Apocalypse Rebirth: 3000 million won at the beginning

Chapter 673 Drainage system problem! [Wan Gengqiu Monthly Pass Request Subscription]

2 month 17 day.

There are still two days before the rain.

Big camphor tree base.

The morning sun comes out very early.

The sun is very strong these days, and the temperature rises rapidly during the day.

During the hottest time of the day, it can reach eighteen or ninety degrees.

And at night, it will return to only two or three degrees.

On the concrete floor of the inner and outer cities, the rice is still placed on it and exposed to the sun.

Some people took wooden spikes and raked over the rice to get some of the rice out.

After being exposed to the sun yesterday afternoon and air-dried overnight, there are basically no water spots on the concrete floor.

If there are a few more sunny days, the grain can be dried.

In the inner city.

Li Yu is discussing with Xu Zhen about the core drain.

"How is the drainage system upgraded now?" Li Yu looked at Xu Zhen and asked.

Xu Zhen pointed to the inner and outer cities and said: "In the past two days, I have added water pumps to the places where water is easy to accumulate, so that the drainage of accumulated water can be accelerated.

In addition, around the warehouses and residential areas, the height of the open space is lowered, which can effectively accommodate the accumulated water and protect the surrounding buildings.If the previous situation reappears later, there will be no problem.

Now you only need to make some adjustments to the water outlet, expand the water outlet, and dredge the water channel, and there will be no problem. "

Li Yu looked at the deep drain and said, "What are you going to do?"

Xu Zhen thought for a while and said, "I went to see it yesterday. The iron railing of the drainage outlet outside the base had some sediment, leaves, stones and other things deposited on it, which blocked the drainage outlet over time. It must be opened!"

Li Yu frowned and said: "Open the railing. Although it is impossible for zombies to climb up the cliff now, what if the water level below the cliff rises? During the dry season, I don't think that place is safe if it is not blocked.

In short, no matter what, there must be an iron railing as a protection. "

Xu Zhen was a little helpless. The drainage outlet of the camphor tree base was on the cliff, and the top of the cliff was 79 meters high from the ground.

The water outlet they built is at a height of 72 meters.

The snow has melted in the past few days, and the water level under the cliff has risen to nearly 20 meters, forming a small lake.

Below the cliff is a depression, which is more than 40 meters shorter than the nearby forest, but at such a high position, if the water level under the cliff can reach such a high level, the front door of the big camphor tree base will probably be flooded to two Three meters high.

The big camphor tree bases are not at the same altitude. The side near the cliff is shorter, and the side near the gate is higher.

The altitude difference between the highest position and the shortest can reach 7 meters.

It is precisely for this reason that the outfall in the base is chosen on the side of the cliff, which can save construction costs according to local conditions.

Hearing that Li Yu was so determined, Xu Zhen really wanted to say that unless there was a terrible flood that was rare in a thousand years, it was absolutely impossible that the other side of the cliff would be submerged to such a high height.

But he dared not.

Li Yu has already talked to him twice, and he has also told Li Yu about the possibility. Li Yu clearly stated that he knew it, but he still insisted.

Xu Zhen could only frown and think hard.

Li Yu was not in a hurry, and quietly watched him think of a way.

He didn't know how high he would be flooded after the heavy rain in a few days, but he knew that he had to do his best to do all the protection, and the more he did, the better.

Even if it didn't submerge because of the relatively high terrain of the camphor tree base afterwards, what if?
He dare not gamble!

Li Yu stayed here all the time, staring at Xu Zhen to figure out a way.

Under such terrifying pressure, Xu Zhen had a flash of inspiration.

Got it!

"I have an idea, Mr. Li. According to your needs, I think we can bury a hidden line to control the railing of the water outlet on the other side of the cliff, use waterproof and heat-insulated line materials underground, and use steel pipes on the surface of the line. Material protection, which prevents pinch compression.

Then, at the position of the drain, we can use waterproof material to make a switch and connect it to the base through a line, so that we can realize the opening and closing of the iron fence in the base.

