"You, you know how to scare people."

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

"I'll take this little one back and give it to Brother Dongxu to taste."

Qin Huairu said with a smile, this time is really a bumper harvest, this stupid pillar really has a lot of family background.

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

"Pillar, you rest early, drink so much wine ..."

Qin Huairu was a little nervous, because the stupid pillar in front of him was some, crazy.

"Pillar, you rest early. Sister first."

Without waiting for her to continue, the stupid pillar leaned forward in two steps, stretched out his hand to hug Qin Huairu, and kissed him with one mouth.

Qin Huairu was startled and tried to dodge, but he couldn't dodge at all, so he could only avoid his face, protect his stomach with one hand, and stabilize the plate with the other, for fear of fighting.

But at this moment, I felt that the stupid pillar had already made inches.

Qin Huairu immediately stretched out his hand to push and pull, but he was afraid that the sound would be too loud for people to find out.

"Pillar, let go, let go."

"Huairu, Huairu, I"

I didn't know that the stupid pillar was drunk, and he didn't give up, the buttons on his chest were torn off, and his eyes were full of desire.

Qin Huairu saw it, how dare she continue?

She, the man is still there.

syllable

Silly Zhu was awakened by a slap, watching Qin Huairu quickly button up his cotton clothes, his eyes were red, and tears continued to flow silently.

"Qin... Sister..."

"I..."

Silly Zhu was a little flustered 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.

glanced at the stupid pillar, then picked up the plate, and walked to the cupboard to take out the one left for the stupid pillar.

"You, go to bed early."

With that, he opened the door and left.

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

"Hey, hey~"

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

This Sister Qin didn't refuse.

Ha ha

Lying on the bed with his head on his back, he fell asleep.

"Why didn't you come back sooner?"

Jia Zhang's squinted at Qin Huairu, every time Qin Huairu went to Silly Zhu to get a lunch box, she would close the door, and she didn't know what was going on inside.

With the worst thoughts, Jia Zhang's gaze at Qin Huairu became more and more unkind.

"Don't you see how many things are taken?"

Qin Huairu is also not polite, now she is not afraid of Jia Zhang's family, this old woman is bullying the soft and afraid of the hard, and the best thing is to play tricks, and she has no serious skills.

In this home, she found her place.

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

And in the night, they went to sleep.

Qin Huairu was lying on the bed, stroking the pinching marks on her chest, tears streaming from the corners of her eyes.

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

Ran Qiuye felt movement around her, opened her eyes, and then saw Yang Xiaotao's appearance, and the roots of her ears instantly turned red.

blame yourself for not being firm, why did you agree to this villain and do that shameful thing?

Yang Xiaotao saw his daughter-in-law's thoughts, reached out and hugged her, put her big hand on her lower abdomen, and stroked it slowly.

Ran Qiuye glanced at him, stretched out his hand and pinched his weakness, this will be to care about the child.

Yang Xiaotao laughed, and the two talked about it, and then got up.

When he came to the courtyard, Yang Xiaotao found the wooden stick left behind and practiced.

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

"Sharpen your guns!"

Yang Xiaotao listened to it, and his appearance was embarrassed, he really didn't practice well during this time.

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

After eating in the morning, Yang Xiaotao followed Yang Dazhuang and them to go around the fields, and the village had already planned the land before they came.

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

A few people walked around the field, and Yang Dazhuang said planning.

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

Today's arable land is far less fertile than in later generations, so water and manure are important resources, and solving these two problems can ensure food income.

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

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

Carrying water from the river and from the well will definitely ensure the growth needs of the corn.

Yang Xiaotao followed all the way, but did not see a well.

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

Yang Dazhuang was walking in front, and when he heard Yang Xiaotao's words, he pointed to the low-lying place in front of him, "It's right there." ”

Yang Xiaotao walked towards the well.

Several people saw each other and followed.

Coming to the well, Yang Xiaotao looked carefully.

The well is two meters in diameter, and the walls around it are stacked with stones, and the mouth of the well is paved with bluestone to facilitate access to water.

Seven or eight meters away from the wellhead, there is the surface of the water, and there are dead grass leaves floating on it.

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

"The surrounding land has also relied on it all these years."

Yang Dazhuang introduced, don't look at this well is not deep, but the speed of the spring is not slow, when the farm is busy, take turns to carry water, and there is no bottom.

Yang Xiaotao looked at the emptiness of the wellhead, and his memory quickly rose to his heart.

A gray-brown cylindrical iron bucket with an iron pipe pulled underneath, 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 a lever

Everything is so familiar.

That thing, it's called a pressurized well.

