Yan Jiecheng told Lao Xie a few more words, and carefully explained some of the water inflow conditions in the construction of the new Austrian Law to Lao Xie again.

The new Austrian method itself is based on the premise of using the bearing efficiency of the surrounding rock itself. Millisecond blasting and smooth blasting technology are used to carry out full-section excavation construction.

The tunnel body is constructed by forming a composite inner and outer lining layers.

Because of the in-situ stress contained in the mountain, it is redistributed due to the excavation into a hole.

The tunnel space is stable by the cavitation effect, that is to say, the main bearing of in-situ stress is the surrounding rock mass itself, and the role of the initial spray anchor flexible support is to maximize the bearing capacity of the surrounding rock mass.

The second lining is mainly used for safety reserve and decorative beautification.

However, due to the development of geological surrounding rock joints, Dayao Mountain is mostly overlying sub-clay containing gravel, weakly weathered rock, fractured and developed, rich groundwater, poor self-stabilization ability, and the surrounding rock is easy to collapse.

Therefore, the risk of water inrush this time is very high.

Yan Jiecheng instructed him to always observe the amount of sediment at the water gushing point, and when a large amount of sediment gushed out, he must evacuate the equipment and people in advance.

After that, Yan Jiecheng began to walk towards the outside of the tunnel with difficulty.

More than an hour later, Yan Jiecheng and the others returned to the project headquarters.

Yan Xie Cheng arranged, and the accompanying technicians and the engineering personnel of the project department began to calculate the type and quantity of steel plates used for reinforcement.

In addition, the entire construction process of support and reinforcement was immediately studied.

He contacted urgently again, Ren Guogang, the leader of Guangdong. After all, he wanted to use steel plates to reinforce, but he was not familiar with these places. So I started asking this old acquaintance for help.

After Yan Jiecheng followed Ren Guogang for a few subtle sentences, he hurriedly got to the point.

The difficulties encountered in the Dayao Mountain Tunnel Project were briefly told to Ren Guogang.

Then he asked him where there was a steel mill nearby. Ren Guogang listened to Yan Jiecheng's requirements for steel.

After thinking for a while, he said: "Chief Engineer Yan, if the strength of the steel is very high, the ordinary small factory will definitely not meet the standard."

There will be no such fast production speed, and there is no ability to produce it in a short time.

The closest to us, the only one that meets the requirements is Liugang Iron and Steel Plant. ”

Yan Jiecheng was also relieved when he heard that it was Liu Gang. This Liuzhou just happens to have a branch of their road bureau here, and it is convenient to transport.

After all, it is a steel plant, and it must be connected by rail.

After getting the news from Ren Guogang, Yan Jiecheng hurriedly called the ministry's office.

Let them help find out Liu Gang's contact information.

At about four o'clock in the afternoon, Yan Jiecheng directly called the office of the director of Liugang Iron and Steel Plant.

"Director Shang, hello, I'm Yan Jiecheng, the chief engineer of the railway."

In the office of the director of the Liuzhou factory, the factory director Shang Wenlong listened to the voice on the phone with some confusion.

He didn't know who this so-called Yan Jiecheng was, what was the matter with him?

In recent years, the number of township enterprises has gradually increased, and all of them are like liars, and they want to make some steel here.

Therefore, Director Shang didn't think much about it, and said directly into the phone: "Hmm, how many times have I told you, we don't have extra steel here."

This steel is produced in accordance with the tasks of the state, and even if there is more, it is impossible for me to sell it to these township enterprises. ”

After saying that, he hung up the phone directly.

Yan Jiecheng on the other side of the phone looked directly confused.

This is still the director of the factory, who is the general who is so fierce?

Yan Jiecheng didn't give up again, and called twice again. As soon as the other party heard his voice, they all hung up directly.

Yan Jiecheng didn't care about getting angry, thought about it for a while, and then called the person in charge of the Liuzhou Road Bureau.

"Director Shao, I'm Yan Jiecheng. I am currently at the headquarters of the Dayao Mountain Tunnel Project, and now I order you to go to the Liugang Iron and Steel Plant immediately and call me back in their factory director's office. ”

Director Shao had just met with Yan Jiecheng at the opening ceremony of the bridge yesterday, but he didn't expect Yan Jiecheng to call him today.

Hearing Yan Jiecheng's order, he hurriedly said loudly: "Yes, leader." I'm going right now. ”

A few years after this Director Shao changed jobs, he heard Yan Jiecheng's order, put down the phone and called the driver, and immediately set off towards Liuzhou Steel Mill.

After many years of military career, he did not have any doubts and doubts about Yan Jiecheng's orders, but chose to carry them out thoroughly.

About half an hour later, Yan Jiecheng's phone rang.

