Otaku Engineer in Great Tang Dynasty

"The waterwheel is actually like a big turntable. You can use wooden poles as the skeleton of the turntable, or steel. The edge of the turntable is equipped with a scraper and a bucket. The water flow will drive the scraper to rotate, and when the scraper rotates , The water bucket is filled with water, and as the waterwheel rotates, it is raised one after another. At the top of the waterwheel, the water bucket is rotated by gravity, and the water in it will be poured into the tank above the waterwheel. , So the cycle goes back and forth, and the process from holding water to transporting water is completed.

Among them, the direction the water bucket faces is very important. It must be against the direction of the water flow. Only in this way can the river water be lifted to a high place. In addition, the main wheel of this waterwheel needs to be used. The unique roller bearing of the workshop reduces friction and improves the efficiency of transporting river water! Of course, for those stagnant water that does not flow, you can add a gear transmission mechanism to it, and use animal power to drive the wheel to rotate!

Either way, it is much more convenient than the previous manual rollover~! "

In the afternoon, Li Zexuan brought the drawn drawings to the Qiqu Pavilion workshop. Yan Shaoning, Fu Bo, Mo Huai, and Mo Chui all rushed over after hearing the news. Li Zexuan spread out the drawings and explained the structure and operation principle of the waterwheel. Tell everyone carefully.

"Excellent workmanship! In this way, as long as there is water in the river, this waterwheel can carry the water up to the shore day and night, and if there are several such waterwheels side by side on a section of the river, the water transfer speed is absolutely sufficient. Thousands of acres of farmland have been irrigated in a short time!"

After listening, Mo Huai imagined the waterwheel running in his mind. At the end, he couldn't help but stroked his beard and exclaimed.

"That's right! Compared with the previous manual dump truck, this kind of water truck can automatically carry water as long as it is placed on the river surface. It is not only convenient and labor-saving, but also has a large water output! You can use this to transport the river water to the ditches, so Once there, I no longer fear drought~!"

Uncle Fu couldn't help but nodded.

Li Zexuan smiled and said, "You are right. This waterwheel is equipped with ditches and can be used for large-scale farming instructors! Tomorrow I will go to Madam He to hurry up and use cement to fill the ditches in Lantian County. All renovations are done again. Lantian County has a dam as a guarantee. Water can be discharged directly from the reservoir into the ditches. For the villages in Lantian County near to the north, because the terrain is much higher than this side, a waterwheel can be used there. Bring the water over!"

The terrain of Lantian County is higher in the north than in the south, and higher in the west than in the east. The Bahe is a river that merges from the northwest into the main course of the Yellow River in the southeast. The villages close to Bahe such as Meicun and Hanjiazhuang are directly drawn from the dam. A canal can guarantee that all the farmland can be irrigated. However, a canal close to the north of Zhuangzi like Yujiazhuang, wanting to use a canal to lead the Bahe River to the past is no different from wishful thinking. The water in the ditches in the south is carried to the north!

"Use cement to repair the ditch? Xiaoxuan, I heard that right?"

Yan Shaoning couldn't help widening his eyes when he heard the words, and said in an unbelievable burst.

Fu Bo, Mo Huai, and Mo Chui all looked at Li Zexuan in surprise at this time. They probably felt that Li Zexuan had just made a mistake by accident!

Li Zexuan nodded and said: "Yes! That's right! It is to renovate the ditch with cement! First, the ditch built with cement can reduce the loss in the process of water flow. Second, compared to the previous mud ditch, cement ditch It is more convenient for maintenance and does not need to be dredged every year. The saved manpower and material resources are too cost-effective compared to the amount of cement."

Yan Shaoning nodded thoughtfully, and said, "That's the truth, but such an extravagant method can only be used by Lantian County~!"

The construction of canals in other places is just a matter of hiring some civilians to put in some effort, but unlike Li Zexuan, he has to pay for both labor and cement materials!

"Hehe! These efforts are definitely worth it~!"

Li Zexuan said with a smile, then looked at Uncle Fu and said, "Uncle Fu, you have also read this drawing. I wonder if there are any technical difficulties in it?"

