As early as 84 years, the 'market for technology', in the domestic coastal cities, gradually opened up and implemented, such as some automobiles, machinery manufacturing, molds and other aspects of technology, with the existing domestic technical level, there is no way to produce. Pen & Fun & Pavilion www.biquge.info

At this time, it is particularly important to absorb foreign advanced technology, and through digestion and absorption, finally form China's independent research and development capabilities, and provide China's technological innovation level.

Relatively speaking, the introduction of ordinary manufacturing technologies such as excavators and forklifts should not be a problem, mainly in the technology of key parts, whether foreign countries are willing to sell. For the cooperation between Chinese and foreign enterprises, the vast majority of foreign capital sells some technologies and key technologies that are not highly researchable, and even the production line will not be sold, so they can only pay an expensive set from foreign capital to buy a complete set and assemble it after being shipped back to China.

The technology mentioned in the mouth of the Chujiang River actually refers to some key technologies, ordinary technologies, which have been carried in the process of purchasing assembly lines.

"It's better to bring in some key technologies so that it really helps us. "The Chu River channel.

Of course, the reason why the head office has not made a decision is because some people internally believe that important and core technologies cannot be sold abroad, and even if they are exchanged for the market, they may not be successful. Zhao Guodong said.

"If we don't do it, we will continue to change, presumably in terms of construction machinery manufacturing, there are no other companies to choose a cooperative company in Germany. "Chu Jianghe, in fact, Chu Jianghe did not refute the other party, even some ordinary technologies in China are far less good than those abroad.

Nowadays, most of the state-owned enterprises choose to cooperate with Japan and the United States, and for Germany, there are quite few enterprises that really cooperate.

"Jiang He, among the members who went to Germany this time, I also reported your name, in addition to you, there is another translator from the head office, the reason why I have been proposing to let you participate is mainly because you know more about construction machinery than that translator, of course, before going to Germany again, the head office may have to conduct an assessment of your German, no opinion, right?" Zhao Guodong said.

For the assessment, Chu Jianghe didn't feel anything, even if Zhao Guodong fully believed in himself, but he was not the leader of the head office after all, and he couldn't make a final decision.

"No problem, I'm going to go to Shenzhen in the next two days, I don't think I'll be able to do it next week. Chu Jianghe thought for a while.

Qiao Tianhong will come to Shenzhen in the past two days, Chu Jianghe is ready to discuss with the other party about joining the design company, once Dean Qiao Tianhong joins the design company, Chu Jianghe's hanging heart can be put down.

Because in Chu Jianghe's next move, Dean Qiao Tianhong is a very key figure.

"Go to Shenzhen, our head office is in Shenzhen, no, I'll accompany you to go there in the next two days, and then discuss a time, what do you think?" Zhao Guodong said.

"That's fine. Chu Jianghe nodded, it would be better this way.

Two days later, the Shenzhen market.

In order to promote the new concrete sleepers and elastic fasteners used by the Shentan Railway, Zhao Zongrong convened Qiao Tianhong and other experts in the railway industry to hold a two-and-a-half-hour meeting with Chu Jianghe, and the content of the meeting focused on how to write this article and how to make it easier to refer to it.

These experts in the railway industry are inextricably linked with the Chutan Railway Bureau, so in the face of Zhao Zongrong's invitation, they all tried their best to find a way.

After the meeting, Chu Jianghe specially found Dean Qiao Tianhong and prepared to talk to him alone.

"Dean Qiao, presumably Ju Zhao has already told you, about the matter that I want to invite you to join my survey and design company, I don't know what your opinion is Dean Qiao?" Chu Jianghe got straight to the point.

Qiao Tianhong took the cigarette handed over by Chu Jianghe, and Chu Jianghe lit it for him, don't look at Qiao Tianhong has retired, as a person of their generation, they are all old smokers.

In their opinion, smoking is a fashion, because when Mao Chairman, when receiving foreign guests, he likes to smoke, which eventually influenced a generation.

Qiao Tianhong took a deep breath, and after spitting it out, he sighed: "Xiao Chu, Zhao Ju did tell me about this, Zhao Ju also meant to let me join, and I myself am also very willing to join, but in the past two years, my body has become more and more bad, although you have no restrictions on us old bones to join, and the requirements are very low, but I am really a little powerless." ”

For Qiao Tianhong's refusal, basically in Chu Jianghe's expectations, Zhao Zongrong and Qiao Tianhong when he told Qiao Tianhong about the matter, must have mentioned the nature of Chu Jianghe Company, although this company Chutan Railway Bureau may also occupy shares, stained with the nature of state-owned enterprises, but Chutan Railway Bureau is a small number of shares after all, relatively speaking, whether it is a survey or design company, it is Chu Jianghe's shares occupy a leading role.

