The Boss of the Yan Family in Siheyuan

Chapter 172 Cherish Feather Yan Jiecheng

Seeing this situation, Professor Jin found Yan Jiecheng and explained the situation to Yan Jiecheng.

It turned out that the tunnel design drawings were not independently designed by Professor Jin and the others.

They also just perfected the old drawings.

In Professor Jin's detailed explanation, Yan Jiecheng realized that in October 1956, Mao Xiong sent experts to help us build the subway.

The bear experts who came to the capital at that time were all experts involved in the construction of the Moscow subway and had rich practical experience.

As soon as they arrived in the capital, they began to devote themselves to the construction of the subway.

First of all, they spent a lot of time investigating, measuring and surveying the terrain of BJ.

Determine where the subway can be built, determine the route of the subway, and how to connect the new city with the old city.

In addition, the subway is underground after all, and higher safety must be considered to prevent collapse.

Therefore, strict planning has been carried out for the depth of the subway construction, the choice of tunnels, and the structure.

Moreover, the underground structure is complex and changeable, such as sewers, groundwater systems, loose soil, etc. These are all factors that need to be considered in the construction of subways.

With the help of Mao Xiong experts, after a long period of investigation and survey, finally in 1958, the Railway General Metro Engineering Bureau was formally established, ready to start the construction of the subway.

Unfortunately, the good times don't last long.

In those three years, due to serious mistakes and large-scale natural disasters, the country fell into a serious economic disaster.

It is said that food is the most important thing for the people, and only by filling their stomachs can they have the strength to work, not to mention the huge cost and labor-intensive subway construction work.

Therefore, the construction of the subway had to be temporarily suspended.

Until last year, the economy has gradually eased, and the country has passed the most difficult time.

For transportation, military defense.Therefore, the project was restarted and the construction of the unfinished subway continued.

After listening to Professor Jin's words, Yan Jiecheng understood why these people questioned him.

Domestic technology is backward these days, and they all learn from the teacher Mao Xiong.

Yan Xiecheng actually said that there was something wrong with the tunnel blueprints designed by Mao Xiong, so it was definitely Yan Xiecheng who made a mistake.

It can't be that Mr. Bear is wrong, right?
Yan Jiecheng also understood this very well.

At the same time, he also knows that if his own judgment is correct, it means that all the more than 3 drawings related to the structure will have to be revised.

This is brutal for technicians who have been fighting for a long time.

However, science must not be sloppy.

Yan Xie became to prove that his theory was correct.

They applied for several trucks from the headquarters and pulled everyone from the tunnel design office to the first three canals under construction.

Just when everyone was puzzled, Yan Jiecheng conducted an experiment.

The cross section of this canal is a straight line cross section.Yan Xiecheng made a projection of these sections and projected them on the plane.

The technicians at the tunnel design office can easily see that the projections differ by [-] to [-] centimeters.

After Yan Jiecheng's experiment, these people were so surprised that they couldn't help themselves.

It never occurred to them that the bear expert would make a mistake.

The facts were right in front of them, and they had to agree with Yan Jiecheng's theory.

I had no choice but to get up and change the picture quickly.

After three months of hard work, all 3 drawings have been corrected, and the original planned start date has naturally been delayed.

Fortunately, the higher authorities allowed mistakes and did not pursue the responsibility of the tunnel design office.

This subway is a war preparation project, and Yan Jiecheng didn't dare to delay it for a day. He organized people to review the revised map and then reported the situation to the commander in chief.

The commander-in-chief directly called the heads of several construction units on the spot and announced the start of construction.

As for the review of the construction unit's drawings, according to the commander-in-chief's intention, let them review while constructing.

The construction units are mainly the No.12 Division of the Railway Corps, the Metro Engineering Bureau, and the Beijing Urban Construction Bureau.

None of them raised any objections, and naturally the real construction began.

After all, it's nothing to them.They often encounter that kind of three-sided project, so it is not a big deal.

As the chief designer, Yan Jiecheng is too aware of how perverted this subway is.

This thing really cannot be called a subway, it is simply an underground fortress, with all kinds of dark rooms underground.

The subway is designed according to the highest standard of three defenses, which can prevent atomic radiation, chemical and bacteria.

For every door underground, the sealing material used is the same as that of a submarine.

This line also connects the Xishan garrison station and the Beijing Railway Station.

Troops can be transported quickly.

Yan Jiecheng secretly calculated that the built subway in the capital could transport the troops of 5 army reorganized divisions from Xishan to the urban area every day during the war.

Thinking of these, Yan Jiecheng was shocked.

What's the point of killing yourself?
Although I am the chief designer, I know almost everything I should know.

But it's best not to know about this terrible thing.

However, Yan Jiecheng also knew that it would take several years for this project to be partially declassified.

