"A waterwheel is actually like a big turntable. You can use wooden poles as the skeleton of the turntable, or you can use steel. There are scrapers and water buckets on the edge of the turntable. The water flow will drive the scrapers to rotate, and when the scrapers rotate, , the water bucket is filled with water, and is lifted up section by section as the water wheel rotates. When it reaches the top of the water wheel, the water bucket rotates due to gravity, and the water in it will be poured into the water tank above the water wheel. , and so on, 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, we must use the main wheel of the water wheel. The unique roller bearings of the workshop reduce friction and improve the efficiency of transporting river water! Of course, for those stagnant water, you can add a gear transmission mechanism and use animal power to drive the wheel rotation!
No matter which method is used, it is much more convenient than the previous manual car rollover~! "
In the afternoon of that day, Li Zexuan brought the drawings to the Qiquge 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. I told everyone carefully.
"What a wonderful work! In this way, as long as there is water in the river, this waterwheel can carry the river water to the shore day and night. And if there are more waterwheels like this on a section of the river, the speed of moving water will definitely be enough. Thousands of acres of fertile farmland were irrigated in a short period of time!”
After listening, Mo Huai imagined the scene of the waterwheel running in his mind. At the end, he couldn't help stroking his beard and praised.
"That's right! Compared with the previous manual overturned trucks, this kind of water truck can automatically transport water as long as it is placed on the river. It is not only convenient and labor-saving, but also has a large water output! You can use this to transport river water into ditches, so Once you come here, you won’t be afraid of drought anymore~!”
Fu Bo couldn't help but nodded.
Li Zexuan smiled and said: "You are right. This water tanker coupled with ditches can completely carry out large-scale farmland training! Tomorrow I will ask County Magistrate He to seize the time and cement the ditches in Lantian County. All are renovated. Lantian County has a dam as a guarantee, and water can be released directly from the reservoir into the ditch. For the villages near the north of Lantian County, since the terrain is much higher than here, water trucks can be used there to transport the water. Bring the water over!"
The terrain of Lantian County is higher in the north than in the south, and in the west than in the east. The Bahe River is a river that flows from the northwest into the main channel of the Yellow River in the southeast. Zhuangzi such as Meicun and Hanjiazhuang, which are close to the Bahe River, are directly drawn from the dam. A canal can ensure that all farmland can be irrigated. However, if Yujiazhuang is close to Zhuangzi in the north, it is tantamount to wishful thinking to use canals to divert water from the Bahe River. The only way to do this is to rely on waterwheels. The water in the ditch in the south is carried to the north!
"Renovate ditches with cement? Xiaoxuan, did I hear you correctly?"
When Yan Shaoning heard this, he couldn't help but widen his eyes and said in disbelief.
Uncle Fu, Mo Huai, and Mo Chui all looked at Li Zexuan in surprise at this time. They probably thought that Li Zexuan had accidentally said something wrong just now!
Li Zexuan nodded and said: "Yes! That's right! We need to renovate the ditch with cement! Firstly, the ditch built with this kind of cement can reduce the loss during the flow of water. Secondly, compared with the previous mud ditch, the cement ditch It is more convenient to maintain and does not need to be dredged every year. Compared with the little cement consumed, the manpower and material resources saved can be said to be very cost-effective~"
Yan Shaoning nodded thoughtfully and said: "That's the truth, but only Lantian County can afford such a luxurious method~!"
In other places, building canals is just a matter of hiring some civilians to put in some effort, but unlike Li Zexuan, you have to pay for both labor and cement materials!
"Haha! All 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. Are there any technical difficulties in it?"
Uncle Fu thought for a while, then shook his head and said: "There is no difficulty. Some of the techniques used are all ready-made in the workshop. If the old man can't even look at the drawings, then there will be no place for this old face." Don’t worry, young master, the workshop will make the waterwheel as soon as possible, and then you can start testing it right away!"
Li Zexuan nodded. With the current technical level of the workshop, it is indeed not difficult to make this waterwheel. He smiled and said: "Okay! It's been a lot of hard work recently. The drought is like a fire. Let's make the waterwheel earlier." , the common people will be able to suffer one less day!"
