The Boss of the Yan Family in Siheyuan

Chapter 247 Chief Designer Yan is online again
The leader came to Yan Jiecheng for no other reason than to find out about the performance of the Gaoyi locomotive.

Of course, the leader is not idle and has nothing to do to pay attention to a motorcycle.

Instead, the country is planning to build an intercity railway from Beijing to Tianjin.

This railway, in addition to undertaking rail traffic between the two cities.

The main thing is to conduct research and practice on the theory of high-speed railway proposed by Yan Jiecheng.

After all, this bastard, Yan Jiecheng, published several papers related to high-speed railways in their association's journal.

Regardless of whether it is from the development trend of railways or the impact of high-speed railways on the economy, Yan Jiecheng has always praised high-speed railways.

As a result, these articles written by Yan Jiecheng were seen by senior leaders.Through the arguments of a group of experts, I feel that what Yan Jiecheng said is reasonable.

It was then decided to build a Beijing-Tianjin passenger dedicated line and see the results first.

Since the leaders have decided, they must implement it.

But currently, the only one who can undertake the high-speed railway project nationwide is the improved locomotive integration system developed by Yan Jiecheng and his research institute.

That's why the leader called him over to learn about the system in detail.

After knowing the purpose, Yan Jiecheng naturally praised the improved locomotive integration system of their research institute as if it were a flower.

The leader saw his mother-in-law selling melons and bragging about herself.

He waved his hand and said, "You kid, don't talk nonsense to me. Let me ask you, can your integrated system guarantee a top speed of 180 kilometers per hour?"

Yan Jiecheng said with a smile: "Boss, don't trust me because I have never made mistakes in my work.

I can't guarantee it elsewhere, but if our integrated system is placed on the Beijing-Tianjin line and used exclusively as a passenger train, it can completely guarantee a speed of 180 kilometers per hour. "

The leader thought for a moment and said: "Okay, in that case. Your office will be responsible for the overall design of the Beijing-Tianjin intercity passenger line."

Yan Jiecheng smiled and said: "Don't worry, leader, I'm familiar with this job. I promise to complete the task."

The leader smiled and nodded and said, "If I hadn't known that you were responsible for the overall design of the Beijing subway back then. With your careless attitude, I still wouldn't trust you to hand it over to you."

Yan Jiecheng looked at the other party with resentment and said: "Boss, we are not close to you, but when you come here, you say that we are just doing nothing."

To be honest, Yan Jiecheng was not very familiar with this leader before, and everyone only knew that there was such a person.

In the past few years, the situation in the ministry has changed, and many new leaders Yan Jiecheng are not very familiar with it.

But even if everyone is not familiar with him, they have learned a lot about Yan Jiecheng, and they know that Yan Jiecheng is now a big tree with deep roots.

Therefore, I usually don’t dare to look down upon it.

Yan Jiecheng naturally wants benefits from the work assigned by the leader.

So he said: "Leader, you know our situation. The stalls are relatively large and there are many research projects.

So, everyone's life is not easy now.

This is responsible for the overall design of this new line.

Everyone in this wilderness has to climb mountains and wade through rivers, so we must provide benefits to everyone.

See if you can provide support here. "

In Yan Jiecheng's opinion, this is normal.

Even if you are a superior unit, you cannot ask us to work in vain.

Besides, for such a large project, no matter what the design cost, it will be calculated.

You can't go whoring in vain!

Yan Jiecheng felt a little embarrassed when the other party looked at him, but he still insisted: "Boss, our clever wife can't do this without rice.

Anyway, you mean it and I support it.

Give me a funding of 80 million. "

“I’ve always said that we need to look at the overall situation and look beyond the horizon.

Don't keep staring at your own one-acre three-point land.

Besides, isn't your research institute also owned by the state and our ministry? Why are you so divided?
You still have a mouthful of 80 yuan.

Look how much I'm worth, you take it and sell it.

I can only grant you 30 yuan here. Do you want it? "

Yan Jiecheng said with a wry smile: "Leader, it's not enough.

You know, our experts are engaged in technology research and development.

Designing this route requires a lot of work.

Just take pity on me, and it can't be less than 60. "

Yan Jiecheng thought to himself, Boss, if you design a railway with 60 yuan, you will make a lot of money anyway.

Although Yan Jiecheng also knows that currently, research institutes like theirs are responsible for designing railways, but they don't have a penny of funding.

But Yan Jiecheng really dared to ask for it, because the government could only provide part of their research funding, and they had to raise the rest themselves.

