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

Captain Huang's guess was correct. This kind of matter, which was related to the safety of dozens of millions of people, naturally could not be decided by his mere statement from the captain.

But even so, the determination he and other commanders and fighters involved in disaster relief showed had an impact.

At noon the next day, after a whole morning of discussions, the flood control directorate finally formally issued the instruction "No flood diversion will be carried out until the water level rises to 45.3 meters."

But just in case, the transfer of people in the flood diversion area still cannot be stopped.

With such an instruction, tens of thousands of PLA commanders, militiamen, and cadres and masses involved in rescue operations on the entire Jiangling Embankment were all mobilized to prepare for the upcoming sixth wave of floods!

……

Also at a critical juncture is Xunyang further downstream.

Due to special terrain factors, this city located next to Poyang Lake has borne the brunt of previous Yangtze River floods.

Although the local rainfall is not heavy, when the upper and middle reaches of the main stream and tributaries flood one after another, and begin to interact and overlap, the risk of flooding is actually more serious than in areas with heavy rainfall in the upper reaches.

After the decision not to divert floodwaters from Jiangling was made, the pressure of the entire Yangtze River Basin gathered here in a short period of time.

There is no flood discharge area designed in advance, so there is no other choice but to resist.

At the same time, because there is no flood discharge area, there is no place to focus on in the entire Xunyang section of the Yangtze River embankment.

This is definitely not a good thing——

Anyone who has taken the exam knows that if there are no key points, it means it is all about the key points.

The Xunyang section of the dyke was not expected to withstand such a large flood. As the previous rounds of flood peaks came one after another, it was still unable to fully withstand the increasingly high water levels.

The tens of thousands of rescue troops looked quite large, but if they were to be spread out evenly on the embankment for hundreds of kilometers like spreading beans, I'm afraid they wouldn't be able to hold on even if there was a problem.

Therefore, we can only concentrate on staying at the garrison not far away and wait for orders.

And since the stratosphere above Gan Province does not meet the required meteorological conditions, and Zhejiang University does not have a second set of relay communication equipment on hand, the information transmission situation here is much worse than in the Jiangling area of ​​Hubei Province.

Fortunately, the local weather was okay, so helicopters from the Army Aviation Force continued to take off, firstly to monitor the situation, and secondly, to be ready to respond to possible communication interruptions.

"Report, there is a collapse between gates 4 and 5 of the embankment!"

In the local defense frontline headquarters, an anxious voice suddenly sounded.

The most worrying thing still happened.

"The current breach width is 60 meters, but there is a tendency to expand to both sides."

Liao Xinmin, the local head of the local defense bureau, is naturally far inferior to Niu Maosheng of the national defense bureau, but his determination at critical moments is not bad at all:

"Explain the situation to the People's Liberation Army troops and request reinforcements. The rest of you, follow me up the embankment!"

The breach at the scene was like the gaping mouth of an evil dragon, with torrential water pouring down into Xunyang City.

And there, there are 450 million people who have nowhere to move.

The 60-meter-wide breach itself would not cause the situation to get out of control, but as the saying goes, a thousand-mile embankment is destroyed by an ant nest. If such a breach cannot be controlled in a short time, it may even trigger the collapse of the entire embankment.

This hole must be blocked.

The specific method of blocking will have to be decided by experts from the water conservancy department.

But no matter what method is used, the first step must be to reduce the flow rate and flow rate.

Otherwise, any building materials and construction equipment will not be able to operate normally in the surging river water.

"Have you deployed according to the emergency plan?"

Liao Xinmin asked the on-site staff next to him.

"We had already deployed it when we discovered the bubble phenomenon, but the flood level in our plan was so far behind the current situation that it was a drop in the bucket."

The latter's body and face were almost completely covered with mud and water, and his tone was equally anxious:

"Just now, shipowners from near Poyang Lake rushed over spontaneously and scuttled eight inland river coal ships with a total of 8 tons near the breach. It had a slight effect, but the current was too fast, especially the bottom of the ship was still It can pass through a large amount of water, causing the location of the sunken ship to continue to change. If we can't continue to fill in new blocking items, I'm afraid it won't be long before it will be washed away!"

The cadres and masses participating in the rescue operation on the shore are throwing in all the gravel, rubble and coal they can collect.

But even a sunken ship with tens of thousands of tons cannot guarantee complete stability, let alone these small things, which disappear without a trace almost as soon as they are thrown into the water.

Just when everyone was almost helpless, a shout came from not far behind.

"The People's Liberation Army is here, the People's Liberation Army is here!"

Liao Xinmin turned around suddenly and saw a convoy of hundreds of trucks on the distant road, like a long winding queue, heading towards the embankment.

With the arrival of the People's Liberation Army, there is hope.

"Quickly, prepare the relevant information and the current situation of the breach, and do your best to cooperate with the comrades in the army in disaster relief!"

The first person to lead the team was Wang Hong, the commander of the 1nd Regiment of the 2st Division of the Jinling Military Region.

After listening to a brief report, he went to the breach to check the situation in person.

"We have tried wrecks, gravel, and sandbags, but they all failed to hold and were quickly washed away."

Liao Xinmin wiped the sweat or river water on his face and said to Wang Hong, who was looking around to observe.

"Normally, in this case, blocking the mouth alone is not enough. You need to drive wooden piles and steel bars into the river bed to form a cage-like structure, and then throw gravel bags and sandbags inside."

Before setting off, he had already consulted with senior superiors with relevant experience, so he had already made preparations in this regard.

"But how can you push things into such a large amount of water?"

Liao Xinmin was dumbfounded for a moment after hearing this answer.

If you want to construct in water, you need to rely on blocking materials to reduce the flow rate. And to reduce the flow rate, you need to drive wooden piles and steel bars into the water first?

"Leave it to us."

After Wang Hong finished speaking, he asked for a wrist-thick rope from the staff behind him, tied it around his waist, and then took the loudspeaker used for shouting from Liao Xinmin.

"All cadres above the company level, come out!"

Soon, the few hundred selected commandos tied themselves into several strings with ropes, and the people who stayed on the shore held on to the other end of the ropes.

Immediately afterwards, Wang Hong took off the hat on his head and jumped into the river first.

Under the obstruction of several human walls, the turbulent water finally slowed down slightly.

Others who came up with reinforcements began to throw sandbags into the middle of the human wall.

Although most of it will still be washed away, at least it has begun to have some effect.

It is impossible for trucks transporting supplies to drive directly onto the embankment, so the last section of the road can only be completed entirely by manpower.