"Don't worry, young master (mountain leader), we will do our best~!"
Uncle Fu, Mo Huai, and Yan Shaoning all knew the importance and solemnly clasped their fists after hearing this.
Li Zexuan nodded, said goodbye to everyone, and left the workshop.
.....................................
When we left the workshop, it was already evening, and people could be seen everywhere outside still watering the fields. In this era, water conservancy projects were far from as developed as in previous generations. Major projects such as the renovation of canals would not have been presided over by county officials. , basically no one will ever do it. Those abandoned ditches will become clogged again under the erosion of rain for many years. Cleaning them is very troublesome. It is basically the same as the amount of work to re-excavate a ditch. almost!
This is one of the reasons why Li Zexuan insisted on renovating all the water canals in Lantian County with cement!
"Master~!"
As luck would have it, not long after leaving the workshop, I met Hu Hanyun carrying a bucket.
Since Han Li became a "landlord" in Lanzhou, Hu Hanyun has become the new leader of Hanjiazhuang. Old Hu is a man who values friendship. When the world was in chaos, he fled to Hanjiazhuang with his wife and children. Many farmers in the village They all helped him before, and now that he has become the leader of Hanjiazhuang, he is even more conscientious and does not dare to slack off for a day. When something happens to the villager, he is always the first to solve it quickly. The farmers of Hanjiazhuang treat Hu Hanyun Of course, there is nothing to say about the reputation.
"Uncle Hu, have you just come back from watering?"
Li Zexuan asked with a smile.
Hu Hanyun wiped his sweat and grinned: "That's right! It's been dry recently, and the nutrient pots in the ground have just been planted. If you don't water them, I guess the white seeds won't survive even if they sprout! This thing is very valuable. It’s here!”
It's not just Lao Hu. People in Lantian County have been busy "watering flowers" recently, watering the white flowers that have just been planted in the ground. Li Zexuan spent a lot of money to buy this thing. No one doesn't pay attention to it. It can be said that this An acre of white flowers is more valuable than the crop land owned by each family. If they can get a good harvest, they will basically have food and drink for a whole year!
Li Zexuan understood. He thought for a while and said: "Uncle Hu, tell the villagers soon that the ditches in our county will be dredged soon. Then there will be no need to carry water all the way to irrigate the fields." !”
Hu Hanyun's eyes widened in surprise and he said, "Master, are you telling the truth? Will the county help us clear the ditch?"
Li Zexuan said with a smile: "Of course it's all true! In a few days, the county government will organize civilian workers to start work. If the villagers have some free time, they can help out. Not only will it speed up the progress, but they will also get a share of the work. Wages!”
Lao Hu quickly waved his hand and said: "Hey! Master, what kind of labor is not paid? Anyway, we are helping us build the ditch ourselves. It is right for us to contribute! Don't worry, I won't give you any instructions when the time comes. As long as the dealers have the motivation, they will go and help. We don’t have anything else, but we still have the strength!”
The people in ancient times were simple and honest. As long as the officials in the government were willing to organize everyone to work together to clear the ditches, they were willing to do it even if they didn't need to be paid. Besides, ordinary people in ancient times were usually engaged in corvee labor. If they did these things, they could reduce part of the labor force. It can also help irrigate your own farmland, why not?
Li Zexuan smiled and said: "Uncle Hu, you will get some salary, but not too much. After all, the money that the county government can advance is limited, but at least you can take care of the food. When the time comes, you will let the banker If we call in those half-year-old children who can lift a shovel and usually eat a lot, they can have a full meal after helping out, right?"
He is not considered to be using child labor. In ancient times, one was considered an adult at the age of thirteen or fourteen, and at this time, the children of ordinary people were generally not fat, because they could not eat every meal with big fish and meat until they burped. It’s not a bad idea to take advantage of the opportunity of helping out to eat for a few more days!
Hu Hanyun grinned and said: "Envoy! Envoy! This envoy! Those little bastards squat in the village every day and do nothing serious. Letting them come to help is also a good way to hone their temperament!"
Li Zexuan smiled incredulously, chatted with Hu Hanyun for a few more words, and then left.
