On Yunsha Island, people continue to carry various materials and items.

Because of Jiang Yichen's joining, everyone is much more relaxed. But Rao was like this, and the whole process continued until about six o'clock. By this time the sun had set, and sweaty people were scattered around the platform outside the cave, wiping their sweat with towels while panting and resting.

Various packing boxes were stacked on the south side of the platform, and after a simple separation, some small ones, such as consumables, were moved into the cavern.

The rest was left in place for the time being, and was covered with tarpaulin to prevent it from raining at night.

Large items, fir pillars, and stone pillar bases were directly placed near the site of the bamboo building.

There are also various bamboo materials of different lengths and thicknesses, which are currently piled up under the south slope of the platform for processing.

Today's work is done, and the rest of the time is spent eating and resting.

After dinner, everyone cleaned up the tables, chairs, and utensils together. The black-faced Lao Zhang then returned to the big tent in the south with his three men, and Lai Shun'er gave them a solar storage box and two lights for them to play poker and entertainment.

It is said that since the wind-solar hybrid power generation system officially began to operate, due to the abundant electricity, the four portable solar storage boxes that were bought before have temporarily lost their use and have been shelved.

Lai Shun'er reminded Lao Zhang that if you want to smoke in the tent, you should be especially careful not to cause a fire.

Lao Zhang nodded and agreed.

The cave was brightly lit, Kiko and Haruharu were sitting on chairs watching TV, and the goose Weiwei slipped in at some point. Leaned over to the little girl and lay down.

"Whiskers, go out and have fun, don't stay here." Kiko shouted at Weiwei as she pointed to the doorway.

Ever since this guy grew up, he wasn't usually allowed to go into the hole. The reason is also very simple, mainly because of the problem of poop.

"Uh, bar, bar." Weiwei, who was going to go with a bang, lost his temper today, straightened his neck and yelled at Kiko.

"Hey, I'm long. Dare to scold me. Kiko was a little angry. He understood. This goose barking is equivalent to demonstrating and scolding.

He stood up and stepped forward to kick the rude fellow out.

Maybe it's because of the goose's strength, Weiwei's love suddenly became excited. Flapping his wings and shouting. to express strong protest.

"Oops. Kiko, you just let it stay here, Weiwei is very well-behaved. Isn't it? Qingqing said, reaching out to stroke Weiwei's goose head.

In order to prove that Qingqing's evaluation of it was very correct, Weiwei really settled down, folded his wings, and obediently lay back on the ground. Slightly closed his eyes, his head enjoyed the touch of Qingqing, and he no longer paid attention to Kiko.

Xizi had no choice but to explain to Qingqing the reason why the goose was not allowed to move in the cave.

"Okay, if there's something, I'll clean it up." Qingqing continued to shield and condone Weiwei, her fingers sliding down the top of its head and touching its chin.

"Okay, you white-eyed goose with no conscience, I've fed you so much delicious food for nothing."

Kiko shook her head and muttered dissatisfiedly. But seeing the inseparable appearance of these two, he had to let the goose stay like this first.

At this time, Jiang Yichen was strolling outside with Lai Shun'er and Shi Suo'er, turning on the flashlight to check the situation nearby, and at the same time discussing some specific things at work.

Regarding the tap water system proposed by Lai Shun'er and the idea of grading water lifting, Jiang Yichen felt that this method was good and simple to implement.

And there is no need to worry about the water quality in the transition pool, because as long as the bamboo building is inhabited, it is actually in a process of frequent water change, which is not essentially different from the flowing living water. At most, you can clean the bottom of the pool at regular intervals.

This time, there is also a custom-made stainless steel water tank with a capacity of 600 liters, which is ready to be hung on the side roof after the main project of the bamboo building is built.

The actual positioning of the bamboo building is a permanent and comfortable residence, even if a small concrete building is built in the future, the bamboo building will not be abandoned, so the corresponding living facilities must be improved as much as possible. So Jiang Yichen nodded and agreed to this plan.

Since the matter of water ingress has been properly handled, Jiang Yichen talked about the discharge of domestic sewage from the bamboo building, if you dig a pit and discharge it directly, although the number of people is not large at present, there should not be any major problems in the short term, but everything should still be a little forward-looking, and the future situation should be taken into account.

Untreated domestic sewage contains a large amount of feces, paper scraps, pathogenic insects, suspended solids and chemicals in laundry detergent, etc., which are directly discharged into the ground, which will cause severe pollution to the soil structure and groundwater, and then affect the environment and people's health.

According to the relevant information, the usual treatment method in the city is to build a septic tank at the sewage outlet, which is a treatment facility that uses the principle of sedimentation and anaerobic fermentation to remove suspended organic matter in domestic sewage.

