Chapter 858

As soon as the last batch of palace roof modules were transported to the construction site, Jiang Cheng called all the management personnel to hold an engineering meeting in the engineering headquarters.

"Now that the prefabricated modules of the roof have arrived, we will start to write about the construction of the roof.

You go down to inform the astronauts of each unit, and then concentrate on completing the top project

let's hurry to finish the most difficult part of the work, and we can be a little easier

Jiang Cheng stood in the middle of the project headquarters and gave follow-up orders to all the management personnel around him.

The next work is the key point of the whole project. I hope everyone can cheer up. As long as we can complete the construction of the roof with care, even if the whole project is half finished, the most difficult part of the whole project will start soon. Now even Jiang Cheng is a little nervous.

That's why he repeatedly stressed this matter in the engineering headquarters, hoping to attract everyone's attention.

Judging from the construction time of the whole city, the construction of the roof will occupy half of the time.

From this we can see the importance of this project. No wonder Jiang Chenghui is so nervous.

After the construction meeting, everyone dispersed and began to carry out different work.

In the top brain industry, everyone has his own responsibility. Only with concerted efforts can we complete this super project.

In Zhoutian of the construction site, there is a four shaped structure.

This huge circle is the foundation of the roof, which bears the weight of the whole roof.

Now that the foundation of the whole dome has been built, the construction of the ground part will begin next.

I saw huge lifting robots, lifting huge legacy modules from the stacking place to the predetermined place.

Each prefabricated block of the palace roof is numbered, and the long string of numbers represents where he should be placed.

The lifting work is not so simple. It needs a good overall planning before the whole dome is composed of numerous prefabricated blocks. Because there are too many prefabricated blocks, it is a huge problem to put every prefabricated block where it should be.

There are so many prefabricated blocks piled up at the site that if you don't pay attention to them, they will be placed wrongly and the subsequent assembly work will be shelved.

It took Jiang Cheng several days to put all the modules in the predetermined place.

The preparatory work alone will waste so much time, and the difficulty of the construction of the palace roof is reflected here.

Putting the prefabricated blocks in place is just the beginning. The assembly work behind is the real difficulty.

This kind of construction technology of prefabrication and installation is much simpler than integral molding construction.

However, this is relatively simple. Although it's just assembly work, there are many problems to be considered.

It's not the top of a water ball, it's the top of a protective layer on Mars.

Therefore, the transparent dome must be absolutely sealed.

If there is a dimension gap between precast blocks, even a small gap will cause great disaster.

When Jiang Cheng built the whole palace roof, he had to make sure that every prefabricated block was perfectly jointed, and then he had to weld them together with special technology to form a solid whole.

Each prefabricated block can be calculated in advance before production, there is a piece of installation error is not good.

Therefore, during the installation construction, it is necessary to ensure that each prefabricated block is installed in the planned place without installation error.

There are too many things to pay attention to in the whole project. Lian Jiangcheng always had to walk on the site during the construction.

After more than two months of construction, the construction of the roof is still going on, and Jiang Cheng stands at the construction site, watching his astronauts install the prefabricated blocks.

One by one, the prefabricated blocks were not suspended in the air, and they began to be spliced together with other prefabricated blocks

under the reflection of sunlight, the remaining prefabricated blocks shone brilliantly.

If the helmets on the spacesuits were not equipped with strong light filtering function, the eyes of people at the scene would not be able to open.

Numerous transparent modules are moving in the air and are hoisted to the predetermined assembly position.

The most difficult thing is that when several prefabricated blocks are close to each other, they have to adjust their respective positions repeatedly so that they can be spliced together.

After several prefabrication processes are completed, each prefabrication process can be strictly inspected, and when there is no "zero gap" between them, they can be inspected.

After splicing, astronauts will use special equipment to connect the transparent prefabricated blocks together.

This kind of welding equipment is specially made by Jiangcheng, so that people can't see the traces of welding when the welding is firm.

This special welding method ensures the transparency of the whole palace roof, and will not cause problems due to welding.When the whole roof is assembled, it looks like a whole, and it doesn't even know the slightest crack.

When you stand inside the city and look up at the sky, it's like you're outside Mars, and you can't detect the existence of a transparent dome.

Perhaps only after repeatedly adjusting the angle can we barely see the wheel on the top of the palace.

This kind of design is what Jiang Cheng wants to achieve most. It can make people in the city feel no bondage, just like staying on the surface of Mars.

While Jiang Cheng was inspecting the construction site, Xiao Peng came to Jiang Cheng and said, "the precast block in A37 area has been hoisted and is about to be completed. Do you want to go and have a look.

The construction of the whole roof is divided into innumerable districts, each of which is installed by a specially assigned person.

Many areas are under construction at the same time. Only in this way can the efficiency of the project be guaranteed. If the installation is carried out slowly bit by bit, they may not be able to complete the installation for several years.

So in the end, they adopted the segmented installation mode, each area first installed a part of the palace roof, and finally connected different areas.

However, in this way, it is very important to coordinate with each other. If the two areas can not be connected in the end, they will have to be disassembled and reassembled.

In order to prevent this kind of thing from happening, Jiang Cheng and his colleagues must inspect the scene at any time and coordinate the progress between different areas, so that they can finally assemble the palace roof together.

As the whole Martian city covers a large area, Jiang Cheng does not know about other areas.

After hearing the news reported by Xiao Peng, Jiang Cheng decided to go and have a look.

The progress over there is pretty good. Let's go and have a look.

After that, Jiang Cheng took the lead and went to the next Mars rover, ready to go and have a look with Xiao Peng.
