Not only Zhao Zongrong, but even Liu Feng also looked at Chu Jianghe, and was somewhat surprised that Chu Jianghe quoted the price.

Before coming, Chu Jianghe didn't even communicate with Zhao Zongrong and Liu Feng, although Chu Jianghe represented the Design Branch of Chutan Railway Bureau, and belonged to the same front as Chutan Railway Bureau, but bidding is such a thing, it is better to avoid suspicion, which is good for anyone.

What's more, in Chu Jianghe's opinion, his own price is definitely the lowest price.

As for the other five major design institutes, they were all dumbfounded when they heard Li Tao's quotation from Chu Jianghe.

After a short period of silence, there was a lot of discussion in the conference room again, and many people looked at Chu Jianghe with unkindness, and many of them were sarcastic and disdainful.

"The following major design institutes, according to the quotation of each institute, explain the general idea of the design, first of all, please ask the person in charge of the first survey and design institute to come to the stage. Li Tao paused for a while and then spoke.

The person in charge of the First Survey and Design Institute was an old man, with gray hair, not tall, and very simple dress.

Chu Jianghe was not familiar with the other party, but he only knew that this person's surname was Fan, and he was a vice president of the First Survey and Design Institute.

When Li Tao finished speaking, the two young people who followed before brought a blackboard and placed it on the stand in the middle of the podium.

Dean Fan came to the stage, looked at everyone, and said slowly: "Good morning, all the leaders and colleagues who sit down, about the railway with an average speed of 160km/h from Shenzhen to Chutan City, I will give a brief explanation here on the ideas of our First Survey and Design Institute. ”

In the audience, everyone listened attentively, although the first survey and design institute has the highest quotation, but every design and budget, has its rationality, as the five major railway design institutes in China, there are a large number of experts, they can not design a railway casually.

Each designed railway must be reviewed by the Ministry of Railways to see whether the design is reasonable.

Therefore, the budget given by the First Survey and Design Institute must have his reasons.

"From the existing railway geology from Shenshi to Chutan City, we know that most of the geology in this section is yellow map, clay and gravel, and there are weak foundations, and the foundations are not stable. The construction of railways on this kind of geology requires relatively high bearing capacity of the foundation. Dean Fan explained slowly.

Everyone in the audience agreed with what Dean Fan said, because the existing geological conditions are like this.

To build a railway with an average speed of 100km/h, the geological requirements may not be high, and the settlement of the roadbed is not so strict, but the average speed is 160km/h, but it is completely different.

"The design idea of our first hospital is very simple, that is, the method of replacing the road with bridges, and most of the whole process is in the form of viaducts, and some places with good geology are in the form of roadbeds. For the bridge section, bored piles are used for construction. Dean Fan said.

Replacing roads with bridges is the most common in the era of high-speed rail, and even the world's most famous Qinghai-Tibet Railway, in the face of permafrost, also adopts the method of building bridges.

The design of the First Survey and Design Institute was basically within Chu Jianghe's expectations.

The bridge instead of the road does solve the problem of foundation bearing capacity, but there is a major problem, that is, the cost of the railway, which will increase greatly.

Jinqiao Silver Cave, this is not as simple as saying.

It is normal to double the cost of replacing the road with bridges!

Almost as soon as Dean Fan finished speaking, everyone knew why his budget was so large!

However, in Chu Jianghe's view, even if this railway is used as a bridge instead of a road, it does not need to spend a budget of 5 billion!

Dean Fan stepped down in less than 15 minutes after explaining, except for the bridge instead of the road, the design of the First Survey and Design Institute has no bright spots.

Then it was the turn of the Second Survey and Design Institute to come to power, and compared with the First Survey and Design Institute, the Second Survey and Design Institute also adopted the method of replacing the road with bridges, but the cost was less than that of the First Institute.

After the second institute finished explaining, it was the turn of the third survey and design institute.

In addition to the design branch of the Chutan Railway Bureau, which has an outrageous quotation, it seems to everyone that the Third Survey and Design Institute and the Railway Corps Science and Technology Research Institute are qualified to compete for the design qualification of this railway.

After all, the quotations of the two are similar, and as for Chu Jianghe's offer, there is not enough reason to do so, and it will generally not be adopted.

Therefore, until now, the five major design institutes still haven't taken Chu Jianghe into account.

The person in charge of the Third Courtyard was Shen Hui, who came to the stage with a smile, looked around, and paused for a while at Chu Jianghe before speaking.

"Comrades, let me explain some of the designs of the three academies for this railway, for this railway, our method is to use a combination of bridges and roadbeds to build it. Shen Hui said.

In fact, all of you are experts, and according to the quotations of each hospital, you can basically guess the design method of each hospital.

"For places with good geology, directly use the roadbed, for places where the geology is okay, our institute adopts the method of replacing two meters to three meters to design, and for places where the geological conditions are too poor, the method of replacing the road with bridges is adopted. Shen Hui said.

This method is also the most reasonable way, reasonable at the same time, but also save money, after all, relatively speaking, the roadbed saves a lot of money than the bridge.