In addition, we can even install some cameras next to the drain, so that we can see the drain at any time. If there is sediment and leaves clogged, we will open the railing and close it after it is cleared! "

Xu Zhen breathed a sigh of relief, and hurriedly finished the flash of light in her mind just now, for fear that she would forget it later.

Beside the two, when Lao Lu heard this idea, he thought for a while and asked, "As far as I know, there are tens or hundreds of meters from the wall of the base to the edge of the cliff, and under the wall, The foundations are fully sealed with concrete and poured to a depth of more than ten meters. If you want to lead a line there, then if you don't go through the drain.

Either you walk on the ground, you have to break through a wall five or six meters wide, and of course the same goes underground.I feel that construction is not a very simple matter. "

Li Yu thought for a while, and said, "There is no need to open another hole, just run the line directly from the drain, make sure it is stable, and walk on the roof of the drain hole. Xu Zhen, can this be done?"

Xu Zhen looked at the mouth of the well with a diameter of more than two meters, looked at the flowing water inside, and after thinking for a few seconds, said: "No problem. Mr. Li, as long as the waterproof material and the gate that controls the iron railing can be fixed, all of these will be fine." question."

"Okay!" Li Yu said with satisfaction.

Then let Li Hang and Ding Jiu come over.

Ding Jiu had already worked as a contractor, so he knew a lot of building materials, and naturally knew how to make them and whether they could be made.

After hearing Li Yu's needs, Ding Jiu nodded slightly and said: "I have done it before. I took over a wonderful project before, which was to install some gorgeous lights at the bottom of the swimming pool. His pool has water all year round, and the lights installed below , has never been broken. It can be done, but I need someone to make the control system for opening and closing the door."

Li Hang himself studied mechanical and electrical maintenance in college, so he was naturally involved in this area.

He opened his mouth and said, "Okay, bro, I'll ask He Bing and Zhou Ran to work on this system later, it's not a big problem."

Seeing that the three of them solved the problem while chatting, Li Yu felt slightly relaxed.

Then he said to the three people: "Okay, then you start to act now, Xiaohang, you should go and fix the iron fence and the control system now."

Li Hang asked: "Do you want to modify the original iron fence?"

Li Yu remembered the iron fence that he made before. It has been used for two years, and he didn't think so much when he built the base. Now it is a little rusty.

So he said: "Redo, my request is that it is waterproof and not easy to rust, and the sturdiness should be higher. The stability should be stronger, otherwise we pressed the button to open it in the base, but the iron fence didn't move at all, which would be troublesome!"

Li Hang said seriously: "Okay, when will it be used?"

Li Yu glanced at Xu Zhen and said, "The sooner the better, tonight at the latest."

"So fast?" Li Hang said in surprise.

He didn't understand why he was in such a hurry to do this.

Li Yu naturally would not explain to him that there will be heavy rain in the future, the dam will be submerged, and the flood will rush over.

So he explained: "This time the long-term blizzard caused waterlogging after the snow melted. Although there was no loss, it showed a very serious problem.

If there is a problem, we must solve it immediately without delay! "

In this way, it is also in line with Li Yu's vigorous and resolute style and personality.

After calculating the time, Li Hang said, "It's a bit difficult. After all, it's not an iron railing. We have to fix the wiring and waterproof and heat insulation. The materials are available, but there is not enough manpower. Only the three of us will definitely not be able to do it. We need more people. "

Li Yu thought for a while, thinking about which manpower would be more suitable.

At this time, Ding Jiu said: "Mr. Li, Lao Zhou was a mechanic before. When he was building a greenhouse last time, I felt that he was very professional."

When Ding Jiu said this, Li Yu immediately remembered Uncle Qin and the others from the lathe factory.

So he said: "Yes, Lao Zhou, and let Uncle Qin and the others come over to help you."

There are more than 30 people in Lao Qin's group, all of whom have transferred from the military. They used to work in a state-owned lathe factory, so there should be no problem doing this.

