Scholars in the courtyard.

Chapter 408 Pressure Wells

"You know how to scare people."

Qin Huairu smiled, put away the plate, and then put a large plate in the cupboard, "This is for you, I'll eat it tomorrow."

"This small one is left, I'll take it back and give it to Brother Dongxu to taste."

Qin Huairu said with a smile, this time is really a bumper harvest, this silly Zhu has a lot of money.

Silly Zhu let out a mouthful of alcohol, watched Qin Huairu smile at him, and slammed the door shut.

"Zhuzi, go to bed early, drink so much wine..."

Qin Huairu was a little nervous, because the silly Zhu in front of her was a little crazy.

"Zhuzi, go to bed early. Sister first."

Before she could continue, Sha Zhu leaned forward in two steps, stretched out his arms to hug Qin Huairu, and kissed her with the first opening.

Qin Huairu was startled, and tried to avoid it, but she couldn't dodge it at all, she could only avoid her face, protecting her stomach with one hand, and holding the plate with the other, for fear of being hit.

But for a while, I felt that Sha Zhu had already pushed his limits.

Qin Huairu immediately reached out to push and pull, but was afraid that the sound would be too loud and people would find out.

"Pillar, let go, let go."

"Huairu, Huairu, me"

Unexpectedly, Shazhu's wine was strong, and he refused to let go, the buttons on his chest were all torn off, and his eyes were full of desire.

Seeing Qin Huairu, how dare he continue?
She, the man is still there.

Snapped

Silly Zhu was awakened by a slap across the face, watching Qin Huairu quickly button up the cotton coat, his eyes were red, and tears kept streaming down silently.

"Sister Qin..."

"I…"

Silly Zhu was a little flustered, not knowing what to say.

Qin Huairu wiped away her tears with her hand, and her face quickly returned to calm.

He glanced at Silly Zhu, then picked up the plate, went to the cupboard and took out the ones reserved for Silly Zhu.

"sleep early."

Then he opened the door and left.

Silly Zhu watched Qin Huairu walk away, and the crotch finally disappeared.

"Hey, hey~"

Silly laughter continued, the tension just now had dissipated, and there was even more hope in my heart.

Sister Qin didn't refuse.

Haha
He lay on his back on the bed and fell asleep.

"Why didn't you come back earlier?"

Jia Zhangshi squinted at Qin Huairu, every time Qin Huairu went to get a lunch box from Shazhu's, she would close the door, and she didn't know what happened inside.

Thinking about it with the worst intentions, Jia Zhang looked at Qin Huairu more and more unkindly.

"Didn't you see so many things?"

Qin Huairu is also not polite, now she is not afraid of Jia Zhang, this old woman is bullying and afraid of tough, the best at playing tricks, she has no serious ability.

In this home, she found her place.

Jia Zhang snorted coldly, but took the basin, looked at the food inside, and smiled triumphantly.

At night, everyone fell asleep.

Qin Huairu lay on the bed, stroking the pinch mark on her chest, tears streaming down her eyes.

The next day, Yang Xiaotao got up from the gentle village, looked at the sleeping Ran Qiuye, remembered the absurdity of last night, and felt triumphant.

Ran Qiuye felt movement around him, opened his eyes, and saw Yang Xiaotao's appearance, his ears turned red instantly.

Blame myself for not being firm, why did I agree to this scoundrel and do such a shameful thing?

Yang Xiaotao saw what his daughter-in-law was thinking, so he reached out and hugged her regardless, put his big hand on his lower abdomen, and stroked it slowly.

Ran Qiuye rolled his eyes at him, stretched out his hands to pinch his weak spot, he really cared about the child.

Yang Xiaotao laughed along with him, the two had a conversation, and then got up.

When he came to the yard, Yang Xiaotao found out the wooden sticks left behind and practiced.

After a while, Grandpa Yang came in from the outside, stood beside Yang Xiaotao, and watched for a while.

"Grind your gun before the battle!"

When Yang Xiaotao heard this, he looked embarrassed. He really didn't practice well during this time.

After practicing for a while and sweating, Yang Xiaotao went back to the house and prepared to eat.

