Doomsday disaster: Start by building a shelter

And that's just for the current engineering team.

Based on Suwu's current industrial productivity.

If you really want to, it is not difficult to expand the size of the engineering team several times, or even more than ten times, in a short period of time.

This is also the beginning.

Su Wu saw the technology of rapid cement.

This is why I subconsciously think that after lighting it up, I will no longer have to worry about insufficient space.

In addition to the core project of expanding the farmhouse.

With the support of 7 million tons of fast cement reserves and an engineering team that can expand the scale unlimitedly at any time and anywhere.

The underground transportation network once daunted Su Wu because it consumed too many resources.

It can also be really put on the agenda.

At that time, wait until the underground transportation network is completed.

Su Wu's farmhouse and several other affiliated shelters will be completely connected as a whole.

Become a real underground kingdom.

Have a stronger development speed and the ability to deal with natural disasters.

As for how to build an underground transportation network specifically.

Su Wu also has a preliminary plan.

The first is the underground passages that will form the transportation network.

It is further subdivided into passenger passages and material transportation passages.

Needless to say about the passenger access.

Mainly used for transporting personnel, the construction standard is relatively high.

But it’s the end of the world now, and no matter how high the standard is, it’s not that high.

At least it's certainly not as good as the subway.

In Su Wu's plan.

The passenger passage will be a one-meter-wide, 1.7-meter-high tunnel that will allow only one-way traffic.

Vault residents can travel through the tunnels in a vehicle similar to a playground train.

This kind of transportation efficiency will not be too high.

A 20-meter-long miniature train can only carry a maximum of twenty people at a time.

But still the same sentence.

Resources, safety, etc. in the apocalypse are more precious than people's time.

Transferring through the passenger passage is at least much safer than traveling on the ground.

If the efficiency is low.

It can also be compensated by running 24 hours a day and increasing the number of round trips.

Moreover, between various affiliated shelters.

Under normal circumstances, there are not that many personnel transfer needs.

There will be no travel, family visits, etc.

Most of them are job transfers between each other.

In this case.

The miniature train is sufficient and can even be used to transport supplies.

Compared with the passenger passage, the size of the material passage is more compact.

When no one is required.

General resources.

It can basically fit in a cargo box with a width and height of no more than 0.5 meters.

The only difference is that it is divided into batches multiple times, or the whole thing is dismantled into parts, transported to the destination, and then reassembled.

Under this severe restriction on channel size.

The time and cost of excavation and construction of tunnels in Suwu will be reduced to the greatest extent.

No need for lengthy construction at all.

"By the strength of fast cement."

"The thickness of the passage wall should be kept at 5 millimeters, which is almost enough."

"After all, the passage itself is not big, and the pressure it endures is not at the same level as a serious underground train tunnel."

"At the same time, as a passage, it doesn't need to be as strict as building a shelter."

"Even if there is an accident in the middle, the single loss will not be much."

"That's how it counts."

"Converting the gravel truck into a micro-shield machine of corresponding size should be able to dig a distance of about one meter in one minute."

"And then work on it from both ends simultaneously."

"It is estimated that a material channel nearly 3 kilometers long can be dug out in one day."

"The passenger passage is slower, but it can still be close to 1 kilometer."

“Also, consider that air is not required for supply channels.”

"It can be completely vacuumed."

"In this way, at least the transportation speed will be faster."

"We can go one step further in the future and change it to a maglev transportation mode."

In front of the console, Su Wu used artificial intelligence.

A simple calculation was made on the cost and construction time of building passenger passages and material passages.

Found due to strict constraints on channel size.

Both the cost and the construction progress are far lower than originally estimated.

This made him become even more bold.

Directly on the map.

At the same time, the construction plan of five passenger passages and seven material passages was launched.

Connecting the farmhouse and all the affiliated shelters in one go.

"The plan is complete."

“Next, it’s time to start implementing them one by one.”

Su Wu is marked on the map.

He turned his attention to the newly expanded area on the 8th underground floor that had been completed a week ago.

It was according to the original plan.

Those areas will still become testing grounds for simulating various terrains and extreme environments.

But now, since rapid cement, a heavyweight basic material, has been developed.

Then we can only appropriate part of that space.

Used to prioritize the construction of production lines for the production of rapid cement.

"Concrete crusher, high-temperature distillation ball, reactor-"

Su Wu added the production line equipment to the task list of the manufacturing center one by one.

And unceremoniously cut them all in line and listed them as the first items to be manufactured.

Compared to the production of fast cement.

Even the production of capsule grids can be postponed.

After all, there is no place to live.

Those seriously infected can also stay in their original shelters first.

And the earlier the fast cement is produced.

Su Wu can accelerate the expansion of the shelter space earlier, thereby increasing the number of plantations.

Alleviate the daily food demand of the population that has now expanded to more than one million.

Of course, this kind of queue-cutting can only be used occasionally.

Leaving the seriously infected in other shelters is fine for a short time.

If the time is slightly extended, problems will inevitably arise.

Those seriously infected, in the eyes of the senior management of other shelters.

It is almost the same as the pollution source of wasting food.

Once the speculation that Su Wu is unable to accept it is born, it is hard to say that he will not do something radical.

"Wait until the fast cement production line is completed."

"First, increase the current construction efficiency of the engineering team to the maximum of 1,000 square meters per day."

"Then start from the 7th underground floor."

"All the additional space will be used to fill the plantations that produce fast-growing food."

"From now on, the plantations in Jingyuan Shelter and Zhou Xiwu Shelter will be gradually closed down."

"Then reduce the number of broiler farms by about two-thirds."

"Free up space and continue to build standard dormitories using ordinary cement."

"Also, the two medium-sized shelters of Qingning and Li Rong can do the same."

"All of them will be used to build dormitories."
