In the early days of liberation, the sleepers used in domestic railways were all wooden sleepers soaked with asphalt, and the wooden sleepers could be insect and corrosion-proof after being soaked in asphalt. Pen, fun, pavilion www. biquge。 info

However, there are many disadvantages of wooden sleepers, first of all, the weight is relatively light, for low-speed trains, there is not much problem, once the train speed is increased to more than 80Km/h, there are great safety hazards.

In addition, the widespread use of wooden sleepers, the consumption of wood is too large, the maintenance cycle is shorter, in order to reduce the felling of trees and reduce the replacement of railway sleepers, in 195 years, a large number of concrete sleepers were used in China to replace wooden sleepers.

The advantages of concrete sleepers are that the felling of trees is greatly reduced, the service life is long, the track stability is good, and it can meet the requirements of high speed and large volume.

For concrete sleepers, in the past nine years, Chu Jianghe has participated in the optimization of type II concrete sleepers, and developed a new type II concrete sleeper, which meets the basic requirements of high-speed railways.

However, for the early development of type I sleepers, Chu Jianghe does not know much about it.

"What a connoisseur, when I was in town, I happened to meet an old intellectual, who was an expert in railways, and I learned a lot of knowledge from him. Chu Jianghe found a reason to fool around.

"Brother Chu, now there are Ia sleepers, and I sleepers have begun to be eliminated two years ago. Li Xiandeng didn't care and explained.

Hearing Li Modern's words, Chu Jianghe's heart couldn't help but move, according to Li Modern's words, that is to say, domestic concrete sleepers have not really developed.

Whether it is a type I sleeper or an Ia type sleeper, the fasteners used are not spring fasteners, that is, spring fasteners may not have been invented in this era?

For the shape and design of the spring fastener, Chu Jianghe has long been familiar with it, because when the new type II sleeper was studied, it was fine-tuned after an in-depth understanding of the existing spring fasteners, so that the mechanical curve that plays a cushioning role can reach the most perfect.

"Can a new Ia sleeper be sold for 30 yuan now?" Chu Jianghe thought for a while and asked.

Thirty years later, the price of a new Ia sleeper is about 130 yuan, because the railway is a closed industry, a newly developed Ia sleeper in eight years is likely to sell for 30 yuan a piece.

"How can there be, it's only 24 yuan a piece, and now there are several manufacturers of this kind of sleeper in Chutan City, and the competition is too fierce. Li Modeng said.

For manufacturers who can produce sleepers, it is absolutely 100% related, the same thing, as for who can sell more, it depends on their respective means.

"They all sell the same sleepers, and the competition must be fierce, but you haven't thought about developing a new concrete sleeper?" Chu Jianghe said jokingly: "In this way, you can apply for a patent, and then the world can only produce it, and if others want to produce, you have to give patent money." ”

"Patent, Brother Chu, your idea is too advanced, how can we develop this thing, it was developed by a group of old experts in the design institute, we don't understand this aspect, besides, even if you develop it, will the state allow you to use it? This is something used in the railway industry, without the consent of the state, no one dares to start this." Li Modeng said.

Chu Jianghe still agrees with Li Modern's words, especially in the railway industry, which requires the approval of relevant documents, and it is completely impossible to supply materials to the railway without certificates, or to use a new type of material equipment.

Chu Jianghe pondered for a moment and said, "Modern, do you have any pictures of the appearance of sleepers?"

"Yes, yes, but in the company, I didn't bring it, Brother Chu, why do you want this?" Li Xianden wondered.

Even Wang Guangyuan looked at Chu Jianghe curiously, not knowing what kind of medicine this guy was selling.

"Five years ago, before the old intellectuals in my town left, he gave me a copy of the drawings he made, and I asked him what this drawing was, and he told me that it was a new sleeper designed by him, and I wanted to see if the sleeper he designed was the same type as the one you are using now, because he heard from his family that he was an expert in a design institute in China, and he didn't know whether it was true or false. Chu Jianghe found a reason and said.

As soon as Chu Jianghe opened his mouth like this, Wang Guangyuan and Li Xianden both showed surprise, they did not doubt Chu Jianghe's words, because in their opinion, the reason why Chu Jianghe knew about sleepers must have involved this knowledge.

But it was surprising to hear that an old intellectual, who actually designed a new sleeper five years ago, and why did the other party give this drawing to Chu Jianghe?

"Why don't you go to the company first, I'll show you the photos. Li Modern has a keen sense that Chu Jianghe's words are very important.

Li Modern's company was nearby, Wang Guangyuan turned around and arrived, and in less than five minutes, Li Modern took the company's publicity photo and handed it to Chu Jianghe.

After taking a look, Chu Jianghe could see at a glance that this kind of sleeper was an Ia-type sleeper, and the fasteners used on the sleepers were indeed not spring fasteners, or buckle fasteners, Chu Jianghe's heart couldn't help but get excited, and he felt that this was a good opportunity.

