The level of overt and covert struggle between countries is too high, and a small person like Ye Han cannot touch that level at all. He and all the astronauts stationed on the moon focus on the construction of the base.
With the gradual expansion of Base No. 1, food production gradually increased, and the number of astronauts sent to the moon also increased, further accelerating the construction of the base.
In early June, the tunnel construction site.
There was a muffled sound, and the entire tunnel trembled. Countless boulders fell from the sky. The collapsed tunnel severely crushed the laser boring machine under the pile of rocks.
"It's collapsed, it's collapsed!" The construction team immediately became confused and immediately reported the news.
After receiving the news, Gao Kai's head was as big as a bucket and he was in a very depressed mood. However, his first priority right now was not to figure out the cause of the landslide, but to rescue people first!
He rushed to the construction site immediately: "How is he? Have you contacted him?"
The excavation team leader replied: "We have contacted him and he is fine."
After the smelting team established production capacity, the shortage of metal materials was greatly alleviated. The tunnel boring machine, which was originally just a chassis and laser equipment, has now been covered with a thick layer of ultra-low temperature titanium alloy armor, and the carbon fiber wheels have been replaced with tracks of the same material.
It is better to say it is a laser boring machine than a laser boring tank.
However, no matter how strong the protection is, it cannot withstand the weight of hundreds or thousands of tons of rock.
Gao Kai breathed a sigh of relief: "As long as everything is fine, how long will it take?"
"Two hours." said the excavation team leader, "Xiao Zhou still has two hours of oxygen."
Gao Kai looked at the tunnel blocked by boulders: "How long did it collapse?"
"More than twenty meters."
"Can I get through in two hours?"
The excavation team leader shook his head: "It's very difficult. It may collapse again at any time."
Gao Kai's temples were pounding: "Go all out, whether you need people or equipment, I will send them to you!" It will collapse sooner or later, but it will collapse at the critical point when the tunnel is about to be connected. What's going on?
"It's not about the people and the equipment." The excavation team leader shook his head, "The tunnel is just so wide. Too much equipment can't fit in. Even if we bring in a few more boring machines, they still won't be able to fit in. If it collapses again,"
The working method of the excavation team is to excavate one section and reinforce another section. The collapsed sections were all tunnels that were just dug today and have not had time to be reinforced. If we act rashly, it is likely to lead to the extreme situation of digging and collapse at the same time.
"I don't care what method you use, just give me some time." Gao Kai said.
"Four to five hours at least."
"Don't worry about the tunnel, save people first!" Gao Kai was irritated, "Find a way to send oxygen in first, and do the rest slowly."
The excavation team leader nodded: "This is the only way to go first, but"
"This is so urgent. Why do you care so much? If you have anything to say, just say it!"
The excavation team leader made up his mind: "Director, you also know that the tunnel will be dug out soon. The team analyzed it a few days ago and found that the outer layer of the mountain is weathered and loose, and a landslide is likely to occur when the outer layer is dug."
"What on earth do you want to say?"
"I mean, could it be that the tunnel boring machine has already dug into the weathered surface?"
"What do you mean?" Gao Kai asked strangely.
When it comes to weathering, people who don’t know anything about it will instinctively associate rock weathering with wind. In fact, weathering has no direct relationship with wind. It is a very complex process of rocks, which can be roughly understood as physics, chemistry and biology.
Functions in several aspects.
For example, the thermal expansion and contraction caused by changes in cold and heat will cause the dissolution of minerals, the rooting and growth of plants, etc.
There is neither air nor liquid water on the moon, and there is no lush vegetation. No matter how you look at it, weathering and the moon are not related. They are two different things that cannot be compared with eight poles.
However, there are no absolutes. The lunar environment is a bit monotonous, but the moon has a huge temperature difference between day and night, and the surface is hit by high-energy particles and micrometeors all year round, which can also cause weathering of lunar rock formations.
Weathering means disintegration, alteration, and significant reduction in strength, so the excavation team concluded that a landslide may occur.
But does weathering or not have anything to do with rescue?
The excavation team leader made a small angle with his hand: "The outer edge of the crater is relatively thin, and the weathered layer is even thinner. What I mean is, can you see the collapse point from the outside? If you can see obvious collapse, excavation
There are definitely not many rocks on the plane. Can we cross over from the top of the mountain and carry out rescue directly from the outside?"
"Where did you come from with all this nonsense!" Gao Kai was furious, and the simple method was to make the excavation team leader say it was like a foot wrap.
He immediately shouted on the radio: "Communication Center, give me Ye Han's frequency!"
Although the astronauts on the moon all have military backgrounds, and most of them can play radio very well, there are always some who are not good enough.
Moreover, as there are more and more astronauts, the number of groups increases accordingly. Each group has its own communication frequency. No matter how good your memory is, it is impossible to write down all the communication frequencies, so the communication center responsible for the transfer came into being.
Beidou has not yet had the luxury to arrange a few astronauts to work as operators at the moon base. The communication center is actually on the earth. Its function is to provide communication frequencies for the astronauts. It is essentially equivalent to a manual directory inquiry station.
A few seconds later, Gao Kai received the data sent back from the earth, and the communication equipment automatically adjusted the communication frequency: "Call Ye Han, please answer after receiving it!"
"Ye Han received it, please tell me!"
"Help me check the satellite images. Is there any change at the south exit of the tunnel?" As the commander of the base, Gao Kai has the power to mobilize satellites.
But the only satellite receiving equipment in the base is the functional module that houses the power armor under the name of the military team. He has several ways to obtain satellite images. One is to apply directly to the ground, and the ground will control the lunar satellite. The other is to leave the construction site.
, personally enter the functional cabin of the military team. The third step is to directly contact Ye Han, who is responsible for monitoring the international base, and ask Ye Han to retrieve the images.
Ye Han must be in the military cabin at this time. The most convenient and effective method is obviously the third option.
Ye Han immediately retrieved the satellite image and zoomed in on the coordinate point of the south exit of the tunnel: "Lao Gao, the coordinate point has collapsed a little."
"Are you sure?"
"OK!" Ye Han continued to zoom in, "The image is very clear."
"Great!" Gao Kai was excited, "Ye Han, listen to me, I need you now!"
"I don't like men!" At this time, Ye Han didn't know that there was a landslide in the tunnel.
"I don't like to interrupt, let's get down to business." Gao Kai said with a serious look on his face, "The tunnel collapsed when it reached the exit, and a person was buried underneath. He still had two hours of energy left, and it was too late to dig out from inside.
You have to try it from outside, even if you give it some air."
Ye Han immediately became serious: "I understand, give me five minutes!"
