Apocalypse Rebirth: 3000 million won at the beginning

Chapter 553 Cave Collapse! (Add more, 510)
Big camphor tree base.

Just after dawn, Xiao Jun came under the wall.

The uncle on duty found Li Yu who was running in the morning.

Li Yu wiped off his sweat, and let Xiao Jun and the others in while wearing an undershirt.

Xiao Jun simply said to Li Yu directly: "President Li, we are going to the steel factory today, and we need your support for something."

"What's the matter?" Li Yu raised his head and asked.

Xiao Jun looked at Li Yu and said:

"I heard from He Chao that there are a lot of zombies at the steel plant. We want to borrow the drone so that we can attract the zombies out."

Drone?
When Li Yu heard this, he immediately understood.

At the beginning, Li Yu hoarded some drones, and later after the outbreak of the end of the world, he also collected a lot.Among them are some large drones.

Therefore, there is no shortage of drones in the current base, and those who basically go out to perform missions will be equipped with a drone.

Also, their staff on duty will regularly use drones to fly around the base to investigate the situation.

Li Yu waved his hand and said, "Yes, and do you still have enough bullets?"

Speaking of this, Xiao Jun was a little embarrassed, and said:
"There were still some stocks in the past, but after coming from Juzizhou, there are not many left now."

Li Yu heard the words, thought for a while, and said:
"I will give you 1500 rounds to support your operation. If you consume more by then, I will replenish them for you."

Bullets, in the last days, besides food and weapons, are one of the most important.

Without bullets, a firearm is just a stick of fire, even worse than a cold weapon.

At least cold weapons are sharper.

Xiao Jun said gratefully: "Thank you Mr. Li, leave it to us this time, we promise to get it done."

Li Yu said with a smile: "I believe you. Okay, is there anything else?"

Xiao Jun thought for a while and asked, "When are you leaving?"

Li Yu didn't know how He Chao and the others were preparing. He saw them refueling the truck last night.

So he took the walkie-talkie and called He Chao over.

He Chao is travel-laden, fully equipped, and looks ready.

Li Yu asked, "When are you planning to leave today?"

Seeing Xiao Jun approaching, He Chao said with some embarrassment: "Right away."

Then he said to Xiao Jun: "I'm really sorry, I didn't come to tell you today's time yesterday, I'm really sorry."

Xiao Jun waved his hand, saying that it doesn't matter: "We are all ready and can leave at any time."

He Chao felt even more embarrassed when he heard this, patted himself on the head, and said:

"It's all my fault. There were some building materials matters yesterday, and I was too busy to turn around. Company Commander Xiao, we will come over to meet you right away."

Xiao Jun nodded, said a few words to Li Yu, and then returned to the small courtyard on the township road.

Li Yu looked at He Chao, who was a little tired, and thought about the construction materials needed in the base recently. .

So he said: "You have worked hard recently, how about this, for the time being, let Li Hang take care of the work arranged by the non-staff personnel.

For the time being, you will focus on collecting supplies.After this busy period is over, I will give you a vacation. "

He Chao scratched his head and said, "It's okay, I'm not alone. I'll connect with Li Hang for the non-staff personnel."

Li Yu nodded.

Then He Chao left.

Now in the base, the second uncle is mainly responsible for the internal operation and management of the base, as well as the connection with the external cooperation team.

The uncle is responsible for the security of the base, and patrols around the base at intervals.

Seeing that Li Hang has become more stable recently, Li Yu plans to train Li Hang, give him a little more burden, and exercise his management and communication skills in a position that does not have such a big risk.

Lao Lu took a few people to find Li Yu, and Li Yu also talked to Lao Lu about the drone demand he and Xiao Jun had proposed, and asked him to take it with him when he went out later.

I found Li Yuan again and asked her to approve 1500 rounds of ammunition and hand them over to Lao Lu, and hand them over to Xiao Jun when they go out later.

