"Xiao Jiang, pull the ruler to find a place four meters away, hold it down and don't move!
Xiaoji, don’t move yet!
Xiao Liu, find a position seven meters away and don't move!" Yu Qingyang directed the three people to use the Pythagorean theorem to turn the right angle.
Junior high school students all understand the Pythagorean Theorem, but their practical application may not be so clear.
However, it is just a layer of window paper. Once it is pierced, there is nothing mysterious about it. It is a very simple application of mathematical geometry knowledge.
Xiaojiang and the other three were like puppets, guided by Yu Qingyang step by step, using a measuring tape to connect a right triangle.
"Oh...that's it!" Only then did Xiao Jiang and the other three suddenly realize that it was so simple.
"Yes! It's that simple!" Yu Qingyang laughed.
"Manager Yu, what should we do next?"
“Then just extend the line!
Follow this method and draw a rectangle on this piece of land!
This is the foundation of our living area!
Then use soil to raise it, compact it, harden it, and build a house on it..."
"Brother Yu, does hardening mean concrete?"
"Yes! This entire area is poured with concrete..."
Yu Qingyang took Xiao Jiang and three others to spread the gray line in the living area.
Then Yu Qingyang took out his mobile phone and said, "Brother Lu, let your four different elephants come over and try to live!"
"Okay! I'm just waiting for your greeting!" Village Chief Lu said with a smile.
Village Chief Lu is really interested, and I don’t know how he does his job.
I really got twenty cars with four different shapes.
Although a village is raising funds to buy a car, it is not easy to raise enough money to buy twenty Sibuxiang cars!
Twenty cars are not alike, one million smaller.
"Hurry up and come here! It's right at the entrance of your village to the lake!" Yu Qingyang also said with a smile.
After hanging up the phone, he explained to Xiao Jiang and the others: "You three are responsible for recording the number of cars! You must remember it well!"
We must resolutely reject their unreasonable demands!"
"I know, Brother Yu! How to count?"
"Draw straight characters on the book, draw a line when pulling a cart, and one of them will record the number of carts with you!" Yu Qingyang explained to them carefully.
It’s normal for fresh graduates to not understand!
I think back then, when he first started as an intern, he was not much better than them.
There is still a difference between the knowledge learned in books and its practical application. You need someone's guidance before you can learn how to apply the knowledge you learned in books to your work.
After a short time, Village Chief Lu arrived at the scene with his people and Si Buxiang.
Village Chief Lu jumped down and asked proudly: "Brother Yu, tell me how to do it!"
"Haha, Brother Lu, are you still planning to drive the car yourself?"
"Isn't this their first time working? I will take them to practice for a day today!" Village Chief Lu said with a smile.
"Transport the soil from there to this place! Pour it into the gray line I spread, and it costs three yuan a load!"
"Okay, no problem! Start now?
By the way, this is the accountant of our village, you know him, let him record the number of cars with you!" Village Chief Lu said, pointing to a middle-aged man in his forties.
"Let's start!" Yu Qingyang nodded.
Village Chief Lu’s car was purchased by the village committee with funds raised. The driver’s salary is deducted from the money earned, and the remaining money is divided among the whole village according to the amount of investment.
This saves Yu Qingyang and the others a lot of trouble. They don't have to record the number of cars separately. Invoices are so troublesome. They only need to record the total number of cars.
Village Chief Lu climbed up to Sibuxiang and drove towards the excavator.
These people are all driving without a license. They are constructing in the river anyway, and it is a technical job to overturn the car.
Just know how to put the gear in gear, how to accelerator, and how to turn the steering wheel.
You will become familiar with it after driving it a few times.
This is the same as driving tractors and agricultural tricycles in rural areas. There are very few people who follow the regulations and apply for a driver's license.
Fourthly, this thing itself does not comply with the regulations and is a three-no vehicle.
That is to say, a few good years will soon be eliminated.
These four products are not products of the blank period of China's construction machinery. When the country is carrying out infrastructure construction, it is a supplement to domestic construction machinery.
Jiefang trucks and Dongfeng trucks currently produced by the country have a very small load capacity.
It is equivalent to cars such as Foton pickup trucks in later generations.
It will not be until next year or two that domestically produced heavy-duty trucks will be launched on the market, gradually replacing Sibuxiang.
Yu Qingyang stood aside and watched for a while, waiting for everything to get on track before turning around and leaving.
Then we came to Lujia Village.
Yu Qingyang and the others live in Lujia Village, so naturally the roads in Lujia Village should be built first.
I don’t blame people for commenting in my hometown. The good road was filled with potholes and ruts thirty to forty centimeters deep spread all over the road.
Not to mention rainy days, even good weather is not easy to walk.
The first step in building a road is naturally to level the roadbed.
Supervisor Liu Gong and others were also on site. Building bridges and paving roads was a great deed for good deeds in ancient times.
Supervisor Liu Gong and others stood on the roadside, chatting with the villagers and accepting their thanks.
According to the villagers, this road has not been repaired in more than ten years, and the villagers usually use shovels to pad it.
Yu Qingyang and the others used excavators to build the road, which caused a lot of noise.
The old men, old ladies, eldest girls and young wives in the village stopped playing cards and stood on the roadside watching the fun.
"This big guy works quickly!"
"What is this machine called?"
"Call it an excavator! It's so powerful and it works so fast!"
"If the people in the city had the skills to bring such a big machine, our road would probably be repaired in a few days..."
The villagers stood on the roadside and talked about it.
The children in the village also gathered in front of the excavator to watch the strange things.
Although excavators had come before when the lake embankment was being built, they were working on the lake embankment. Now they are working in front of their house. These children are very excited.
They gathered in front of the excavator, laughing and joking.
These children don’t know what is good or bad, and it is very dangerous to laugh and play in front of the excavator.
Parents don't have this awareness of the danger, and they don't care. They think it's normal for children to play.
Yu Qingyang hurried forward and shouted: "Whose child is it? You guys stay away from the excavator!"
Everyone hides aside. If I see who comes closer, I will catch him and hand him over to your teacher!"
When Yu Qingyang shouted, the children who were playing in front of the excavator fled in all directions.
Teachers are still a great deterrent to children!
After driving away the children, Yu Qingyang said to the crowd watching the fun: "Fellow folks, uncles, aunts, uncles and aunts, brothers and sisters, it doesn't matter if you just watch the fun, you must take good care of your children!
Don't let your children lean forward, as you have seen, they can dig through such a hard road, and if this happens to them, they will break bones at the least!"
Then he told Xiao Shen and others: "Xiao Shen, the three of you must take good care of you, not only to watch the excavator work, but the most important thing is to pay attention to safety.
