Chu Jianghe came to the stage and looked ahead, the entire conference room, for the first time, all eyes were on the speaker, even if Shen Hui and Ma Xiao spoke just now, not so many people paid attention.

Even Zhao Zongrong and Liu Feng looked at Chu Jianghe with curiosity, wondering what amazing words he had and how to convince everyone.

"Experts, leaders, good morning, many of you here should know me, but I still want to introduce myself, my name is Chu Jianghe, is the vice president of the design branch of Chutan Railway Bureau, today our design institute bid, by me to explain. Chu Jianghe said with a smile.

"From Shenzhen to Chutan City, the existing railway is 130 kilometers, of which ninety percent of the road section is the roadbed, the rest are bridges and culverts, because the road base is not of good quality, the speed of the train, has not been able to break through 100km/h, in this geological construction of a higher speed of the railway, must be treated to the foundation. Chu Jianghe said unhurriedly.

In the audience, many people nodded, because this is the truth, but many experts showed disdain, for these materials, everyone knows, because the existing railway foundation map, can be found.

"Our design institute has basically not moved much on the new line, and still maintains about ninety percent of the roadbed, and the rest is bridges and culverts. "The Chu River channel.

For the newly built railway from Shenzhen to Chutan City, Chujianghe and Qiao Tianhong mean to keep the original state, without adding bridges, as long as it can be replaced by a roadbed, the roadbed will be used, and the purpose of this is to reduce investment.

Unless there is that kind of river, and where the road is crossed, a bridge must be built.

After Chu Jianghe finished speaking, everyone listened with interest, they were waiting, how Chu Jianghe would deal with the problem of foundation bearing capacity.

If the foundation is not treated, at a speed of 160km/h, it will definitely sink, and it will not sink a little bit, as the railway experts sitting there know it.

The design of Chu Jianghe has Qiao Tianhong involved, and he must know the factor of foundation sinking, and what everyone wants to know is how Chu Jianghe solves this problem.

"Dean Chu, you won't also use the method of replacement to deal with the foundation reinforcement. Shen Hui joked at this time, which caused many people to laugh.

Obviously, it is not feasible to use the method of replacing the foundation to reinforce, because some of the weak layers of the foundation are tens of meters deep, and this part of the soil cannot be replaced.

In addition, there are no other useful methods of foundation reinforcement for the time being.

"Dean Shen, don't worry, replacement is just one way for us to reinforce, in addition, our method is the same as Mr. Ma's idea just now, that is, to design a new type of equipment to reinforce the foundation. Chu Jianghe didn't care, and said very calmly.

"New equipment, isn't your method the same as Mr. Ma's, but now that the construction period is tight, how can you have time to study the equipment, not to mention whether you can develop it in the end is another matter, and when the time comes, who will be responsible for delaying the construction period?" Shen Hui said with a smile on the corner of his mouth.

In Shen Hui's view, Chu Jianghe is completely blind to quote, and even more unreliable than the design plan of the Academy of Science and Technology of the Ministry of Railways.

Thinking of this, Shen Hui was more confident in the design of his design institute to win this line.

Not only Shen Hui, but even the experts of other design institutes, after hearing Chu Jianghe's words, also lost interest, and some even talked in low voices.

Obviously, everyone is not very optimistic about the design plan of Chu Jianghe.

Even many people believe that the design of the Chujiang River is similar to Ma Xiao's, and the probability of being adopted by the Chutan Railway Bureau is very low.

However, Zhao Zongrong and Liu Feng were not affected in the slightest, and still listened attentively, hoping that Chu Jianghe would give a reasonable explanation.

Especially Zhao Zongrong, Chu Jianghe has brought him a lot of accidents, it can be said that if it weren't for Chu Jianghe, whether he, the director of the Chutan Railway Bureau, could sit in the position of director of the Chutan Railway Bureau is another matter.

The main reason why he participated in this bidding meeting today is that he still wants to see Chu Jianghe give himself a miracle, because Chu Jianghe once said that he is eighty percent sure of winning the design right of this railway, and Zhao Zongrong wants to see his true ability.

"Dean Shen, it seems that you are more anxious than me, are you worried that I will avoid your mark and overwhelm your three courts. Chu Jianghe asked with a smile.

"Dean Chu, it goes without saying that Lao Shen has done a lot of work for this railway, otherwise he would not have come forward in person. An old man in the first courtyard laughed and said that he didn't give Shen Hui face at all.

"Hmph, I'm worried about something, just to see what you can do. Shen Hui glared at the old man and pouted.

Shen Hui said this, but everyone sitting couldn't see his thoughts, Ma Xiao's Railway Soldier Science and Technology Research Institute was almost eliminated, and once Chu Jianghe couldn't come up with a convincing statement, the probability of elimination was also high.

