The Zheng family's timber shop is not only the only one in Fengshan, but also the oldest timber shop in Fengshan, and some of the timber bought by Zhao Jinyu was purchased from here.

Chen Da Niu is a bit real, the boss tells him to do whatever he wants, working for the Zheng family from a small apprentice to the only master now, skilled in craftsmanship, decades of conscientious work has not made any major mistakes, The signboard can also be taken in Fengshan, Fengshan because he is in charge, no one has stolen his limelight from the carpenter.

He is not worried about the people outside, but he is afraid of the people of the Zheng family, not that the Zheng family treats his buddies badly, but when he gets older, he will want to change some young people to the position.

Zheng Ruoying explained his affairs, he took all his apprentices to fight with eighteen martial arts overnight, and he was all done in one night's effort. He didn't know that He Baozheng, the little person who collected sawdust, still knew the eldest lady of the Zheng family, but now he didn't want to offend the people around the eldest lady, so he finished the waterwheel frame ordered by Zheng Ruoying, and asked the apprentice to sweep the sawdust on the ground clean, receive it in the bag, and prepare to let He Baozheng take it back next time he comes.

Liang Chuan also thought that these carpenters would put down the score, grinding foreign workers, because in ancient times the status of carpentry is not low, not generally not worrying about no food, only others are polite to them, others generally do not offend them, the ancients are a little more superstitious, carpenters in the work of a little hands and feet, according to Feng Shui, will affect luck.

He still came to Fengshan in He Baozheng's ox cart, but he didn't expect that Chen Daniu had already prepared all the things he had designed and required. The two of them didn't give money, they said a few polite words, pulled two wooden rings and left, and when they left, Chen Daniu also asked He Baozheng to take away a lot of sawdust.

These sawdust can make a lot of mosquito coils.

Liang Chuan bought a lot of hemp rope along the way, and he may use the bamboo tubes and bamboo poles on the fixed waterwheel.

I don't know how Zheng Ruoying would feel if she knew that her family's wood chips were processed by herself and then sold in the store.

He Baozheng instructed all the village girls to go up the mountain today, and today they should cut down the bamboo and carry it to the edge of Nanxi, ready to make a waterwheel for Liangchuan. They don't know what to do with the waterwheel, but what Liang Chuan said they are like gods, since yesterday Liang Chuan is their food and clothing parents, yesterday to take a few hundred dollars home, the men in the family are not surprised, can not pull down, otherwise they will also come to learn to make bamboo weaving.

Two women carried a bamboo, and more than 30 village girls carried more than a dozen of them, neatly stacked by the river, waiting for Liang Chuan. Liang Chuan picked up a few smoother and straighter bamboos, cut them with a brush, and the hole that could be inserted into the axle would not come out, and then cut out twenty bamboo tubes, and let them all take the rest back to make bamboo weaving.

Zheng Ruoying summoned a large number of farmers to wait by the river, these farmers have strong muscles, but they have no spirit, at first glance, they are the typical type of not urging and moving, urging slow movement, they are all holding pickaxes, hoes and other guys in their hands, all of them are fresh faces.

Liang Chuan instructed them to dig a pit in the river first and drive two wooden stakes into the water. These peasants looked a little wooden, but they were quite clever in doing things, they first went to the place where they were going to dig the pit and dug the earth and stones to surround it, scooped up the water in it, and then began to dig the river pit so that the water would not go in, and it was good to dig the pit.

Liang Chuan was also worried that it would be difficult to dig a pit in this environment without machinery and equipment, but he didn't expect that there would be such a method.

The other side of the stake is on the bank of the river, which is better to dig, but slowly some of the river water will seep out, and they divide the work, and one person is responsible for clearing the water in the pit, scooping it up with a wooden barrel and pouring it out.

"Lao He, take a hand, let's assemble this waterwheel." He Baozheng watched everyone work in full swing, standing aside stupidly, worrying that he couldn't help, which seemed a little redundant.

