Bazhong City, Shu Province.

Jianmu No. 2 is located near the city's Pyeongchang county.

Since this mass projector is owned by the Dongtang Space Agency, many projects are being done by state-owned enterprises.

As the person in charge of this base, Zhao Hongxing, Wang Guanghai and others are inspecting the progress of the project.

Wang Guanghai tapped the huge steel pillar on the side with his fingers: "Is this counterweight strong?" Don't drop the chain at that time! ”

"Don't worry!" Zhao Hongxing pointed to the huge steel pillars that were driven into the mountain or foundation and said: "Each of these steel pillars weighs 10 tons, and a total of 10,000 steel pillars of this level are used in the entire base. ”

"Oh? In this case, wouldn't the overall weight of the counterweight exceed 100,000 tons?" Wang Guanghai asked.

Zhao Hongxing nodded: "That's for sure, because it is also necessary to connect these steel pillars into one, welded steel frames and reinforced concrete layers, etc., after adding them, the estimated height of the entire counterweight is about 300,000 tons." ”

The reason for using such a huge counterweight is mainly because the magnetic vacuum cable will produce a huge buoyancy when it is in the state of vacuum excitation, which is as high as 2~30,000 tons, and if it is not fixed and the counterweight is added, the vacuum pipe may be torn off.

"Even if the counterweight is so large, it still can't be taken lightly, after all, this is the first time we've made this thing." Wang Guanghai suggested.

"That makes sense, I'll ask the engineering department to do a few more supercomputing simulations."

"Especially the balance of the counterweight, you must calculate it well, just in case."

Zhao Hongxing nodded: "Lao Wang, let's go to the mass projector and take a look!" ”

"By the way, is the old horse over here?"

"Old horse? He's here this month, and he's going to Kaohsiung in May. ”

"Let's go! I was just going to talk to the old horse. ”

The group walked and inspected the construction of the entire base.

Since the main project of Jianmu No. 2 base has not yet been completed, the mass projector is not in the main body of Jianmu No. 2, but in the supporting factory on the side.

Academician Ma, who was debugging the mass projector, was concentrating on communicating with a large group of researchers or engineers.

"Old horse, don't come unharmed!"

As soon as Academician Ma heard this voice, he knew who was coming, turned his head and shouted to the visitor: "Lao Wang, why do you have time to come here?" Projection ship done?"

"That's so fast, the project is now with Lao Li, I'll come and see your progress, and by the way, exchange the situation." Wang Guanghai replied with a smile.

"I thought you had taken hormones and got the projection ship out." Academician Ma said as he motioned to the researchers and engineers to go and get busy.

"Haha! You old boy, you think building a spaceship is kneading dough! Let's get out! Where's your projector progress?"

"It's almost."

"So fast?"

"The technology has been verified, that is, it is to enlarge some, the details can be improved and checked, and after the Qinling X-ray base is put into use, the output of superconductors at room temperature has increased greatly, and there is no problem with raw materials, of course, the progress is fast." Academician Ma replied with a smile.

"Envy and jealousy!" Wang Guanghai joked.

"Since you're here, let's come and have a look!" After Academician Ma finished speaking, he took Wang Guanghai and others to the production workshop of the quality projector.

In fact, it is not so much a production workshop as a huge factory.

The entire production workshop is 84 meters high and covers an area of nearly 26,000 square meters.

The whole mass projector, like a huge mortar, of course, from another point of view, this thing can really be called a huge cannon.

However, a normal cannon fires cannonballs, while it fires spaceships.

"How are you going to transport this thing to Jianmu Base 2?" Wang Guanghai looked at the mass projector and asked.

After all, the height of this mass projector is about 40 meters, and the overall weight may be as high as several thousand tons, which is still a part, according to the design, and some of the guide rails will be installed after the mass projector enters the Jianmu No. 2 base.

Academician Ma pointed to the bottom of the mass projection: "Below is something similar to a launch vehicle transport platform, and in addition, this plant can be opened directly." ”

Wang Guanghai approached the railing and looked at the bottom of the mass projector and the structure of the factory: "I see. ”

"Otherwise, do you think we built it here, then dismantled it, and then transported it to Jianmu No. 2 to install it?"

This mass projector factory is located on the south side of the Jianmu No. 2 base, and the distance between the two places is about 5 kilometers, and there is a huge transportation platform track directly connecting the two places.

"This thing uses a lot of room-temperature superconductors, right?"

"That's a lot, about 270 tons! It's mainly to enhance explosiveness and redundancy, so it's a little more than the original plan! Academician Ma spread his hands and replied.

"Huh! Quite a lot? Old horse, you have expanded, a ton of 50 million Chinese yuan of room temperature superconductor, you have exceeded the original plan by nearly 100 tons! Wang Guanghai shook his head and smiled bitterly.

"No, now the price of room temperature superconductors has been reduced, about 40 million a ton!" Academician Ma replied with an innocent face.

Isn't 40 million tons money? Wang Guanghai thought speechlessly.

Academician Ma turned his head to Zhao Hongxing and asked, "Let's not care about this kind of trivial matter, Hongxing, how is the main body?"

"Construction is underway, and it has been carried out to about 180 meters." Zhao Hongxing replied.

The design height of the main body of the entire Jianmu No. 2 base is 560 meters, and foam cement and steel bars are used for rapid construction.

Of course, the rigid vacuum pipe inside is made of the same material as the vacuum pipe of the Strait Bridge, but the radius and thickness of the vacuum pipe have been greatly increased.

If you do not thicken the thickness of the pipe wall, it will not be able to withstand the pressure of atmospheric pressure at all, after all, it is a vacuum pipe with a length of 560 meters and a radius of 96 meters.

"Is it already more than 180 meters? Why can't you see it! Wang Guanghai asked with some confusion.

Zhao Hongxing smiled and clicked on the holographic projection and explained to him:

"This is the main body of Jianmu No. 2, which is very similar in shape to the pyramid, and of the 560 meters of hard vacuum pipes, 50 meters are underground, and the remaining 510 meters are above ground."

Wang Guanghai looked at the holographic projection model and found that this design did have the effect of visual deception, unlike those high-rise buildings like bamboo poles, the pyramid-shaped design looked shorter at a glance.

The main reason for this design is to allow the main body to extend the rigid vacuum pipe as much as possible, and also to combine with the counterweight underneath, while also ensuring stability and durability.

After all, Jianmu No. 2 base may be used for decades in the future, and it will not work if it is not durable.

The three of them took the elevator to the top construction site of the main body of Jianmu No. 2.

As soon as he came up, Wang Guanghai knew that this thing was huge.

A huge hole with a radius of 96 meters appeared at his feet, and he saw the main structure being poured foam cement, which was indescribably large.

The base of the main body is a near-circular with a radius of 800 meters, covering an area of 2 square kilometers.

Although the cross-sectional area decreases with the height due to the pyramid-shaped design, the cross-sectional area is already very large at a height of about 180 meters.

Even some large construction vehicles can run around on it.

There are also a number of large transport airships that also help transport materials at the construction site.
