Please make money.

Alia and Ai Rulin followed them. Boss Huo finally stepped onto the concrete floor and stamped his feet. “Didn’t I ask before? They said it was well maintained and the spillway was unobstructed… But the truth is, we were deceived. Did you bring the blueprints?”

"Of course I bring it." Alia took out the blueprint and spread it on the box next to her. "What's the problem?"

Boss Huo leaned over to take a look and pointed at the downstream of the Xiqiao Reservoir. "The dam of the reservoir is an earth dam with a top height of only 5 meters. It is said to have a capacity of million cubic meters, but due to siltation, the actual capacity should only be around million. There is only one floodgate downstream, and the maximum flow rate per second was designed to be only cubic meters."

Ailia frowned, and Ai Rulin next to her had the same expression. The latter had just brought the engineering team here a while ago and had not yet gone to inquire about the situation.

"What about the spillway? Doesn't it mean that as long as it works properly, there will be no problem?"

"Yes, that's the problem. The spillway itself was a natural gully on the left bank of the river upstream. Later, a slope protection was built to turn it into a spillway. But that was ten years ago. In the past ten years, urban construction has expanded outward, and the overpass of the West Fourth Ring Road has crossed this side. For convenience, many illegal things have been done."

"No one cares?"

"Yes, but urban construction is more important than anything else. They also promised to remove the facilities that block the spillway after the elevated road is built, but now..."

But now, heavy rain has come, and it doesn’t matter whether your bridge is repaired or not.

Alia looked up at the half-finished overpass in the distance, then looked in the direction of the spillway that was out of sight.

"When the water level exceeds 158 during the flood season, we have to release water immediately, but at 5 cubic meters per second, how much can be released?"

"Dig it up?"

“So I said, you came at the right time!”

Three hundred pieces of construction machinery could dismantle an unfinished overpass and throw it into the mine to create a flat ground in one night, let alone dig a ditch.

Ai Rulin was not so optimistic. He shook his head and said, "It's already 155 meters now. It's only a matter of time before the water level reaches 158 meters. If we release water by then, the two-meter reserve will not be enough. But we dare not act rashly. I have been watching it before. The best way is to dig out the left cliff and dig a new flood discharge channel."

This is an officially managed reservoir. They are citizens who are eager to help. They cannot just build things under the guise of official support. They need permission.

But by the time the experts arrive, the water level limit may have exceeded 160.

In that case, the flood will overflow the dam, causing serious erosion or even direct collapse of the dam.

When a reservoir collapsed, the West Fourth Ring Road and two towns all became neighbors of Xiaoyuer.

"What should I do?" Alia looked at her watch: "It's half past two. Fortunately, we came early."

Boss Huo also looked at his watch: "It should be about time, it's coming."

"Who?"

"The official team of Tianhai City." Boss Huo turned around and looked at the huge reservoir that seemed endless in the rain.

"They were directing disaster relief in the city before, and after learning about what happened here, they rushed here. They should be here soon."

Ailia and Ai Rulin looked at each other, and then looked at the back of Boss Huo.

"Xiaoya..."

"Ok?"

"Guess what they asked me just now?"

"What do you want to ask?"

"They asked me how many construction machines they needed. It would be too late to transfer them now. They already have 12 machines."

"Then what did you say?"

"hey-hey……"

……

……

More than ten minutes later, the official team arrived at the troubled Xiqiao Reservoir.

"Mr. Huo! Mr. Huo - thank you so much! You solved my urgent problem!"

"Don't thank me. If you want to thank someone, thank this kid."

Boss Huo brought Ailia out to meet everyone. With Tianhai City being an international metropolis, Ailia is now equivalent to meeting the provincial team.

Ai Xiaobaihua's smile was pure and had a reassuring and gentle beauty, which greatly improved Tianhai City's official favorability and reputation.

Fortunately, everyone knew that this was not the time for small talk. Secretary Hou walked into the rain despite the heavy rain, touched the tall mining machinery, and was filled with emotion.

"Great! Great! I feel more confident now!"

