Chapter 126

"Then I'll just talk about it?" Gu Lu asked in a tentative tone.

Academician Guo smiled faintly, "Say it." Lao Li, you can also listen and give me some pointers. ”

Academician Li nodded lightly and looked at Gu Lu.

The rest of the dozen or so academicians also looked at Gu Lu with kindness or scrutiny.

Being stared at by more than a dozen academicians and bigwigs, Gu Lu felt a lot of pressure.

He took a deep breath, closed his eyes, and recalled in his mind the construction concept map that Academician Li presented at the morning seminar.

With Gu Lu's current memory that is far beyond that of ordinary people, he can clearly remember every detail in the construction concept drawing.

The closed eyes opened quickly, Gu Lu took a deep breath, nodded to the dozen academicians, and spoke in an unhurried tone.

"Due to its geographical location, the Bohai Strait makes all the ports and shipping routes of the Bohai Sea pass through here, and there are also 100,000-ton giant ships that often haunt it. Moreover, the Bohai Strait is also a military strategic point, and there is no possibility of building bridges. The construction of an undersea tunnel is the only option. ”

"And the technology proposed by Lin Lao, the south sinking and north shield technology is the best plan for building the Bohai Tunnel in my personal opinion. ”

In this sentence, Gu Lu did not say it for compliment, but said what he really thought in his heart.

"First of all, let's talk about the subsidence tunnel in the southern section. In the southern section of the Bohai Strait, there are many islands. From south to north, there are: Changshan Island in the south and north, Shihouji Island, Gaoshan Island, Tuoji Island, Da and Xiaoqin Island, South and North Huangcheng Island, etc., if the shield method is used for construction, it will definitely cause a large amount of silt accumulation, thereby blocking the waterway, causing alluvial plains, and affecting the lives of the people on the island. ”

"The method of subsidence is different, and only very little silt is produced. Moreover, the existence of the island does not have to worry about the transportation of prefabricated immersed tubes. ”

"We can transport the steel shell pipe sections made in the factory to the islands near the tunnels, where they can be loaded and filled with ballast concrete, reducing a lot of labor costs. ”

"In my vision, the construction process of the entire buried section of the tunnel should be like this......"

As soon as he entered the state, Gu Lu completely forgot the nervousness and oppression given to him by the previous academicians, and talked eloquently without much effort.

At the dinner table, as Gu Lu spoke, everyone's expressions gradually became surprised.

Especially Academician Li, his look of surprise was already beyond words.

People of their age have long since rarely disturbed their state of mind because of external objects.

But today's Gu Lu gave him such an experience.

What Gu Lu said was not just to express his construction concept map in his own words, but also to add some of his own unique insights.

For example, the use of the shield method will cause a large amount of silt to accumulate around the island, and the presence of islands can reduce the cost of transportation in immersed tunnels.

These deep things, he could not have mentioned a word at this morning's seminar.

But Gu Lu can comprehend it on his own.

Again, that's the same sentence.

If Gu Lu is an old expert with twenty or thirty years of experience in the field of engineering and construction, Academician Li would not be surprised at all to say those opinions.

But what?

Gu Lu is not only too young, but also a mathematics major, not engineering and architecture.

This is really surprising.

“…… Mr. Li, that's all I want to say. It took more than ten minutes for Gu Lu to briefly explain his understanding and statement, and then humbly asked, "Elder Li, since I am not majoring in engineering, what I just said must have many deficiencies, and I would like to ask Elder Li to give me advice." ”

Academician Li shook his head and smiled bitterly, "Based on what you just said, as long as you don't tell others in advance, no one will suspect that you are not an engineering student." ”

"Ji Changyi, I really envy him! With such an excellent disciple as you," Academician Li couldn't help but sigh, "With your talent, no matter which field you choose, you will inevitably become an existence at the top of the pyramid in the future." ”

Academician Li's words can be said to be a great praise for Gu Lu.

Gu Lu hurriedly got up and said that he didn't dare to be.

Academician Li waved his hand and asked Gu Lu to sit down, "That's it, don't sigh." ”

"I wanted to persuade you to switch to engineering, but I thought about it. Since I didn't meet you earlier, it's fate that hasn't arrived. Besides, no matter what field you are in, you can bring glory to the country, and I won't do this difficult thing for a strong man. ”

"Again, back to business. Although there are many personal understandings of what you just said, there are also a few places where you are not thorough, or you don't get to the point. ”

Academician Li cleared his throat, "First, each standard section of the immersed tunnel is composed of 8 small pipe sections, and the reason for this is not just for load-bearing. Hydrophobic, ventilated, break-proof, these are all causes. ”

"And ......"

Academician Li really loves talents.

Not only did he point out the deficiencies in Gu Lu's views just now, but Gu Lu then asked a few other technical questions one by one, and Academician Li did not answer the questions impatiently.

Even for a while, Gu Lu forgot to eat, immersed himself in the ocean of knowledge and swam to his heart's content, tireless.

Due to this episode in the middle, when Gu Lu finished lunch and followed the academicians back to the hotel, it was already past two o'clock in the afternoon.

When he was about to go upstairs, Academician Li patted Gu Lu's shoulder cordially, "Xiao Gu, if you have any questions that you don't understand, feel free to come and ask me." My room was upstairs. ”

"Well, thank you Elder Li. Gu Lu nodded heavily.

Back in the bedroom, Gu Lu rubbed his sour eyes, and leaned back on the chair, sitting in a paralyzed posture.

No way, I'm so tired!

Since arriving at the Bohai Sea Hydrological Research Center at eight o'clock in the morning, Gu Lu's brain has not stopped to rest.

I've been thinking, I've been understanding, I'm crazy about absorbing knowledge.

Even during lunch, I discussed professional and technical issues with Academician Li for nearly an hour.

After leaning on the back of the chair and resting for a while, Gu Lu picked up the porcelain cup, made himself a cup of coffee, sat down at the desk, and turned on the computer.

While observing the construction concept map of Academician Li, I looked up some professional literature on the Internet to confirm my thoughts.

Then, write down some doubts and incomprehensions in the notebook, and wait until tomorrow to consult Academician Li.

Although Academician Li told Gu Lu that he would go to him at any time if he encountered a problem, Gu Lu would not just go over and nag like this.

Academician Li also needs to rest, especially when they are old and sleepy when they use too much energy.

If Gu Lu encounters a question, he will ask it, and if he encounters one, he will ask it, and so on, it will definitely wear down Academician Li's good impression of himself.

Therefore, it is better to write down the questions first, and wait for Academician Li to ask for advice tomorrow.