After dinner in the morning, Yang Xiaotao followed Yang Dazhuang and the others to go around the fields. Before coming, the village had already planned the land.

Stepping on the frozen ground, the dirt that can usually be kicked away is now as hard as a rock.

Several people walked around in the field, and Yang Dazhuang was talking about the plan.

Most of the land is fertile land near the river, which is also the main planting area of ​​the farm.

Today's arable land is far from having as much fertilizer as later generations, so water and manure are important resources. If these two items are solved, we can ensure the income generation of food.

In this regard, when planning the corn planting area, Yang Dazhuang and the others also carried out around the river.

However, this will inevitably affect the cultivated area. The opinion discussed by Yang Dazhuang and others is to carry water for irrigation.

Carrying water from rivers and wells will surely ensure the growth needs of corn.

Yang Xiaotao followed him all the way, but he didn't see a well.

"Uncle Zhuang, here, where is the nearest well?"

Yang Dazhuang was walking ahead, when he heard Yang Xiaotao's words, he pointed to the low-lying place ahead, "It's right there."

Yang Xiaotao walked towards the well.

Several people saw and followed together.

When he came to the well, Yang Xiaotao looked it over carefully.

The well is two meters in diameter, and the surrounding walls are piled up with stones, and the mouth of the well is even paved with blue stones to facilitate water intake.

Seven or eight meters away from the wellhead is the water surface, with dead grass leaves floating on it.

"This is the well that the work team came down to dig during the land reform. It took a lot of effort at the time, but after the well was dug, no one was missing."

"The surrounding land has also relied on it over the years."

Yang Dazhuang introduced that although the well is not deep, the speed of the spring water is not slow. When the farming is busy, the water is carried in turns, and the bottom of the water is not visible.

Yang Xiaotao looked at the empty top of the well, and the memory quickly came to his mind.

A gray-brown cylindrical iron barrel, with an iron pipe pulled underneath, an iron pipe inserted in the upper middle, an iron rod bulging high above, and an iron root using the principle of leverage
Everything is so familiar.

That thing is called a pressurized well.

Before crossing over, there was one in the yard of Yang Xiaotao's grandma.

When I was young, every time I went to my grandma's house, I would compete with my younger brother to press the water.

Grandma was washing vegetables and rice. In summer, the water was even cooler. When I was tired from running, I just lay down on it and drank it.

At that time, looking at the novelty, I didn't understand how to pour so much water into it, how could the energy come out continuously?
Later, I went to school, learned about the pressure, and knew why it happened, but every time I went, I could reap joy.

Later, grandma left, and the brothers managed their own lives, and the pressurized well became the best memory.

But the pressurized well is still there.

Even when building a house and using tap water, it has not been touched.

The old man said that it was Jinglong King and he couldn't move.

Yang Xiaotao woke up from the memory, then rubbed his eyes.

Since it can become popular more than ten years later, it must be possible ten years in advance.

As for the four or nine cities, there is no exception.

I vaguely remember reading a report about water wells in my previous life, which mentioned the changes of water wells in Sijiu City.

At that time, for the sake of industrial development and residents' daily life, groundwater was used excessively, which caused the groundwater level in Sijiu City to drop to below ten meters.

Yang Xiaotao listened and nodded. Now Sijiu City has not reached the level of water shortage, and the surrounding water resources are still abundant.

With such a water level, it is completely possible to use a pressurized well.

"Uncle Zhuang, is there no one to draw water from this well?"

"You mean the water pulley?" Yang Dazhuang thought for a while, "That thing has been used before, but the village thinks it's too slow to fetch water, so it's better to use a pole to get water quickly."

Yang Shitou beside him said and gestured beside him, "You have to shake the water wheel first, get the water and turn it up, and then pour it into the wooden bucket. Come up. Much sooner."

"Xiaotao, why are you asking this?"

"This thing is not practical, it is too late."

Yang Xiaotao shook his head, "I'm not talking about the water pulley, I mean, if there is someone who sprays water up by himself, um, pressurize the well,"

"Press well? What?"

"Will it produce water by itself? Tap water?"

Yang Dazhuang and Yang Shitou were surprised. Yang Xiaotao found a tree branch and drew a picture of memory on the ground, and then explained the theory of knowledge to a few people for a long time.

