They were all reborn and became firefighters again?

Chapter 318 This is Poe!

He was surrounded by leaders, and it was difficult for him to interrupt.

After listening for a long time, and spending some military merit points to obtain information about water, Fang Huai finally got a clue.

This small county is different from where he used to stay. There are only two reservoirs in the entire county. This is the larger one. This reservoir is shared by the two counties.

Beyond that, he heard a word.

Floods and droughts accompany each other.

This is a very strange phenomenon, but it makes sense.

Like last night, the rainfall was too concentrated, which will inevitably lead to insufficient subsequent rainfall. Crops and farmland will not be irrigated by sufficient rain in the right season, which will undoubtedly make this barren area worse.

Once the weather turns dry, the water here will be an important source of water for nearby farmland irrigation and domestic water.

Therefore, the significance of this reservoir is very important. It is not only a problem of floods, but also related to people's livelihood. Everyone is doing their best to protect it.

In his previous life, he had just been dawdling around for more than thirty years. When he was a fire fighter, he had a lot of professional knowledge, but this knowledge about people's livelihood was really his blind spot. Just like before, he didn't even know how to plant seedlings. know.

He knew how much disaster a large reservoir could bring, but he didn't know how significant a reservoir was.

When he arrived, he still didn't understand why the firefighters didn't go to the streets to provide disaster relief, but they all rushed to the reservoir.

In fact, even if more than half of a multi-million-square-meter reservoir collapses, the distance from the town will not have an exaggerated impact on the streets. It will just be that within a few hours, the water will rise a few centimeters higher. It won't be long before it goes down.

He has seen more than 3000 million cubic meters of flood discharge in Tangjiashan. When the water was at its largest, it rose more than [-] meters high, which was nothing.

And there were many reservoirs in Chongqing in the past. He secretly swam in them, and there were seven or eight of them, many of which were larger than this one.

Much bigger.

However, in this small county, a reservoir of several million square meters provides an average daily water supply of 10,000 to [-] square meters, which is related to the livelihood of [-]+ people.

Water, draft, irrigation.

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

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

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

The county has suffered from successive disasters in recent years, fighting against the weather and trying hard to restore farmland production. If the reservoir breaks and loses one of its existing stable water supply channels, it will face another head-on blow besides rocky desertification.

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

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

Cao Yi obviously knew much more about this issue than he did, so even though he was weak, he still decided to give it a try.

After his rebirth, his memory greatly improved, and he could remember most of what he had experienced in his previous life. He boasted that he had extensive knowledge, but he suddenly discovered that there were too many things that he had not seen in his previous life for more than thirty years.

You still have to be humble and learn.

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

What can I do by myself?
Dam, there are enough people.

To pump water, there are machines.

drain…

Yes, they just said that the drainage outlet is always blocked.

"Director Cao, I'll go take a look at the drainage ditch."

After Fang Huai said that, he went directly to the side with more people.

Cao Yi saw his positive look and knew that he wanted to find a way, so he didn't stop him.

...

After asking around, I found the flood outlet.

It is a small old reservoir. The slope is covered with weeds. The outlet is not very pretty. It is more than 20 meters long. The water flow does not look very fast. The outlet is filled with sediment and garbage. Maybe it was here when it was built. The water level is not high, the discharge surface is short and narrow, and the slope is almost at a right angle. Moreover, under the current drainage situation, the excavator cannot work at all to widen the flood discharge surface.

Manual dredging...

It is simply unrealistic. No matter how small the flow of water there is, it is still a flood outlet. Even if it is protected by a rope, it has to be lifted up when approaching the outlet. Is it possible to work in the air?

One person and two people can go down with a hoe and shovel, but they can't clean much. Is it possible to hang dozens of people down?
With so many people, it would be strange if an accident did not happen, and once the desilting is completed, the water flow will be strong and two people will be washed down, which will not be worth the loss.

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

It's difficult, otherwise there are so many People's Liberation Army troops here who dare to block their bodies on the dam, and they would have gone long ago.

Mechanical desilting will not work, manual desilting will not work...

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

"Director Cao, Director Cao! Drive the 13 tons to the vicinity of the flood outlet!"

"What are you going to do?"

"Water gun desilting!"

……

15 minute later.

The road to the side of the water outlet was surrounded by a group of soldiers from the Second Squadron.

"Oh no, brother, you are a genius." Cao Yi swallowed.

Fang Huai smiled and pointed at the turbulent but not huge water flow below: "Well, my method is much better than your stupid pumping over there."

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

Fang Huai smiled and said, "Just tie two safety ropes to me."

Zhang Yang immediately raised his hand: "Director Cao, I'll go down and be his second player!"

Fang Huai waved his hand: "What second officer do you want? Lay a water hose along the slope, and you can just pull the hose on top! My second officer should be on top! Pay attention to my instructions and cooperate with the intercom! "

At this time, Hao Chengbin put his hands behind his back, glanced down at his head, clicked his tongue, and said:

"Old Cao, what you say is too unconscionable. Is it a little dangerous? It's very dangerous!