You have to know that before, the entire Tianhai City could only mobilize dozens of manpower at once.

Even though the Xiqiao Reservoir knew that something might happen, they only found eight excavators on standby.

As for the large-scale machinery that could dig through the dam and excavate the floodway, after searching the entire city, only 12 machines were found that could be transported here.

Then a phone call came in, three hundred units!

Although we received a lot of information in the morning about enthusiastic citizens in the city driving large-scale construction machinery to rescue, everyone thought it was an individual behavior.

I didn't expect that the Ai Group had such preparations. They came prepared! Great!

Three hundred organized and dispatched construction machines plus a whole mature engineering team are more valuable than gold at this time!

"The experts' assessment is that at least 100,000 people will have to be evacuated from the West Fourth Ring Road and the two towns downstream."

"Then organize a transfer immediately!" Secretary Hou wiped his face and said, "At a time like this, life safety is more important than anything else! Hurry up!"

Soon, the authorities made the decision to relocate all users on the ground floor and below the second floor in the entire West Fourth Ring Road area and the four main roads in the two towns. The relocation took about two hours.

The transfer work is ongoing, and the investigation and assessment by water conservancy experts have not stopped.

Several hours later, the water conservancy experts waded out of the waist-deep water and said, "No problem! We can dig! Dig on both sides at the same time!"

"The dam is not at risk of collapse for the time being. It is not too late to take action now, and we have sufficient engineering manpower!"

Perhaps because the water was too abundant, the plan proposed by the water conservancy experts was a bit too grand, and four flood diversion channels were dug on both sides.

Under such circumstances, the official team was actually under great pressure to report the risk of dam collapse and evacuate tens of thousands of citizens.

There's obviously nothing wrong, why make such a fuss to scare everyone?

But the official attitude is very firm. Being scolded is a small matter. Life safety is more important than anything else. Moreover, with this amount of rainfall, no one dares to say that there is no risk.

"It seems the rain is getting heavier?"

"Don't worry too much unless there is a flood peak upstream, but there are drainage channels there."

"But my eyelids are moving up and down..."

"Ms. Ai, thank you so much this time! Fortunately, you extended a helping hand in time!"

"No, this is what we should do. We are also in Tianhai and we happen to have these tools. We have no choice but to do it."

"Oh, that doesn't count. Tianhai City will remember your contribution. I know your group. If there's anything you need help with, you can give us your opinions and suggestions. It's our job to do practical things for enthusiastic companies like yours."

"Of course, of course. We just did what any enthusiastic citizen would do."

"Hahaha, what a caring citizen! What a caring citizen!"

"It's not good! It's not good!!"

Along with a burst of panicked shouts, there seemed to be some vague noises coming from the busy construction site.

"The dam upstream has collapsed! The flood peak - the flood peak is coming! The dam on our side has been breached!"

"Can you block it?!"

"Yes! Drive over there!"

"Quick! Call back all the drivers!"

Ai Rulin rushed out almost subconsciously and jumped directly onto a heavy mining truck next to him.

"Push all those containers in first! Hurry!"

Ailia's eyes jumped violently, and she turned around and pushed An Lele: "Take everyone away from here."

"Where are you going, Miss?!"

"If there is a breach, it can be blocked. Didn't you see that Uncle San is already there? I'll go and help."

Among the more than 300 pieces of construction machinery transferred back by the Ai Group, there are a number of large mining trucks, which are now fully loaded with earth and rocks dug out from trenching, just right.

She jumped onto the door of a nearby mining truck, which had its door open. Within seconds the truck rushed away with a low roar.

Car after car rushed forward like a formation of geese. Boss Huo and others were dragged back by An Lele.

"Girl! Girl—your girl—what is she doing! Let her come back!"

Boss Huo was shocked. Is Alia trying to kill herself?

"Miss, it's okay. She's very powerful!" An Lele stuffed Boss Huo into the car.

"You guys retreat first. What's the risk? It's just a matter of driving the stone over. It's just a matter of stepping on the accelerator. You weren't afraid when you were delivering supplies under the naval guns. You were wearing a life jacket."