Fortunately, the bullets they used were all the same caliber, and there was no own incident.

Before leaving, Li Yu took Lao Lu, He Chao and others, and sent them to Xiao Jun's small courtyard.

And, according to this action, it was indicated in whose hands the leadership was.

Both He Chao and Xiao Jun expressed their willingness to obey Lao Lu's orders in this operation.

This relieved Li Yu a lot.

The most important thing for a team is to have a clear leadership, otherwise when there are several different opinions when performing missions outside, it will delay the opportunity, not to mention, the important thing is that in this crisis-ridden end times, it is easy to lose manpower .

If it doesn't work out, the entire army may be wiped out.

After all, Lao Lu served as the captain of the armed police in prefecture-level cities before the end of the world. Later, when he was in Jiefang City, he was also responsible for leading the important work of the team.

So, he also has leadership and management experience.

Xiao Jun naturally also knows that although he is the main force, he has just joined after all, and it is still a cooperative relationship, so it is normal that he does not occupy the leadership position.

This old Lu seems to be quite a capable person, and he should not give some wrong orders.

After explaining all this, Li Yu returned to the base.

As soon as he returned, he received a message from Ding Jiu that the cave he was digging had collapsed.

Li Yu hurried, did not stop in the urn city, and went directly to the other side of the mountain.

"Is anyone injured?" Li Yu came over and asked Ding Jiu when he saw people coming out of the cave one after another.

Hearing Li Yu's first concern about whether the personnel were injured, Ding Jiu replied: "No, it's just that Wangcheng retreated a little slower and hit his foot."

Seeing Ding Jiu pointing in the direction, Li Yu saw the doctor Meng Yu bandaging a wound.

Walking over, looked at Wang Cheng's wound, and asked, "Is the injury serious?"

While bandaging, Mengyu saw that it was Li Yu, and replied:
"It's not a big problem. The ankle was smashed and swollen. In addition, the epidermis was opened and the skin was injured. It can be cured in a week without leaving any sequelae."

"That's good." Li Yu breathed a sigh of relief.

Then he said to Wang Cheng, "Take care of your injuries for the time being."

Wang Cheng said with a smile: "It's okay, I walked too slowly just now, otherwise I wouldn't be injured."

Li Yu nodded and said a few more words of concern.

Wang Cheng said that he would come over to help. He felt that the injury was not a big problem. After Li Yu persuaded him to no avail, he asked him to go to the underground planting base to help temporarily.

After Wang Cheng left, Li Yu turned to look at Ding Jiu and Xiao Qian.

His face was a little ugly, and he said, "What's the reason for the landslide?"

Seeing that Li Yu seemed to want to be held accountable, Father Li, who was also managing the excavation work, came over and said:

"I don't blame them. The main reason is that the construction period is too tight. Therefore, the excavation cycle footage is too large, which greatly disturbs the surrounding rock and reduces the self-supporting capacity of the surrounding rock.

In addition, the angle between the tunnel line and the main structural fracture surface and the direction of the weak zone is less than 30°, so landslides are prone to occur;
Moreover, the angle between the loose thin-layered surrounding rock and the hole axis is less than 45°, and a landslide occurred during the excavation just now. "

Li Yu didn't speak, and walked into the cave with a flashlight.

From yesterday to today, in just a few dozen hours, hundreds of square meters of space have been dug out of the cave.

Looking at the pillars on the cave, Li Yu thought for a while and said:

"Don't be too anxious, you must ensure safety and stability. If it is too difficult to dig 10 acres a month, then 5 acres.

In short, the area is not the first principle to consider for the time being. The first principle is safety and sufficient stability.The second is time, within a month, as much as can be excavated. "

Ding Jiu and engineer Xiaoqian nodded repeatedly, indicating that they would pay attention to it later.

The small landslide this time is also an occasional occurrence during the excavation of the cave, and it is also normal.

