Five Hundred Fifty Nine Landslides

The level of open and covert conflicts between countries is too high, and a small person like Ye Han can't touch that level at all. He and all the astronauts stationed on the moon focus on the construction of the base. update the fastest

With the gradual expansion of the No. 1 base, the food production gradually increased, and the number of astronauts sent to the moon also increased, further speeding up the construction of the base.

The tunnel construction site in early June.

There was a muffled bang, and the entire tunnel trembled. Countless huge boulders fell from the sky, and the collapsed tunnel crushed the laser boring machine under the pile of stones.

"It's a landslide, it's a landslide!" The construction team was in a mess and immediately reported the news.

After receiving the news, Gao Kai's head was as big as a bucket, and he was very depressed, but the first task right now is not to figure out the cause of the landslide, but to rescue people first!

He rushed to the construction site immediately: "How is the person? Have you made contact?"

The excavation team leader replied: "I got in touch, and I'm fine."

After the production capacity of the smelting group was formed, the shortage of metal materials was greatly alleviated. The roadheader, 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 also been replaced with tracks of the same material. It is better to say that it is a laser tunneling machine than a laser tunneling tank.

However, no matter how strong the protection is, it cannot withstand the pressure of hundreds of tons of rocks.

Gao Kai breathed a sigh of relief: "As long as people are fine, how long will it take?"

"Two hours." The excavation team leader said, "Xiao Zhou still has two hours of oxygen."

Gao Kai looked at the tunnel blocked by boulders: "How long has it collapsed?"

"More than twenty meters."

"Can you get through in two hours?"

The excavation team leader shook his head: "It's very difficult, and there may be another landslide at any time."

Gao Kai's temples throbbed violently: "Go all out, whether you need people or equipment, I'll send you over!" The landslide didn't happen sooner or later, but the landslide just in time for the tunnel to be completed, what's the matter?

"It's not about people and equipment." The excavation team leader shook his head. "The tunnel is only so wide. If there is too much equipment, it won't be able to fit in. Even if a few more boring machines are brought in, it won't be able to fit in. If it collapses again..."

The working method of the excavation team is to excavate a section and reinforce a section. The collapsed sections are tunnels that have just been dug today and have not had time to be reinforced. If they act rashly, it is very likely that there will be an extreme situation where the tunnel collapses while digging.

"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, "First find a way to send oxygen in, and do the rest slowly."

The excavation team leader nodded: "I can only do this first, but..."

"This is so imminent, what are you still trying to do? Just say something!"

The excavation team leader made up his mind: "Director, you also know that the tunnel will be dug through soon. The team analyzed a few days ago 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 do you want to say in the end?"

"I mean, could it be that the boring machine has dug into the weathered surface?"

"What do you mean?" Gao Kai asked strangely.

When it comes to weathering, people who don't know it will instinctively associate rock weathering with wind. In fact, weathering has nothing to do with wind directly, but a very complicated process of rocks, which can be roughly understood as physics, chemistry and biology. function in several ways.

For example, the thermal expansion and contraction caused by the change of cold and heat; the dissolution of minerals by water; the root growth of plants and so on.

There is neither air nor liquid water on the moon, let alone lush vegetation. No matter how you look at it, weathering and the moon are inseparable. They are two different things.

However, there is no absolute. The lunar environment is a bit monotonous, but the moon has a huge temperature difference between day and night. The surface is hit by high-energy particles and micro meteors all the year round, which can also cause weathering of the lunar rocks.

Weathering means disintegration, alteration, and a significant reduction in strength, so the excavation team made the inference that a landslide may occur.

But weathering or not, does it have anything to do with rescue?

The excavation team leader compared a small angle with his hands: "The outer edge of the crater is relatively thin, and the weathered layer is even thinner. I mean, can you look at the collapse point from the outside? If you can see the obvious collapse, excavation There are definitely not many rocks on the plane, can we go over the top of the mountain and start rescue directly from the outside..."

"Where are you talking so much nonsense!" Gao Kai was furious, and the simple way made the excavation team leader call it 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 second-handed knives who are not as good as they are.

Moreover, there are more and more astronauts, and the number of groups increases accordingly. Each group has its own communication frequency. No matter how good the memory is, it is impossible to write down all the communication frequencies, so the communication center responsible for switching came into being.

Beidu is not yet extravagant enough to arrange a few astronauts to work as operators on the moon base. The communication center is actually on the earth. Its function is to provide communication frequencies for 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 if you receive it!"

"Ye Han received it, please tell me!"

"Help me look at the satellite image, is there any change at the south exit of the tunnel!" As the commander of the base, Gao Kai himself has the power to mobilize the satellite.

But the only satellite receiving equipment in the base is the functional cabin for 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 controls the orbiting satellite; the other is to leave the construction The third is to directly contact Ye Han, who is in charge of monitoring the international base, and ask Ye Han to retrieve the images.

During this period of time, Ye Han must be in the military cabin. The most convenient and effective way is obviously the third item.

Ye Han immediately retrieved the satellite image and zoomed in on the coordinate point of the south exit of the tunnel: "Old Gao, the coordinate point has collapsed a bit."

"you sure?"

"Sure!" 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 it either...don't interrupt, let's talk about business." Gao Kai's face was dark, "The tunnel collapsed when it was dug to the exit, and a person was buried under it. He still had two hours of energy, and it was too late to dig through it. Now, we must try it from the outside, even if we send some air."

Ye Han immediately became serious: "Understood, give me five minutes!"
