Little Jinzi "resumed work", and Uncle Liu's young apprentice Pan Xiaosong was about to leave the army. Zhou Yan felt that he seemed a bit redundant. Taking advantage of the opportunity when the old man went to the city to purchase equipment, he packed up and went home.
The whole two-story Chinese-style villa at home has been completed. The ground source heat pump system has not yet been installed. An excuse has been reserved, but only a hole has been dug in the yard and covered with cement prefabricated boards.
After returning home, Zhou Yan was just about to take a nap when his father pulled him off the bed: "Son, you have been resting at your brother-in-law's house for a long time these days, it's time to do some exercise!"
After being picked up, Zhou Yan had to follow behind his father, helping to measure, pull the thread, and then draw white lines on the ground with lime water.
After working for a long time, the two men finally completed the foundation planning of the biogas and manure water separation and purification facilities for the pig farm.
On the second day after returning home, before dawn, Zhou Yan was picked up from the bed by his father. He had breakfast early, then pushed him on the motorcycle and went out to buy fruits and vegetables in the town.
When working on a project at home, you need to hire help, pay the wages, and take care of the food. As the only contestant in the family with advanced cooking skills, Zhou Yan naturally shouldered the responsibility of the chef.
When Zhou Yan returned home on an electric donkey carrying a full harvest, the door was already piled with cement and bundles of steel bars.
Zhou Yan glanced at the cement on the ground, and then frowned: The specifications are okay, but the quantity seems to be a bit too much...
"Dad, why did you buy so much cement?"
Zhou Zhenghai replied confidently: "Use it!"
"Isn't the total amount of concrete marked on the drawings?" Zhou Yan didn't know whether to cry or laugh, "The amount on the drawings has already been added with a margin!"
"Really?" Zhou Zhenghai felt a little embarrassed at being told that. He stretched out his rough fingers and scratched his head, "I didn't even know there was a margin left on the drawing!"
Seeing this, Zhou Yan suddenly had an ominous premonition in his heart, and asked cautiously: "The project has already started, has the budget been completed?"
“What is a budget?”
Zhou Yan's heart suddenly sank to the bottom: "A budget is a plan on how to spend money and how much money to spend."
"There's no need to do this, just spend the money!"
His father's matter-of-fact expression made Zhou Yan a little worried: Dad, your son is a sheep shearer, not a mine operator. Those hundreds of small goals are quite a lot, but you can't help but keep doing this!
"Dad," Zhou Yan said with great pains, "the purpose of making a budget in advance is to control the price of the project. If you purchase and spend while you are constructing, it is easy to overspend..."
"Yes..." Zhou Zhenghai nodded as if he understood, "Then can you make a project budget?"
certainly!
After all, Zhou Yan has been doing engineering installation for seven or eight years, and has even passed the first-level construction engineer examination in the field of construction. He is naturally familiar with project budgets.
Seeing his son nodding, Zhou Zhenghai smiled: "Then you make one and let me see and learn..."
Zhou Yan ran to his room, found a budget template from the pile of information, copied it onto paper, and then made a fairly detailed budget based on the prices of equipment and materials he checked a while ago.
"This is the budget, I thought it would be so difficult!"
Zhou Zhenghai said it was easy, but the more he looked at it, the more horrified he became: his son's budget barely included the daily food expenses; before construction started, this Lao Shizi budget could calculate how much the entire project would cost.
.
After reading it, Zhou Zhenghai smiled, folded the budget, and stuffed it into his trouser pocket: "Good stuff! I have to keep it after I finish it!"
Zhou Yan was speechless: "Dad, why do you keep this thing? Isn't the pig farm enough for you?"
"What if I get tired of it one day?"
Well, as long as you are happy!
After the project started, the first thing to build was naturally the biogas digester.
To build a biogas tank, you need to dig a hole first. Originally, you could use an excavator to dig the hole, but with a shot of the Cloud-Piercing Arrow, Mr. Zhou replaced the excavator with manual work. Not only was it time-consuming and labor-intensive, Zhou Yan also had to be dug.
Forced to show off her cooking skills...
Fortunately, the acquaintances from the same village recruited by Mr. Zhou's Cloud-Piercing Arrow were quite capable, and it only took one day to dig a large hole nearly five meters deep.
After that, the bricks are laid and shaped into a container shape.
The helpers in the same village were all migrant workers, and their bricklaying skills were certainly not good enough. It only took half a day to cap the building.
After the infrastructure construction of the biogas digester is completed, the projects are relatively troublesome: the wet and dry separation field and the sewage purification field supporting the biogas digester.
The principle of dry and wet separation is similar to Zhou Yan’s principle of recycling water in the survival training of "Desperate Wolf": pumping the waste residue and waste liquid in the biogas pool into an oversized cement pool covered with plastic film, and using solar energy to evaporate the water
Recycle.
The water recovered in the dry and wet separation device enters the sewage purification field, and is recycled after purification.
Originally, sewage purification equipment was a bit redundant in 2007, but Father Zhou felt that his excrement was discharged outside, which really made him feel a little sorry...
The infrastructure construction of the entire peripheral equipment of the pig farm took almost five days. After completion, taking advantage of the gap, the father and son went to the city to purchase machinery, equipment and materials.
The supporting pipes, valves, booster devices and gas stoves of the biogas digester are relatively easy to purchase and are readily available in the hardware market. However, the mud pumps and anti-corrosion pipes used in the wet and dry separation device are more troublesome to purchase.
Especially the large-diameter Corten steel pipes used in pipelines still need to be customized.
The father and son had no choice but to leave a deposit and return home with the purchased biogas equipment and mud pumps.
It took two days to install the entire set of biogas pipelines, and the father and son happily admired their work...
"Son, the methane gas has been released. Do you want to find a way to solve the problem of feeding materials?"
"all right!"
The feed feeding system is simpler than the water purification system: a screw feeder is used to send the feed to a high silo, and then a small screw feeder distributes it to the feeding devices in the pig rooms...
After the family's pig farm was renovated to look like a modern pig farm, Zhou Yan's father became what the villagers called a "waste".
Zhou Yan was happy to see this situation.
Most people hate the rich, especially those like the Zhou family who suddenly made more than a million dollars, and are more likely to be hated.
And Qiu Fu also led to another phenomenon, fewer people went to Zhou Yan's house to play: going to rich people's houses to play, in the mouth of rural people, how can it be called "flattery to rich people".
And after Zhou Zhenghai "lost a million dollars", more and more people came to play at home.
In fact, Zhou Yan had another way to make his family's sudden wealth less conspicuous, which was to turn the whole village into rich people. Unfortunately, Zhou Yan did not study agriculture and had no intention of becoming a village official, so he could only do it temporarily.
Shelved the idea of making the whole village rich...
Originally, Zhou Yan thought he could stay at home and help his father set up the feeding system before the summer vacation ended.
Unfortunately, things didn't go as planned. Less than three-quarters of the summer vacation was over. "Tool Man" Frank interrupted Zhou Yan's summer vacation with a phone call.
"Boss, I have already found the manpower to set up the company, but this gentleman wants to meet with you for an interview."
"Let's make an appointment!" Zhou Yan looked back at his father and mother who were staring at him curiously.
"Then tomorrow morning?"
"All right!"
After hanging up the phone, Zhou Yan smiled helplessly: "Mom and Dad, there are still things to do in the capital. I can only stay at home for so long during the summer vacation..."
"Don't worry, I can weld the set of materials myself!"
