The uncle on duty found Li Yu who was doing his morning jog.
Li Yu wiped off his sweat and let Xiao Jun and others come in wearing his undershirt.
Xiao Jun simply said to Li Yu directly: "Mr. Li, we are going to the steel plant today. There is something we need your support for."
"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 many zombies at the steel plant. We would like to borrow a drone to attract the zombies out."
Drone?
When Li Yu heard this, he suddenly understood.
Li Yu initially hoarded some drones, and later after the apocalypse broke out, he also collected many more. Among them were some large drones.
Therefore, there is no shortage of drones in current bases. Basically, everyone who goes out to perform tasks will be equipped with a drone.
Their personnel on duty will also regularly use drones to fly around the base to monitor the situation.
Li Yu waved his hand and said, "Okay, and do you still have enough bullets?"
Speaking of this, Xiao Jun looked a little embarrassed and said:
"There used to be some stock, but after coming from Orange Island, there isn't much left now."
After hearing this, Li Yu thought for a while and said:
"I will give you 1,500 rounds to support your operation. If more are consumed by then, I will replenish them for you."
Bullets, in addition to food and weapons, are one of the most important in the apocalypse.
Without bullets, a firearm is just a fire stick, even worse than a cold weapon.
At least the cold weapons are still relatively sharp.
Xiao Jun said with some gratitude: "Thank you, Mr. Li, leave it to us this time. I 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 will we set off?"
Li Yu didn't know how prepared He Chao and the others were. He saw them refueling the truck last night.
So he took the walkie-talkie and called He Chao over.
He Chao was well-equipped and looked ready.
Li Yu asked: "When do you plan to leave today?"
When He Chao saw Xiao Jun coming, he said with some embarrassment: "Right away."
Then he said to Xiao Jun: "I'm so sorry that I didn't have time to tell you about today's time yesterday. I'm really sorry."
Xiao Jun waved his hand and said it didn't matter: "We are all ready and can leave at any time."
He Chao became even more embarrassed when he heard this, patted his head and said:
"It's all my fault. I was too busy yesterday with some construction materials matters. Company Commander Xiao, we'll come over and join you right away."
Xiao Jun nodded, said a few words to Li Yu, and then returned to the small courtyard on the rural road.
Li Yu looked at He Chao, who was a little tired, and thought about the building materials needed in the base recently. He Chao was helping to deal with them. Not only did he have to distribute the building materials needed to non-staff members, he also had to lead a team to find them.
.
So he said: "You have been working hard recently, so let's let Li Hang handle the work arranged by the non-staff staff for the time being.
For the time being, you should focus on collecting supplies. After this period of work is over, I will give you a holiday."
He Chao scratched his head and said: "It's okay, I'm not busy alone. As for the non-staff, I will contact Li Hang."
Li Yu nodded.
He Chao then left.
Now in the base, the second uncle is mainly responsible for the internal operation and management of the base, as well as connecting with external cooperation teams.
The uncle is responsible for the security of the base, and also patrols around the base at intervals.
Seeing that Li Hang has become much more stable recently, Li Yu plans to train Li Hang, give him some more responsibilities, and practice his management and communication skills in a position that does not have such high risks.
Lao Lu took a few people to find Li Yu. Li Yu also talked to Lao Lu about the drone requirement he had raised with Xiao Jun, and asked him to take it with him when he went out later.
He found Li Yuan again and asked her to approve 1,500 rounds of ammunition and give them to Lao Lu, and then give them to Xiao Jun when they go out.
Fortunately, the bullets they used were all of the same caliber, so there was no own-shot incident.
Before leaving, Li Yu took Lao Lu, He Chao and others and sent them outside Xiao Jun's small courtyard.
And, according to this operation, it was pointed out in whose hands the leadership lies.
Both He Chao and Xiao Jun expressed their willingness to obey Lao Lu's orders in this operation.
This made Li Yu feel relieved a lot.
The most important thing for a team is to have clear leadership. Otherwise, when performing tasks outside, once several different opinions arise, it will not only delay the battle, but more importantly, in this crisis-ridden apocalypse, it is easy to lose manpower.
.
Otherwise, the entire army may be wiped out.
After all, Lao Lu had served as captain of the armed police brigade in a prefecture-level city 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.
Therefore, he also has leadership and management experience.
Xiao Jun naturally also knows that although he is the main staff, he has just joined, and it is still a cooperative relationship, so it is normal that he does not occupy the leadership position.
This Lao Lu seems to be a very capable person, and he should not issue some wrong orders.
After explaining all this, Li Yu returned to the base.
Just as they returned, they received news from Ding Jiu that the cave they were digging had collapsed.
Li Yu was in a hurry and rushed directly to the other side of the mountain without stopping in Wengcheng.
"Is anyone injured?" Li Yu came over and saw people coming out of the cave one after another, and asked Ding Jiu.
After hearing Li Yu's first concern and asking if the personnel were injured, Ding Jiu replied: "No, it's just that Wangcheng retreated a little too slowly and hurt his foot."