In the end, the probability of the Third Survey and Design Institute winning is greater, so now it can be said that the person who cares most about what Chu Jianghe will do next is undoubtedly Shen Hui.

"My solution has already been said, which is to deal with the foundation. Chu Jianghe stated again.

"Dean Chu, can you be specific?" asked an old expert from the Second Academy curiously.

"Of course, I have two ways to reinforce, the first is called cement mixing pile reinforcement!" Chu Jianghe said lightly.

"Cement mixing pile?" When everyone heard this, they couldn't help frowning, this term was the first time they had heard of it.

Because in the previous railway design, there was no such method of reinforcing the foundation.

"What is this solution?" someone wondered.

At the same time, those old experts who didn't pay attention to it also began to concentrate and prepare to listen to Chu Jianghe's explanation.

Shen Hui's face turned white, because Chu Jianghe's method of foundation reinforcement was very specific, and he even had a name.

What's more, the other party also has two ways to strengthen the foundation, and Shen Hui has an ominous premonition in his heart.

"This kid is always at a critical moment, and he always has to come out unexpectedly. Zhao Zongrong muttered in his heart, and a smile appeared on the corner of his mouth.

Obviously, Chu Jianghe should have been prepared!

"The so-called cement mixing pile is to mix with cement slurry and soil, and form piles after solidification, but after the road foundation is driven with rows of cement mixing piles, relying on the friction and hardness of the cement mixing pile, the bearing capacity of the foundation should be increased. Chu Jianghe said simply.

"Cement slurry and soil are combined and mixed, Dean Chu, how can this be implemented?" asked the old expert of the first hospital curiously.

These old experts have worked on the railway all their lives, and many of them are very famous in the railway industry, as long as there is a new construction method, they will pay attention to it to see if this method can be promoted.

"And after the cement slurry is combined with the soil, can it really play a role in reinforcing the foundation?"

Railway design is rigorous work, and these old experts who have worked in the railway design industry for many years cannot be convinced by Chu Jianghe's words.

Just like Chu Jianghe proposed the cement mixing pile at the beginning, Qiao Tianhong and others accepted this reinforcement method after a series of calculations.

"This should not be a problem, I have some information here, experts can take a look, due to the limited number of copies, each design institute only gives one, everyone looks at each other. After Chu Jianghe finished speaking, he took out a stack of materials from the bag he brought and sent it to the experts of each hospital, as well as Zhao Zongrong and others.

"The two materials in everyone's hands, the first is the formula of Qiao Tianhong's calculation of bearing capacity and friction, which is very clear at every step, you are all old experts, you must be able to understand it. "The Chu River channel.

In order to make his statement very convincing, Chu Jianghe had to speak with data.

"The other is some experimental data obtained from field experiments, which are not accurate, but they also have a reference role. Chu Jianghe continued.

In fact, the second information is that in the last ten days of Chu Jianghe, the cement mixing pile made according to the simple machinery designed by Franz is still far from the real cement mixing pile, but it can also explain some problems.

After reading it carefully, the experts looked at each other and nodded their heads, obviously agreeing with this algorithm.

"If the results in the calculation can really be achieved, then there is basically no problem with the road-based foundation treatment, and the key is how to implement it. The experts of the Fourth Academy frowned.

"And there is still a certain gap between the experimental data and the calculated data. The experts of the three academies also spoke.

Indeed, as they said, the experimental data in the back is only a reference, and Bai does not meet the requirements of the calculation.

"I know this, the latter data is to show you that this method is indeed feasible, after all, the construction machinery has not yet been made. "The Chu River channel.

"The machinery has not been manufactured, and even if your design can strengthen the foundation, it can't be constructed, and it's not that it can't be done. Shen Hui rolled his eyes directly and said.

"Dean Chu, how long will it take for you to develop this kind of construction machinery here?" The expert of the First Academy ignored Shen Hui and asked Chu Jianghe.

Chu Jianghe also ignored Shen Hui, and said directly: "You don't have to worry about the development of construction machinery, as early as half a year ago, I negotiated cooperation with ZF company in Frankfurt, Germany, after half a year of hard work, the development of construction machinery has been basically completed, and it has been put into production in Germany, and it can be manufactured in one month at the earliest." "The Chu River channel.

"What?"

An old expert stood up with a look of surprise.

"Developed now?"

"It's still in cooperation with Germany, Germany's machinery manufacturing industry is very famous all over the world. ”

The people present were boiling, if Chu Jianghe didn't tell a lie, then once this kind of machinery is manufactured, it indicates that this method of foundation reinforcement can be completely implemented!

Some old experts are even more red-faced, excited, if it is really developed, the way to strengthen the foundation in the future, there is one more, so that the speed of the train can be increased at the same time, but also greatly reduce the construction cost.

This is undoubtedly a revolution for the railway industry!