Over the years, if it were not for the support of Hongxing Home Appliances Factory, how would the institute have achieved what it has today?
So he took every opportunity to ask for money.

The leader may be thinking that research institute is indeed not easy.He nodded and said helplessly: "Okay, I will grant you up to 50 yuan here. Just think of it as giving it to your research institute and increase the research funding this year."

Yan Jiecheng quickly shouted that the leader was wise.

Yan Jiecheng received the task and hurried back to the office.

We organized an internal meeting to determine the design team for this Beijing-Tianjin intercity express line.

Of course, he is the chief designer.

It’s not that no one in their institute is capable of taking on this matter.

But this route is different from the past after all.

All the equipment is brand new, the design standards and concepts are different from the past, and the design specifications are of no use.

Everyone has no experience and no basis for reference.

Therefore, Yan Jiecheng became the chief designer of this project without hesitation.

In the final analysis, this dedicated line is an acceptance and test of the results of the technology accumulated over the years.

Not only high-speed rolling stock, but also other technologies will be used.

Seamless lines must also be installed.

In the past few years, Yan Jie became a seamless line of their argument, although they achieved a theoretical breakthrough.

But the 200-meter-long steel rails are still used on the line.There is no truly seamless line.

Yan Jiecheng thought that this time he must lay a ballasted and seamless line.

According to his idea, 100 meters of rails were first prefabricated in the factory.

Then it is transported to the rail welding base, where it is welded into a 500-meter long rail.

After welding, grinding, and inspection, the rails are transported to the laying site, and then welded to other rails again, eventually becoming a seamless line dozens of kilometers long.

Then we mobilized relevant experts from the institute to form a large design team.

For the route this time, follow Yan Xiecheng's intention.

First of all, it is a fully enclosed road.

Both sides of the line must be fenced with iron mesh.

Passers-by, employees, and children cannot come in and out at will, stay and play on the line like in the past.

You must know that the speed of the line currently being designed has reached 180 kilometers per hour.

If there is any unexpected situation ahead, it is impossible to brake.

Therefore, this requires an absolutely safe driving space.

Besides, theft often occurs on lines as in the past.

Things like fasteners and road spikes have become stolen items.

But this high-speed railway has extremely high line requirements due to its high speed.

If fasteners etc. are disassembled, serious accidents may result.

Therefore, closed lines are an inevitable result.

At the meeting, Yan Jiecheng confirmed the equipment upgrade status of each system.

You know, high-speed railways don't just require a fast car.It also requires that various systems cooperate with each other and coordinate with each other.Only in this way can a complete and organic whole be formed.

Take the line for example.

In the past, ordinary lines used spikes to nail the rails to wooden sleepers.For this type of line, the buckling pressure of the road spikes is low.

Rails have extremely poor resistance to longitudinal and transverse resistance. During high-speed train operation, rail deformation and rail displacement are very easy to occur.

Therefore, in order to cooperate with the operation of the improved integrated system in the first grade of high school.A specially developed new type of fastener and concrete prestressed sleeper.

For this kind of fastener, the road spikes are first embedded in the concrete prestressed sleepers.

The upper part is a buckle plate that can adjust the gauge.It is composed of a W-shaped high-strength elastic steel elastic strip that increases elasticity, as well as a washer and a nut.

The entire buckling pressure can reach 150 Nm.

Through this kind of fasteners and sleepers, the frame rigidity of the line track can be greatly improved.

Without such fasteners, Yan Jiecheng would not dare to design seamless circuits.

After all, the long rails of the seamless line expand with heat and contract with cold when the seasons change.Strong stresses are generated inside which displace the rail longitudinally.

This longitudinal force is extremely large if the fastener cannot provide sufficient buckling force.

The fastener loses its restraint on the rail.The frame size of the track is compromised as well as the frame strength.It will pose a serious threat to driving.

After the meeting, Yan Jiecheng thought about this design and the construction of the subsequent lines.

So, do the school textbooks need to be revised again next year?

Students' lives can be enriched.

I don't know, they know this.Would you like to thank him for being such a dedicated teacher?

the next day.

Yan Jiecheng saw off the staff who went to the Beijing-Tianjin line for on-site inspection.

This kind of work certainly does not need to be done by him personally.He just needs to inspect those special places for himself.

Yan Jiecheng has been a little excited these past two days, as if a stone that had been accumulated in his heart has been lifted.

He couldn't help but get excited when he thought that he would be in charge of designing the first high-speed passenger line in his country.

