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

When the dozen expansion bags thrown by Wang Hong became as big as sandbags in a short period of time, and finally sank to the bottom of the river, everyone around them who was watching all this was shocked.

Then he quickly threw the expansion bag in his hand into the water.

100 in total.

Piling up in the river, it has even become a line of defense that is beginning to take shape.

Of course, in terms of the entire ulcer area, the effect of these 100 expansion bags is not worth mentioning.

But this was only what less than ten of them achieved in a few minutes.

It didn't even consume much energy.

This is the power of technology.

"Captain, this thing... is simply amazing!"

The regiment chief of staff who was following Wang Hong slapped his thigh and smiled from ear to ear, revealing two rows of white teeth on his face that was already covered with dirt:

"I'll take people with me right now and put all the 10,000 expansion bags in this batch!"

"Wait a moment!"

Wang Hong called the chief of staff from behind:

"Remember to arrange for each company to take turns to rest. I think some soldiers are almost reaching their limit. If they continue to hold on, there may be problems."

As soldiers, they are not afraid of hardship or fatigue.

But flesh and blood has its limits after all.

Each person can only carry one bag of sandbags weighing 20-25 kilograms at most at a time, and even warriors with excellent physical fitness will become weak and exhausted after several consecutive trips, not to mention that almost everyone has been doing this for two days. I didn't sleep a wink for two nights.

There are many who suffer minor injuries and cannot leave the line of fire, and are even so tired that they vomit blood and faint.

As for those with worn out hands and worn-out fingernails, there are countless others.

And this thing in front of them can undoubtedly greatly reduce their work intensity.

It’s not just the difference that everyone can relax a little bit.

More importantly, after the efficiency is improved by an order of magnitude, there is no need to tie everyone to the levee.

It also means that after two days of continuous work, the commanders and fighters of the three regiments responsible for blocking the Xunyang Embankment can finally take turns to rest.

At this time, abundant physical strength is fighting power.

Many martyrs who sacrificed their lives in flood fighting and rescue operations fell down due to exhaustion or were washed away by floods.

"Yes!"

The chief of staff saluted Wang Hong.

"In addition, let the comrades in the cooking class use the existing conditions to try to get some hot meals, even hot water, so that the comrades can recover."

After assigning tasks to his staff board, Wang Hong himself did not rest, but once again took people to the material distribution center next to the dam.

He still remembered that along with those flood-proof expansion bags, there were a bunch of "unremarkable" steel plate beams.

He didn't pay much attention to it before because it was too heavy, but now...

Since the expansion bag is so easy to use, the steel plate beam used with it may not bring any surprises.

Wang Hong felt that the fatigue he had accumulated over the past two days was completely gone.

They moved the first set of bulk steel plate beam components as quickly as possible.

Then under the guidance of the comrade from the Zhejiang Provincial Science and Industry Bureau, it took about fifteen minutes to assemble them together.

The originally ordinary steel structural members formed a slightly strange cage-like structure after being spliced ​​together.

According to the instructions for use, just put a dozen expansion bags into different positions of the steel plate beam, and then throw them into the water in a specific direction.

The entire assembled structure is not light and requires four or five people to lift it with all their strength.

But fortunately, only the last step requires moving it as a whole, before it was all separated.

"one two Three!"

Several people worked together to throw this strange-shaped object into the water as required.

According to their past experience, even metal products of this weight will roll or shift under the impact of water flow after being thrown in.

It had to be fixed to the river bed below by manpower.

This is why even though the length of the breach has been controlled, a considerable number of soldiers still have to be left soaked in the water——

Otherwise, the previously fixed steel bars and wooden piles will easily be disrupted again.

This time, however, things were a little different.

The roaring flood seemed to have been relieved of its force, only causing the steel plate beam to shake a few times at the beginning.

But as the expansion bags inside absorb water and fill the voids, the entire structure becomes rock solid.

"It seems... that it can have a better effect than wooden piles, steel bars and gravel packages?"

This time, Wang Hong and others almost discovered a whole new world.

"There is such useful equipment..."

Almost everyone can see that the combination of flood control expansion bags and detachable steel plate girders can directly reduce the risk and difficulty of flood fighting and disaster relief by several orders of magnitude.

Even local flood control departments, which are less organized and less professional, can still bear a considerable part of the dangers that in the past had to be handled by the People's Liberation Army.

After all, the military's first priority is fighting, and it is impossible to prepare for disaster relief at all times, so most of the time it is impossible to be the first to arrive at the scene.

Just like the situation with the Xunyang Levee this time, if the Xunyang defense manager who responded first had these things on hand when he discovered the hidden danger of the dam breach, he could at least delay it for a long time, or prevent the breach from continuing when it first appeared. expansion.

With the help of two new types of equipment, the second step of the task of blocking the Xunyang Embankment was successfully completed in the evening of that day.

The engineers who were already on standby quickly used the prepared bags of clay, anti-seepage cloth and quick-drying cement to reinforce the temporary embankment structure that took tens of thousands of soldiers two days to build.

At this point, the breach sealing project is fully completed!

The on-site commander was standing next to the newly repaired breach, watching all this with tears in his eyes.

As long as he turned his head slightly, he could see the lights in Xunyang City in the distance.

Although there was some impact there, because the breach was repaired in a timely manner, it did not cause too serious losses.

At the same time, the soldiers he brought from the Jinling Military Region were all safe and sound!

Bring back as much as you bring out.

This is the goal the commander-in-chief set for himself before leading the team.

However, he also knew how difficult it was to avoid any losses in the face of a natural disaster of this level.

So he had never mentioned it to anyone before.

But now it's really done.

"Well done...you are all well done...I can't find such good warriors anywhere, capable of fighting and enduring hardships!"

Standing in front of the three main regiment leaders, the commander-in-chief's tone was choked with sobs.

"Deputy Commander Dong, this time we were able to successfully complete the breach sealing task within 60 hours. In addition to the hard work of the soldiers, it was also inseparable from the two batches of comrades from the Zhejiang Provincial Bureau of Science and Industry who sent us at the most critical moment. Supplies.”

Of course Wang Hong was very excited to be praised by the opponent, but after thinking about it, he felt that he still couldn't be greedy for credit and had to explain the effects of the two key equipment:

"I think our experience should be promoted, preferably by other comrades who are also involved in disaster relief."

The commander-in-chief nodded after calming down his emotions, but in a clear tone:

"I know, in the afternoon, I have noticed that your gagging efficiency has increased nearly ten times. This is definitely not something that can be achieved by working harder, so I went to consult the comrade from the Science and Industry Bureau. "

"He said that this is a production task assigned to them directly from the Commission of Science, Technology and Industry for National Defense, and it is available all over the country. After it is built, it will be transported to the disaster-stricken areas in need nearby, so I think other places should cooperate with us. Same, I’ve already used the two types of equipment you mentioned.”

Having said this, the commander-in-chief took out an expansion bag that had not been thrown into the water from the side, unfolded it in front of him and looked at it carefully.

"It's really unbelievable. It's hard to imagine that such a thin bag can become about the same size and weight as a sandbag once it's wet with water..."

"China has always been a country prone to serious floods. The people who invented these two things owe a great deal of merit to us!"
