There are leaders all around, and he is not easy to intervene.

After listening to it for a long time, plus spending a little military merit to obtain relevant information about water, Fang Huai finally heard a clue.

This small county town is not like the place where he used to stay, there are only two reservoirs in the entire county, and this is still the big one, and this reservoir is shared by the two counties.

In addition to this, he heard a word.

Floods and droughts are accompanied.

It's a very strange phenomenon, but it's very reasonable.

Like last night, the rainfall is too concentrated, which will inevitably lead to insufficient rainfall in the future, and the crops and farmlands, in the right season, will not be irrigated with sufficient rain, which will undoubtedly make this barren area worse.

Once the weather turns dry, the water here is an important source of water for irrigation and domestic use in nearby farmland.

Therefore, the significance of this reservoir is very important, not only about flooding, but also about people's livelihood, and everyone is doing their best to protect it.

In his previous life, he was just a mess for more than 30 years, and when he was in firefighting, he had a lot of professional knowledge, but these people's livelihood knowledge was really his blind spot, just like before, he didn't even know the seedlings of the tree.

He knows how big a reservoir can bring disaster, but he doesn't know how much significance a reservoir has.

When he came, he still didn't understand why the fire department didn't rescue the disaster on the street, and all rushed to the reservoir.

A reservoir of several million square meters, in fact, even if more than half of it collapses, the distance from the town will not cause too exaggerated impact on the street, it is nothing more than a few hours of water, a few centimeters higher, or it will not be long before it will go down.

He has seen more than 30 million square meters of flood discharge in Tangjia Mountain, and when the water is the largest, it rises more than 20 meters high, which is really nothing.

And the reservoir, in the past, in Chongqing, there were many of them, and there were seven or eight of them that he had secretly swam, and many of them were bigger than this.

Much bigger.

However, in this small county, a reservoir of several million cubic meters and an average daily water supply of 40,000 or 50,000 cubic meters are related to the livelihood of more than 100,000 people.

Use water, draft, irrigation.

The per capita water consumption is a little more than one person per day.

Here, there is a considerable part of it, and there are some that come from another reservoir, and there are rivers, and groundwater.

Moreover, once the reservoir collapses, the irrigation canals dug for more than ten kilometers over the years, as well as some pipe networks and water purification systems that rely on water supply, will also be abandoned for a long time.

If the dam bursts and one of the existing stable water supply channels is lost, the county will face another head-on blow to the rocky desertification.

Listening to the serious words of the leaders around him, he found that he really underestimated the importance of this place.

Fang Huai couldn't help but feel a little guilty.

Cao Yi obviously knows much more about this issue than him, so even if he is weak, he still decides to fight.

After he was reborn, his memory improved greatly, and he could remember most of the insights in his previous life, and he boasted of having extensive knowledge, but he suddenly found that there were still too many things that he had not seen in his previous life for more than thirty years.

You have to be humble to learn.

Fang Huai realized the seriousness of the problem, and his thinking was running rapidly.

What can I do?

There are enough people.

Pumping, there are machines.

Drain...

Yes, just now they said that the drain is always blocked.

"Instruction Cao, I'll go to the drainage ditch and have a look."

Fang Huai said, and went directly to the crowded side.

Cao Yi looked at his positive appearance and knew that he had to find a way, so he didn't stop him.

…

After inquiring back and forth, I found the flood outlet.

A small old reservoir, the slope is overgrown with weeds, the flood outlet is not too good-looking, the length of more than 20 meters, the water flow does not look turbulent, the discharge port is crowded with sediment garbage, perhaps the water level here is not high when it is built, the discharge surface is low and narrow, the slope surface is almost at right angles, and now in the case of drainage, the excavator can not go to work at all, widen the flood discharge surface.

Manual dredging......

It's not realistic at all, no matter how small the flowing water in that place is, it is also a flood outlet in the end, even if there is a rope to protect it, close to the water outlet, it has to be beaten up, is it difficult to operate in the air?

If you have two people and two people, you can't clean up much with a hoe and shovel, so is it possible to hang dozens of people down?

With so many people, it is no wonder that there are no accidents, and once the dredging is completed, the water flow is large, and the gains outweigh the losses.

Fang Huai frowned, looking at the "slope" that was almost at an angle of 80 degrees, and kept thinking of various possible plans.

It's difficult, otherwise so many PLA people here who dare to block their bodies on the dam would have gone long ago.

Mechanical dredging can't be, manual dredging can't...

Fang Huai's eyes suddenly lit up, and he picked up the walkie-talkie and shouted:

"Cao guide, Cao guide! Drive 13 tons to the vicinity of the floodport! ”

"What are you going to do?"

"Water cannon dredging!"

……

15 minutes later.

The road on the side of the spill was surrounded by a bunch of fighters of the second squadron.

"I'm rubbing, brother, you're a genius." Cao Yi swallowed.

Fang Huai smiled and pointed to the turbulent but not grand water flow below: "How about it, my method is much better than your stupid pumping over there." ”

Cao Yi nodded: "Well, it's just a little dangerous." ”

Fang Huai smiled: "Tie two safety ropes to me." ”

Zhang Yang immediately raised his hand: "Coach Cao, I'll go down and be the second member for him!" ”

Fang Huai waved his hand: "What do you want the second member?" Lay a hose along the slope and pull the hose on it! My number two, it should be on it! Pay attention to my commands, the walkie-talkie works well! ”

At this time, Hao Chengbin put his hands behind his back, looked down with his head, sighed, and said:

"Lao Cao, you're too unconscionable to speak, this is a bit dangerous? is very dangerous!