But Li Yu was very concerned about the stability and safety, so he asked again about the safety protection and asked them to configure it at the top level.

Don't save on cement, don't save on building materials.We must ensure that even if there is an earthquake, even if a shell hits it, it will not collapse.

After knowing Li Yu's standards, Xiaoqian was a little speechless and said: "Then such materials are needed, and the original amount is several times."

Li Yu said seriously: "Use it, you must ensure its stability."

After finishing speaking, he reminded himself that he must come here more often in the future.

After explaining all this, Li Yu asked Ding Jiu again:

"Uncle Ding, I hope that no one will be injured during the excavation. Do you have any good solutions to this landslide?"

Ding Jiu thought for a while and said:
"In fact, the most stable method is to grout the pipe shed with short footage or ahead of time, and carry out slag removal by division;

After the inspection is completed, timely lay out steel mesh, install grille or arch support, spray concrete, set anchor rods, and complete the initial support of the tunnel after slag removal in time;

After finishing these, it is basically not easy to cause landslides.

I was still in a hurry before, so I was a little anxious, and some homework was not done properly.

Also, I think that in the next excavation work,
The construction method of shallow drilling, weak blasting, strong support, and frequent measurement shall be adopted as much as possible to reduce disturbance to surrounding rock;

Soft rock or extremely soft rock should be excavated manually and with small excavators.

This way, nothing will go wrong. "

After all, Li Yu is not a professional, but he can hear the general meaning: reduce the blasting strength and increase the support strength.

He nodded and said:

"Try to be safe, and don't let such landslides happen again, even if it is a small landslide, try not to have it.

I will arrange people to come and help you, where is Xu Zhen?He should be very professional in excavating cave drainage. "

Ding Jiu said:
"Xu Zhen is still in the cave, didn't you see him just now?

There is no big problem with manpower. Lao Lu called some people to help, as well as the workers I used to follow me, and Song Min and the others were all there. "

Li Yu remembered the piece of cloth under the pillar in the corner of the cave just now, and then realized that it was a person, probably Xu Zhen.

Then he entered the cave again and saw that it was indeed Xu Zhen. After calling him over, he found his face was dusty and covered with dust.

After a few words of encouragement, he said: "Xu Zhen, you must cooperate with Ding Jiu and the others to pay attention to the problem of drainage and water leakage."

Xu Zhen said there was no problem, and then took Li Yu to the cave wall and said some professional thoughts.

Li Yu listened quietly.

After explaining to everyone, after putting safety and stability as the first principle, Li Yu didn't leave at all, and directly joined in to help.

Right now, inside and outside the base, everything that should be arranged has been arranged.

He Chao also ordered Deng Ben to go down there, and Xincheng strengthened its defenses and paid attention to the arrival of strangers.

The third uncle and Lao Qin are both at the base. If something happens, with the uncle and the others around, there won't be any major problems.

In addition, Lao Qin brought his brothers, and Li Tie and Lao Luo were familiar with the operation of tanks and armored vehicles.

Although Li Yu is the leader in the base, he understands that professional people should be handed over to professional people.

Therefore, on the side of excavating caves, although the requirements for safety and stability have been raised.

But at the specific execution level, he didn't intervene, but obediently followed Ding Jiu's orders.

Soon, Ding Jiu and the others discovered that Li Yu had a strong learning ability.

In just a short while, during Ding Jiu's explanation, Li Yu quickly learned some knowledge about civil construction.

In addition, the hands-on ability is very strong. After basically explaining it once, and executing it once, you can know how to operate, and also know some of the principles behind it.

These are some of the benefits that Li Yu has brought since his rebirth.

Not only has his physical fitness been greatly improved, but his comprehension ability and thinking ability have also been greatly improved.

However, for Li Yu, the biggest change since his rebirth is that his perception of danger has been strengthened.

This sixth sense, which he had cultivated during the five years of the apocalypse before his rebirth, was strengthened several times after his rebirth.