Relatively speaking, replacing the original foundation also saves a lot of investment than building bridges.

"The reason why the railways designed by our institute are longer than the ones that have been built are mainly because of the increased speed and the fact that we have adopted a larger radius of curves. According to the discussion participated by each institute in 84, if the average speed of the train reaches 160km/h, then the minimum curve radius must be more than 1200m, therefore, in this design, the curve radius we designed is a minimum of 1200m and a maximum of 3000m......" Shen Hui stood on the podium and said the design of the three institutes.

For the 84-year seminar, Chu Jianghe also knew that at that time, under the leadership of the Ministry of Railways, many old experts in railway design from the five major design institutes, and professors from a series of universities such as Tsinghua University, Lanzhou Jiaotong University, Shanghai Jiaotong University, and Southwest Jiaotong University all participated in the seminar.

The content of the discussion is that the speed of 160km/h, what kind of curve radius is suitable, and how high the outer rail is, so that passengers will not feel uncomfortable when sitting in the car.

After a series of calculations, everyone has always believed that the radius of the curve is more than 1200m, and the train will not feel uncomfortable when passing through the curve.

Like the last time he ran 160km/h for the sake of the trial operation of the Shentan Railway, Chu Jianghe sat on the car, obviously feeling uncomfortable, and some people even wanted to vomit.

At the same time, the vibrations of the train are also very frequent, and the danger is very high.

The Third Iron Institute took this into account, obviously the other party really put his heart into account, relatively speaking, the first and second survey and design institutes did not take into account such meticulousness.

Shen Hui spoke for a full twenty minutes, and finally walked off the stage with a red face, in Shen Hui's opinion, his explanation was already very good.

Then came to power the Fourth Survey and Design Institute, and the method of the Fourth Survey and Design Institute was half roadbed and half bridge, and the cost was still high.

Perhaps because he felt that the probability of winning the bid was not large, the person in charge of the Fourth Survey and Design Institute stepped down after explaining for less than ten minutes.

When it was the turn of the Academy of Science and Technology of the Railway Corps to come to power, it was a middle-aged man in his thirties.

Chu Jianghe didn't know the other party's specific position, he only knew that the other party's name was Ma Xiao.

For the design of the Institute of Science and Technology of the Railway Army, it is similar to that of the Chujiang River, where the geology is particularly bad, bridges are used, and in other places, all the roadbeds and culverts are designed.

"In the face of the fact that ninety percent of the lines are roadbeds, our design institute is ready to design other foundation treatment methods in addition to foundation replacement at this stage to strengthen the foundation. Ma Xiao continued.

"Mr. Ma, do you mean that your design and railway budget are just an estimate of yours?" When everyone heard this, Shen Hui of the Third Academy couldn't hold back.

Now in Shen Hui's view, that is, the Railway Soldier Science and Technology Research Institute, there is a threat to them, and now it seems that there are still loopholes in the design of Ma Xiao and others.

"Yes, but we've found a way to strengthen the foundation, and the budget should not be too different. Ma Xiao said as usual.

In such a short period of time, it is indeed not easy for them to study a new set of foundation reinforcement measures, not to mention the release of this set of design, followed by the corresponding equipment manufacturing, which cannot be completed in a short time.

"What Mr. Ma said is, but I personally think that design and construction are the same as rigorous things, and besides, the design period of this line is tight, I don't think the Chutan Bureau should give so much time. Shen Hui said in a tone of self-talk.

Hearing Shen Hui say this, many people who sat down again nodded, indeed, as he said, the Chutan Railway Bureau was in such a hurry to let everyone come up with a design plan, didn't it just want to build it earlier?

Obviously, there is great uncertainty in the plan of the Railway Military Scientific Design and Research Institute, and even if the asking price is lower than that of the Third Survey and Design Institute, it may not be adopted by the Chutan Railway Bureau.

"Indeed, once the bid is won, the next step is on-site geological exploration, and the construction drawings must be issued within nine months. Li Tao added at this time.

As soon as Li Tao said this, the probability of winning the bid on Ma Xiao's side was even smaller.

In the end, Ma Xiao explained again, and then stepped down, his face was a little gloomy, it was obvious that Shen Hui and Li Tao's words were very unfavorable to their design institute.

"Please the person in charge of the Design Branch of the Chutan Railway Bureau to come to the stage to explain your design. At this time, Li Tao looked at Chu Jianghe and spoke.

At this moment, not only Li Tao looked at Chu Jianghe, everyone present looked at Chu Jianghe, the only representative of the Design Branch of Chutan Railway Bureau!

In everyone's eyes, there were curiosity, surprise, expectation, disdain, and sneer, everyone's expressions were different, but in Chu Jianghe's opinion, the vast majority of people wanted to see their own jokes.

Chu Jianghe touched his nose, slowly stood up, and walked towards the stage.

Chu Jianghe knows that next, it is time to play by himself, how to convince everyone sitting is directly related to this line, whether he can win the bid!