Yan Jiecheng picked up the phone and said, "It's me." ”

"Report leader, I am now reporting to you in the office of the director of Liuzhou Steel Mill."

Yan Jiecheng listened to Director Shao's voice, and said gently: "Director Shao, thank you for your hard work. You first hand over the phone to Director Shao of Liugang Plant, I have something to look for him here. ”

A moment later, Yan Jiecheng heard a voice on the phone.

"Leader, I'm Liu Gang Shang Wenlong."

Yan Jiecheng said: "Director Shang, I finally got through to your call. ”

Director Shang hurriedly said: "Leader, I didn't know it was you before, I thought it was ......."

Yan Jiecheng ignored this and said directly: "What are you talking about? We'll talk about that when we're done.

I called you to confirm that your factory can produce 12MnV steel plates with a thickness of more than five cm? ”

After listening to Yan Jiecheng's question, Director Shao did not immediately give a result. Instead, he said, "Leader, wait a minute. I'll ask about the technical department of our factory. ”

When Yan Jiecheng heard the phone, he didn't say anything, just hummed twice. Then he said, "Okay, I'll wait for your call in a moment." ”

After Yan Jiecheng finished speaking, he hung up the phone directly.

In fact, Shang Wenlong, the director of this Liugang Plant, it will not be clear who this Yan Jiecheng is.

It's just that he is very familiar with Director Shao, after all, the materials in and out of the steel mill rely on the railway, and there is a lot of intersection between the two.

So when he asked Director Shao to call, he was very serious, and he knew that this Yan Jiecheng was not a simple person.

This will hang up the phone, and Director Shang is ready to ask Director Shao what is going on first.

Director Shao knew what he was thinking when he saw his demeanor, so he hurriedly said: "Lao Shang, you better quickly inform the relevant person in charge of your technical department to come here, and I will explain to you later." ”

When Director Shang heard what the other party said, he didn't ask much, and directly picked up the phone and called the technical department.

Making a phone call, Director Shang looked at Director Shao this time.

Seeing that he was so impatient, Director Shao said with a smile: "Lao Shang, you are also enough, and you directly hung up the phone of our Chief Engineer Yan a few times." ”

"Lao Shao, you don't laugh at people here, tell me who this person is? It's the first time I've seen you call, and you're so respectful and careful. ”

Seeing this, Director Shao said with a cautious face: "The person who is talking to you is the chief engineer of our department, and the third-ranked leader of our department's committee. ”

Director Shang looked at Director Shao dumbfounded, and said after a while: "Good guy, I thought it was the chief engineer of your General Bureau, but I didn't expect it to be a person who has passed through the sky." ”

Director Shao didn't speak, but replied with his eyes, otherwise what do you think.

Director Shang felt like a dream, he didn't expect that he would be so awesome one day, and hung up the other party three times.

Thinking of this, he smiled bitterly and said to Director Shao: "Old Shao, you have to save me." ”

Director Shao looked at the other party and said with a smile: "Don't worry, as long as you do a good job in the task assigned by Chief Engineer Yan this time, maybe the leader will give you a few good words, and maybe you will be blessed by misfortune when the time comes."

Besides, how can the leader be as careful as you think. ”

While the two were talking, there was a knock on the door. Director Shang didn't care about anything else, so he got up and walked quickly to the door and opened the door.

said: "Okay, well, you guys come in quickly." ”

As soon as a few people entered the office, Director Shang immediately asked: "Can our factory produce 12MnV steel plates with a thickness of more than five centimeters?" ”

Several people glanced at each other, and then said: "Factory director, our factory can produce this kind of steel." ”

Director Shang said happily when he heard this: "Okay, good." ”

After speaking, he quickly picked up the phone and called.

Yan Jiecheng, who was at the headquarters of the Dayaoshan Tunnel Project, heard the phone ringing on the table, so he hurriedly picked it up.

I only heard the phone say: "Leader, our factory can produce." ”

When Yan Jiecheng heard this, he was also overjoyed. Then he said: "Okay, the hard work is still the factory director, where are the technicians of your factory?" Let me tell you about the detailed technical parameters. ”

When the director of the factory heard this, he hurriedly said: "Okay, good leader, I will call the technicians of our factory." ”

Yan Jiecheng and the technicians of Liugang Iron and Steel Plant carefully told each other about the type, specification and size of the steel plate they needed.

The other party listened to Yan Jiecheng's words and said that their factory is fully capable of producing this kind of product.

Then, Yan Jiecheng asked the other party about the time again.

The other party promised that he could complete Yan Jiecheng's request before ten o'clock tomorrow morning.

After saying the product requirements, Yan Jiecheng talked to Director Shang.