The information I know is going to be completely rotten in my heart.

In the future, it will be changed, and Yan Xiecheng will probably be restricted from leaving the country.

Even if there were no restrictions, Yan Jiecheng wouldn't dare to go out. After going out, he would definitely be missed by many people.

I don't know if I can come back!
With the completion of the review of the drawings, the capital subway quietly started full-scale construction.

Because the tunnel is buried shallowly, open cut and cut construction is adopted for the on-site construction, and then buried after construction is completed.

After the design of the main structure was completed, Yan Xiecheng focused on electromechanical, electric power, communication, signal, and interior decoration.

Of course, he also needs to communicate with the tunnel construction unit at any time to understand their on-site construction situation.

In addition to the necessary staff in the Tunnel Design Department of the Design Department, everyone else asked him to transfer to the construction site.

Yan Jiecheng thought that the work would be easier after the design was completed.

Turns out it's even busier now.

Especially the professionally designed solutions such as electromechanical, which made a large number of domestic manufacturers very desperate.

Everyone shouted: The concubine can't do it.

Yan Jiecheng communicates with these factories every day to negotiate and solve these technical problems.

These problems are really troublesome, such as installing a vertical ladder in a limited underground space, but the motor provided by the manufacturer is too large and there is no place to install it.

This requires him to contact a new cooperation unit, or ask the original factory to step up technology research and development, and make a special motor suitable for their project.

These days, Chang Kexin is already pregnant.

The third mother is worried about her daughter-in-law, or maybe the child in her belly.

After cooking for the family in the afternoon, she would go to the courtyard to cook for Chang Kexin and Yan Jiedi.

As for Yan Jiecheng, every time he came home he was very late.

It is difficult to take care of my daughter-in-law.

Although he felt ashamed, there was nothing he could do.

On this day, Yan Jiecheng went on a business trip with comrades related to civil air defense facilities to visit the No. [-] Steel Rolling Plant in Beijing.

Their project needs waterproof, fireproof, anti-virus, and anti-smoke doors, which need to be produced near the capital.

Therefore, everyone brought the drawings and came to the rolling mill to assign tasks.

The capital subway is a key armament project, and all factories in the capital need to cooperate.

This departure, of course, was driven by a driver sent by the headquarters.

Sitting in the car, Yan Xiecheng looked at the environment around the rolling mill, feeling a lot of emotion in his heart.

When the car arrived at the gate of the rolling mill, the guard was still that Uncle Yang.

Seeing the car approaching, the old man hurried out of the duty room when the driver stopped the car and was about to negotiate.

Yan Jiecheng said, "Xiao Wu, let me go and talk to him."

After Yan Jiecheng finished speaking, he opened the car door and got out.

Turning to Old Man Yang, he said, "Uncle Yang, it's me, Yan Jiecheng."

As he spoke, he took out a cigarette and handed one to the other party.

When the old man saw Yan Jiecheng taking out his cigarette, he immediately remembered it.After all, he had been guarding the door for so many years, and it was up to Yan Jiecheng to take out the cigarette.

The action of buttoning the button is too deep in my memory.

Old man Yang took Yan Jiecheng's cigarette and said with a smile, "It's you, I heard they say you've become a cadre."

When Yan Jiecheng saw the old man, he also felt very kind.

He also lit a cigarette for himself, and said with a smile; "It's all about serving the people."

The old man laughed when he heard this.

He could tell that Yan Jiecheng's tone was sincere even though his smile was not serious.

At this time, Director Yang of the rolling mill arrived at the door.

When he came here earlier, Yan Jiecheng had already called the rolling mill, so Director Yang had already asked the security department to pay attention to the situation at the door.

So when I got the news, I hurried out.

When Lao Yuan saw Yan Jiecheng, he shouted: "Minister Yan, Minister Yan, you are welcome to come back and guide the work."

Seeing Director Yang's enthusiasm, Yan Jiecheng went up to meet him and said, "Director Yang, you are my old leader. You are here today to return to your mother's house, so you don't dare to offend me."

After talking, the two of them shook hands enthusiastically.

Everyone went to the factory together.

When he arrived at the meeting room, Yan Jiecheng saw that the director Yang and secretary Yang were both there.

So he asked his fellow driver Xiao Wu to act as a guard and guard the door.

Seeing Director Yang and the others' expressions change, Yan Jiecheng said, "Director Yang, you should know why we are here."

Director Yang said: "Today the bureau has notified us, let us do our best to cooperate with the superior department."

Factory Director Yang actually knew very little. Today, the leader of the Municipal Bureau only told him that the person who came was Director Yan, and that it was enough for him to cooperate. Don't ask too many questions.

Therefore, he did not know the specific situation of Yan Xiecheng and the specific purpose of coming here.

