The military-industrial scientific research system of the academic master.

The Xunyang Yangtze River Levee breach sealing project was completed in less than three days, which is a huge encouragement to the flood control work in the entire Yangtze River Basin.

Similar plots also occur along almost all the banks of the Yangtze River, Songhua River and Nen River——

These are also the three river systems most at risk from flooding.

Three days ago, when the breach in Xunyang just appeared, the Jiangling area was also facing the surging sixth wave of floods.

Although the levee there is still standing, springs have been found in many places.

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

Obviously, finding this kind of situation on the embankment means that cracks have appeared on the water surface of the embankment. If it cannot be dealt with immediately, it will affect the safety of the entire embankment.

The Xunyang Embankment breached within a short period of time after the bubble phenomenon was discovered.

There is nothing we can do to eliminate hidden dangers.

But the difficulty is not any lower than sealing the breach.

Since it is impossible to determine the specific location of the breach on the water surface, it is unrealistic to dump a large number of sandbags enough to cover the embankment surface in a short period of time. Therefore, it is generally necessary to find a soldier with good water resistance to dive into the water with sandbags to find the specific spring where the bubble occurred. After the position is determined, fill the blockage accurately.

Needless to say, there are risks involved here.

Just diving with more than 20 kilograms of sandbags is almost impossible for most people.

You know, no place can provide professional diving equipment to so many warriors.

So it almost all relies on physical resistance.

Fortunately, although the Tashan Garrison Hero Regiment became famous for its battle in the northeast, it has been stationed in the south for a long time after the founding of the People's Republic of China. Its sources of troops generally come from the south, especially the coastal areas, where there are many warriors with good water skills.

But even so, the situation is getting increasingly difficult.

At this time, it was learned that the dam had broken in the Xunyang section downstream. For the defense command center, it was undoubtedly the last straw that could affect decision-making.

No, it should be said to be a huge rock.

Whether or not to release the sixth wave of floods has become a question lingering in everyone's mind.

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

However, as the Yangtze River Defense Commander in charge of the overall situation, the amount of information they possess is unmatched by those in Xunyang.

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

In addition to common urgently needed disaster relief equipment such as construction machinery, helicopters and trucks, Ding Gaoheng and Cao Gangchun also focused on two other items.

One is a high-altitude balloon that can carry out signal relay.

Although ionospheric transmission in the VHF band can certainly guarantee communications between Jiangling and Beijing on land, it is obviously impossible for both the affected people and grassroots units to have such professional equipment.

Therefore, when someone reported that the satellite communication phone was out of service a few days ago, the commander-in-chief felt that his heartbeat stopped for a moment.

The information uploading and distributing is not smooth enough, which is terrible for the ever-changing situation.

With the mentality of almost treating a dead horse as a living horse doctor, 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 from the other side does come out of the receiver.

The content of the report is: "A village in Balingshan Town suffered from severe waterlogging. Three families were trapped on the roof before they could evacuate."

In the following period, the reason why the frontline headquarters could still understand the flood control dynamics of Jiangling and even the entire Hubei Province in near real-time under extremely poor communication conditions largely relied on this high-altitude balloon.

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

As the disaster situation in Hubei Province is more serious, most local factories are unable to maintain stable production. Therefore, many of the flood control equipment supplied here are produced in Sichuan and Shaanxi.

Under the urgent situation, the commander-in-chief even directly ordered to mobilize two helicopters of the Army Aviation Force, and took advantage of the light rain to transport a batch of temporarily produced equipment to Jiangling.

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

"Captain Huang, have you tried out the newly arrived equipment?"

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

"We are trying it out now. The effect of the expansion bag is as described in the instructions. After being soaked in water, it will become similar to a sandbag. Our current solution is to put two layers of impermeable plastic bags on the outside. Soldiers can take it with them to find the need. After sealing the location, remove the plastic bag.”

The commander-in-chief nodded.

It seems that in just half an hour, the frontline units have developed new usage that suits them according to local conditions.

Next, it’s time to look at the final effect.

Just a few seconds after Huang Linqun finished speaking, a person emerged from under the water.

"Captain, it works, it works!"

"Give me a few more bags, and I'll go down two more times at most, and I'll be able to completely block it!"

Since one person can carry nearly ten bags before they are soaked, rather complex secondary processing is required before entering the water, and sealing must be ensured. Therefore, the pressure is now on the side of the people staying on the shore. .

"Captain Huang, now that there are so few people who need to go into the water, can we use the diving equipment?"

The commander-in-chief wiped the rain off his head and said.

"We have already sent people to get it. It used to take a platoon of soldiers to block a spring mouth. A few sets of equipment are not enough. But now it is enough for three people to go down, and the equipment support can keep up."

Only twenty minutes later, several soldiers responsible for diving completed all tasks and landed successfully.

Someone quickly brought blankets and hot water.

"Before, even the people in the cooking class and logistics department had to work in the water. Now that the pressure is less, I let them go back and take charge of their own work. Doing good logistics is also a guarantee of combat effectiveness."

Huang Linqun noticed the commander-in-chief's gaze and explained.

The latter walked directly over:

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

Seeing Huang Linqun and another person of high status approaching, the soldiers who were resting under a tent made of raincloth stood up one after another.

The sharp-eyed commander-in-chief will notice that the hands of several people holding the water bottles are shaking slightly.

He didn't speak in the end, just looked for a moment and then turned away.

"What a good warrior..."

The commander-in-chief took off his glasses, wiped them with the corner of his clothes, and said with emotion.

"Yes, our regiment also has a soldier recruited from Qiong Province. He was originally a son of a wealthy family and became a soldier through connections. But before going to the embankment, he handed me a party application form, and then he never went down again. He was a soldier for several days in a row. Tiandu was responsible for the diving operations. Until just now, I was really worried about something going wrong, so I left him on the shore and was responsible for sealing the expansion bags, so that he could continue to go into the water without causing trouble..."

The military is a melting pot, the best place to train people.

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

The commander put his glasses back on, then quickly turned around and left.

After seeing the situation at the scene, he finally strengthened his determination to continue not to release the flood.

Also, the production of new flood control equipment must be expedited!

……

Chang Haonan, who is far away in the capital, naturally has no way or possibility to visit the flood relief site in person, but thanks to the advancement of technology, he can still see many on-site scenes of rescue and disaster relief through TV while leading Sun Huizhong to design the DSI air inlet. .

Naturally, this includes the thrilling work of blocking the Xunyang Embankment.

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

If the content is sensitive, he will be taken over.

This allows the latter to see a lot of content that is not reported on TV news.

Such as the evaluation of "Xi soil" in various places.

Of course there are some suggestions for improvement.

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

"Although there are many highlights in this disaster relief operation, judging from the feedback, there are still many shortcomings, especially at the equipment level."

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

"The satellite phone we imported suddenly failed to find satellite signals and could not be connected at the most critical moment. If it hadn't been for the high-altitude airship jointly developed by you and Zhejiang University, there would have been a big problem in Hubei Province."

"Furthermore, we have had many helicopter pilots report that their self-purchased GPS positioning equipment has been interfered with. Some of them malfunctioned. Although some of them were functional, the position and altitude errors were seriously increased. There was even a crew in Hubei Province who rescued people after rescuing people. Because of the wrong navigation, the plane went astray, and if there were not local people on board who were familiar with the situation, it would have almost hit a mountain."

"Someone is taking advantage of this opportunity to give us eye drops..."
