Scholars in the courtyard

"You know how to scare people."

Qin Huairu smiled, put away the plates, and put a large plate in the cupboard, "This is for you, you can eat it tomorrow."

"I'll take this small one back and give it to Brother Dongxu to try."

Qin Huairu said with a smile, "It's been a great harvest this time. This silly Zhu has a lot of money."

Silly Zhu breathed out a breath of alcohol, looked at Qin Huairu smiling at him, and slammed the door shut.

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

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

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

Before she could continue, Shazhu came closer in two steps, stretched out his hand to hug Qin Huairu, and kissed her with his mouth open.

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

But at this moment, I felt that Shazhu had gone too far.

Qin Huairu immediately stretched out her hand to push and pull, but was afraid that the sound would be too loud and others would find out.

"Zhuzi, let go, let go."

"Huairu, Huairu, me"

Unexpectedly, Silly Zhu was so drunk that he refused to give up. The buttons on his chest were torn open, and his eyes were full of desire.

Qin Huairu saw it, how could he dare to continue?

She, the man is still there.

Snapped

Silly Zhu was woken up by a slap in the face and watched Qin Huairu fasten the buttons of his cotton coat, his eyes were red and tears kept flowing down silently.

"Sister Qin..."

"I…"

Silly Zhu was a little panicked and didn't know what to say.

Qin Huairu stretched out her hand to wipe away her tears, and her face quickly returned to calm.

He glanced at Silly Zhu, then picked up the plate, walked to the cupboard and took out what was left for Silly Zhu.

"sleep early."

Saying that, he opened the door and left.

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

"Hey, hey~"

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

This Sister Qin did not refuse.

Ha ha

He lay on the bed with his head up and fell asleep.

"Why didn't you come back earlier?"

Mrs. Jia Zhang looked sideways at Qin Huairu. Every time Qin Huairu went to Si Zhu's place to get the lunch box, she would close the door. She didn't know what was going on inside.

Thinking about the worst, Jia Zhang looked at Qin Huairu with increasingly unkind eyes.

"Didn't you see so many things?"

Qin Huairu is not polite either. Now she is not afraid of Jia Zhang. This old woman bullies the weak and fears the strong. What she is best at is playing tricks and fooling around. She has no serious ability at all.

In this family, she found her place.

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

At night, everyone went to sleep.

Qin Huairu lay on the bed, stroking the pinch marks on her chest, tears streaming from the corners of her eyes.

The next day, Yang Xiaotao got up from the gentle village, looked at the sleeping Ran Qiuye, and thought of the absurdity last night, feeling proud.

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

I blame myself for not being firm, why did I agree to this bad guy and do that shameful thing?

Yang Xiaotao saw his wife's thoughts, reached out and hugged her regardless, put his big hand on her belly, and caressed her slowly.

Ran Qiuye rolled her eyes at him and stretched out her hand to pinch the weak spot. She was now caring about the child.

Yang Xiaotao laughed with him, and the two talked for a while before getting up.

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

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

"Sharp your guns before the battle!"

Yang Xiaotao looked embarrassed after hearing this. He really hadn't practiced well during this period.

After practicing for a while and sweating, Yang Xiaotao returned to the room and prepared to eat.

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

Stepping on the frozen ground, the dirt that would normally be kicked away is now as hard as stone.

A few people were walking around in the field, and Yang Dazhuang was talking about plans.

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

Today's cultivated land is far less fertilized than in later generations, so water and manure are important resources. Solving these two items can ensure the generation of food income.

In this regard, when planning the corn planting area, Yang Dazhuang and others also planned 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 definitely ensure the growth needs of corn.

Yang Xiaotao followed along, but didn't see a well.

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

Yang Dazhuang was walking in front. When he heard Yang Xiaotao's words, he pointed to the low-lying area ahead, "It's right there."

Yang Xiaotao walked towards the well.

Several people saw him and followed him.

Arriving at the well, Yang Xiaotao looked carefully.

The well is two meters in diameter. The surrounding walls are piled up with stones, and the wellhead is paved with bluestone for easy access to water.

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

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

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

Yang Dazhuang introduced that although this well is not deep, the spring water is not slow. When the farmers are busy, they take turns fetching water without seeing the bottom of the water.

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

A gray-brown cylindrical iron bucket, with an iron pipe pulled from the bottom, an opening at the top, an iron pipe inserted in the middle and upper position, an iron rod bulging high above, and an iron root using the principle of leverage.

Everything is so familiar.

That thing is called a pressure well.

Before time travel, there was one in the courtyard of Yang Xiaotao's grandmother's house.

When I was a child, every time I went to my grandma's house, I would fight with my brother to press water.

Grandma was washing vegetables and washing rice. In the summer, the water she pumped out was even cooler. When she was tired from running around, she would just lie down on it and drink from her mouth.

At that time, I looked at it as a novelty and wondered how the energy could come out continuously after pouring so little water into it.

Later, when I went to school, I learned about pressure and why it happened, but every time I went there, I gained joy.

Later, when my grandma passed away and the brothers managed their own lives, the pressurized water well became the best memory.