Li Hang said quickly: "It doesn't take so many people, huh? It's okay to come, and the speed is faster. If they all come to help, it can be done in three hours, at most three hours."

Li Yu said with relief: "OK, I'll take another photo later, tell them about the situation here, and start working quickly."

"it is good."

After solving the problem of the iron railing control system and the wiring, Li Yu said to Xu Zhen: "Now? There is no problem?"

Xu Zhen saw that Li Yu was so forceful that he asked people to solve the problem, so she nodded naturally and said, "It's okay."

"Okay, then let's go and remove the iron railing now, and then clean up the mud, sand and leaves inside." Li Yu said.

Lao Lu quickly said: "President Li, don't go in, just let Lao Xu and me go."

Li Yu didn't refuse either, and let Xu Zhen enter the inner city. In addition to his previous contributions, let him be responsible for the drainage problem. He must be the first to go.

You can't always be at the forefront of everything.

So he said, "Okay, let's act now."

When Xu Zhen and Lao Lu heard the words, they immediately changed their clothes, took tools and a flashlight, and tied ropes around their bodies, and slowly went down to the drain.

The drainage outlets in the base will all converge into this square well, and there are underground drains leading to various places below.

It was about seven or eight meters deep from the ground, and iron frames were set up on the walls of the well for them to climb down.

The current snow water has basically been excreted, so the water in the well is very shallow now, and they can go down without wearing oxygen cylinders.

The reason why they tied a rope to them was because there was a cliff when they went out from the drain, and if the iron railings were opened and their feet slipped and they fell, they would be dead.

Xu Zhen stepped on the water, and the water level was so shallow that it barely passed his ankles.

After he went down inside, he immediately turned on the overhead lights. Under the lights, he could see some moss growing on the walls.

tread--

Lao Lu also came down and stood at the bottom.

They looked at the several waterway openings next to them. These waterway openings were all drained from the base, and they were about 1 meter higher than where they stepped on.

With this setting, the height difference can be used to allow the water in the base to drain outside under the action of gravity.

"We're here!" Lao Lu shouted towards Li Yu and others above.

The well is deep and the sound echoes.

Lao Lu and Xu Zhen were in the well, and their ears were shaking.

"Okay, be careful." Li Yu said to them.

Then watched Lao Lu and the two enter the drain leading to the outside of the base.

This drain is not very high, only two meters in diameter.

But enough for them to stand upright and walk.

From here, they went directly outside the base.

From here, it was about a hundred meters away from the cliff, and the two of them walked forward slowly with the lights on.

Sudden.

Lao Lu, who was walking in front, kicked something, he stopped quickly, took out a long knife from behind, and took a step back.

Then he picked it up with a long knife.

slam-la-

A worn piece of jeans, crushed underneath by sediment deposits.

"How could there be jeans, why would someone throw jeans into the sewer..." Lao Lu said helplessly.

Seeing this scene, Xu Zhen also said a little speechlessly: "If everything is thrown into the sewer, it will definitely be blocked!"

"Talk to Mr. Li." Lao Lu said.

Then he took out the walkie-talkie and talked to Li Yu about it.

When Li Yu heard the news, he was slightly taken aback.

I was a little angry in my heart, who the hell threw it!
Make up your mind, after the drainage system is done, you must talk to everyone in the inner and outer cities to emphasize this matter.

"Okay, I see, what's the situation inside you?" Li Yu asked while holding the walkie-talkie.

As Lao Lu was walking, he saw a protruding thing in front of him. He opened it and saw that it was a soda can. Moving forward, there were all kinds of rags, plastic bags, and a lot of garbage.

"This sewer is almost turning into a garbage dump!" Lao Lu said.

"Uh..." Li Yu was silent, absolutely this matter must be raised to a higher level.

Don't throw rubbish down the drain!Once someone does this again, they must be severely punished!
I was also very happy in my heart. Fortunately, I asked them to go down to check this time. Otherwise, when the heavy rain and flood came later, the drainage problem would cause huge troubles to the base.