"Director Shang is bothering you this time, I have to work hard tonight for you to hurry up production. We will bear all the costs this time, and we will not make it difficult for you.

Our ministry will also send a letter of appreciation to the industrial sector in your place to thank you for your strong support. ”

Yan Jiecheng gave Director Shang a date and painted a cake. Only then did he hand over the phone to Director Shao.

When the phone arrived in the hands of Director Shao, Yan Xie Cheng said solemnly: "You immediately organize engineering vehicles to Liugang Plant, and you can load as much as they produce, and you have to load the vehicles while producing."

By two o'clock tomorrow afternoon, all the steel must be transported to the Dayao Mountain Tunnel Project Headquarters.

I'll say hello to the general dispatch office in the ministry in a moment, and they will cooperate with you to provide some convenience. ”

After listening to Yan Jiecheng's words, Director Shao hurriedly said: "Leader, the Liuzhou Bureau guarantees to complete the task."

It must be delivered to the Dayao Mountain Tunnel Project Headquarters on time before two o'clock in the afternoon tomorrow. ”

On the side of the headquarters, Yan Jiecheng called the general adjustment room of the ministry again and told the other party about the situation. Let them actively cooperate and assist the Liuzhou Bureau to complete the transportation of emergency materials.

After arranging these tasks, Yan Jiecheng immediately began to study the construction process needed for this rescue with the technicians.

After all, the rescue time is tight and cannot be delayed. As soon as the steel plate for reinforcement arrives, the construction of the rescue point that must be transported immediately will begin.

Therefore, the entire construction process must be completed before this.

At night, the headquarters is brightly lit, and people come and go from time to time.

In addition to the rescue points in the tunnel, the personnel who transport materials from time to time.

Yan Jiecheng and they were still urgently preparing a plan in the room.

Every three hours, a group of people who were soaked all over their bodies withdrew from the rescue point, and the rest of the people came up again.

Yan Jiecheng looked out the window, and batches of personnel were replaced, and he couldn't help but worry about Lao Xie in his heart.

This can be replaced by others, but he, the commander-in-chief, has been in those sides for more than thirty hours, and this body doesn't know if he can resist it.

After all, a man who is already sixty years old.

The construction process of rescue support and reinforcement of water gushing points has been basically completed.

There are detailed regulations for the opening of the steel ring to the joint seam to the surface treatment of the steel plate ring.

As well as the preparation work in the tunnel has also been stipulated, the erection of scaffolding, the removal of running rails, feng shui pipes, high-voltage wires, lighting wire protection, the installation of machinery, materials, and personnel have been explained and specified in detail under the guidance of Yan Jiecheng.

The preparation of the installation of the steel ring, the setting of the lifting point of the steel ring, the position of the construction anchor bolt, the cleaning of the joint surface, the hoisting of the steel pipe segment, the welding of the steel pipe segment, the joint of the steel pipe segment, the grouting reinforcement of the steel ring, and the anti-corrosion treatment of the steel ring surface are required by Yan Jiecheng in accordance with the memory of later generations.

Seeing that the plan was completed, Yan Jiecheng could no longer stay in the headquarters.

At two o'clock in the morning, with a new batch of shift workers, I went to the water gushing place in the tunnel.

When he came here again, Lao Xie's face was very pale, and he was exhausted to the limit, and he was holding on with a ruthless spirit.

Lao Xie saw that Yan Xie Cheng was here again, and said in a hoarse voice, "Why are you here?" ”

Yan Jiecheng said: "I have prepared the reinforcement plan, and the reinforced steel plate has also been contacted, and it will be delivered here at two o'clock in the afternoon tomorrow."

It's not that I'm worried about you, so that's why I hurried over. ”

Lao Xie heard that Yan Jiecheng had already arranged everything. Immediately, I felt like a stone had gone to my heart.

Yan Xie Cheng saw what he was going to say, so he hurriedly said, "Old Xie, you have been here for almost two days and two nights, and you can't go on like this."

I'll watch it for you, and you hurry over and take a break. Tomorrow afternoon, when we carry out support blocking, we still need you to command. ”

"No, I can still hold on, I can't get out of here."

Yan Jiecheng waved his hand to a few people in the distance, and when several people saw Yan Jiecheng waving his hand, they hurriedly walked over.

Yan Jiecheng said to a few people: "Hurry up and pull your commander-in-chief Xie out and let him rest well." ”

"Don't mess around, I'm the commander-in-chief of this project, how can I leave if this happens?"

"Lao Xie, you listen to me and go to rest. Or do you believe it or not? Lao Tzu immediately got rid of you, the commander-in-chief. ”

Then, Yan Xie Cheng turned his head to look at the others and said, "What are you still doing in a daze?" Pull this old man out of here. ”