Also laying hoses along the slopes? Fang Huai, is your name appropriate? It's a fucking wall! It's called laying a hose vertically! There's no such thing as you! ”

Fang Huai smiled at this time:

"Squad leader, you remember, 90 points 0 degrees is the wall, 89 points 9 degrees, it is the slope."

……

Above the wall, many leaders soon came, not only the leaders of the government, but even the captain of the fire brigade Li was a little dumbfounded.

Dredging is a municipal and civil engineering project, and the leaders of the circle here, who know about fire protection, have not done civil engineering, and those who know a little about civil engineering, do not know fire protection.

Moreover, high-pressure water gun dredging is not common, and the conditions are quite many, after flushing with a very long pipe to pump away, very troublesome, a large group of people, the idea of net around the mechanical excavation, about this outlet, we have demonstrated the possibility of a large number of excavators down, the fire Li branch is also mainly cooperative, no one even thought of this way.

Fang Huai has worked in an engineering company for the data sector, or he would not have used CAD.

I don't know much about engineering, but I've heard that there are still a few things.

So when I thought of firefighting equipment just now, inspiration struck.

When everyone heard the plan of the Second Special Service Squadron, they all had a feeling that the Heavenly Spirit Cover had been opened.

Damn, they even thought of firing guns, but they didn't even think of water pressure!

Water for water, why bother with direct contact.

Lao Cao was relieved again.

If you don't decide something, ask Fang Huai! What a genius!

"Whew..."

Fang Huai rushed down the "slope" with a water gun, and his ears were full of the sound of the wind.

Hang Weiya.

Lao Tzu flew.

However, the rope behind him immediately restricted his flight journey.

"Slow down, slow down!" Hao Chengbin pulled the rope on it and shouted: "The gloves are all broken for me!" What are you doing so fast?! ”

As he spoke, he turned around and wrapped the rope around his waist again, for fear that he would not be able to pull it.

The first few protected Fang Huai and the hose together, and their hands were also a little tighter.

Fang Huai yelled: "Damn, I can't stop it, squad leader!" ”

With this howl, the people above collectively couldn't hold back their laughter.

Merit 1.

"Are you special..."Hao Chengbin looked at the leaders in a circle and scolded a little quieter: "Didn't you drag it just now, saying that this is a slope?" ”

There's no movement down there.

Fang Huai couldn't hear the shouting from above, and his ears were full of bubbling water.

From a distance, the water looks small, but up close, it is really, really big.

This opening, dozens of centimeters high, has been completely opened, and it looks very large up close, but it really does not match the weight of this reservoir.

That's it, there are still some stubborn silt, lumps of mud, constantly pouring in, and some large garbage stuck in the mouth, stuck on the thick wall by some branches, wooden sticks, etc., to drain the water and block the way of the water.

People really can't go down.

Standing on top of the opening, he already felt like he was going to fall at any moment, and there was almost no support under his feet, and if he was washed by the water that carried the sand and soil from time to time, he probably couldn't do anything.

If this dilapidated dam is not repaired and renovated this time, it is inevitable that such problems will occur.

The thought that this place actually relies on such a dam to maintain water safety makes my heart sour.

That old grandfather, old grandmother, those ordinary people, the suffering is really specific.

At present, the country has a rural population of more than 700 million, but in the end, there are still many poor people.

Fang Huai stood firm, then took out the walkie-talkie and said loudly: "Out of the water!" The flow rate is slowly increased, and the hose is protected by the rope, and it is a little more stable! ”

"The water is coming! Gave 0.6 pressure first! Stay safe! ”

One pressure, not standard atmosphere, but megapascals, about nine standard atmospheres.

The outlet pressure is 1.6 megapascals, even if it is medium pressure, according to the standard, it takes more than two people to hold a gun.

High voltage 3 to 4 megapascals, you have to add people.

There is also a gravitational acceleration of this water facing downwards, 0.6 pressure, and in his hand, at least a pressure of water.

Fang Huai pressed the water gun hose against the wall, trying to provide a little friction for the wall.

The hose on it is actually quite stable, and everyone is very careful.

Soon, the sound of exhaust gas came from "Kukuku".

The water is coming.

Fang Huai tested the hose for a moment, made sure that enough pressure was shared on it, and decisively picked up the gun.

"Bang! ……”

A strong stream of water rushed to the slightly sloping wall below, and the gun was about to rush into the sky, but Fang Huai pressed down fiercely and hit the horizontal water outlet that rushed out of the water.

"My protective rope! Put two centimeters! ”

Fang Huai yelled at the walkie-talkie call button through his clothes.

The top relaxed slightly, and Fang Huai immediately lowered his body and saw the whole picture of the cave entrance.

The water in the hand is stronger than the water in the floodport.

Raising his hand, the water was the first to pour down on a piece of silt, and the mud scattered in all directions, and then it was washed down by the current, and the hole was clearer, and the stones became new.

But, there's still mud in there.

Fang Huai continued to rush for a long time, and the stubborn silt was never completely dispersed, but only peeled off layer by layer.

"it."

Fang Huai was a little angry, and pressed and held the walkie-talkie again:

"Pressurize! Pressure! ”