Also laying water strips along the slope?Fang Huai, is your name appropriate?This fucking wall is obviously a wall!This is called laying the hose vertically!There is no such thing as you! "

Fang Huai chuckled at this time:
"Monitor, remember, 90 point 0 degrees is a wall, and 89 point 9 degrees is a slope."...

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

Dredging is considered a municipal and civil construction project. Among the leaders here, those who know about fire protection have never done civil construction. They know a little bit about civil construction but don't know anything about fire protection.

Moreover, high-pressure water gun desilting is not common, and there are many conditions. After flushing, it has to be pumped away with a very long pipe, which is very troublesome. A lot of people are thinking about mechanical excavation. Regarding this drain outlet, everyone The possibility of bringing down a large number of excavators was demonstrated. Firefighter Li Zhi also cooperated, but no one thought of this method.

Fang Huai had worked in the information field in an engineering company, otherwise he wouldn't know how to use CAD.

Although I don’t know much about engineering, I have heard a bit about it.

So when I thought of firefighting equipment just now, I was suddenly inspired.

When everyone heard the plan of the Second Special Service Squadron, they all felt as if the Tianling Gai had been opened.

Damn, they even thought about setting off cannons, but they didn’t think about the water pressure!

Water to water, why direct contact.

Lao Cao felt relieved again.

When in doubt, ask Fang Huai!What a fucking genius!

"call…"

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

Damn it.

I'm flying.

However, the rope behind his back immediately restricted his flight.

"Slow down, slow down!" Hao Chengbin shouted while pulling the rope: "My gloves are torn! Why are you rushing so fast?!"

As he said that, he twisted around and wrapped the rope around his waist again, fearing that he wouldn't be able to pull it.

The few in front were protecting Fang Huai and the hose, and their hands were a little tighter.

Fang Huai yelled: "Holy shit, I can't stop, squad leader!"

At this howl, the people above couldn't help laughing.

Merit 1.

"What the hell..." Hao Chengbin looked at the circle of leaders and cursed a little softer: "Didn't you drag me so hard just now and say this is a slope?"

There was no movement down there.

Fang Huai could no longer hear the shouting above, and his ears were filled with the sound of gurgling water.

The water looks small from a distance, but up close, the water is really big.

This hole is dozens of centimeters high and has been completely opened. It looks very big up close, but it is really not worthy of the weight of this reservoir.

Just here, there are still some stubborn silts, which keep coming in one after another. There are also some large pieces of garbage stuck in the openings. Some branches and sticks are stuck on the thick walls, diverting and blocking the water. The way to the water.

People really can't get down.

Standing on the opening, he already felt like he was about to fall at any time. There was almost no support under his feet. If he was washed away by the water that occasionally carried sand, gravel and mud, he probably wouldn't be able to do anything.

This dilapidated dam will inevitably have problems like this again if we don't make great efforts to repair and reconstruct it this time.

Thinking that this place relies on such a dam to maintain water safety makes me feel sad.

That grandpa, grandma, and those ordinary people are suffering really concretely.

In the current country, with a rural population of [-] million, there are still many poor people.

Fang Huai stood firm, then took out the walkie-talkie and shouted: "Water! Increase the flow slowly, use the protective rope of the water belt, pull it steady!"

"The water is here! I gave 0.6 pressure first! Pay attention to safety!"

One pressure is not standard atmospheric pressure, but MPa, which is about nine standard atmospheric pressures.

The water outlet pressure is 1.6 MPa. Even if it is a medium pressure, according to the standard, more than two people are required to hold the gun.

The high pressure is 3 to 4 MPa, and more people have to be added.

The water is accelerated downward by gravity, with a pressure of 0.6. When it reaches his hand, it is at least a pressure of water.

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

The water hose above is actually hung quite stably, so everyone is very careful.

Soon, the exhaust sound of "Kukuku" came.

The water is coming.

Fang Huai tested the hose and made sure it was sharing enough pressure, and decisively picked up the gun.

"sieve!……"

A strong stream of water rushed to the slightly sloping wall below. The gun was about to shoot upwards, but Fang Huai pressed it down hard and hit the horizontal outlet where the water rushed out.

"My protective rope! Put two centimeters!"

Fang Huai pressed the call button on the walkie-talkie and yelled through his clothes.

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

The water in my hand is stronger than the water from the flood outlet.

Raising his hand, the water suddenly poured into a place of mud. The mud was scattered, and then washed down by the water. The entrance of the cave suddenly became clearer, and the stones became new.

But, there is still mud inside.

Fang Huai continued to flush for a long time, but the stubborn silt never completely dispersed, but just peeled off layer by layer.

"Damn it."

Fang Huai got a little angry and pressed the intercom again:

"Pressure! Pressure!"