It was getting late today, so he didn't plan to go to the county town and went back to Yunshan directly.
…………………………
Early the next morning, after Li Zexuan finished practicing his martial arts and had breakfast, he rode directly down the mountain and headed towards the county seat of Lantian County.
Because Pang Feiji was preparing for his wedding, Li Zexuan gave him a few days off, so he did not come with him today. Now with Li Zexuan are the two brothers Liu Feng and Liu Yun!
Li Zexuan is now a noble man of ten thousand households, and he must be accompanied by guards no matter what he goes out. Not to mention for safety reasons, he still has a good reputation no matter what!
It is said that these two brothers are from the Forbidden Army. They were originally sent by Li Er to help Li Zexuan search for minerals and serve as personal guards. However, Li Zexuan has been busy with vanadium mines, dams and drought relief recently, and he still doesn't know what mine he should mine next. Since there was no prospecting mission assigned to the two of them, the two temporarily acted as bodyguards.
Entering the county seat of Lantian County, Li Zexuan headed directly towards the county government office. When passing by another street next to the county government office, Li Zexuan inadvertently caught a glimpse of a luxurious mansion with the name Yong'an Houfu written on it. He couldn't help but be startled by it, and then his heart Obviously, he secretly thought that this should be his new residence in Lantian County!
I am ashamed to say that I heard from Magistrate He that the new mansion was built, but he has not had time to go in and take a look until now. After that, his father and mother took care of the decoration and furniture purchase of the new mansion. Apart from spending money, it can be said that I have not made any contribution to this new mansion!
But judging from the appearance alone, this new mansion is much more grand than the one in Chang'an. At least the two stone lions at the door look very wealthy, and Li Zexuan likes it very much!
Yunshan Villa is a modern-style small building, suitable for a short stay and vacation, and this mansion in Lantian County can be regarded as an official marquis mansion. This has symbolic meaning, symbolizing that the owner of Lantian County is the one who lives in Lantian County. Here, the architectural style of this mansion is an authentic Tang style architecture.
After living in Yunshan Villa for more than half a year, it might not be a bad idea to switch back to a Tang Dynasty style mansion!
Li Zexuan was thinking in his heart. He had to go to the new house to see the new house after he finished his duties at the county government. He didn't aspire to be a wise man like Dayu. He couldn't do such a thing without entering the house three times!
Speaking of which, if this luxurious mansion were left in modern times, it would have to be sold for several billions, right? But Li Zexuan only spent less than 10,000 yuan to build such a luxurious mansion. Thinking about it, it feels a bit dreamy!
Even so, 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 let his family live better? Besides, he is not the kind of person who is unkind for the sake of wealth. He has countless examples of him using his own money to help people get rich!
"Master Marquis, why don't we go in and sit down? The master and the old lady should be up by now!"
When Liu Feng saw Li Zexuan looking at the mansion in front of him for a long time, he suggested something.
Li Zexuan came to his senses, shook his head and said: "Business matters, let's go to the county government first!"
After that, he urged Dabai and walked towards the county government office.
When he arrived at the county government office, Li Zexuan went directly to the back office without letting anyone know. Magistrate He happened to be reviewing official documents in the back office at the moment. He was surprised when he saw Li Zexuan suddenly arriving. He wondered what he had done recently. No, that’s why Li Zexuan came to ask questions in person?
Putting aside the doubts in his heart, County Magistrate He hurriedly came forward and said, "I have seen the Marquis before!"
"Hmm~!"
Li Zexuan nodded, walked into the hall, and then asked: "County Magistrate He, the weather has been dry recently, and the crops in many fields have withered. Do you know?"
Magistrate He was startled, and then he understood Li Zexuan's purpose. He quickly raised his hands and said: "Go back to the Marquis, I already know about this matter, and I have discussed it with the county magistrate and the chief registrar of the Yamen two days ago." Plan, we decided to gather people from all villages, dredge the ditches, and then divert water from the dam built by Mr. Hou. The official originally planned to go to Mr. Hou to discuss the matter today, but he did not expect that Mr. Hou would come to the county government so soon. !”
