Doomsday Bunker Upgrade

After the construction of the defense line in the Middle East started smoothly, Chen Xin couldn't help but have some ideas about the dome city design that was turned out and rearranged.

The country wants to restart the construction of the dome city. He has confirmed this intention to the high-level officials. The high-level officials do have this idea, but they want to make adjustments to the original design plan of the dome city.

It has been said before that this design scheme was originally experimental, 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, after the dome city is built, it will not be finished, there will be a large number of scientific research institutions and staff to maintain, and breed and multiply species in it to establish the ecological circle designed by Chen Xin, make it Able to self-circulate and maintain stability.

Overall, this is more of a large research facility than a city.

For the current Yan Kingdom, the restarting of the dome city is obviously not to continue this research project, but to accommodate the people.

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. In order to survive, there is no way to live in an underground shelter, but if the situation improves, people should be allowed to return to the ground. living.

In fact, people in some areas and cities have begun to renovate the shelters they live in after the sun comes out again, and are preparing to return to life on the ground.

If it weren't for the war with alien creatures, the country would have wanted to move forward in this regard.

And restarting the construction of the dome city is an attempt for this purpose.

After all, life in the dome city is basically no different from the city before the disaster, except for the addition of a hood over its head.

Therefore, it is now necessary to adjust the functions of the dome city, from an experimental scientific research city to a more professional life city.

This is actually not difficult to achieve. The current Dome New City is such a city. The Dome New City, which accommodates hundreds of thousands of immigrants, is now an uncompromising living city, but in some respects, due to the limitations of the original urban design, And the need to support war operations at the beginning is different from a simple living city.

And the drawings after Chen Xin "optimized" again are very suitable.

After all, this is a city designed purely to accommodate the population and meet the needs of life.

This drawing was not only sent to the high-level person responsible for the defense line in the Middle East, but also the high-level domestic leaders also received the blueprint.

However, the cost of the dome city is still too high, and even if the country can now afford the cost of building a new dome, it is still a heavy burden.

So the executives expressed their intention to reduce costs to Chen Xin, hoping that he could optimize the drawings, at least so that the country could afford to build two dome cities at the same time.

In the face of this request from the high-level, Chen Xin did not refuse, but this is not easy to achieve.

If you want to reduce construction costs, in addition to reducing material input, it is to reduce labor costs. After all, these are the main costs of construction, and the land does not need to be included in the cost now. The land belongs to the country and does not need to be counted.

However, neither material nor artificial is very good for compression.

In terms of labor costs, there is actually no room for compression, unless it is said that the current construction methods can be improved on a large scale, and more work can be done with fewer workers, which can reduce costs.

But this is not something that can be done easily, and even if the labor cost is reduced, it will certainly not meet the requirements of the high-level countries that can afford the construction of two dome cities at the same time.

After all, the labor cost does not account for the bulk of the dome city, and the bigger cost is actually in the materials for building the dome.

When designing the support structure of the dome, Chen Xin deliberately chose light materials, and even the outer layer of the dome was made of EFTE airbags and light heat insulation materials, instead of using heavier materials such as glass.

These light-weight materials greatly reduce the weight of the dome itself, while maintaining sufficient structural strength. Coupled with some designs added by Chen Xin later, this is the dome new city that shelters the entire city of more than 100,000 people. dome.

But the use of this part of the material is also the biggest part of the construction cost of the dome city.

These materials themselves were relatively expensive materials even before the disaster, but at that time, there was enough industrial scale for mass production, which naturally suppressed the cost to an acceptable level.

But the current industrial scale is obviously not as good as before the disaster, and the domestic industrial production capacity also needs to support Europe and the Middle East, so there are not many resources that can be squeezed out.

If the cost cannot be reduced, with the current capacity of the country, it can only afford the construction of a dome city, or even a little tight.

However, if these materials are replaced with cheaper materials, 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 overturning everything.

Even for Chen Xin, this is not something that can be done easily.

However, he still convened relevant researchers to study this aspect and see how to meet the requirements of the high-level.

The first thing that was raised was the construction problem. Some people think that the current 3D printing technology can be used for the construction of dome cities. After all, this printing technology is convenient, and it 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 supporting structure of the dome can be printed directly.

But this is still not enough. Although this has indeed effectively reduced some construction costs, it still does not meet the standards required by high-level requirements.

If you want to really reduce the cost, you still have to make a fuss about the material.

Faced with this problem, the researchers who were called by Chen Xin proposed two diametrically opposed solutions.

One party hopes to be able to develop new materials. As long as they can develop materials that also meet the construction requirements and at the same time have a low cost, the high-level requirements can be achieved.

On the other hand, it is hoped to work hard on the structure. By optimizing the structure, replacing the original relatively expensive materials with cheap materials can also meet the requirements of high-level.
