After the construction of the defense line in the Middle East began to proceed smoothly, Chen Xin couldn't help but have some ideas when looking at the dome city design drawings that had been dug out and rearranged.
The country wants to restart the construction of the dome city. He has confirmed this intention to the senior officials. The senior officials do have this idea, but they want to make adjustments to the original design plan of the dome city.
As mentioned before, this design plan was originally experimental in nature, with the purpose of studying the coexistence between humans and the ecological environment, and the restoration of the ecological environment after disasters.
According to the original design, the dome city is not finished after it is built. There will be a large number of scientific research institutions and staff to maintain it, and to cultivate and multiply species in it to establish the ecosystem designed by Chen Xin and make it Able to maintain self-circulation and remain stable.
Overall, this is more of a large research facility than a city.
For the current Yan State, restarting the construction of the dome city is obviously not to continue this research project, but to accommodate the people.
Ever since the sky was purified and the sun rose again, the country has actually been planning to bring the people living underground back to the surface.
After all, as we all know, people need to bask in the sun. Living underground for a long time will have various negative effects on the body. There is no way to survive in underground shelters, but if the situation improves, people should still be allowed to return to the surface. of life.
In fact, people in some areas and cities have begun to renovate the shelters where they live after the sun comes back, and are preparing to return to life on the ground.
If it hadn't been held back by the war with alien creatures, the country would have already wanted to advance this matter.
Restarting the construction of the dome city is an attempt for this purpose.
After all, life in the dome city is basically the same as the city before the disaster, except for the addition of a cover above the head.
Therefore, it is now necessary to adjust the functions of the dome city from an experimental scientific research city to a more professional and relevant living city.
This is actually not difficult to do. The current Dome New City is such a city. The Dome New City, which accommodates hundreds of thousands of immigrants, is now an out-and-out living city. However, in some aspects, due to the limitations of the original urban design, And the original need to support war operations is different from a simple living city.
The drawings after Chen Xin's "optimization" again were very suitable.
After all, this is a city designed purely to accommodate the population and meet living needs.
This drawing was not only sent to the senior executive responsible for building defense lines in the Middle East, but also the senior officials in the country also received the drawing.
However, the cost of building a dome city is still too high. Even if the country can now afford to build a new dome, it is still a heavy burden.
So the senior management expressed to Chen Xin whether the cost could be reduced, hoping that he could further optimize the drawings, at least so that the country could afford to build two dome cities at the same time.
Faced with this request from the top management, Chen Xin did not refuse, but this was not easy to achieve.
If you want to reduce construction costs, in addition to reducing material input, you must also reduce labor costs. After all, these are the main construction costs, and the land does not need to be included in the cost now. The land belongs to the country, so there is no need to calculate money.
However, neither materials nor labor are easy to compress.
In terms of labor costs, there is actually no room for reduction, unless the current construction methods can be improved on a large scale and more work can be completed with fewer workers, then costs can be reduced.
But this is not something that can be easily accomplished, and even if the labor costs are reduced, it will definitely not meet the requirements of the high-level officials for the country to be able to afford the construction of two dome cities at the same time.
After all, labor costs do not account for a large part of the dome city. The greater cost is actually the materials used to build the dome.
When designing the support structure of the dome, Chen Xin deliberately chose lightweight materials, and even the outer layer of the dome was made of EFTE airbags and lightweight insulation materials instead of using heavier materials such as glass.
These lightweight materials greatly reduced the weight of the dome itself, while maintaining sufficient structural strength. Together with some new designs that were added later, the Dome New City was created, which sheltered an entire city of hundreds of thousands of people. dome.
But the use of these materials is also the largest part of the cost of building a dome city.
These materials themselves were relatively high-cost materials even before the disaster, but at that time there was enough industrial scale for mass production, so the cost could naturally be suppressed to an acceptable level.
But the current industrial scale is obviously not as good as before the disaster, and domestic industrial production capacity also needs to support Europe and the Middle East, so there are really not many resources that can be squeezed out.
If the cost cannot be reduced, the country's current affordability will probably only be able to afford the construction of a dome city, and it may even be a bit tight.
However, if these materials are replaced with cheaper ones, it will affect the weight and structure of the dome. If you want to do this, you must overturn the original design, which is equivalent to tearing everything down and starting over.
Even for Chen Xin, this is not something that can be accomplished easily.
However, he still convened relevant researchers to study this issue to see how to meet the requirements raised by senior officials.
The first thing that was raised was the issue of construction. Some people think that the current 3D printing technology can be used in the construction of dome cities. After all, this printing technology is not only convenient, but also can save labor investment.
Chen Xin quickly adopted this suggestion and designed a new type of 3D printing equipment that can be used for dome construction. As long as the materials are available, the dome's support structure can be printed directly.
But this is still not enough. Although this has indeed effectively reduced some construction costs, it still cannot meet the standards required by high-rise buildings.
If you want to really reduce costs, you still have to make a fuss about materials.
Faced with this problem, the researchers summoned by Chen Xin proposed two completely opposite plans.
One party hopes to develop new materials. As long as materials that also meet construction requirements and are low-cost can be developed, high-rise requirements can be achieved.
On the other hand, they hope to work hard on the structure. By optimizing the structure and replacing the original more expensive materials with cheaper materials, they can also meet the requirements of high-rise buildings.
