The host asked a middle-aged man in a black suit and glasses, "Director Chang, are these craters?"

Director Chang smiled and nodded, "Yes, because there is no atmosphere on the moon, its craters are very dense. We can see from the satellite remote sensing map that these densely packed are all craters."

"So, how did these craters form?" the host asked curiously.

"The formation of craters is caused by the impact of meteorites on the surface of the moon. The large craters on the moon are very huge, and we can see that most of the landmarks on the moon are craters. Among them, the maria we are familiar with, It was also formed after the impact of a huge meteorite, but it was very huge."

For example, Zhihai, where Haoyu Technology's Lunar Zhihai Lunar Surface Commercial Scientific Research Station is located, is actually an ancient large meteorite impact crater. "Director Chang explained.

"Oh, so that's the case. Then, if we want to build related buildings on it, it may not be easy. First, we have to consider filling up these craters." The host nodded and said.

"That's right, it's not a small project to level these 2,000 square meters of lunar surface, especially in the lunar environment. We can use all kinds of machinery on Earth, and we can also use a large number of people to work. But There are none on the moon, only two multi-purpose engineering robots and one intelligent control robot, and the construction progress can be imagined." Director Chang replied.

After listening to Director Chang's words, the host looked at Deputy Chief Engineer Cai at the side. Seeing this, Mr. Cai understood, and then smiled and said: "Smoothing the moon surface is only the first step, and the next step is to insert a lot of steel nails into the flat moon surface. Of course, the material of these steel nails is not It's made of steel, but light alloy, so it's lighter."

"These alloy ground nails will be evenly inserted into the more than 1,000-square-meter foundation according to a certain distance, so as to strengthen the rammed earth layer of the lunar soil below, and also provide anchor points for the floor tiles laid on it, making the floor tiles The laying is more solid. After these are completed, the next step is to lay floor tiles." Mr. Cai explained.

"The first is the bottom layer of floor tiles. They need to be evenly and tightly laid in the entire foundation of more than 1,000 square meters to form a well-balanced whole."

These floor tiles are very different from the floor tiles on our earth. They are all polygonal floor tiles printed by lunar soil 3D printers, or special-shaped floor tile structures. "

They are like the puzzles or Lego blocks we use, they can be tightly snapped together and not easy to fall apart. In this way, such a layer of floor tiles can form a solid whole. "Mr. Cai continued.

"And this is only the first layer, and a second layer needs to be laid on top of it. Using the first layer as an anchor point, a layer of floor tiles is covered on top of this, so that there are two layers of floor tiles, plus a rammed lunar surface, This is the three-tier structure."

In this way, the bearing capacity of the entire foundation structure can be greatly increased, and larger and heavier building structures and facilities can be carried. "

"In the two-story floor tile structure, some pipeline channels will also be buried and preserved, and these channels will be used to store and pass through some pipeline networks."

What we see now is that on the foundation of these two layers of floor tiles, floor tiles are laid to form a road network, and the entire foundation is divided into several areas, and then the construction is carried out in different areas. "

The host asked curiously: "Mr. Cai, there is already a foundation, why do we need to lay another layer of floor tiles? What's the use of this?"

The school role played by the host is not only to grasp the progress and rhythm of the whole program, but also acts as the audience's tongue, asking some curious and doubtful questions for everyone, so that the audience can better understand the content of the program.

Mr. Cai explained with a smile: "Of course there is a purpose. These roads will be used as passages for construction machinery to enter and exit in the future. If there are no such roads, the two layers of bricks on the upper layer of the foundation will be crushed when these construction machinery enters and exits." , it will be more troublesome to repair it.”

And if the road is paved, allowing construction vehicles to drive on the road will effectively protect the entire foundation from being crushed and reduce maintenance costs in the later period. "

The host asked: "Is there any more?"

Mr. Cai nodded and continued: "These paved road grids can also divide the functional areas of the entire lunar scientific research station, and then carry out construction according to the area, which is more clear and convenient for construction and management.

In addition, these roads will also serve as roads connecting various functional modules in the future, and they can still play a role after the construction of the lunar scientific research station is completed. "

The host said with emotion: "I didn't expect that every step of the construction of the lunar scientific research station would be so rigorous."

Mr. Cai said solemnly: "Any project must be rigorous, otherwise there will be problems. Especially on the moon, every step is very critical, and it will be related to the success or failure of the entire project."

Even in any of our deep space exploration missions, every small step, every action, every instruction, and even every parameter will affect the success or failure of the entire mission. "

Therefore, all the large-scale and seemingly romantic space and deep space exploration projects we have seen have rigorous and serious science and technology behind them, so that they can be successful. "

After Deputy Chief Engineer Cai's words fell, Director Chang on the side immediately added with a smile: "Actually, the progress of this project is really fast, UU Reading www.uukanshu.com Especially in the recent period, it can be said that it is a fast pace. "

Before the arrival of the Lunar Cargo 2 spacecraft, there was only the small lunar soil 3D printer sent by the Lunar Cargo 1 spacecraft on the moon. Its printing speed was relatively slow, so the construction progress was relatively slow, and only a small part was laid. "

Most of the remaining foundation projects, including road construction, are in charge of the newly sent large lunar soil 3D printer. The printing speed is very fast, and most of its construction progress has been improved. "

Let's put it this way, the time it takes for the small lunar soil 3D printer to print one floor tile is enough for this large lunar soil 3D printer to print ten floor tiles, and the efficiency has increased tenfold. "

"So fast!" The host showed a surprised expression.

Hehe, Deputy Chief Engineer Cai said with a smile: "The first small lunar soil 3D printer has a certain experimental nature, and its volume and power are relatively small. And because it is the first lunar soil 3D printer to operate on the moon , so there will inevitably be some problems during the operation of the lunar environment.”

And these problems have all been solved on the newly sent large-scale lunar soil 3D printer, so this is why, and dare to develop such a large-scale lunar soil 3D printer, the efficiency and speed are naturally improved. Most of the boost. "
