The bustle of Bokan City didn't have much of an impact on Bokan Military Academy, except that the students felt a little different when the engineering and medical departments were separated. It's all going on quietly.

On the weekend, Liu Yu came to the huge construction site outside Bokan City early. I only saw that the construction site was crowded with people, and it was very lively, and all the people were busy working. Halfway through the project, spacious and bright factories are neatly arranged. The unloading of ships on the dock is in good order, and workers are moving boxes of goods to the factory. Looking at the busy people in front of him, Liu Yu couldn't help but be enthusiastic.

walked in quickly and came to Zhang Wenyu's office. There was a knock on the door, but no one answered. So Liu Yu pushed open the door and walked in. The office was also busy, with several people arguing fiercely around a large table.

Liu Yu stepped forward and saw a drawing spread out on the table. A man gestured on a drawing and said, "This is the way it is now. According to the design requirements, the daily output of each blast furnace is 20,000 catties. In order to achieve this goal, there are certain requirements for the size, speed and air supply volume of the blower. The size of the blower designed to meet the requirements is too large for human labor to operate properly. The speed and air volume are not up to the design requirements. Now it is necessary to find the power that will drive the wind turbine or reduce the output of the blast furnace to reduce the size of the fan. Let's discuss it and see if there are any good suggestions. ”

For a moment, everyone fell into deep thought, and the office suddenly fell silent. After a while, Zhang Wenyu said: "The output of the blast furnace must not be reduced. If we reduce production, we will not be able to keep up with the amount of steel used in our plants, which will seriously affect our follow-up plans, and we will not be able to talk about the large-scale development path we envisioned. Zheng Gong, this problem must be solved as soon as possible, no matter what way you think. If there is a delay here, the rest of the work will not be able to begin. ”

"It's too difficult, the deadline is tight, the technical difficulty is huge, and I think it's difficult to find an alternative power source in a short period of time. Zheng Zhi frowned and shook his head.

"I have an idea, I don't know if it's feasible?" Seeing that everyone was silent, Liu Yu said.

"Who are you and how did you get in?" Hearing the voice, Zheng Zhi raised his head and saw a stranger and couldn't help but say angrily, "We are discussing important matters, how can we let the idle people in? Quickly get him out!"

"Zheng Gong, don't get angry yet. He is the Liu Yu I mentioned, and he is also a member of our plan. Let's see if he can do anything good. Seeing that it was Liu Yu, Zhang Wenyu hurriedly explained.

After listening to Zhang Wenyu's explanation, Zheng Zhi's anger was a little less: "Then you can tell me, if it's just a waste of our time, I'm going to kick you out." ”

Liu Yu nodded to Zhang Wenyu first, and then said: "Our current plan is to improve productivity and accelerate the production of materials, so the equipment must be large-scale to meet the demand, and it is difficult to rely on manpower alone." My suggestion is to harness the power of nature to convert the energy generated by the flow of water in nature into a controllable energy source that we can use to achieve our ends. ”

"Your idea is very good, the power of water is huge, but at the same time it is violent, how can we control the water for my use?" Zhang Wenyu asked with a frown.

Liu Yu was about to answer, but Zheng Zhi stretched out his hand to interrupt him: "Wait, let me think about it." After a while, Zheng Zhi instructed: "Li Bai, you went to find the hydrological data of the Bokan River basin of the Changqing River for nearly ten years and measured the flow rate of the Changqing River on the spot. Chen Hui, you go and measure the topography and vertical drop on both sides of the Changqing River. Before the end of the day, the data will be summarized to me, and the rest of us will go back to make preparations. As soon as the data arrives, we will design a plan overnight, and we will start work early tomorrow morning, so let's go back and prepare. ”

"Yes," everyone replied, and they left to make preparations.

In the blink of an eye, only Liu Yu, Zhang Wenyu and Zheng Zhi were left in the office. Zheng Zhi looked at Liu Yu and said, "Thank you, little brother, for reminding me." It opened my mouth suddenly, and my thinking has broadened a lot, and I hope you can give me advice if you don't understand anything in the future. ”

Liu Yu waved his hand and said: "Zheng Gong is smart and talented, it should be that I learn more from you." ”

After listening to the words of the two, Zhang Wenyu laughed: "You don't want to praise each other anymore, as long as the project can be completed on schedule, you have made a great contribution." ”

Zheng Zhi looked at the time and said to Zhang Wenyu: "Elder Zhang, you talk slowly, I'll go to the construction site first." After speaking, he bowed his hand to Liu Yu and left in a hurry.

After Zheng Zhi left, Zhang Wenyu said to Liu Yu: "This Zheng Zhi is a good hand in construction, plus he has a team to assist, so our project can progress so quickly." But I still don't understand what you're going to do?"

Liu Yu said: "This person is really smart, I just raised my head, and he can understand what I mean." The impact of the water flow is very powerful, and the use of the water flow to drive the operation of the blower can not only obtain strong power but also save manpower. Harnessing the energy of nature is the only way to make us stronger. ”

Zhang Wenyu nodded: "I'm relieved." It's your first time here, so I'll familiarize you with it first, so you can know it in your heart. ”

In the evening, Li Bai and Chen Hui came back one after another. A group of people gathered in the office again. Li Bai first said: "The flow rate of the Changqing River is 100,000 cubic meters per second. Observations in the last decade show that the Changqing River has the largest flow in summer, with a peak of about 173,000 cubic meters and an average of 156,000 cubic meters. In winter, when the dry season begins, the minimum flow is 60,000 cubic meters, and the average is about 80,000. There have been three floods in ten years, which have brought great disasters to the people of Bokan City. I have recorded the details in this dossier, so you can take a look at them. After speaking, he handed a thick paper bag to Zheng Zhi.

Chen Hui then said: "I measured the river bank line of ten miles upstream and downstream of our construction site, and the Changqing River generally showed a trend of high in the west and low in the east. Our site is located in a plain on the north bank of the Changqing River, with hilly terrain to the northwest of the site. There is a clear downward trend in the flow of the Changqing River, where the flow is rapid, and further downstream, it tends to flatten. Here is the topographic map. With that, he unfolded a drawing and spread it out on the table.

The drawings are drawn at a 50:1 scale, clearly depicting the topography of the north bank of the Changqing River and the drop of the river. After reading the topographic map and reading the dossier that Li Bai brought back, Zheng Zhi pointed to a place on the topographic map and said: "My idea is to build a dam here to store water, and when the water surface reaches a certain height, open the gate to release water, and use the impact of the water flow to drive the blower to operate." That's how you design it. ”

Everyone began their own work, and the design of the dam, the design of the blast furnace, and the design of the transmission mechanism performed their respective duties and began to work heavily. By the time the first rays of sunlight rose in the morning, the design work had been completed and preparations for the truncation of the Evergreen River began.