"How can that be the same! How old are you - hey - come back! Where are you going?!"

"hey-hey……"

248-Ellie What? For Sin Bag 20/20

When Alia rushed onto the levee, a lot of stones had already been thrown into the breach, but it was useless.

She jumped out of the car and looked at the breach in front of her. There seemed to be rushing water on both sides.

“How wide is the breach?”

Next to him was Ai Rulin, who was pale: "Go back! We can't block it - at least forty meters!"

There was a 40-meter-wide gap, with rushing water rushing out. More than ten tons of rocks were thrown in and washed away in an instant.

Even if the previously filled containers were thrown in, they still floated for a few times like light plastic bottles before sinking with difficulty.

"Let the dump truck go up!" Alia grabbed Ai Rulin and said, "Drive straight in! Rush into the water!"

A mining dump truck has a load capacity of more than eight tons and was previously fully loaded with rocks and soil. This thing is more useful than anything else.

And this is not Arya trying to be a hero. With current technology, there are only three ways to breach the dam and block the breach.

One is vertical blocking, which starts from one or both sides of the dam and slowly closes from the outside to the inside.

This is the one Alia has chosen now. After the mining truck is loaded, it rushes directly from both sides, constantly filling the gaps on both sides and closing the gap in the middle.

As for the other two methods of flat blocking and mixed blocking, they are not applicable at all now.

The flat blocking method is very complicated. It requires referring to the axis of the dam and filling it layer by layer from bottom to top. The blocking can be carried out only after the filling material is above the water surface.

Where is the time now? Slow work brings fine results, right? If we have the ability to slowly repair the 40-meter breach, we won't have to stand in the rain.

Mixed plugging is a combination of flat plugging and vertical plugging. According to the actual situation of the breach, the two plugging methods are flexibly adopted for mixed construction.

Ai Rulin gritted his teeth and said, "If we use a bulldozer, it will take time..."

"Why use a bulldozer! And if a bulldozer is used to push a car down, it won't have enough inertia. The car can only block one position and can't reach the middle of the breach!"

Alia turned around and jumped into the car. "Let all the drivers get out. I'll get in! Shift to third gear, turn up to 2,000 rpm, step on the accelerator, and get ready to jump out!"

"What are you crazy about!" Ai Rulin woke up as if from a dream: "Come down! Come down quickly!"

Alia ignored him and the car roared forward. When she saw that there was only one or two meters away from the breach, she jumped out of the car.

The vehicle flashed various lights, and it tilted and fell into the breach. It was instantly swallowed up by the surging water and turned into a turbid yellow mud mark.

But what was visible to the naked eye was that as more than eight tons of rocks, mud and the car itself fell into the breach, the surging water swirled and was blocked to some extent.

"Very good, the test is feasible!" Alia wiped her face and said, "Hurry up! Hurry up! Drive in! The small dump truck can also drive directly in!"

If there is enough preparation time, you can just use manpower to throw stones, or make a string of steel cages, which are much more useful than a car.

But there is no time. The few containers that were hastily made can only serve as steel cages filled with stones, but the number is too small.

At present, the flow rate of the breach is definitely greater than three meters per second. Excavators and other equipment cannot keep up with the impact of the water flow and all the water will be lost.

This situation happened when the Yangtze River embankment in Jiujiang broke, and all previous hard work was wasted.

In the end, they used the most easily found construction scaffolding on site to make fences, which finally blocked the breach of the Yangtze River.

And what fixes the scaffolding fence is not steel wire or metal buckles, but soldiers!

They jumped directly into the breach, and everyone held onto the scaffolding horizontally, using themselves as sand and gravel bags.

Before the scaffolding fences were built, Jiujiang directly sank several thousand-ton coal barges to block the breach.

Later, because the ship was too light and there was no time to carry enough stones, the soldiers simply jumped into the ship to cushion the cargo, and fought against the waves to buy time, so that the dam could be repaired.
