks involved.

Diving with 20 kilograms of sandbags alone is almost impossible for most people.

You know, it is impossible anywhere to provide professional diving equipment for so many fighters.

So it's almost all about physical resistance.

Fortunately, although the famous battle of the Tashan Garrison Hero Regiment was in the northeast, it was stationed in the south for a long time after the founding of the People's Republic of China, and the source of soldiers generally came from the south, especially in the coastal areas, and there were many soldiers with good water nature.

But even then, the situation is getting more difficult.

At such a time, it was learned that the Xunyang section of the downstream dam had failed, which was undoubtedly the last straw that could affect the decision-making of the defense command center.

No, it should be said to be a boulder.

Whether or not to leak out the sixth wave of the flood peak has become a question that haunts everyone's mind.

If it is not released, not only will the Gangneung Dam be in great danger, but the flood peak will also affect the downstream areas.

It's just that as the Yangtze River Defense Commander who commands the overall situation, the amount of information they have is incomparable to that of Xunyang.

Before rushing from the capital, the commander-in-chief specially listened to reports from the General Armament Department and the Commission of Science, Technology, and Industry for National Defense.

In addition to the usual equipment needed for disaster relief, such as construction machinery, helicopters and trucks, Ding Gaoheng and Cao Gangchun also focused on two other things.

One is a high-altitude balloon that can be used for signal relay.

Although the ionospheric transmission in the VHF band can certainly ensure communication between Gangneung and Gyeongseong on land, it is obviously impossible for either the affected people or grassroots units to have such professional equipment.

Therefore, when a few days ago, when someone reported that the satellite communication phone had failed, the commander-in-chief felt that his heart had stopped for a moment.

The information upload and distribution is not smooth enough, which is simply fatal for the rapidly changing situation.

With the mentality of almost dead horses as live horse doctors, they activated the frequency band corresponding to this high-altitude signal relay station.

Then, it was connected.

Although the call quality is a little rough, the voice on the other side does come from the earpiece.

The report reads: "A village in Balingshan Township experienced severe waterlogging, and three families were trapped on rooftops before they could evacuate. ”

In the ensuing period, the reason why the front-line general headquarters was still able to understand the flood control dynamics of Jiangling and even the entire Hubei Province in near real time under extremely harsh communication conditions depended to a large extent on this high-altitude balloon.

With this experience, the commander-in-chief couldn't help but have great expectations for another piece of equipment, that is, the modular flood control reinforcement kit named "Siyang".

As the disaster situation in Hubei Province has become more severe, most of the local factories have been unable to maintain stable production, so many of the flood control equipment supplied here is produced in Sichuan and Shaanxi.

Under the urgency of the situation, the commander-in-chief even directly ordered the mobilization of two helicopters of the army aviation unit to transport a batch of improvised equipment to Gangneung while the rain was light.

And he himself then followed the equipment directly to the vicinity of the embankment.

"Commander Huang, have you tried the new equipment?"

After seeing the soaked Huang Linqun, the commander-in-chief's first sentence was straight to the point.

"I'm trying, the effect of that expansion bag is the same as on the manual, after soaking in water, it will immediately become similar to a sandbag, our solution now is to put two layers of impermeable plastic bags on the outside, and the soldiers will take them down to find the location that needs to be blocked, and then open the plastic bag."

The Commander-in-Chief nodded.

It seems that in just half an hour, the front-line units have developed new uses that suit them according to local conditions.

Next, it's time to see the final result.

That is, just a few seconds after Huang Linqun's voice fell, a person came out from below the water.

"Commander, there is an effect, there is an effect!"

"Give me a few more of those bags, and go down two more times at most, and you'll be completely blocked!"

Since the bags before they were absorbed could carry nearly ten per person, but they had to undergo a rather complicated secondary treatment before entering the water and ensure the tightness, the pressure now went to the people who stayed on the shore.

"Captain Huang, now that the number of people who need to go into the water is so small, can you use the diving equipment?"

The commander-in-chief wiped a handful of rain from his head and said.

"It's been taken by people, it took a platoon of soldiers to block a bubble spring mouth before, and a few sets of equipment were not used at all, but now it's enough for three people, and the equipment support can keep up."

Only twenty minutes later, several of the fighters in charge of diving completed all the tasks and landed successfully.

Soon someone brought a blanket and hot water.

"In the past, even the people in the cooking class and the logistics department had to go into the water, but now that the pressure is less, I will let them go back to take charge of their own work, and doing a good job in logistics is also a guarantee of combat effectiveness."

Huang Linqun noticed the commander-in-chief's gaze over there, and took the opportunity to explain.

The latter walked over with direct steps:

"Let's go, let's see the heroes who just came up."

Seeing Huang Linqun and another person whose visual identity was not low, the soldiers who were resting under a shed made of a rain cloth stood up one after another.

The sharp-eyed commander-in-chief will notice that the hands of several people holding the kettle are trembling slightly.

He didn't speak, just looked at it for a moment, then turned away.

"What a warrior......"

The commander-in-chief took off his glasses, wiped them with the corners of his clothes, and said in an emotional tone.

"Yes, our regiment also has a soldier recruited from Qiong Province, who was originally a child of a rich family and a soldier entrusted to him, but he handed me an application to join the party before going up the embankment, and then he never went down, and he was responsible for diving operations for several days in a row. It wasn't until just now, when I was really worried that something was wrong, that I left him on the shore and was responsible for sealing the expansion bags, so that he didn't make a fuss and continued to enter the water......"

The army is a melting pot and the most tempering place.

"Write down the names of outstanding performers, publicize them, and vigorously publicize them!"

The Commander-in-Chief put his glasses back on, then quickly turned to leave.

After seeing the situation at the scene, he finally strengthened his determination to continue to maintain the flood control.

And, the production of new flood control equipment must be urgent!

……

Chang Haonan, who is far away in the capital, naturally has no way and cannot go to the flood control site in person, but thanks to the progress of technology, he can still take Sun Huizhong to work on the DSI air inlet design, and at the same time, he can see a lot of on-site pictures of rescue and disaster relief through TV.

Naturally, it also includes the thrilling plugging work on the Xunyang embankment.

In addition, Cao Gangchun also specially asked the General Office of the General Armament Department to send a copy of the feedback sent to him to Chang Haonan.

If it comes to sensitive content, he will be taken over.

This allowed the latter to see much of what was not covered on TV news.

For example, the evaluation of "Siyang" in various places.

Of course, there are some improvements.

For example, Gangneung hopes to put a waterproof membrane on each expansion bag when it leaves the factory.

"Although there are many bright spots in this disaster relief, there are still many deficiencies from the feedback, especially at the equipment level."

Cao Gangchun took out a cigarette and put it under his nose and sniffed it, then stuffed it back into the cigarette case:

"The satellite phone we imported, at the most critical time, suddenly could not find the satellite signal and could not be connected, if it were not for the high-altitude airship that you and Zhejiang University jointly made, I am afraid that there would be a big problem in Hubei Province."

"In addition, we have a lot of helicopter pilots who have reacted that their self-purchased GPS positioning equipment has been interfered with, some of them are out of order, and some of them can be used, but the position and altitude errors have seriously increased, and even a crew in Hubei Province lost directly because of wrong navigation after rescuing people, if it were not for the local villagers who were familiar with the situation on board, they would almost hit a mountain."

"This is someone who is using this opportunity to give us eye medicine......"