Qiao Tianhong, as a retired expert of the Royal Design Institute in China, asked him to join a privatized company after retirement, and serve this company, not to mention anything else, from the face point of view.

"Dean Qiao, don't be in a hurry to refuse, after I finish speaking, if you still don't agree, just don't I say it, do you think this is okay?" Chu Jianghe said unhurriedly.

Like this kind of old expert, after retirement, the state has done a very good job in all aspects of their protection, they have no worries about food, housing and transportation, and their children's work has also been arranged, plus their ideological consciousness is quite high, and if they want to use money to put an expert like Qiao Tianhong, I am afraid it will be difficult to succeed.

To convince an old expert like Qiao Tianhong, it is necessary to find his shortcomings, or shortcomings.

Before coming, Chu Jianghe seriously thought about what the shortcomings of an expert like Qiao Tianhong were.

Money, not much attraction, power and profit, now Qiao Tianhong is in his sixties, and there is no temptation, not to mention that Chu Jianghe's company is still a relatively privatized company, this kind of power and interest for Qiao Tianhong cannot be compared with the rights given by the state.

Coupled with the high consciousness, Qiao Tianhong seems to be impeccable, unless the other party personally agrees, it is difficult to convince.

In the eyes of others, high consciousness is an advantage, but in Chu Jianghe's view, advantages may also be disadvantages, since Qiao Tianhong's shortcomings cannot be found, then it will become the other party's advantages.

For an old expert like Qiao Tianhong, he has been struggling in the railway industry all his life and dedicating his life to the country's railway cause!

Relatively speaking, this is where his shortcomings lie!

Even if he retires, Qiao Tianhong also thinks about whether he can make his own contribution to the railway industry, which Chu Jianghe can affirm.

Without waiting for Qiao Tianhong to reply, Chu Jianghe changed the topic and said: "Dean Qiao, you are an old expert in the railway industry, and you are familiar with the development of domestic railways.

Seeing Chu Jianghe suddenly change the topic, Qiao Tianhong didn't care, for the factors that affect the speed of the train, of course Qiao Tianhong is clear, he said casually: "There are many factors that affect the speed of the train, such as the stability of the bridge, the treatment of the roadbed, the quality of filling and rolling, and the design of the line, such as the restriction of the curve element on the train is great, the smaller the radius of the curve, the more limited the driving speed." In addition, there is also the stability of the line and the traction system of the locomotive, which are also the top priorities, in addition to the geographical location, construction technical conditions, etc., which limit the speed of the train. ”

Qiao Tianhong obviously did not finish the example, these matters are only part of the factors that affect the speed, for example, in Chu Jianghe's view, the communication signal is one of the key factors, this difficulty, even if the Beijing-Shanghai high-speed railway is opened thirty years later, it has not been perfectly solved.

"Yes, these are the reasons that limit the speed of the train. But Dean Qiao, if I say that the purpose of my establishment of the survey and design company is to solve these difficulties and promote the development of the railway industry, do you believe it?" Chu Jianghe said seriously.

"Don't believe it!" Qiao Tianhong said decisively.

"Why?" Chu Jianghe frowned.

"The reason is very simple, the Ministry of Railways has organized a large number of scientific researchers to focus on tackling these problems, at least from the current research effect, it is not ideal, you are a private enterprise, can you be stronger than the country?" Qiao Tianhong said directly.

This is not that Qiao Tianhong looks down on Chu Jianghe's survey and design company, but a fact, in Qiao Tianhong's view, the Ministry of Railways on behalf of the state to fund these problems, so far has not been solved, Chu Jianghe is a private company, why is he so determined, he has the ability to solve these problems for the country?

What's more, Chu Jianghe's company has just been established, and he may not be familiar with the railway industry, Qiao Tianhong doesn't know where Chu Jianghe has the confidence to solve these problems for the country.

Therefore, after Chu Jianghe finished speaking, Qiao Tianhong denied it very decisively.

"Dean Qiao, there is a saying that things are man-made, for the railway industry, I can't overcome all the difficulties, but I can choose one aspect to study, I have an idea recently, I think Dean Qiao will also be interested. Chu Jianghe said with a smile.