Fubo thought for a while, then shook his head and said, "There is no difficulty. Some of the techniques used in it are all ready-made in the workshop. If the old man can't even look at the drawings, there is no place for this old face. That's it! Master, rest assured that the workshop will make the waterwheel as soon as possible, and then you can test it right away!"

Li Zexuan nodded. With the current technical level of the workshop, it is indeed not difficult to manufacture this waterwheel. He smiled and said, "Good! I have been working hard recently. The drought is like a fire. Let's make the waterwheel earlier. , The people can suffer one day less!"

"Master (Shanchang) don't worry, I will do my best~!"

Fu Bo, Mo Huai, and Yan Shaoning all knew the importance and sternly clasped their fists.

Li Zexuan nodded, said goodbye to everyone, and left the workshop.

..................................

It's already evening when we leave the workshop, and we can see people who are still watering the fields everywhere. In this era, water conservancy projects are far from being as developed as in the past. Large projects like the renovation of water canals, if there are no county officials presided over. Basically, no one will take care of it. Those abandoned canals will become clogged again under the scouring of rain for many years. Cleaning up is very troublesome. Basically it is the same as the amount of work required to re-excavate a canal. almost!

This is one of the reasons why Li Zexuan insisted on renovating all the canals in Lantian County with cement!

"Master~!"

Coincidentally, not far after leaving the workshop, he ran into Hu Hanyun holding a bucket.

Since Han Li was a "landlord" in Lanzhou, Hu Hanyun has become the Xinlizheng of Hanjiazhuang. Lao Hu was a man of love and justice. He took his wife and fled to Hanjiazhuang, many of the villagers in the turmoil. He has helped him before, and now he is the Lizheng of Hanjiazhuang. He is even more conscientious and dare not slacken for a day. When the one on the Zhuangzi encountered a problem, he was always the first to solve it quickly. The dealers of Hanjiazhuang told Hu Hanyun Of course, there is nothing to say.

"Uncle Hu, are you just coming back after pouring the water?"

Li Zexuan asked with a smile.

Hu Hanyun wiped his sweat and grinned: "Isn't it! It has been dry recently, and the nutrient bowl in the ground has just been planted. If you don't pour some water, it is estimated that the white stack will not survive even if it germinates! This thing is precious." Now!"

Not only Lao Hu, the people in Lantian County are busy "watering the flowers" recently, watering the white dilapidated flowers that have just been planted in the ground. This thing was bought by Li Zexuan at a high price. No one does not take it seriously. An acre of white fold seed flowers is more expensive than all the crops of each of their families. If a good harvest can be obtained, it will basically be a year of eating and drinking!

Li Zexuan was clear in his heart. He thought about it and said, "Uncle Hu, you will tell the villagers in a moment that the ditches in our county will be dredged soon, and there will be no need to carry water and irrigate the ground. !"

Hu Hanyun widened his eyes with surprise, and said, "Master, what you said is true? Does the county help us clear the ditches?"

Li Zexuan smiled and said: "Naturally, it is true! Within a few days, the county government will organize civil servants to start the work. If the dealers have some free time, they will help the workers. This can speed up the progress and get a share. Wages!"

Old Hu hurriedly waved his hand and said, "Eh! Master, what does not work? Anyway, we help us build the ditches by ourselves. We should do our best! Don't worry, you will not work. As long as the dealers are motivated, they will go there to help. We don't have anything else, but we still have this strength!"

The ancient people were simple and honest. As long as the officials were willing to organize everyone to clear the ditches together, they were willing to do it without wages. Besides, ordinary ordinary people in ancient times were generally in slavery, and doing these things can reduce part of the labor. Why not help your own farmland irrigation?

Li Zexuan smiled, and said: "Uncle Hu, there will be some money for this, but not too much. After all, the amount of money that can be paid in advance in the county is also limited, but at least it will still take care of the food. Let’s call on those half-elder children who can lift a shovel and eat a lot more often, and they can eat a full meal after helping out, right?"

This is not the use of child labor. In ancient times, he was considered an adult at the age of thirteen or four. At this time, the children of ordinary people were generally not fat, because they could not eat every meal until they hiccup. It’s a good idea to eat for a few more days while working as a helper!

Hu Hanyun grinned and said: "Make! Make! This make! Those little bastards, squatting in Zhuangzi every day and not doing serious things, letting them help out is a good way to hone their temperament!"

