"Limestone is enough. In recent days, nearly 3,000 tons of limestone have been mined every day. Now, tens of thousands of tons of limestone have been stockpiled in the buffer city."

In the oil city, conference room, Ding Jiuzheng stood up to report.

"The temperature has recently rebounded and the construction speed has accelerated.

It is predicted that the buffer city wall will reach a height of 20 meters in three days, and the greenhouse will be completed within half a month."

......

After Ding Jiugang finished reporting, Ju Tianrui immediately stood up to give suggestions.

"Minister, since limestone is enough, why not let the limestone miners and guards retreat. The temperature has reached minus five degrees Celsius, and some trucks will even sink into the ice when transported back."

Uncle San nodded and said, "Yes, please withdraw."

"Okay." Ju Tianrui was happy after receiving the permission of his third uncle.

In the past two days, Dongfeng and Deputy Zhang Tian reported to him about the risks of temperature rebound, and he was also a little worried.

Now the minister has agreed that the workers and the convoy will not go out tomorrow.

When limestone is excavated, there are more guards than miners.

Ten huge excavators shovel the blasted limestone gravel directly onto the truck, which is very efficient.

Uncle San looked at Anya, "Onya, how is the planting in the greenhouse now?"

Anya stood up and replied:

"There are 150 greenhouses that have been planted now. The planting is currently good, and the remaining greenhouses are also being sown continuously. After skillful operation of the planting personnel, their speed will be improved again."

"Not bad." Uncle San nodded.

Currently, there are three types of crops mainly grown in buffer cities.

Corn, potatoes, sweet potatoes.

Planting these three types of crops is extremely simple.

There are two ways to sow corn. One is live streaming, and seeds are sown directly on the ridge.

Another type is seedling transplantation. Now seedling transplantation is mainly used, because there are dozens of acres of mature greenhouses in the trading market.

Before the construction of the greenhouse in Buffer City, seedlings were already started. Now, once the greenhouse in Buffer City is built, it can be transplanted directly, and the speed is faster.

Growing potatoes is also very simple. Cut them into pieces, germinate them in a light place, and then sow them.

The method of planting sweet potatoes is even simpler. In addition to directly planting sweet potato tubers, it can also be cut with leaves, which is very easy to feed.

After planting, the subsequent field management weeding, fertilization and irrigation, as well as pest control and other work are familiar with Anya and others.

In terms of fertilizers, they mainly use organic fertilizers.

There are more than 200,000 people in the trading market, and the daily excrement is an astronomical amount.

After being stored in a closed cesspool, it can be used to fertilize the crops directly.

A lot of excrement in the cesspool was stockpiled, and the dozens of acres of greenhouses that had relied on the underground plantations and trading markets of ancient cemeteries were in use at all.

There is too much organic fertilizer, and it is almost full.

If it weren't for the fact that a greenhouse had been built now and a large amount of organic fertilizer was urgently needed, they would have been able to dig new cesspools.

Can't hold it any longer.

Now it is cold and the drainage and drainage pipes connected to the outside are frozen and cannot be discharged from the trading market. Therefore, once the cesspool is full, you can only dig new pits.

In addition, the cesspool is sealed and a large amount of biogas is generated inside. Once ignited with fire, it will explode. The explosion effect is tantamount to heavy artillery bombing.

So this is also the reason why survivors are not allowed to carry fire in the trading market.

In addition, the routes taken by the cesspool pipeline are completely different from those taken by the drainage pipeline, and the two do not conflict.

...........

Jie Changshan raised his hand.

Uncle San nodded slightly and motioned for him.

"Minister, there are still some shortcomings in the waterproofing project of the buffer city. The main reason is that I am worried that the fence gate may be impacted by floods, so I applied to use concrete to block it directly."

"If concrete is blocked, how can we open the door behind it? And if concrete is blocked, the door will be scrapped..." Uncle San frowned and said.

"No."

Xie Changshan explained: "We first used sandbags filled with sand behind the gate, and then poured them with concrete to strengthen the support."

