Chapter 20 Bringing Graduates
"Brother Yu, what then?" Xiao Shen asked.

"Then?" Yu Qingyang waved to a worker, "Dig it out! Slow down!"

After the workers dug out the ring knife, Yu Qingyang gently removed the ring cover, "At this time, use a soil repair knife to cut off the remaining soil at both ends of the ring knife from the edge to the middle, and use a ruler to test until it is flattened.

Then take out the soil in the ring knife and put it on the scale to weigh!
Then use the formula, 4*(m1-m2)/πdh to find the wet density of the soil sample!
M1 refers to the weight of the ring knife with soil, and m2 refers to the weight of the empty ring knife.

Here we can omit it, because what we weigh now is directly the weight of the soil.

So just multiply 4 by the weight we weighed with the balance just now, and then divide by πdh! "Yu Qingyang spoke very patiently. As for whether they can listen to it or not, that's up to them.

When they are in school, the teacher will not care whether they learn or not.

When I arrived at the unit, I can’t say that there are no ones who can explain to them patiently like Yu Qingyang, but very few!
"Brother Yu, is this the end?" Xiao Jiang also asked.

Everyone was about the same age, and they were all young people. Seeing that Yu Qingyang was easy to talk to, Xiao Shen and Xiao Jiang didn't have so many worries and asked whatever they thought of.

"No, this is the first step, the next step is to measure the moisture content in the soil, and then calculate the dry density!

Use an alcohol stove to dry the soil sample just taken, and then weigh it!

The original soil weight - the dried soil weight, then divided by the dried soil weight, and then multiplied by 100% is the moisture content! "

"Brother Yu, how do you calculate the dry density?" Xiao Shen asked.

"The formula for calculating dry density is wet density divided by 1 + moisture content.

Compaction is dry density divided by maximum dry density times %.

The maximum dry density is the data obtained in the laboratory! "

Yu Qingyang was explaining, but did not listen to the movements of his hands.

Yu Qingyang hadn't done work like testing the degree of compaction for more than ten years in his last life.

Fortunately, I haven't forgotten it. I don't know if it's a rebirth benefit, but now I don't feel a little strange when I do it.

"Brother Yu, you are amazing!"

"What's so great? These are the most basic knowledge of dry technology!
You have them in your books, but you just didn’t pay attention! "

Yu Qingyang has brought many interns and graduates from technical colleges, and he knows that they are from technical colleges that started from junior high school.

You really don't learn much at school.

Few of the good students go to technical colleges, only those with bad grades.

The management of technical colleges is not much stricter than that of universities. How much knowledge do you expect such students to learn?

Most of them went to school on the construction site after graduation.

Only those who know how to learn by themselves and can adapt to the construction site can continue to work in this line.

Since the abolition of assignments in technical secondary schools and technical colleges this year, a large number of graduates have directly changed their careers to hang out in other industries.

"Xiao Yu, are you done?"

"This one is coming soon!
You two go over there with the ring knife and take another soil sample! "Yu Qingyang ordered the two of them to work casually.

After teaching for a long time, it's time to do some work.

"Xiao Yu, you have to take care of it, don't lie!"

"Brother Sun, I cheated on the degree of compaction, isn't that deceitful?

Don't worry, I won't do that! "Yu Qingyang responded with a smile.

Two people helped to take the soil samples, and Yu Qingyang did it very quickly, basically burning the soil with an alcohol stove wasted time.

After finishing everything, Yu Qingyang sorted out the test records, climbed up the embankment and handed it to Mr. Sun, "Brother Sun, look, the degree of compaction is all qualified! All are above 90.00% six! See if I can lay geotextiles, Do you have a template?"

"Okay, let's do it!" Sun Gong took a look, nodded, and murmured to the side, "Your little girlfriend has been waiting for you for a while!"

Yu Qingyang looked over at Sun Gong's words, and said with a wry smile: "Brother Sun, why are you making such a joke?
Don't talk nonsense about this, if it spreads, I don't care, she is a little girl, she has a bad reputation for her! "

Next to Lingling is a little boy who is about the same height as her, that is her younger brother.

Both siblings are thin, slender and tall, less than 1.7 meters tall.

Seeing Yu Qingyang looking at her, Lingling didn't dare to come over, but just stood there and smiled sweetly at Yu Qingyang.

Seeing Lingling's smile, Yu Qingyang's heart couldn't help but twitch.

At this time, it was after three o'clock in the afternoon, when the sun in the sky was poisonous.

These two fools actually stood in the sun and waited for themselves.

Then look at Uncle Tian inspecting the construction site accompanied by the chief of the high-tech section and supervisors Liu Gong and Wu Gong.

Stand in front of a small concrete mixing plant and study the necessity and importance of a small concrete mixing plant.

Seeing their efforts in research, Yu Qingyang didn't want to go and join in.

So she walked to Lingling and her younger brother, "Aren't you two hot? Why don't you go under the shed to hide from the sun?"

"It's okay, we're not afraid of the heat! Brother Yu, this is the loach we caught!" Lingling's face was flushed from the sun, and her younger brother's face was also flushed with anticipation in his eyes.

"So many?" Yu Qingyang asked in surprise.

There are two tin buckets under the feet of the siblings, both of which are filled with more than half of the buckets of loach.

The iron buckets used in rural areas can hold fifty catties of water. Yu Qingyang picked up the bucket and weighed it. A bucket contains about twenty or thirty catties of loach.