Liang Chuan asked He to carry the axle and plug the long bamboo poles one by one, a bit like the spokes of a bicycle. The other end of these poles is also tied to the log ring, so the hole in the log axle is inserted, and there is no need to use other tenons.

Two wooden hoops are arranged symmetrically side by side, like a wheel basket, and two people each hold hemp rope to tie the bamboo pole and the wooden circle together. Although the hemp rope is tied together, the force area also becomes larger, and under the action of the thrust of the water flow, the waterwheel rotates slowly and urgently.

The role of the bamboo tube is also the role of the impeller, the kinetic energy of the water brings enough impulse, although the wheels of the waterwheel are huge and bulky, but once started, the thrust behind needs to bear the mass of the entire water wheel. This is like the car costs fuel when it is just started, but it will save fuel when it is started.

The frictional resistance of the wheel axle of the waterwheel is large, because the iron bearing with good performance cannot be found in this era, but it is not used, and the steel ball bearing rotates too smoothly, just imagine the waterwheel spinning at high speed like a wheel in the river, and it will fall apart after a while.

A few farmers drove piles at an astonishing rate, and in a few moments they dug two large holes in the riverbank. They stuck two hardwood stakes into the pit and stuffed them with a few pieces of bluestone, which stood firmly on the riverbank. Then take some soil and stone mixture and pour it into the pile pit, and move a large number of stones to the top of the exposed water, and the hard pile is basically laid.

After the hard pile is drilled, the waterway is dredged. The water here in the shallows is less than a foot deep, and when the waterwheel is put down, let alone turning, it can't even submerge the bamboo tube. Several people dug a long culvert in the riverbed in the direction of the rotation of the waterwheel, more than three feet deep, so that the waterwheel could have enough draft.

In order to prevent the hard pile erected in the river from collapsing after being washed by the river for a long time, Liang Chuan wondered if he could get a little cement and pour it up, but he was not very familiar with the formula for making cement. A large amount of sand and pebbles were dug out of the riverbed, and these were simply piled up on the riverbed, and then some stones were dug on the land to make the shape of a water-dividing fish mouth, the river channel has an illusion of being divided into two here, and the water flow either flows downstream from the fish mouth or flows into the culvert, which does not invade each other, a bit like the principle of water division in Dujiangyan, but this is a hard pile to protect and support the waterwheel, and it is estimated that it will be finished when it encounters floods.

After hanging the bamboo tube, the waterwheel has been basically assembled, and the outer round of the log ring and the middle log axle are made of bamboo poles as spokes, and it looks like a huge wheel from a distance. Ma Dan looks like a big toy.

The same is true for farmers digging culverts, first blocking the mouth of the fish entering the water, and it is much easier to dig without water, and the riverbed has been soaked in the river water for a long time, and it has long been very soft, and a large piece of mud can be dug up with a hammer. The culvert doesn't have to be dug too wide, just a few more than the width between the two rings.

More than a dozen farmers flew up and down with hoes and axes, and the mud they dug up was piled up on the edge of the hard piles in the river, so that they no longer had to move to the shore, which made their speed and efficiency skyrocket.

Liang Chuan asked Ma Dan where the fish baskets were hanging, but he didn't see them, and Ma Dan pointed to the location of the tree on the bank of the river where he fell last time, and there were several ropes tied to the tree.

"You've been busy all day, what are you doing here? Is it possible to catch more fish? Ma Dan asked Liang Chuandao, he had never seen such a thing in the north.

"This is a waterwheel, you can't catch fish, but in the future, your father and they don't have to run to the river to fetch water, the river can run to the shore by itself!" Liang Chuan said.

In the past two days, Fan Dianyuan and Lao Ma have also gone to the river to get water, and they saw from a distance that many people on the bank were busy with something, but they had to water the ground, so they didn't have time to come over to say hello.