In the end, Yang Xiaotao didn't say any more, and just waited until the real thing was made and let a few people see it.

Then the few people stopped and went, and Yang Xiaotao paid more attention to the location of the well.

He also realized that if there is a pressurized well, there must be a well.

Digging a well these days is not easy. Not only does it need to find the right location, but it also requires a lot of manpower and material resources.These two items alone have discouraged many villages.

Yangjiazhuang is close to the river, and the groundwater is more abundant, so there are relatively many wells in the village, but even so, there are only eight wells in these years, and two of them are used for domestic water in the village.

It can be seen how difficult it is to drill a well.

Yang Xiaotao kept this matter in mind, and then followed the crowd to continue walking.

After returning to the village, Yang Xiaotao told Mr. Yang about pressing the well.

Mr. Yang didn't understand either, but he knew what Yang Xiaotao was capable of. Since he said he could do it, he could.

Let Yang Xiaotao do it boldly.

After lunch, I went back to Sijiu City with Ran Qiuye.

After returning to the courtyard, Yang Xiaotao began to recall the structure of the pressurized well.

As for the original pressure cooker, he put it aside until he had time.

Following his memory, Yang Xiaotao kept writing and drawing on the table, and quickly drew the general outline.

Yang Xiaotao didn't feel it at first, but after looking at the finished design drawing, he realized that the design and painting this time were [-]-[-]% similar to the pressurized well in his grandma's house in his memory.

Different from the previous design of the heating stove, this time, Yang Xiaotao felt that it went smoothly, just like doing a math problem, which he used to think hard and use a clumsy way to solve.

As for standing, you can use two or three ideas to make it.

Perhaps this is the change brought about by becoming an engineer.

Yang Xiaotao was in a happy mood, and Ran Qiuye waited for Yang Xiaotao to take a break before he stepped forward. Seeing the clear marking of the pressurized well, his face was full of doubts.

"Just this thing, can it fetch water by itself?"

Ran Qiuye didn't understand. During her education, she had little contact with physical science. Even mathematics, she learned a little after her father.

As for the basic knowledge taught in the school.

"Have you heard a word?"

"What?"

"If you learn mathematics, physics and chemistry well, you won't be afraid to travel all over the world."

Ran Qiuye was stunned for a moment, and immediately came to his senses, "You mean I'm not good at mathematics and physics."

"No, no. How dare I say that."

Yang Xiaotao stretched out his arms to hug Ran Qiuye, why did he forget about the father-in-law, and thus avoided a 'war'.

Sure enough, a pregnant woman is too sensitive, feeling that everything is aimed at her.

Then Yang Xiaotao introduced to Ran Qiuye what atmospheric pressure is and how the pressurized well works.

"Atmospheric pressure, I really want to hear my father talk about it. Oh, it's so simple, I thought it was very profound."

Ran Qiuye suddenly realized that when his father was at home, he taught her a lot.

"I remember that my father wrote a lot of knowledge like this at that time, nailed up a separate notebook, and put it at home."

"Hurry up and I'll go home and look for it, maybe it's still useful."

When Ran Qiuye talked about his father, his spirits recovered.

Yang Xiaotao also became interested in this father-in-law whom he hadn't met, after all, he was a "high-achieving student" studying abroad, and he didn't talk about this world anymore, even if he had never been out of the province before crossing.

The two talked again, Yang Xiaotao put Ran Qiuye to sleep, and continued to modify the pressurized well.

Moreover, the material of the pressurized well is also considered.

In line with the principle of saving what can be saved, the wellbore of the pressurized well is made of cast iron. As for the connecting pipes, the pipes from the waterworks can be used.

As for the one-way valve of the wellbore, it is simpler. Find two leather cushions, and with a little processing, one piston and one valve can solve it, which is often difficult.

As for the tightness, it can be guaranteed by the water itself, nothing more than shaking it twice from time to time, even a child can do it.

Finally press the handle, this thing can be replaced by wood, saving iron.

After working until midnight, Yang Xiaotao took everything into consideration, and then put away the drawings, planning to go to the rolling mill to try it on Monday.