Xu Zhen's complexion was not very good either. The last time I upgraded the drainage system in the base, I didn't expect there to be so many hidden dangers.

So he took out the walkie-talkie and said to Li Yu: "Mr. Li, I think there is one more thing to do, which is to set up a garbage cleaning system on the other side of the well and block it with iron bars. If there is garbage."

Xu Zhen said a lot, and what she said were those that depended on the drainage system of urban governance.

Including open and culverts, rainwater and sewage diversion, etc.

Li Yu pondered for a while, and said to him: "What you said can be done. The most urgent thing now is to solve the problem at the drain first."

Xu Zhen just gave up.

Lao Lu continued to walk forward.

Soon, he saw a bright light ahead.

Ten meters ahead is the water outlet of the cliff.

bar-

Lao Lu didn't know what he stepped on and slipped.

Whoops!

Lao Lu slipped and stood up.

Looking at the position just now, there is a round shell, bigger than a washbasin.

Lao Lu immediately picked it up with the long knife in his hand, but he didn't move it.

Ok?
What the hell is it?
Lao Lu shone the flashlight on the object, and then.

A turtle's head was exposed.

"Hey! So it's you! Why are you here?" Lao Lu knew the turtle.

When fishing in the lake, a big turtle was found, and everyone in the base knew about it.

Li Yu even put the turtle in the cave.

Then when Blizzard, I didn't see it for a while.

At the beginning, the people in the base searched for it for a long time, but they couldn't find it, but now they found it in the sewer.

Turtles are not mammals and cannot be infected with zombie viruses.

So Lao Lu kicked it with his feet, and said with a smile: "Old guy, I will carry you back later. You are also hard enough to survive such a cold day, you are a real cow!"

Xu Zhen looked at the turtle and was also amazed.

The two continued walking.

Soon, they reached the edge of the cliff.

At the mouth of the cliff, on the iron railings, a lot of garbage and sand were deposited.

These are all blocked by railings.

"I'll take a photo." Xu Zhen said, motioning for Lao Lu to back off.

Lao Lu took a few steps back slightly to make room for Xu Zhen.

Xu Zhen took out her mobile phone, took a few photos of the iron railing, thought about it, and recorded a few more videos.

Since the side of the railing is connected to the outside, the luminosity is very bright and the illumination is very clear.

After Xu Zhen finished filming, she took out the walkie-talkie and said to Li Yu: "Mr. Li, we have arrived. Will the iron railing be removed immediately? If necessary, we can pull the rope from above, and I will tie him up. , you pull it up. You will definitely not be able to pass through the sewer."

After Li Yu heard it, he immediately replied: "Okay, keep it, you two wait for us."

Then he said to Ding Jiu, Li Tie and the people who were following Lao Lu, "Let's go to the cliff through the back door now, and drive a truck there to pull things."

"Okay, Mr. Li." One of them said.

"Oh, by the way, Tiezi, go to the warehouse and get three cameras, and put some surveillance cameras at the water outlet over there. We didn't put them up before." Li Yu remembered and said to Li Tie.

Li Tie nodded and said, "Okay brother, then you go over first, and we will come over later."

After finishing speaking, he took the two of them and went to find Li Yuan.

If you want to open a warehouse, you have to find Li Yuan.

Li Yu also told Li Yuan to bring them some cameras.

After explaining all this, Li Yu took Lao Xie and others out in the pickup truck from behind.

Whenever he wants to go out, Li Yu has to wear a bulletproof vest, even if it's just outside the fence.

With a gun on his back, Li Yu sat in the co-pilot of the pickup truck.

Go out the back door.

Yang Tianlong in the duty room at the back door saw Li Yu and asked about it.

After the pickup truck exited through the back door, it turned a corner and drove another 400 meters before coming to the wall in the direction of the cliff.

In this direction, a duty room is also set.

The scenery in this duty room has always been relatively good.

Seeing Li Yu and the others go out, Song Qi and Monk Xueer in the duty room towards the cliff greeted each other after seeing them.