Before the crossing, there was a bite in Yang Xiaotao's grandmother's yard.

When I was a child, every time I went to my grandmother's house, I would grab water with my younger brother.

Grandma is washing vegetables and washing rice on the side, and the water that comes out in summer is even cooler, and when she is tired of going out to run, she lies directly on it and drinks it to her mouth.

At that time, looking at the novelty, I didn't understand how to pour so much water into it, how could the energy continue to come out?

Later, I went to school, learned about pressure, and learned why this happened, but every time I went, I could reap the joy.

Later, when my grandmother left, the brothers managed their own lives, and the pressurized water well became the best memory.

But the pressurized water well was still there.

Even when I built a house and used running water, I didn't touch it.

The old man said that it was the King of the Well Dragon and could not move.

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

Since it can be all the rage in more than ten years, it must be possible to advance it more than ten years in advance.

As for these four or nine cities, they will not be an exception.

I vaguely remember that I read 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 residents' lives, the excessive use of groundwater caused the groundwater level in Sijiu City to be lowered to less than 10 meters, and the pressurized water wells that had been used for decades could not press out water.

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

At such a high water level, it is possible to use a pressurized water well.

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

"You said the water wheel?" Yang Dazhuang thought for a while, "That thing has been used before, but the village thinks that the water is too slow, and it is better to use a flat pole to swing the water." ”

Yang Shishi beside him said and gestured on the side, "You have to shake this water wheel first, take the water and turn it up, and then pour it into the wooden bucket. Much faster. ”

"Xiao Tao, why are you asking this?"

"It's not practical, it's too delaying."

Yang Xiaotao shook his head, "I'm not talking about water rollers, I'm talking about if there is a person who sprays water on it himself, well, pressurized water wells,"

"Pressurized water wells? What is it? ”

"Will you get out of the water on your own? Tap water? ”

Yang Dazhuang and Yang Shishi were strange, Yang Xiaotao found a branch and drew a memory figure on the ground, and told a few people about the theory of knowledge for a long time, and several people still knew nine out of ten, and they didn't know anything.

In the end, Yang Xiaotao didn't say more, just wait for the real thing to be made and let a few people see it.

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

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

It is not easy to dig a well these days, not only need to find the right location, but also need to invest 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 over the years, and two more are used for domestic water in the village.

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

Yang Xiaotao kept this in his heart, and then continued to walk with everyone.

After returning to the village, Yang Xiaotao told Mrs. Yang about the pressurized water well.

Mrs. Yang didn't understand, but he knew Yang Xiaotao's ability, since he said that he could do it, then he could.

Let Yang Xiaotao rest assured to do it boldly.

After eating at noon, he went back to Sijiu City with Ran Qiuye.

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

As for the original pressure cooker, he put it aside and talked 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 think it at first, but after painting, he looked at the formed design drawing, and realized that this design painting was eight or nine points similar to the pressurized water well in his grandmother's house in his memory.

Different from the previous design of the heating stove, this time, Yang Xiaotao felt very smooth, just like doing a math problem, which he used to think hard about and meditate to do in a stupid way.

And standing, can be made with two or three ideas.

Perhaps, this is the change that comes with becoming an engineer.

Yang Xiaotao was in a happy mood, and Ran Qiuye on the side waited for Yang Xiaotao to rest before he stepped forward, looking at the clearly marked pressurized water well, his face was full of doubts.

"That's it, you can get your own water?"

Ran Qiuye didn't understand that in her education process, she had very little contact with physical science, even mathematics, and she also learned some after her father.

As for the basics, what is taught in schools is basic.

"Have you ever heard a phrase?"

"What?"

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

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

"No, no. How dare I say it. ”

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

Sure enough, the pregnant woman is just too sensitive and feels that everything is aimed at her.

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

"Atmospheric pressure, I'd love 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 didn't give her any lessons.

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

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

Ran Qiuye talked about his father, and his spirit came up again.

Yang Xiaotao is also interested in this father-in-law who has not met, after all, the other party is a 'top student' who studied abroad, and he doesn't talk about this world, even before he crossed over, he never went out of the province.

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

In addition, the materials of the pressurized water wells are also considered.

In line with the principle of saving money, the wellbore of the pressurized water well is made of cast iron, and the connected pipes can be made of waterworks.

As for the check valve of the wellbore, it is simpler, find two leather pads, and with a little processing, one piston and one valve can be solved, which is difficult from time to time.

As for the tightness, it is completely dependent on the water itself to ensure it, it is 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 with wood, saving iron.

Busy until midnight, everything was considered, Yang Xiaotao put away the drawings and planned to go to the rolling mill on Monday to try.