But the pressurized water well is still there.

Even when a house was built and tap water was used, it was not touched.

The old man said that it was the Jing Dragon King and could not be moved.

Yang Xiaotao woke up from his memories and rubbed his eyes.

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

As for these four or nine cities, there will be no exception.

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

At that time, for the sake of industrial development and residential life, the excessive use of groundwater caused the groundwater level in Sijiucheng to drop to less than ten meters. Even the pressure wells that had been used for decades could not pump out water.

Yang Xiaotao nodded after hearing this. Sijiu City has not yet reached the point where it is difficult to use water, and the surrounding water resources are still abundant.

With such a water level, pressurized water wells can be used.

"Uncle Da Zhuang, is there no one drawing water from this well?"

"You mean that water puller?" Yang Dazhuang thought for a while, "That thing has been used before, but the village thought it was too slow to get water. It would be better to use a pole to get the water faster."

Yang Shitou beside him said and gestured to the side, "You have to shake this water puller first, get the water, turn it up, and then pour it into the wooden bucket. At this time, hook the iron bucket with the pole and swing it up. Come up. It's much faster."

"Xiao Tao, why do you ask this?"

"This thing is impractical and delays things too much."

Yang Xiaotao shook his head, "I'm not talking about the water puller, I'm talking about, if there is a water puller that sprays water on its own, well, it's a pressurized water well."

"Press well? What is it?"

"Can you still get water out on your own? Is there tap water?"

Yang Dazhuang and Yang Shitou were surprised. Yang Xiaotao found a branch and drew memory patterns on the ground. He also lectured on knowledge and theory to a few people for a long time, but they still understood nine out of ten and knew nothing.

In the end, Yang Xiaotao said no more, just wait until the actual object is made and let a few people see it.

Then several people walked around again, and Yang Xiaotao paid more attention to the location of the well.

He also realized that in order to have a pressure well, there must also be a water well.

It is not easy to dig a well these days. It not only requires finding the right location, but also investing a lot of manpower and material resources. These two items alone deter many villages.

Yangjiazhuang is close to the river and has richer groundwater, so there are relatively more wells in the village. But even so, there have only been eight wells over the years, and two of them are used for domestic water in the village.

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

Yang Xiaotao kept this in mind, and then continued walking with the others.

After returning to the village, Yang Xiaotao talked to Mr. Yang about the pressure well.

Mr. Yang doesn't understand either, but he knows Yang Xiaotao's ability. If he says he can do it, then he can.

Let Yang Xiaotao do it boldly.

After lunch, Ran Qiuye and Ran Qiuye returned to Sijiu City.

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

As for the original pressure cooker, he put it aside and would talk about it when he had time.

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

Yang Xiaotao didn't feel it at first, but after he finished the painting and looked at the completed design, he realized that this design painting was eighty-nine times similar to the pressure well in his grandma's house in his memory.

Different from the previous design of the heating furnace, this time, Yang Xiaotao felt that it was very smooth, just like doing a math problem that he had worked hard to solve in a stupid way before.

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. Ran Qiuye, who was on the side, waited for Yang Xiaotao to rest before approaching him. He looked at the clearly marked pressure wells with doubts on his face.

"Can this thing fetch water by itself?"

Ran Qiuye didn't understand. During her education, she had very little exposure to physical sciences. Even mathematics, she learned some from her father.

As for what is taught in school, they are all basic knowledge.

"Did you hear a word?"

"What words?"

"Learn mathematics, physics and chemistry well, and you won't be afraid of traveling all over the world."

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

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

Yang Xiaotao reached out and hugged Ran Qiuye, why did he forget about his father-in-law? This way he avoided a 'war'.

Sure enough, a pregnant woman is too sensitive and feels like everything is directed at her.

Then Yang Xiaotao introduced to Ran Qiuye what atmospheric pressure is and the working principle of water pressure wells.

"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 her father was at home, he had taught her a lot.

"I remember that my father wrote a lot of this knowledge at that time, stapled a separate notebook, and kept it at home."

"I'll go home and look for it tomorrow. Maybe it's still useful."

Ran Qiuye became energetic again when he talked about his father.

Yang Xiaotao also became interested in this father-in-law whom he had never met before. After all, he was a 'top student' studying abroad, and he didn't know much about this world. He had never been out of the province before traveling.

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

And the materials of the pressurized water well are also considered.

In line with the principle of saving what can be saved, the shaft of the pressurized water well is made of cast iron. As for the connecting pipes, pipes from the water plant can be used. If this fails, one can be made from the steel rolling mill.

As for the one-way valve of the wellbore, it is even simpler. Just find two leather cushions and do a little processing. One piston and one valve can be solved, which is sometimes difficult.

As for the sealing, it can be ensured by the water itself. It is nothing more than shaking it twice from time to time. Even a child can complete it.

Finally, press the handle. This thing can be replaced by wood to save iron.

After being busy until midnight, Yang Xiaotao put away the drawings after considering everything, and planned to go to the steel rolling mill on Monday to try it out.