Li Zexuan smiled unavoidably, then chatted with Hu Hanyun two more gossips, and then left.

It was getting late today, so he didn't plan to go to the county seat, and went straight back to Yunshan.

………………………………

In the morning of the next day, after Li Zexuan finished his exercises and breakfast, he went straight down the mountain and headed towards Lantian County.

In order to prepare for the big wedding of Pang Fei Gene, Li Zexuan let him off for a few days, so he did not come with him today. The two brothers Liu Feng and Liu Yun are now with Li Zexuan!

Li Zexuan is now a millionaire, and he has to be accompanied by a security guard when he goes out. Not to mention his safety, he is also a party!

It is said that the two brothers came from the Forbidden Army. They were originally sent by Li Er to help Li Zexuan look for mines and act as guards by the way. However, Li Zexuan has been busy with vanadium mines, dams, and drought relief recently. It is not clear what mine should be mined next. So they didn't arrange a mining task for the two of them, and the two temporarily acted as guards.

Entering the county seat of Lantian County, Li Zexuan headed directly towards the county office. When passing by another street next to the county office, Li Zexuan inadvertently caught a glimpse of a luxurious mansion with Yongan Houfu written on it. He couldn't help being stunned. Obviously, secretly this should be his new mansion in Lantian County!

I’m ashamed to say that he heard from the county magistrate that the new mansion was built, but he hasn’t had time to go in and take a look. After that, the decoration and furniture purchase in the new mansion were all handled by his father and mother. Apart from paying for it, it can be said that no contribution has been made to this new mansion!

However, from the outside, this new mansion is more stylish than the one in Chang'an. At the very least, the two stone lions at the door are very luxurious, and Li Zexuan likes it!

Yunshan Bieyuan is a modern style small building, suitable for short stays and vacations, and this mansion in Lantian County can be regarded as a formal Hou Mansion, which has symbolic significance and symbolizes that the owner of Lantian County is the residence. Here, the architectural style of this mansion is authentic Tang-style architecture.

I have lived in Yunshan Bieyuan for more than half a year. If I change back to a mansion in the Tang Dynasty style, it might be good!

Li Zexuan wondered in his heart, and after a while from the county government, he had to go to the new house to see. He didn't aspire to be a wise man like Dayu, and he couldn't do such a thing three times without entering the house!

In other words, if this luxurious mansion is left in the modern era, it would have to sell for billions, right? However, Li Zexuan spent less than ten thousand sticks before and after, to build such a luxurious mansion, thinking about it, I feel a little dreamy!

Even so, it is estimated that some people may say that he is extravagant, but for Li Zexuan, he has made so much money, can't he still enjoy it and make his family live better? Besides, he is not the kind of person who is not benevolent for wealth. He himself can't count the examples of him paying for his own money and driving the people to get rich!

"Master Hou, shall we go in and sit down? The master and the old lady should all be up right now!"

Liu Feng saw that Li Zexuan looked at the mansion in front of him for a long time, and he suggested it.

Li Zexuan came back to his senses and shook his head: "Business matters are important, go to the county office first!"

After all, he urged Da Bai to walk towards the county office.

Arriving at the county office~www.readwn.com~ Li Zexuan didn’t let anyone pass it on. He went directly to the post office. At this moment, the county magistrate He was just at the post office reviewing the official document. Seeing Li Zexuan suddenly came, he was shocked and wondered. Is it because I haven't done a good job lately, so Li Zexuan came to ask the crime himself?

After pressing down on the doubts in his heart, He county magistrate hurriedly greeted him and said, "The official has seen Lord Hou!"

"Hmm~!"

Li Zexuan nodded and walked into the hall, and then he asked: "Major He, the weather has been dry these days, and many crops in the fields have withered, do you know?"

The county magistrate He was startled, and then he understood Li Zexuan’s intentions. He hurriedly said, "Going back to Lord Hou, the subordinate official has already known about this matter, and two days ago, the subordinate official has already discussed the solution with the county prime minister and the master book in Yali. As for the plan, we decided to gather the people in the villages, dredge the ditches, and then divert water from the dam built by you. The official originally planned to discuss the matter with you today. I didn’t expect you to come to the county office so soon. !"