The sewage enters the septic tank and settles for 12 to 24 hours, which removes most of the suspended solids. After more than three months of anaerobic fermentation and decomposition, the organic matter in the sludge is decomposed into stable inorganic matter, and the easy raw sludge is converted into stable cooked sludge, which changes the structure of the sludge and reduces the moisture content of the sludge. The sludge is then regularly removed and transported out for landfill or use as fertilizer.

Lai Shun'er said that he had seen these things too. Originally, the traditional slurry mixed septic tank was commonly used, which had a simple structure, but the fermentation and decomposition efficiency was low, and it was easy to leak after a long period of use.

Now the more popular is the FRP septic tank, because it is the use of factory mass production, there are small size, high efficiency, strong sealing, corrosion resistance, high compressive strength, quick and convenient installation, no post-management and many other advantages, and it is said that the use of brand-name products for up to 50 years.

The price is not too expensive, about 1,000 yuan per cubic meter for a small capacity, like the situation on the island, it is enough to get a four-cube one. As for the brand and model, he has already checked the relevant information on the Internet and has a preliminary choice.

Since this is the case, then there is no need to think too much, and the configuration is in place in one step, saving you trouble in the future.

Jiang Yichen and the two finalized this plan. And explained that Lai Shun'er then contacted Director Shen of the logistics department, told him the brand and model, and asked him to purchase it as much as possible.

Next, Shi Suo'er took Jiang Yichen and the others to the north slope of the platform, where the ground is mostly a stone structure.

"The matter of steaming and boiling bamboo last time, I pondered a lot of riddles, came up with a local method, and found a place. Well, you see, here it is. ”

As he spoke, Shi Suo'er hit the flashlight pillar to the ground, where there was a naturally formed groove about twenty centimeters deep.

Bamboo needs to be steamed, and its function is to remove xing, and the second is to kill insects and eggs, so that the use of the bamboo can last for a long time. Jiang Yichen and Lai Shun'er both knew this truth, but they didn't quite understand what he meant now.

"Oh, you're saying fill this trough with water and throw the bamboo in it and boil it. So how do you heat it? Lai Shun'er carefully looked at the stone groove and asked suspiciously.

According to the length of the bamboo, the two ends of the trench are blocked with stones and mud, and the water is carried and poured in. But how to boil water?

"That's what I thought, let's pull the gas tank and the gas stove over, set up a pot next to it to boil water, boil it and pour it inside. Also, I put together a few more earth heaters and connected them with wires, so that the temperature is just enough. Shi Suo'er confidently said his own plan.

As for what kind of earth heater it is, he sold it for the time being, and only said that everyone will know when the time comes.

Jiang Yichen felt that this was a good method, otherwise in order to cook bamboo, he would have to order a long iron tin sink, not to mention the trouble of transportation, and the utilization rate in the future would be very low, and it would take up space and be wasteful.

As for other specific details, just let Shi Suo'er think of them, and they don't bother to bother with this brain.

Several important matters were discussed, and the three of them returned to the cave base.

In the cave, Kiko and Qingqing are still watching TV, and the variety show on the screen makes the two laugh.

The big goose Weiwei bent his neck, and a pair of small black eyes stared at the screen, seemingly full of interest.

"Let's rest early, and we will officially start work tomorrow, which is very tiring." Jiang Yichen said to everyone.

"Brother Chenzi, we're not tired. Besides, it's only eight o'clock, and I go to bed a little early. By the way, there are just enough people, or let's exchange two circles of what kind of cultural mahjong. Kiko blinked her eyes and raised the building yì.

Usually there are only three of them here, although the three-person mahjong can also be played, but it always feels not so authentic.

Lai Shun'er and Shi Suo'er also agreed.

"Hey, all the Jing gods are pretty good." Jiang Yichen was a little surprised by this, after all, he had done a day's physical work.

But when I thought about it, I was relieved. The benefits of the island's diet to the human body are obvious, not only is the physical energy sufficient and the recovery is fast, but also the impression of Xizi and Lai Shun'er has never been sick for more than a year, not even a cold and fever.

So he had no choice but to comply with public opinion and agreed to play two hands. But the statement cannot be made more than ten o'clock in the night.

Kiko cheered and ran to the shelves to get the card box.

After a while, four small Great Walls were set up on the square table, and the four of them sat down to start learning skills, and the cave suddenly resounded with a crisp collision sound.

Qingqing thought it was too noisy and got up and turned off the TV. I went to the basin stand in the corner again, poured hot water and washed it briefly.

Then he said hello to Jiang Yichen, took Weiwei out of the cave, and went back to his tent to rest.

At the card table, Jiang Yichen turned his head and glanced at the 20-inch LCD TV, saying that this screen is too small, and there is no shortage of electricity now.

When Lai Shun'er, Xizi and others heard this, they were naturally very happy, and praised it again and again that it was indeed a good idea. The mahjong tiles in the hand are also rubbed more energetically......)
