Suddenly, it started raining. Large raindrops fell and hit the surface of the river, making a loud pitter patter. The heavy rain was like a huge waterfall, covering the sky and covering the earth. The trees swayed wildly in the wind and rain.
Wu Shuping wanted to hold an umbrella for Li He, but Li He refused. He looked at the endless rain and said faintly, "It's raining well. I like the rain." “
Wu Shuping said, "Mr. Li, it's cold. If you get wet, you'll definitely catch a cold."
"There's no need." Li He had never felt so carefree before. His voice was clear and firm as he said, "It's better if it rains harder."
Wu Shuping wanted to say something, but Yu Dehua chased her to the side. He accompanied Li He in the rain at the bow of the boat.
Li He smiled and asked, "Are you sure you can do it?"
Yu Dehua said generously, "You said before that a man can't say no!"
Li He laughed, and so did Pinsong and Yu Dehua.
After getting ashore, the three men were all drenched.
Li He wiped the rainwater off his head and said, "Awesome!"
Although he was shivering a little from the cold, he looked at the wide river.
But looking at the wide river, there was a feeling of 'the new waves of the Yangtze River surpass the old, each wave higher than the one before'. Perhaps it was too pretentious, but he liked it. He really liked it. The rain poured on him, and his mind was clear.
What made him really happy was that the world-famous Lijiazui land now truly belonged to him.
He felt that the Lijiazui land had become so inflated that he had forgotten who he was!
Why was he so eager to make progress?
After two years of development, high-rise buildings were built, and foreigners were coming in to earn money. Oh, my, my nostrils are going to be raised to the sky!
The joy in his heart could only be described in the words of Pu Jiang!
He followed Yu Dehua into the engineering department.
The chief engineer came out to welcome them. He had followed Yu Dehua to Germany for the exhibition.
"Thank you, Mr. Yu. This has really broadened my horizons. We are even more confident this time!"
Li He only looked at the engineering drawings and did not interrupt. A complete set of architectural blueprints would have a lot of pages depending on their professional content or function. There would be a table of contents to construction drawings. Just a set of heating and ventilation drawings would have more than 700 pages, and this was only the preliminary plan.
Yu Dehua said, "It's been hard on you."
The chief worker said, "To put it bluntly, Mr. Yu, this is because you trust us. You're giving us money to practice!"
He was also very touched. This 500-600 million USD project was willfully handed over to them! He could not help but sigh with emotion! One had to know that even the Japanese had come! They even wanted to give an interest-free loan to Yuanda Group, but Yuanda Group still rejected them!
The Yuanda Group rejected the Japanese's mature plan and chose them, a team with no construction experience. What else could they say?
"There's no wind damper?" Li Hexian looked at the eight general design drawings and raised this question. When a tall building encountered a strong wind of level 6 or above, the people inside the building would feel slightly shaken. Moreover, Pujiang was often attacked by typhoons. Therefore, the buildings were specially installed with such wind dampers to provide a more comfortable environment for the people inside the building.
He was considered half an expert in mechanics. From the perspective of force analysis, he could roughly see some problems.
"Wind damper?" Gong Gong looked at Li He suspiciously. This young man had looked at the blueprints the moment he came in. He had thought that he was Yu Dehua's employee, so he had overlooked him.
Yu Dehua hurriedly introduced, "This is our Yuanda Group's chairman. This time, he specially came from Hong Kong for the Pudong project!"
"Chairman?" This name was even more unfamiliar to Gong Gong.
Yu Dehua said seriously, "He's my boss! Do you understand now? "
"Boss?" This time, Gong Gong could not believe it! He looked at Yu Dehua and then at Li He. One was old and steady! The other had no hair on his mouth! However, looking at Yu Dehua's serious expression, it did not seem like he was joking! He awkwardly extended his hand towards Li He and said, "Director Li, nice to meet you. Welcome!"
Yu Dehua pointed at the chief engineer and said, "This is the chief engineer, Mr. Zhu Guohao."
Li He also extended his hand and said, "Thank you! Just call me Li He. My hometown is Wanbei. "
"You're from China?" After Zhu Guohao said that, he felt that his wording was a little wrong, so he added, "Chairman Li, are you from China?"
Li He smiled and said, "I guarantee it. Shall I show you my ID? "
"No need! No need! "Zhu Guohao said excitedly! Could this be considered the first skyscraper that China had invested in and built themselves?
This had risen to another level!
The meaning was completely different!
He continued to ask, "Chairman Li, what kind of wind damper were you talking about? I've really never heard of it. "
As an engineer who had never heard of it, he felt a little ashamed.
"Never heard of it?" Li He frowned, feeling a little incredulous. Could it be that wind dampers were not used on skyscrapers at this time? He asked, "Do you know about the bridge dampers?"
Damper is a device that provides resistance to movement and reduces movement energy.
The use of damping for energy absorption and shock absorption was not a new technology. Various dampers had long been used in aerospace, aviation, military, firearms, automobiles, and other industries. From the 1970s, people began to gradually transfer these technologies to building, bridge, railway and other structural engineering, its development is very rapid.
In particular, the hydraulic viscous damper, which had a history of more than 50 years, had undergone a large number of experiments, strict reviews, and repeated demonstrations before it was accepted by the structural engineering community in the United States.
Zhu Guohao smiled and said, "Chairman Li, are you talking about the shock absorbers?"
"That's right." Li He suddenly understood. It was probably because the names were not the same.
Zhu Guohao said, "Mr. Yu's current bid winner is a Canadian company. They only gave him a preliminary design. The complete design would have to wait until New Year's Day. And we.
Have talked to the Canadian designer, and they did not mention any shock absorption measures. "
Li He shook his head and said, "There must be a wind damper."
Whether there was one or not, it would be a completely different experience in terms of comfort.
He still explained the principle of the wind damper to Zhu Guohao in detail.
The damper was not anything fancy. In fact, it was a giant pendulum formed by a mass block and a suspension cable. It resonated with the main structure and could reduce the shaking of the building. Later on, it was a little more complicated. It was a damping system that used eddy current technology to reduce the amplitude of the mass block and consume the input energy of the wind.
Zhu Guohao was shocked by Li He's attainments in mechanics. He gave him a thumbs up and said, "You really are an expert in this field!"