"How can the river run to the shore on its own? Brother Zhang, are you going to use spells again? ”

He Baozheng doesn't like children to talk nonsense, children's words can't be unscrupulous, and when they grow up, they will be open-mouthed. He glared at the child from the outsider, and said in a heavy tone, "What spell?" What are the children's nonsense? ”

Ma Dan didn't know anything He Baozheng, and said: "Last time I fell into the river and drowned, several other children said that I didn't breathe, my face was blue, Brother Zhang made it on me for a long time, and he saved me again, what do you say this is not a spell?" ”

Ma Dan said eloquently, He Baozheng didn't look like he was lying, and looked at Liang Chuan again, Liang Chuan said helplessly: "Didn't you tell others not to tell me, why did you mention this again?" ”

Liang Chuan's words were equivalent to admitting the fact that he knew spells, He Baozheng's eyes were a little drifting when he looked at him, and he muttered in his mouth, unable to speak, "San Lang. Is this kid telling the truth? ”

"It's not exactly, where do I know any spells, it's that the child chokes on water, and the person comes back to life when he gets the water out of his stomach... Liang Chuan knew that it was in vain, where did they understand the truth of artificial respiration and cardiopulmonary resuscitation.

"The village. . . People say that you come across it when you go into the mountains. Mountain god. He Baozheng chattered.

Liang Chuan smiled bitterly: "He Baozheng, don't eat at my house after you listen to their nonsense, have you seen that I have eaten one less meal!" If I had fought the tiger so hard last time, I would have died by pointing at the tiger with my hand! You've lived a long time and still listen to their nonsense? ”

When the two chatted, the farmers had already dug the culvert, and Liang Chuan calculated the depth of the culvert and the draft of the waterwheel, which was already enough to meet the draft of the waterwheel. Dozens of people worked together to put the big guy on a pile on the riverbed.

Whether this waterwheel can succeed and tie up the irrigation of hundreds of acres of land along the north shore. If it succeeds, next time everyone can imitate, manpower can also be liberated from the river, even if the weather is hot in the future, there is no rain for a few years, as long as there is water in the South Creek, the north bank will not have to worry about watering the ground, and even the land on the north bank will be transformed into paddy fields because of the waterwheel! This is different, there are a few acres of paddy fields at home, who still goes outside to work, just starve to death!

Everyone stared nervously at the waterwheel.

"Break the water!" Liang Chuan said.

"San Lang, do you want to wait for the eldest lady of the Zheng family?" He Baozheng asked.

"Don't wait, what are you waiting for her?" Liang Chuan's tone was firm.

With Liang Chuan's order, the two farmers broke through the mud and stones blocking the water at the mouth of the fish, and the dug water rushed into the culvert, and the water flow soon flooded the culvert, and the water flowing into the water outlet became more rapid because the waterway narrowed. Gradually, the waterwheel, which had been motionless, squeaked and began to move slowly!

"It's moving!" He Baozheng burst out with an exclamation, I didn't expect this thing to really move! The other peasants who helped were also amazed, but they didn't understand why.

The momentum gained by the bamboo tube caused the waterwheel to spin slowly, faster and faster, and finally stabilized, turning in the riverbed without hurry, squeaking from time to time.

The bamboo tube that was originally immersed in water was lifted away from the water surface, because the bamboo tube has a certain angle of inclination, and when the bamboo tube mouth is higher than the bottom of the tube at a low place, the bamboo tube will hold water and fill it with a bamboo tube. As the waterwheel rotates, after turning to a high place, the position of the cylinder mouth will be lower than the bottom of the cylinder, and the water in the bamboo tube will flow out with the trend, and there will be an arc like pouring water.

It worked!

By the side of the waterwheel, the master will install a water tank to divert the water poured from the water pipe, and the water of the South Stream can be diverted from the stream to the north bank. Although each bamboo tube does not pour out much water each time, but this waterwheel keeps diverting water day and night, without manpower and animal power, accumulating a lot, the water flows continuously, hundreds of acres of land, it is not a problem, and even have to worry that after the water flow is enough, the sink must be released in time, otherwise the water will overflow.