Once you design a type II sleeper and apply for a patent, it will be a matter of promotion and application, once it is promoted, even if Chu Jianghe does not produce it, others use their own patents, you can also charge patent fees, and a sleeper will draw a dime, which will also be a huge amount of money.

You must know that all over the country, how many railways will be built in the future, and the number of sleepers needed, is definitely a terrifying number.

In addition, Chu Jianghe plans to open a research institute, and in two years, the new Type II sleepers will also be designed, and he has been walking in front of the old guys in the design institute, which can be regarded as making some contributions to the domestic railway industry!

The key is how to promote, and it is very important to get the consent of the relevant leaders of the Ministry of Railways.

"Brother Chu, how is it, is it the same as yours?" asked Li Xianden.

"It's different, I remember the drawings given to me by the old intellectuals, fasteners with springs, which are completely different from yours. Chu Jianghe shook his head and said.

"Spring fasteners, what is this?" Li Modern was stunned for a moment, his face showed curiosity, and said, "Brother Chu, if you don't mind, can you bring it to me?"

"Modern, I would like to ask, do you have any experts in railway design here, that is, experts who are more proficient in this area. Chu Jianghe didn't answer Li Modern's words and asked.

"I don't have one, but if you want to find it, I can help you get in touch. Li Xianden said very clearly.

"Okay, I'll go back and find out what the old intellectuals gave me again, study it carefully, and the next time I come to Shenzhen, you can find me a few old experts, and I'll discuss it with them." "The Chu River channel.

What Chu Jianghe has to do now is to get the approval of these old experts, and then Chu Jianghe will find another opportunity to apply for a patent, and the next thing is how to get through the Ministry of Railways.

To contact the Ministry of Railways, Li Xiandeng's level is still too far away, unless Zhao Bingyao's father goes out in person, he may still be successful.

How to get the other party to agree to go out is very important.

"Okay, that's on me. Li Modeng said.

"Brother Chu, what kind of educated youth are you, the previous one taught you German, and this one taught you railway knowledge, you are divine. Wang Guangyuan said enviously.

"It's a complete coincidence, I didn't know that these things would work for me before that. Chu Jianghe smiled awkwardly.

"Brother Chu, you can also speak German, what university did you go to?" Li Xianden said in surprise.

"Go to a fart university, Brother Chu is self-taught, and he relies on the old intellectuals. Wang Guangyuan said.

"Simple communication should be fine. Chu Jianghe coughed.

"Isn't it, that's okay?" Li Xianden embarrassed.

While chatting, the three of them drove forward, and soon came to the door of a residential building.

"Modern, you go and call Xiao Xu and say we've arrived. Wang Guangyuan said.

"Okay, you wait. With that, Li Xianden got out of the car.

Fortunately, there was a phone booth on the side of the road, and in less than five minutes, a man with a small head, middle-haired hair, and a pair of glasses came down.

"Modern, why did you all go, I was waiting for you at home for half an hour, and I called your home to say that you went out and couldn't contact you. The bespectacled young man glared.

"Okay, don't talk nonsense, I'll find you two at night, haven't you always liked Xiaoqing in the city that never sleeps? I'll give you a bag tonight." Li Xian said angrily.

"I'll go, I'm so generous today, that relationship is good, no, where is one enough, I want both!" said the man with glasses.

"Can you do that little Dingding?" said Li Xianden with disdain.

"Get out!"

"Xu Min, don't talk nonsense, don't talk nonsense, you two get in the car quickly. Wang Guangyuan said loudly in the cab.

After the two got into the car, Li Modern introduced Xu Min: "Xiao Xu, let me introduce you, Brother Chu of Chu Jianghe, the big boss from Chutan City, Brother Chu, this is Xu Min, the youngest of our three musketeers, this kid is the." ”

"Get out, the dog can't spit out good words in his mouth!" Xu Min glared, then his face changed, and he smiled at Chu Jianghe: "Brother Chu, my name is Xu Min, welcome to Shenshi." ”

"Hello, please take care of me in the future. Chu Jianghe shook hands with Xu Min.

"Don't worry, I can't help you with the rest, when you get to the deep market, if you want to find a girl, it's definitely no problem to find me." Xu Min patted his chest and reassured.

"Brother Chu, Xiao Xuzi's words are true, his industry in Shenzhen not only involves railways, but also opens two companies in entertainment. Wang Guangyuan mentioned.

Chu Jianghe was stunned, he didn't expect this Xu Min to have such a hand, seeing that he is not very old, he is so capable, but looking at his thin figure, I don't know if he has done too many bad things, and he must have harmed many women.

"It's useless, sign a few actresses, one is longer than the other, and I go to the city that never sleeps. Li Xianden said with disdain.

"Modern, if you don't speak, no one will treat you as dumb. Xu Min snorted, obviously, the two were very wrong, but Chu Jianghe didn't seem to be really angry when he saw the two, it should be a habit. (To be continued.) )