"My brother is really good at catching loaches! Most of these are caught by him!" Lingling had a cheerful smile on her face.

Yu Qingyang felt an inexplicable distress in his heart. These two fools probably didn't eat lunch in order to catch loaches.

"Have you eaten yet?"

"It's okay, we're not hungry, we'll go home and eat later!"

"Okay, this bucket is 600 catties, and the two buckets are 700 catties. I'll give you [-] yuan, and give me the other two buckets! Is it okay to give you a total of [-] yuan?"

"It's too much, Brother Yu, just give... four... 500 yuan!"

"Okay, stop earning, your brother Yu is not short of this money!"

"Thank you Brother Yu! I'll give you loach tomorrow! By the way, do you want eels?" Lingling took the money and said happily.

"Yes! Both!"

Yu Qingyang smiled wryly in his heart, and agreed with his mouth.

Looking at the siblings bouncing away.

Speaking of which, Lingling is only sixteen or seventeen years old, and she is also a child with a very innocent heart.

I only thought that catching loach could be sold for money, but I didn't think about it. There are only twenty or thirty people on my side, so how can I eat so much?

No matter how good loach is, you can't eat it every day!

Forget it, just treat it as atonement for the previous life!
The more I think about it, the more I feel that the things I did in my previous life were quite scumbags!
"Yangzi!" Uncle Tian walked over.

"Uncle Tian!"

"What's the matter with that girl?" Uncle Tian asked, looking at the back of Lingling who was going away.

"What's going on?" Yu Qingyang patted his head.

"You boy, don't pretend to be confused! Let me remind you, don't mess with me!" Uncle Tian reprimanded with staring eyes.

Uncle Tian has worked in the water conservancy industry all his life, and this kind of situation has been seen a lot.

There are quite a few people in the company. The daughter-in-law was brought back from the construction site. She messed around on the construction site and was detained by the family. She was not allowed to leave unless she got married.

It's not that Uncle Tian looks down on rural people, he is also a rural person.

Those who brought their wives back from the construction site were obviously not as good as others.

Moreover, after the novelty passed, living habits, cultural differences, and family conflicts continued.

It was for the good of Yu Qingyang that Chief Gao told Uncle Tian about this.

Worried that he is young, can't control it, and the trouble will end badly in the end.

Yu Qingyang rubbed his nose and promised with a smile: "I know, Mr. Tian, ​​I won't mess around!"

"It's good to know what's going on in your heart. Is there anything else you can do? I'll be back in a while! Do you want me to call your parents?"

"Uncle Tian, ​​why don't you leave now? Can you leave after dinner?"

"No, it's getting late, no matter how late it is, it's too dark to go!"

"Oh, by the way, Uncle Tian, ​​you take these two buckets of loach back! You can take one bucket, and I will trouble you to send another bucket back to my mother!"

"Hey, this loach is really good! Such a big loach is not easy to buy in Quanshui City!" Uncle Tian glanced into the tin bucket and said with a smile.

"Wait a minute!"

Yu Qingyang ran to find two pieces of plastic sheeting, wrapped the mouth of the tin bucket, and tied it with a rope, fearing that the loach would be suffocated, so he poked a few small holes in the plastic sheeting.

Then he carried it to Uncle Tian and loaded it into the car.

Uncle Tian left, and Gong Sun and the others also left.

Yu Qingyang arranged for workers to start laying geotextiles.

Between the concrete slope protection and the soil slope foundation, a layer of waterproof geotextile should be laid.

After the geotextile is laid, the formwork can be supported.

The tooth wall below and the criss-crossing ground beams in the middle are [-] centimeters thick, the underground grooves are buried [-] centimeters deep, and the concrete slab is [-] centimeters thick, so the final formed ground beams are [-] centimeters higher than the concrete slab.

The ten centimeters higher than this need to be shaped using a template.

"Brother Yu, what is that white one?" Xiao Shen leaned over to Yu Qingyang and asked in a low voice.

"That's a geotextile, it's for waterproofing! Although concrete is waterproof, it can't be 100% waterproof!
So add a layer of waterproof geotextile to waterproof! "

"Waterproof geotextiles? And non-waterproof geotextiles?" Xiao Jiang also asked.

"Yes, geotextiles are divided into waterproof geotextiles and permeable geotextiles.

They work differently!
Waterproof geotextiles, as the name suggests, are used for waterproofing!
Permeable geotextiles are used to prevent soil loss!
This means that water can pass through the geotextile and block the soil. "Yu Qingyang explained carefully.

"Brother Yu, what's the difference between waterproof geotextiles and permeable geotextiles? How to tell the difference?"

"Look, there is a waterproof membrane behind this waterproof geotextile! The waterproof geotextile does not have this waterproof membrane!"

"Stop it! You can't overlap like this!" Yu Qingyang suddenly shouted to stop.

"What's the matter, little boss? Is it right to overlap by [-] centimeters?" The worker looked at Yu Qingyang suspiciously.

Yu Qingyang was not in a hurry, and walked down the embankment slope to explain to them carefully, "It's my fault, I didn't make it clear. It's true that the overlap is [-] cm, but it can't be overlapped like this. The geotextile on the top should be used to press the geotextile below. .”

"Brother Yu, there's no difference? They're all overlapped by [-] centimeters, up and down, down and up, aren't they all the same?" Xiao Shen also followed Yu Qingyang down the slope, and asked suspiciously after hearing Yu Qingyang's words .
