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

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

"So, how are these craters formed?" 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. We can see that most of the landmarks on the moon are craters. Among them, the lunar maria we are familiar with, It was also formed after the impact of a huge meteorite, but it's just very huge."

For example, the Zhihai lunar surface commercial scientific research station of Haoyu Technology is located in Zhihai, which is actually an ancient large meteorite impact crater. "Director Chang explained.

"Oh, that's it. Then, if we want to build related buildings here, it may not be easy. We must first consider filling in these craters." The host nodded.

"Yes, flattening these two thousand square meters of lunar surface is no small project, especially in the lunar environment. On Earth, we can use various machines, and we can also use a large number of people to work. But There are none on the moon. There are only two multi-purpose engineering robots and one intelligent control robot. The construction progress can be imagined." Director Chang replied.

After listening to Director Chang's words, the host looked at Deputy Engineer Cai on the side. Upon seeing this, Mr. Cai understood, and then said with a smile: "Smoothing the moon surface is only the first step, and then you need 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 of light alloy material, so it’s lighter.”

"These alloy ground nails will be evenly inserted into the foundation of more than 1,000 square meters at a certain distance, thereby reinforcing the rammed soil layer below and providing anchor points for the floor tiles laid above, making these floor tiles more durable. The laying is more secure. After these are completed, the next step is to lay the floor tiles." Mr. Cai explained.

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

These floor tiles are very different from the floor tiles on our earth. They are polygonal floor tiles printed using a lunar 3D printer, or special-shaped floor tile structures. "

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

"And this is only the first layer, and a second layer needs to be laid on top of it. Use the first layer as an anchor point, and cover it with another layer of floor tiles, so that there are two layers of floor tiles, plus a tamped moon surface. That’s the three-tiered structure.”

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

"Between these two layers of floor tile structures, some pipeline channels will also be filled in and retained, 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 part is divided into several areas, and then construction is carried out in separate areas. "

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

The role of the host is not only to control the progress and rhythm of the entire program, but also to serve as the tongue of the audience, 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 it has a purpose. These roads will be used as passages for the entry and exit of construction machinery in the future. If there are no these roads, these construction machinery will crush the two layers of bricks on the upper layer of the foundation when entering and exiting. , it will be more troublesome to repair it.”

And if the road is paved and construction vehicles are allowed to drive on the road, it will effectively protect the entire foundation part from being crushed and reduce later maintenance costs. "

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 areas. This will be clearer and more convenient for construction and management.

In addition, these roads will also serve as roads connecting various functional modules in the future and 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 this lunar scientific research station would be so rigorous."

Mr. Cai said seriously: "Any project must be rigorous, otherwise problems will occur. Especially on the moon, every step is very critical, and it will determine 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 deep space exploration projects we see are supported by rigorous and serious science and technology, so that they can succeed. "

After Deputy Chief Engineer Cai finished speaking, Director Chang on the side immediately added with a smile: "Actually, the progress of this project is really very fast, especially in recent times, it can be said to be a rapid 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 slow and only a small part was laid. "

Most of the remaining foundation projects, including road construction, are handled by the newly delivered large-scale lunar soil 3D printer. The printing speed is very fast, and its construction progress has been greatly 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, which increases the efficiency tenfold. "

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

Haha, Deputy Chief Engineer Cai on the side said with a smile: "The first small lunar soil 3D printer has a certain experimental nature, with a relatively small size and power. And because it is the first lunar soil 3D printer operating on the moon, , so it is inevitable that there will be some problems during operation in the lunar environment."

And these problems have also been solved on the newly delivered large-scale lunar soil 3D printer. That’s why we dared to develop such a large-scale lunar soil 3D printer. The efficiency and speed have naturally been improved. Mostly improved. "
