Apocalypse Rebirth: 3000 million won at the beginning

The rising sun shines on the rolling flood.

Tens of thousands of zombies in the flood rose and fell with the waves.

In the buffer city, tens of thousands of workers were dismantling scaffolding and clearing items from the walls.

Thousands of members of the Civil Armed Forces Department took the ultraviolet lamps down from the city wall, and the electrical wires were wrapped into circles and put back on the truck along with the ultraviolet lamps.

Synchronize.

A large number of trucks loaded the sandbags for filling the wall that had been prepared long ago and transported them to the side of the buffer city wall.

Plan B as they call it.

In fact, it is similar to the method used by the Northwest Base to fill the embankment with sandbags.

This is the only effective method to prevent floods in a short period of time.

And it is also the simplest.

However, the soil in the northwest is mainly sandy, and digging sand to make sandbags is extremely effective for flood prevention.

Sandbags are often used in flood prevention.

but.

In the oil city, the main soil is mostly acidic yellow-brown soil.

Earthbags are not as effective as sandbags in preventing floods.

the first.

Low flow resistance: The flow resistance of bagged soil is weak and is only suitable for occasions with small water flow.

second.

Poor waterproofing: The sealing of bags filled with soil is not as good as other cofferdam materials, so it is difficult to make it completely waterproof.

Generally speaking, sandbags and earthbags also differ in their usage scenarios and uses.

Sandbags are often used in flood control, embankment and other projects to prevent water erosion due to their good waterproof properties.

Earthbags are more commonly used for soil conservation, temporary soil piling and other operations.

In scenarios where water needs to be dealt with, such as areas prone to flooding, the use of sandbags is more common.

Plan B for the Oil City is actually to adapt to local conditions.

Steel sheet piles are welded at intervals on the wall. Steel plates are welded on the outermost side to face the impact of floods, and the back is blocked by partitions.

In the gaps between the partitions, use bags of earth and stones or bags of earth and sand to fill the space in the middle and compact the walls.

This will consume sand and steel bars, which were originally used to build concrete walls.

There is no other way because I do this.

They didn't have enough sand to make enough sandbags to protect against floods.

This is the only way to do this.

The reason why they waited until now to implement Plan B is because they need to use the materials originally used to build the concrete wall, and they had previously thought of not using them as much as possible.

At this moment, there is no other way.

Plan B was prepared two days ago, so they moved quickly after it started.

The scaffolding was quickly removed and the bags of earth and rocks were transported by vehicles.

After the items on the wall were cleared, the welders carried the steel plates up and welded them on the wall.

Buffer city ground.

Ding Jiu sat in an armored vehicle and patrolled around the city.

"Old Jie, have all the relevant arrangements been made?"

"It has been arranged." Xie Changshan replied.

He always felt weird when he answered this question.

Maybe it’s because he used to be the person in charge here in Oil City, and he often talks to others like this.

But now that Ding Jiu, the chief engineer of the Dazhangshu base, is here, he has to listen to Chief Engineer Ding.

Naturally, it feels a bit strange.

When they reached the vicinity of the South Gate, Ding Jiu got out of the car and walked towards the wall with Xie Changshan.

This kind of tamping and building dams is the simplest project for professional engineers like them. However, mobilizing tens of thousands of people to build dams and deploying personnel is a heavy task.

The sun gradually rose higher and the temperature outside also rose.

The flood water level is increasing at a faster rate, and the sound of electric welding can be heard throughout the buffer city wall.

Bag after bag of earth and rocks were transported to the wall to fill the gaps between the steel plates.

Xie Changshan looked at the steel sheet piles and said to Ding Jiu:

"Boss Ding, we can also use machinery to remove these steel plates at the back, and we can use them later."

"Well, sand and gravel are actually fine. We will need to use a filter to process them when the time comes." Ding Jiu replied.

"Although there will be some damage, it's not a big deal."

While the two were chatting, Ding Jiu suddenly saw ten helicopters flying from the south.

The helicopter was getting closer and closer, and they could even see the big camphor tree logo on the helicopter.

Xie Changshan looked at the approaching helicopter and asked:
"Is the city lord coming again? I haven't received any news that the city lord is coming to Oil City."

"Probably not."

Ding Jiu looked around, shook his head and whispered:
"The food inventory in Oil City has decreased a lot. Now a large number of points are issued, and the exchange amount is not proportional. In order to avoid a run on the bank, some food is dispatched from the headquarters base."

"Ah? Is there a food problem in Oil City now?" Xie Changshan asked in surprise.

Ding Jiu glared at him.

Xie Changshan knew that he didn't dare to speak so loudly, so he quickly whispered, "I'm sorry, I was just too surprised."

Ding Jiu sighed and said:
"It's not a crisis. The current food reserves in Oil City can still support more than a month."

"But, for more than a month, the crops in the greenhouse cannot be harvested."

"It will take at least two more months before the greenhouses in Buffer City can start harvesting. In order to avoid food shortages in a month, we can only transport food through the headquarters base now."

“More than a month.”

Xie Changshan murmured:

"It's been more than a month, so the floods should have gone away. Why not wait for more than a month before transporting the food by land? As far as I know, the cost of transporting food by air is too high, and the amount of food transported is relatively small."

“It’s not worth it!”

Ding Jiu said:

"What if it rains later? No one can predict the weather these days. It can be sunny when it says sunny, or snowy when it says snow. In order to avoid a food crisis, the city lord and his men will naturally make preparations in advance."

"I see." Xie Changshan nodded.

Suddenly, he remembered something again.

He opened his mouth and asked:
"What's the situation at the headquarters base now? The headquarters base is located in the south, and the temperature rises faster. Will it affect the buffer city?
Logically speaking, the headquarters base should have been hit harder by the flood, but I didn’t receive any flooding information from the headquarters base.”

Ding Jiu smiled and said:

"You are wrong about this."

"Where is our big camphor tree base? It's in southern Jiangxi.

There are mountains and hills over there, and many small basins are formed among the mountains and hills. When the snow on the mountains melts, large and small lakes are formed, which cannot form a super large flood.

You can understand it as: the basin among the mountains becomes a lake, and as long as the water level of the lake does not exceed the mountain ridge, it will not flow into other places.

Generally speaking, places where floods cause greater disasters are in plain areas.

This kind of mountainous and hilly terrain cannot cause a particularly large flood disaster."

Ding Jiu paused for a few seconds.

He continued:
"However, the terrain in the west of the Dazhangshu base is relatively low, so the water level there will be higher. However, the source of the flood in the west of the Dazhangshu base is only formed by the snow on the surrounding mountains, so the amount of water is limited.

Moreover, the overall location of the headquarters base is relatively high compared to the surrounding areas.

The flooding is not that serious, but the western section of the wall is relatively low, and water is gushing out of the sewers. But with Fusheng and the others here, it should be resolved."

After listening to Ding Jiu's explanation, Xie Changshan breathed a sigh of relief.

"I see. Now I am not worried anymore."
