Suffering is like a dark cloud. From a distance, you can see it is black, but when you are under it, it is just gray. - Richter

The biggest food problem that troubled Li Baoqiang was finally solved. His mood cleared away and his brows relaxed.

Li Baoqiang returned to Hope Village. More than ten days had passed. Hope Village was extremely lively. After all, more than 600 people had been added. The population had exceeded 1,000, reaching more than 1,500 people. Although nearly half of them were old people.

The weak, sick and disabled, as well as women and children, but Li Baoqiang was still very satisfied with the current situation. Saving a life was better than building a seven-level pagoda. He had done a great deed.

However, Li Baoqiang always felt vaguely that there was something he had not done yet. When he couldn't remember it, Li Baoqiang stopped wasting his brain cells and stared blankly at the happy and busy people in the village, enjoying the rare leisure time. Candy, the wolf dog, behaved obediently.

Lying next to Li Baoqiang, Candy had grown into a giant wolfdog nearly one and a half meters in size.

Candy stretched out, her red tongue sticking out of her mouth, and stared at the crowd. The villagers in Hope Village were no longer afraid of this vicious-looking wolf dog. In their eyes, this white wolf dog was just a dog.

It's just a large pet. Candy doesn't have the same problems as other dogs and won't bully the weak. In its eyes, only the roaming wild dogs and wild cats in the wild are its opponents.

At this time, a strange face approached Li Baoqiang who was sunbathing. Li Baoqiang stared at this person.

"Hello, village chief, I am a refugee from Guangyuan who just came back from you. My name is Chen Guangliang." The man in his fifties introduced himself respectfully.

"Oh, are you okay?" Li Baoqiang looked at the man.

"There are so many people in the village now, and a lot of feces are produced every day. I have an idea." Chen Guangliang said to Li Baoqiang.

"Oh, please tell me, Lao Chen, don't be so polite." Li Baoqiang encouraged Chen Guangliang.

"I helped others build biogas digesters before, but now that there are so many people eating, drinking, and littering, so much garbage is produced. Biogas digesters can help eliminate garbage." Chen Guangliang suggested.

Li Baoqiang slapped his head, and then he remembered something he had never thought of, which was generating electricity. Life without electricity was really difficult. However, generating electricity had to wait, and the biogas digester could be built first.

"What kind of building did you build? One for each family?" Li Baoqiang asked.

"Yes, it's a small one." Chen Guangliang asked, does Li Baoqiang want to build a big one?

"If you want to build one, build a large one!" Li Baoqiang said domineeringly.

"Okay, the principle is the same. Give me two days to make a plan." Chen Guangliang became excited when he saw that Li Baoqiang supported his idea.

Li Baoqiang was also excited. It seemed that he was still trying to find out the situation of the villagers. There were hidden dragons and crouching tigers here. Don't bury the talents.

Chen Guangliang is indeed a talented person. After two days, he came up with a relatively detailed design plan.

Li Baoqiang called other managers together, and Chen Guangliang also participated. Chen Guangliang was very happy to see that he could also participate in the management of the village.

Everyone was very excited when they heard that a large biogas digester was going to be built. Recently, the construction of Hope Village has been on the fast track, and everything is full of vitality. In the end, everyone decided to build the biogas digester outside the city, and at the same time, the livestock farm was also moved outside the city.

In this way, animal feces can be fully utilized.

Now that the city is densely populated, it is no longer suitable to build other places. After the livestock farm was destroyed by the rats last time, the fat man used traps to catch some goats, hares, and pheasants, and let them go free, and some babies were born.

.

Li Baoqiang did what he said, and asked Zhang Juncai to cooperate with Chen Guangliang to organize manpower, find a suitable site, and dig a biogas digester. Since a large one was to be built, the site was very important, and finally they decided on a potato field fifty meters away from the city wall.

At the location of the biogas digester, the seedlings that had grown small potatoes were pulled out. Everyone was surprised to find that these potatoes were about the same size as sweet potatoes. It was not the harvest season yet, but when it really was, these potatoes would have to be harvested.

What a surprise for everyone.

Chen Guangliang is really capable, and he does things in a very orderly manner. First, let Zhang Juncai prepare the materials. Because he needs to build a 400 cubic meter biogas digester, he needs 8 tons of cement, 16 cubic meters of sand, 5 cubic meters of gravel, and more than 4,000 bricks.

, 100 meters of steel bars, Zhang Juncai has prepared them one by one, and they are already in stock in the city.

Then there is the laying out. Laying out the lines and digging the pit is the first step to ensure the quality of the pool construction, and the construction must be carried out according to the specified dimensions. Chen Guangliang used white ash to draw out the overall plane. Then mark out the greenhouse and livestock farm areas. The livestock farm is on the west side of the biogas pool.

.Determine the center of the biogas pool and draw a circle with a radius of five meters. This will be the future biogas pool. Determine the positions of the feed inlet and outlet and mark them with white ash.

Then they organized manpower to start digging the biogas digester.

First, determine the height of plus and minus zero. The depth of the pit is determined according to the design drawing, that is, the top of the biogas pool and the discharge port are kept on a horizontal plane and 10 cm higher than the ground of the livestock farm. The feed port is super high from the ground 2

centimeters. If the dig is too deep, the biogas pool will be lower than the ground level, which will affect the use of supporting equipment. If the dig is too shallow, the biogas pool will protrude from the ground, causing difficulties in fertilizing pigs and solar greenhouses.

In order to facilitate the placement of pool construction molds or use brick molds to pour the pool body and reduce material loss, the pool pit should be circular and vertical. For areas with good soil quality, the pit walls can be dug straight.

Leave a certain margin on the pit wall, then find the center point according to the positioning stake, and nail a fixed wooden stake. Use one end of a rope to fix it on the wooden stake at the center point, and tie a small hoe to the other end of the rope.

, make a circle so that the length of the hoe blade to the center point is equal to the radius of the pool plus the wall thickness of 6 cm, scrape off the sand that blocks the passage, and trim the pit while digging until it reaches the designed depth.

Immediately after the pit is dug, make the bottom of the pool into the shape of a pot bottom; dig a U-shaped shallow groove from the center of the pot bottom to the bottom of the water pressure room, with a slope of 5%. For places with loose soil, 80 cm below the ground should be placed on a slope.

The size of the soil and slope depends on the degree of looseness of the soil. The principle is that the pit wall will not collapse. At the same time, the inlet and outlet pits should be dug. If there is groundwater, a water collection pit should be dug at the bottom of the pool to facilitate drainage.

Then it is poured with concrete. The bottom of the pool, the wall of the pool, and the lower part of the hydraulic chamber are cast in place with concrete as a whole. The pool arch cover and the upper part of the hydraulic chamber are made of bricks. After several days of continuous construction, the outlet channel, pool wall and water
Chapter completed!
