Chapter 857

And astronauts are in rotation at any time, and wells won't stay on Mars for a long time.

The residents of Mars city are totally different. If they are allowed to live in closed buildings in the future, it is estimated that some people will go crazy soon.

Therefore, a Mars city should at least use a certain amount of external space for residents' activities in the city.

Finally, Jiang Chengcai chose the current design scheme, all the buildings are in the open air environment.

This Martian City, Jiangcheng, is going to arrange ordinary buildings in the city, which are exactly the same as those on the water polo. The well won't let all the buildings be closed.

But this kind of design mode needs to design a protective layer in the outer area to isolate the whole city from the outside environment.

So Jiang Cheng came up with a way to protect the whole city by building a dome.

Jiang Cheng is going to build a huge roof in the outer area of the city to encircle the whole city.

In this way, the low temperature outside and the air that is not suitable for human breathing will not affect the human in the city.

The whole top writing is just like a protection to protect the people inside.

Although such a design scheme is much better for the residents inside, it adds numerous difficulties to the construction.

It's a hard job just to think about the huge palace roof that can encircle the whole city.

On water polo, it's just to build the top of a gymnasium in the bag area, and I don't know how much work it will take.

Now Jiang Cheng wants to build the palace roof of a city in Baoqu, which is a super project.

It can be said that the construction of the roof is the most difficult and smooth part of the whole project.

Jiang Cheng is now busy with this aspect of things, and now he has encountered one of the biggest difficulties in the project.

How to build this huge roof is a question Jiang Cheng is thinking about recently.

The materials for the construction of the palace roof have already arrived. I don't want to see the shortage of materials during the construction.

Jiang Cheng is in the project command center, asking Ruo about materials.

The materials needed for such a large palace roof are astronomical.

It is estimated that all the materials needed for the construction of the palace roof are more than those needed for the whole city.

In terms of engineering quantity, the construction of the palace roof accounts for more than half of the whole project. No wonder Jiang Cheng is concerned about this.

Now the construction of Hengding is about to start. If there is not enough material supply, the progress of the whole project will be greatly delayed.

The last batch of materials has been produced and can be transported from the water supply bulb immediately. "You don't have to worry about the problems of materials, Mr. Jiang. You can certainly keep up with the progress of our construction.

Tong confirmed this to water polo yesterday, so he is very clear about it.

The materials used to build the roof are quite special. There is no way to produce it on Mars, so it can only be manufactured on the water ball and transported to Mars for installation.

Many of the materials used to build a Martian city are made locally on Mars.

After several years of development, the mining industry on Mars has been very developed, which can provide them with construction work.

However, many materials have to be transported from the water polo due to the difficulty of production, and the construction material of the top is one of them.

The palace roof designed by Jiang Cheng is made of transparent material, and its firmness is much stronger than that of steel. It can completely withstand the harsh climate on Mars.

Such advanced materials can't be produced, so they have to be transported here.

The dome made of transparent materials is also transparent, so the city will have a transparent palace in the future.

Imagine that the residents of this city can look up and see the starry sky on Mars. This city feels great.

If the roof is not transparent, then the residents of this city will live in a large stadium.

No one will leave this building, which is not much different from the enclosed building.

It is because Jiang Cheng has similar considerations that he plans to use transparent materials to build the whole palace roof.

Of course, after the use of transparent materials, the difficulty of construction again improved a lot.

The transportation of these materials alone is a big problem. In order to transport the materials for the palace roof, Pioneer has been running back and forth a lot recently.

Basically, most of the materials transported from the water polo are from the palace roof.

After all the prototypes are prefabricated, they are transported from the water ball to Mars.

And then they were assembled on Mars to form a finished dome.

This process seems to be very troublesome. There are several more processes than direct construction.

the transportation of these prefabricated blocks is a big problem. The transportation of formed modules is many times more difficult than the raw material area, and the production on water polo is also a lot more difficult.In order to transport the prefabricated blocks of the palace roof, Pioneer has been running back and forth a lot recently.

Basically, the materials transported from the water polo, the palace roof, accounts for the vast majority of the transportation volume

that's why Jiang Cheng is so concerned about this aspect, that is, he is afraid that the prefabricated blocks will not be transported to Mars on time.

Although this kind of construction technology is difficult to transport and manufacture in advance, it is not without advantages.

This technology can show its advantages when it is built, and it is many times more convenient than the usual way.

Because the transportation is all prefabricated top module, so Jiangcheng they just need to assemble it.

Just pay attention to the serial number of the module when assembling. The shape of each module is different. If the installation place is not right, it will be very smooth.

In this way, the construction of the roof is difficult.

Otherwise, it would be impossible to build such a big roof on Mars.

It's very difficult to build such a huge top on a water ball, let alone in the harsh environment of Mars.

Fortunately, now Jiang Cheng doesn't have to worry about these difficulties. He just needs to arrange the assembly work.

Anyway, all the modules have been numbered in advance, so the astronauts just need to assemble the dome according to the number.

Although the work of the whole roof is very large, but there are robots to help if the assembly, so this work can be completed.

As long as the follow-up command of Jiang Cheng is proper, a transparent giant palace top will appear on Mars.

And after the completion of the construction of the dome, the construction of the back will become much easier.

With the word top to protect all astronauts, we do not have to worry about the impact of the external environment, just focus on the work.

When pioneer arrived on Mars with the last modules, the transparent dome was still under construction.