What Qiao Tianhong said just now, Chu Jianghe admitted that what the other party said was reasonable, a private design company can never be compared with large state-owned enterprises, and the research of large state-owned enterprises has the support of the state behind them, at least there is no need to worry about funding.

And private design companies, no matter what, are for the purpose of profit, for a research, the state spent a lot of manpower and material resources can not solve the problem, who would believe that a private enterprise can help solve the problem?

But this is only limited to companies formed with ordinary people, Chu Jianghe is obviously no longer in this list, with Chu Jianghe's understanding of the railway before his rebirth, Qiao Tianhong said that all the problems, Chu Jianghe has a way to solve, now Chu Jianghe is looking for an opportunity, an excuse, relying on survey, design and design companies, will be 20 or even 30 years later, the method will be designed and practiced in advance, so that the domestic railway industry, less detours, as soon as possible to stimulate domestic demand, so that China's railways, into the high-speed railway generation!

"Tell me about it. Seeing Chu Jianghe open his mouth like this, Qiao Tianhong looked at it and said with interest.

"During this time, I did a few kilometers of subgrade engineering on the Jingtan Railway, and in my opinion, for the weak soil layer, the solution to the stability of the foundation is to replace the foundation."

"Yes, now the design institute for the design of the subgrade part of the subgrade, it can be said that it is all refilled, the geological situation is really not good, so I have to build a bridge, but the cost of building a bridge is equivalent to twice the construction of the subgrade!" Qiao Tianhong said.

The so-called Jinqiao Silver Cave, in the 80s, was based on facts, and the cost of building a railway bridge was much higher than a tunnel of the same length in the 80s.

Therefore, the railways built in the 80s were not built without bridges, and the walking routes chosen were also to avoid the unstable sections of the foundation and at the same time minimize the construction of bridges.

The less bridges are built, the more roadbeds, and the more roadbeds, because the method of foundation treatment is single, the foundation is often unstable, which ultimately affects the driving speed, which often occurs on the railway.

Therefore, in the eighties, how to solve the stability of the roadbed was directly related to the speed of the railway.

"Dean Qiao, if the problem of foundation stability is solved, will the speed of our country's train be able to reach a new level?" asked Chu Jianghe.

"It can't be said that it is 100% guaranteed, once the foundation treatment is solved, there is no problem at all for the train to maintain a speed of 120km/h, the conditions are relatively good, plus the new concrete sleepers and elastic fasteners that have just been designed, plus 60 steel rails, the average speed of 160Km/h is also possible!" Qiao Tianhong thought for a while.

"Dean Qiao, if I say that the next project that my company will study is to strengthen the stability of the roadbed, and I also have some ideas for this research, and now it is practice, I wonder if Dean Qiao is interested?"

Chu Jianghe didn't say what method he used, in order to hang Qiao Tianhong's appetite.

"What do you think?" Qiao Tianhong really became interested.

"Imitate the pile foundation of the bridge, and use the form of a group of piles to carry the load from the roadbed!" replied Chu Jianghe.

In engineering construction, there is only one pile foundation and it is called a single pile, on the contrary, there are several pile foundations at the same time to bear the load, called a group of piles.

The bridge is to adopt the pile foundation to extend into the rock formation, the load generated in the train running, through the beam body, the stepping stone, the pier body, the cushion cap, on the pile foundation below the cushion cap, because the pile foundation is not one, the load that will be passed down by the common burden train travel, and finally transmitted to the rock at the bottom of the pile foundation.

"Group piles?" Qiao Tianhong's mind kept rolling, in his mind, the first thought was the pile foundation of the bridge, but Qiao Tianhong knew that this was unlikely, and even Chu Jianghe knew that the pile foundation used by the bridge was too costly!

Obviously, the group of piles that Chu Jianghe said is different from the pile foundation construction of the bridge, if the pile foundation construction like the bridge is used, it is not as cost-effective as building a bridge, and there is no need to build a roadbed.

After all, the width of the roadbed far exceeds the width of the bridge, so the number of piles is definitely a terrifying number, and the cost will reach a terrifying level.

"Yes, it is to use a group of piles, of course, this group of piles is completely different from the piles of the bridge pile foundation, but another new type of pile!" Chu Jianghe said with a smile.

"A new type of pile!" Qiao Tianhong's eyes flickered, revealing a hint of excitement, obviously, he was tempted.