For this reason, Yan Jiecheng defined this project as a take-off project within their research institute.

The entire design team can be described as luxurious.Not to mention Yan Jiecheng, other designers are also industry giants.

Yan Jiecheng couldn't help but think of the time when he and Lao Xie went to the northwest.

At that time, there was no one available in the ministry, so everyone wanted to give him a try and asked him to take charge of the design of the industrial line.

Time passed by more than ten years.

Now, he finally has the opportunity to design a real railway in his mind.

Time is fast.

A week later, their design team came up with an overall design plan.

This design plan involves the overall goal of the overall design of the line.

According to their plan, the line track adopts the design of closed ballasted seamless line.

The locomotive signal, of course, uses their improved integrated system.

Regarding the power supply method of the locomotive, Yan Jiecheng and others decided after discussion to adopt a 25 kV flexible catenary system.

To be honest, the overall work of designing this kind of line is much more than that of traditional lines.

In the design of traditional lines, there are only two rails and stations, and some communication signals.

Then add the rolling stock and you can run away.

This new line needs to consider issues such as interval blockage and locomotive power supply.

Therefore, the power supply major plays a large role in their design work.

Not only the design of the contact network must be taken into consideration, but also the specialized facilities and equipment on the electrified railway, such as substations and traction stations in the power supply zones.

Yan Jiecheng took the overall plan blueprint and reported to the leadership.

The leader looked at the plan Yan Jiecheng gave him.

After Yan Jiecheng drank three cups of tea, he raised his head.Looking at Yan Jiecheng, he said, "You are planning to kill me.

You can see that you not only need to use double lines or seamless lines, but also close the lines.You are not building a railway, you are building a mountain of gold.

There are also these 13 substations..."

Yan Jiecheng was there silently listening to the leader's chatter.As a leader, it's the same.It makes you feel bad when you spend too much money.

After the leader finished speaking, Yan Jiecheng hurriedly said: "Leader, you must not be stingy.

Take a look and follow our design blueprint.Think about it, what will happen after this dedicated passenger line is completed?
That is the first one. Not only domestically, but also globally, he is not lagging behind.

This is not just a railway.

This is a shining golden achievement.

Let's also let others take a look. After so many years of development, our country's railway industry has achieved good results, isn't it?

Compared to these, what is money? "

The leader listened to what Yan Jiecheng said.There was some agreement in my heart, yes, this is simply putting the results out there for everyone to see.

But thinking about the approximate budget given by Yan Xiecheng and the others, it was [-] billion.

Yan Jiecheng looked at the pained expression on the leader's face, and knew that he had ideas about the budget.

Yan Jiecheng also knew that the budget for his railway was three times higher than that of other lines.

But this is already the result of Yan Xiecheng and the others trying their best to save costs.

After all, this is also a high-speed railway.

It was also in this era, if the railways of more than one hundred kilometers in later generations would cost tens of billions.

To be honest, I looked at the pained expression on the leader's face.Yan Jiecheng's own heart was bleeding.

For this billion-dollar project, their design team only took 50 yuan. Who would believe it?

Who knows, these days, no one can operate independently, so they can only work in vain.

This 50 yuan is not just the design fee.Instead, the ministry gave them additional R&D funding.

Yan Jiecheng can also imagine that after the construction of this railway is successful.It would be good if each of these related designers could be rewarded dozens of dollars.

No wonder everyone will go to sea in a few years.

Although the leaders felt sad, they knew that this railway must be built.They agreed to study it into their overall design plan.

After the overall design plan is approved.

Yan Jiecheng and the others need to wait for the on-site survey personnel to get back the specific data, and then give a specific line selection plan.

Let leaders choose slowly.

Of course, maybe their line selection plan will be completely overturned.

After all, line selection involves the interests of all parties, and it is inevitable that everyone will have disputes.

Who wouldn’t want a train station at their doorstep?For these reasons, all localities will definitely show off their talents, building relationships and running departments everywhere.

Of course, what does this have to do with Yan Jiecheng?When the time comes, the most important thing is to say nothing and refuse.

It is better to leave this issue to the leadership.

After all, he is strong and tall.

I am just a little designer.

Yan Xiecheng knew that the opening of this line would not be soon.

After all, it is the first time from design, construction to operation, and everyone needs to get used to it and learn.

Especially in operations, a large number of employees need to be retrained.

Of course, this professor is a professional.He has specialized in the organization and operation of high-speed railways in recent years.

A set of regulations was also specially compiled for the integrated system of improved locomotives for the first year of high school students.