The Yan Xiecheng he knew was still the director of the Tiezong cadre training academy.

Seeing this, Yan Jiecheng motioned to the accompanying technicians.

That comrade, seeing Yan Xiecheng's gesture, took out a document from his bag and handed it to Director Yang.

After reading it, Factory Manager Yang handed it to Secretary Yang on the side.

Seeing the two of them read it, they both clearly knew the value of this document.

Knowing this, they must actively cooperate, so they all became very serious.

Only then did Yan Jiecheng say: "Since the two of you have understood the situation, let me tell you about our requirements."

Afterwards, Yan Jiecheng asked the accompanying technicians to give the blueprint of the civil air defense door to Director Yang, and explained the requirements to the two of them.

However, these two are not professionals and do not know much about technology.

Therefore, this technical clarification stopped.

Factory Manager Yang apologized to Yan Jiecheng and the others, and asked Secretary Yang to accompany them.

I hurried to organize a reliable technical team to complete the technical disclosure work.

Factory Manager Yang is still very capable of handling affairs. After half an hour, he organized a technical team and brought them to the conference room.

Yan Jiecheng was surprised to see Yi Zhonghai in the technical team of the rolling mill.

But thinking about it, it was normal for Yi Zhonghai, as a newly promoted eighth-level fitter in the rolling mill, to participate in it.

Yi Zhonghai was also taken aback when he saw Yan Jiecheng sitting in the chief seat.

As an eighth-level fitter, he walks with his head up in the factory.

He considers himself successful.

But seeing Yan Xiecheng, who was sitting on the main seat, looking at them with scrutiny, his heart felt like a discouraged ball, and he followed everyone to their seats honestly.

"Leaders, this is the technical backbone of our factory, and we can continue to disclose the technology."

Yan Xiecheng nodded, and the technicians on the side immediately talked to the people in the rolling mill about the size, thickness, steel type, steel plate strength, and workmanship requirements of the air defense door.

These technicians and some old masters in the rolling mill couldn't help being speechless after hearing the request.

This is so demanding!
Yan Jiecheng looked at these people carefully, seeing that their expressions were normal, presumably there were no enemy agents.

Yan Jiecheng believed that Director Yang knew what he was looking for, and he was looking for employees with a clean background.

In fact, it doesn't matter even if there are enemy agents.

After all, these people's defense doors are just some iron doors. What can you do if you know it?
After the confession, Yan Xiecheng and the others still hadn't left. They were waiting for an internal meeting in the rolling mill to discuss the results.

If Director Yang can't take over the job, Yan Xiecheng and the others will have to go to another rolling mill.

About half an hour later, Factory Manager Yang quickly walked to the conference room where Yan Jiecheng and the others were resting.

Said: "I'm sorry to keep Yan Department waiting for a long time. Just now our factory technicians have demonstrated that this batch of civil air defense doors can be made in our factory."

After hearing this, Yan Jiecheng smiled and said, "Then I will trouble you."

Yan Jiecheng turned his head to look at the colleagues who came together, and said with a smile: "Since the matter of the guarded door has been settled, let's go, and don't disturb Director Yang and his work."

After hearing Yan Jiecheng's words, several people got up one after another, ready to leave.

Factory Manager Yang saw him, and hurriedly said: "Minister Yan, leaders, you see, it's time for lunch, and all leaders will miss the meal when they go back. Why don't you just make do with it in our factory."

What Director Yang said is also reasonable. It is indeed time for dinner, and there should be no dinner when we go back to the headquarters.

So everyone turned to Yan Jiecheng. After all, he was the leader, and he still had to decide on this matter.

Yan Jiecheng looked at his watch, saw the faces of several people, and said, "That's troublesome."

Director Yang said happily: "No trouble, it's just a trivial matter."

Although Yan Xiecheng decided to have lunch at the rolling mill, he still couldn't save the necessary procedures.

Immediately, he took out some money tickets, handed them to Director Yang and said, "This is our food coupon and food expenses at noon, please accept it from Director Yang."

Lao Yang likes to attract people with food from the cafeteria, how could he accept it.

Yan Jiecheng finally said, if you don't accept the food stamps and money, we won't eat, and then Factory Manager Yang accepted it.

Now that Yan Jiecheng looks forward to his official career, he also knows how to cherish feathers, how could he still be greedy for such petty gains like before.

Factory Manager Yang collected the things and went to arrange lunch.

Seeing that Yan Xiecheng had handed out the money ticket for them, several people hurriedly said, "Mr. Yan, this is my money ticket."

Yan Jiecheng smiled and said, "Just treat it as me inviting you to a meal."

After hearing this, several people were all senior technicians, and everyone didn't care about the money, so they didn't object any more, and thanked Yan Xiecheng.
