On the third day after Li Huayong and others arrived in Shencheng, Jitong University's "Civil Engineering Disaster Prevention Laboratory", which is a national key laboratory, .

Five or six graduate students sat in a circle, where they wrote and drawn, while Lao Qian paced back and forth in the lab with his hands behind his back.

Old Qian's expression looked a little tangled, as if he had encountered some problem, and he paced back and forth while chattering;

"How is this possible? How is this possible!"

Don't make a mistake, it's not that he found anything wrong with the "invertebral method", in fact, when Professor Qian read the whole plan in its entirety for the first time, he was overwhelmed by the clever design of the plan, and intuitively he knew that the solution was feasible.

After all, it is a national laboratory, and Professor Qian's team only took less than a day and a half to completely prove the safety and feasibility of this construction method.

Now what really makes Lao Qian struggle is the last item: the problem of program optimization.

Just as Lao Qian was pacing back and forth, a young man with glasses stood up, this must be Lei Yutong's senior brother, let's call him "Senior Brother A".

"Senior Brother A" came to Lao Qian's side: "Professor Qian, look at me to modify it like this"

Lao Qian took the drawings handed over by "Senior Brother A", and only two minutes later:

"Well, I understand your intention to increase this steel platform, which seems to increase the safety factor, but have you ever thought about the lifting of this steel platform? According to your design, how thick does this steel strand have to be used to pull such a big guy? And how are you going to solve the support problem of this big guy? Where are you going to choose? How much force does this place need to suffer? You, you, you go and look at other people's original plan, are you optimizing other people's plan or degrading other people's plan? ”

"Senior Brother A" was blushing by Lao Qian's series of rhetorical questions:

"I, I'll go back and think about it. ”

"Senior Brother A" was defeated, and "Senior Brother B" came up.

Professor Qian's tongue became more and more poisonous: "You are, I now suspect that you have not understood the essence of this design, the inverted vertebrae, the reason why people call this construction method the inverted vertebrae, its core idea is to form a steel group into a box-shaped, similar to a cone, and then pour concrete." Engineering is not taken for granted, I have told you many times. I'm asking you now, can you imagine if this method is really used in construction, then what is the biggest difficulty in implementation?"

"Like,."

Then you compare your modification with the original plan of others, who are doing everything possible to consider how to facilitate the pouring of concrete, and you, to put it mildly, you are doing everything possible to increase the difficulty of concrete construction. You're embarrassed to show someone something like that?"

"Senior Brother B" also had a gorgeous retreat, followed by "Senior Brother C", "Senior Brother Ding"

This is the reason why Lao Qian was entangled, he didn't start to optimize the plan, but after he really started this step, he found that the original plan submitted by Li Huayong and others was not good.

What does it mean to have a solution that has been proven to be safe and feasible and can no longer be optimized?

Lao Qian was entangled in his heart, he didn't have seen an excellent construction method, but he thought that such an excellent construction method was actually from the hands of a "Huaqing" graduate, and the young worker next to him who seemed to be honest and harmless, after knowing that these two were the main designers of this construction method, Lao Qian himself didn't know why, and he always felt uncomfortable in his heart.

"What about Xiao Li? Where is that Xiao Li from Huaxia Jianzong now? Who is going to invite him over, I have something I want to communicate with him. ”

"Senior Brother A, B, C, and D" looked at each other one by one, not because they heard Professor Qian actually use the word "exchange", but mainly because Li Huayong and Li Er were both surnamed Li, and everyone couldn't figure out which one Lao Qian was talking about.

"Is it Senior Brother Li from Huaqing? He seems to have gone to Wenyuan Tower again today, or I'll call him now." ”

Old Qian glared:

"What do you call him for? In the past two days, have you not found that the worker is the soul of designing this construction method? I have a feeling that his understanding of this construction method is much more thorough than that of the Huaqing graduate. So if I'm not mistaken, this is probably the main designer of this method. ”

The "Senior Brothers, A, B, C, and D" looked at each other one by one again. Old Qian's words simply subverted their outlook on life.

To demonstrate the safety of a construction method, of course, there must be a specific object, which is inseparable from the specific construction drawings.

The Bank of China Building is still bidding, and it is impossible for Li Huayong and others to bring so many drawings to Shencheng, and there is not even an electronic version in this era. Therefore, when Professor Qian and others were busy these days, Li Huayong and Li Er were not idle, and they also needed to provide a lot of specific parameters of construction drawings for demonstration.

Fortunately, Li Huayong was prepared, and he did the preparation before he set off, and took the design parameters that he thought might be used in a thick notebook to Shencheng. Therefore, in the past few days, whether it is Professor Qian or "Senior Brother A, B, C, and Ding", they have all had contact with Li Huayong and Li Erzi.

Now Lao Qian actually said that Li Huayong may be the main designer of this construction method, which is of course completely unexpected by the "senior brothers".

"By the way, what are they doing today, why didn't they come over?" asked Lao Qian again.

"Senior Brother Li from Huaqing is giving a report to the first and second grade students today. ”

"Senior Brother A" explained: "After they came, the school learned that the two of them actually participated in the construction of the "Pengcheng World Trade Center" and were the witnesses at the forefront of the "Three Days and One Floor". After learning about this situation, our Department of Civil Engineering decided to ask them to make a report and tell the junior students about specific construction examples. ”

"Oh, and that kind of thing?"

A smile hung on the corner of Lao Qian's mouth: "Listen to the front-line personnel talk about the specific construction, this method is very good and necessary, not only for the junior students, but I think you should listen to it even more." In that case, I don't think this solution can be optimized by relying on us alone, so let's go and hear their report. All of them are going, and I am going too. ”