"When the flood recedes later, we will drill the concrete with a drilling rig."

"And, unlike the concrete used in fence construction, the C60 specification is used, and the solidity is different and it is easier to break."

After hearing this, Uncle San nodded and said, "Since that's the case, then do what you said."

Although Uncle San has some understanding of many fields, he is not all-round.

In oil cities, governance policies have always been professional things.

He only evaluates the risks and asks questions, and lets the people below solve them.

The concrete mentioned by Xie Changshan actually has many specifications.

C10 ~ C15 grade concrete: It is of ordinary grade and is suitable for indoor floors, site pavements, garden landscapes, etc. that do not require load bearing.

C20 ~ C25 grade concrete: high strength, suitable for building components such as house frames, roof panels, outdoor floors, platform beams, etc.

C30 ~ C40 concrete: belongs to the high-strength level, suitable for large buildings, multi-story frame structures, bridges, tunnels, culverts and other load-bearing components.

C45 ~ C80 concrete: belongs to the ultra-high strength level, suitable for special engineering needs such as high-rise buildings, large-span bridges, nuclear power plants, etc.

The legendary C140 is rarely used.

In the Dazhangshu headquarters base, the concrete used in the fence is also the ultra-high strength level of C60.

The foundation is even more C140-level concrete. This concrete has no gravel stone and uses rebar wire as stone to directly resist the bombing of shells.

C60 concrete has become very strong. Before the end of the world, only the bottom and basement of large structures, or bridges, tunnels, water conservancy projects, etc. would be used.

It is a high-strength concrete that has strong pressure resistance.

In addition, the wall with a width of 7 meters is like a solid fortress, which can fully withstand the impact of floods.

If bombarded with conventional shells, it will take ten days and half a month to blow it through.

This fence provides the strongest barrier for the base to resist external threats.

The core of the subsequent meeting still discussed and studied the flood that could be predicted immediately.

Subsequently, the points in the current base were discussed.

Currency expert Sun Taidou raised his hand.

"Minister, the current huge daily expenditure points in the trading market are subject to certain risks... I think the following points must be done well..."

Due to the recent use of a large amount of intensive labor, the points spent are also measured in ten thousand units.

After these points of expenditure are given to residents in the trading market, the residents' purses can be seen to be fast. With money, they dare to consume, which also drives consumption in commercial areas.

The tax payments in the latest week also broke the record high, up 100% from the same week last month.

There are now more than 100,000 survivors working on the construction site of the buffer city, and the daily points spent has reached more than 100,000.

One point can buy 4 tortillas, and one tortilla is worth 0.25 points.

More than 100,000 points are converted into grain, divided by 4, and then it is 600,000 kilograms of grain, that is, 300 tons of grain.

The points given to workers a day are equivalent to nominal expenditure of 300 tons of grain per day.

However, these points cannot be redeemed within one day, and most people just keep them.

300 tons of grain a day, 3,000 tons in ten days, and 9,000 tons in one month.

At this consumption rate, you can't last too long.

If you want the horse to run fast, you have to let the horse eat some grass. If the residents do not give points, they will naturally have no motivation to work.

Under such a good system, residents' enthusiasm for work will be more high.

After recruiting and recruiting residents for construction projects, the points distributed this month reached 4.5 million.

The inverted cordon is getting closer and closer.

The meaning of upside down is that all the points available to all residents are compared with the food in the oil city.

The amount of food that can be exchanged for all the points that can be exchanged for more than the actual amount of food that the oil city has, which is an inverted reversal.

But now, the upside down will not immediately lead to a crisis.

As long as the subsequent buffer city greenhouse is completed and grain is planted, this problem can be alleviated.

In short, it is to first borrow the survivors' labor force, distribute points to them, and slowly cash out the food.

The reason why we can achieve this is due to the endorsement of the Oil City for so many years and the guarantee of the Dazhangshu Base headquarters behind it.

In case the oil city has no food and the residents of the trading market will exchange it with points. Even if the oil city cannot exchange it for food, the headquarters of the Dazhangshu Base can still provide reinforcements.