Seeing Ding Jiu pointing in the direction, Li Yu saw doctor Meng Yu bandaging a person's wound.
He walked over, looked at Wang Cheng's wounds, and asked, "Is the injury serious?"
While Mengyu was bandaging, when she saw it was Li Yu, she replied:
"It's not a big problem. My ankle was hit and it's swollen. In addition, there's a cut on the skin and it's a trauma. It will heal in a week and there will be no sequelae."
"That's good." Li Yu breathed a sigh of relief.
Then he said to Wang Cheng: "You should recover from your injuries for the time being."
Wang Cheng smiled and said, "It's okay. I walked too slowly just now, otherwise I wouldn't have been injured."
Li Yu nodded and said a few more words of concern.
Wang Cheng said he wanted to come over to help. He felt that the injury was not a big problem. After Li Yu tried to persuade him to no avail, he asked him to temporarily go to the underground planting base to help.
After Wang Cheng left, Li Yu turned his head and looked at Ding Jiu and Xiao Qian.
His face looked a little ugly and he said, "What was the cause of the landslide?"
Seeing that Li Yu seemed to want accountability, Li's father, 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 hole 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 loosely bonded thin layer of surrounding rock and the axis of the cave was less than 45°, so a landslide occurred during the excavation."
Li Yu said nothing, took a flashlight, and walked into the cave.
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. Make sure it's safe and stable. If it's too difficult to dig 10 acres a month, then just 5 acres.
In short, the area is not considered the first principle 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 Xiao Qian nodded repeatedly, indicating that they would pay attention later.
This small landslide is something that happens occasionally during cave excavation and is considered normal.
But Li Yu was very concerned about stability and safety, so he asked about the safety protection and asked them to configure it according to the requirements.
Don't save cement or construction materials. You must ensure that even if there is an earthquake or a cannonball hits it, it will not collapse.
After knowing Li Yu's standards, Xiao Qian was a little stunned and said: "Then the materials needed will be several times the original ones."
Li Yu said seriously: "If you use it, you must ensure its stability."
After speaking, he reminded himself that he must come here more often in the future.
After explaining all this, Li Yu asked Ding Jiu:
"Uncle Ding, I hope 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 in a short amount of time or in advance, and to clear the slag in sections;
After the inspection is completed, the steel mesh should be laid out in a timely manner, gratings or arch supports should be installed, concrete should be sprayed, anchors should be installed, and the initial support of the tunnel after slag removal should be completed in a timely manner;
Once these are done, landslides will basically be less likely to occur.
I was still in a rush for time, so I was a little anxious and didn't get some homework done.
In addition, I think that in the following excavation operations,
Try to use construction methods of shallow drilling, weak blasting, strong support, and frequent measurement to reduce disturbance to the surrounding rock;
Soft or extremely soft rocks should be excavated manually and with small excavators.
This way, nothing goes wrong.”
After all, Li Yu was not a professional, but he could hear the general meaning: reduce the blasting strength and increase the support strength.
He nodded and said:
"Try to be more prudent and prevent such landslides from happening again. Even if it is a small landslide, try not to have one.
I will arrange for someone to come over and help you. Where is Xu Zhen? He should be very professional when it comes to digging cave drainage problems."
Ding Jiu said:
"Xu Zhen is still in the cave, didn't you see him just now?
There isn’t much of a manpower problem, Lao Lu called some people over to help, as well as the workers who followed me before, and Song Min and the others are all here.”
Li Yu remembered the piece of cloth under the pillar in the corner of the cave, 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 that his face was dusty and dusty.
After a few words of encouragement, he said: "Xu Zhen, please cooperate with Ding Jiu and others to pay attention to the drainage and leakage issues."
Xu Zhen said there was no problem, and then took Li Yu to talk about some professional ideas on the cave wall.
Li Yu listened quietly.
After explaining to everyone that safety and stability were the first principles, Li Yu simply didn't leave and directly joined in to help.
At present, everything that should be arranged inside and outside the base has been arranged.
He Chao and Deng Ben also ordered him to go down, and Xincheng strengthened its protection and paid attention to the arrival of strangers.
Third uncle and Lao Qin are both at the base. If something happens, with uncle and the others there, there won't be any big problems.
In addition, Lao Qin took his brothers, Li Tie, Lao Luo and others who 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 do the work.
Therefore, when digging caves, safety and stability are required.
But at the specific implementation level, he did not interfere. Instead, he 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 the explanations given by Ding Jiu and others, Li Yu learned some basic knowledge about civil construction very quickly.
In addition, you have strong hands-on skills. After basically explaining it once and executing it once, you will know how to operate it and also understand some of the principles behind it.
These are some of the benefits that Li Yu has brought since his rebirth.
Not only did his physical fitness improve greatly, but his comprehension and thinking abilities also greatly improved.
However, for Li Yu, the biggest change since his rebirth is that he has strengthened his perception of danger.
This sixth sense that he had developed during the five years before his rebirth had strengthened several times after his rebirth.
