As for the industrial category, let's put it aside for the time being. Pang Yu and several other engineers have a more ambitious plan for the industrial layout of the Traverser, but it depends on the results of the exploration of surrounding resources.

The first thing on the agenda was the cafeteria, which included a kitchen and a large dining room for everyone to eat. In this way, everyone does not have to always run to the beach to discuss things in the future, although the bonfire party is very good, but the sea breeze is not good, and some people have already caught a cold.

There is quite a lot of vacant land in the county warehouse compound, so a greenhouse is built in the yard against the wall. Hainan is a hot part of the world, and ventilation of buildings is crucial. The public places for eating and gathering do not care about privacy, and the shacks ventilated on three sides are sufficient.

Another important factor in choosing a greenhouse is that it consumes the least amount of materials and man-hours, and the shed has been built on the beach before, so it is technically more secure. But when they built their huts on the beach, they mainly used modern materials: steel tube skeletons and plastic raincloth tents, while in the compound, Pang Yu planned to use as many local building materials as possible.

The structural supports must be made of wood, the roof skeleton is made of bamboo, and the covering is made of large banana leaves and thatch, which are very environmentally friendly materials and easy to get, but they are not fireproof.

There is no need for drawings, the plan is directly drawn on the ground with chalk mud blocks in a ratio of 1:1, and the structural engineer Chen Jun points the pillar pit on the ground, pads a few bricks as the column base, and erects the wooden pillars prepared in advance, densely puts on bamboo purlins, and then covers them layer by layer with banana leaves, and the last step is to thickly pave the thatch.

The kitchen part is more complicated, it is also a shed, separated from the dining room, its support columns are made of bricks, and the interior is built with bricks and stones according to the requirements of Master Li, including the first half of the chimney is also made of bricks - the second half of the high chimney is knocked with white iron sheets, and the places that cannot be reached by technical means can only be replaced by modern materials.

The kitchen still uses a lot of modern products for the water supply, including a centrifugal pumping machine installed in the well, which is turned on for half an hour every morning to pump enough water for the yard for a day to a large tank installed at a high place. The wells and tanks are sealed with lids to maintain hygiene and to prevent poisoning of the water - there will certainly be locals in the future.

The lower part of the tank is connected to the kitchen and dining room by a guò water pipe, and a sink is installed in the dining room, where a drain tap is housed like a real canteen. When the water flowed out of the faucet, many people burst into tears - after coming to the Ming Dynasty for so long, they could finally use tap water again!

A small water purification system is also connected to a water pipe, using the ion water purification method, and the water flowing from this faucet can be drunk directly - in fact, the local underground water quality is very good, and drinking it directly is not a big deal. However, modern people's physique is more delicate after all, and many people have diarrhea, and the water purifier is much better after it is put into use.

Including Pang Yu himself, more than 20 young men from the engineering team worked in the compound for four or five days, and finally built two sheds, one large and one small, in the "Green Zone" compound. This includes a reasonable flow of personnel, a complete water supply and sewerage system, and strict fire safety measures.

When they saw that everyone naturally gathered in the greenhouse when eating, and the laundry and dishes did not have to be crowded by the well, all the construction workers showed a smile of relief.

This is just the first step in their transformation of Lingao City.

The people's ** is really endless, the front foot just built the restaurant greenhouse, and the back foot Pang Yu received a new engineering order.

"You want to build a toilet?"

Pang Yu looked at the thirties eldest sister in front of him, and a wry smile appeared on his face.

Ms. Hu Wen, the leader of the "Ministry of Women's Rights and Interests", does things vigorously and resolutely, and has a bit of a strong woman flavor, and the girls in the traverser under her leadership have formed a group.

"Yes, Xiaopang, you men don't care, but our lesbians have a lot of trouble in this regard. And you know, most of the girls are arranged in the kitchen, and they are oily and smoky every day, and they get greasy every day, and the damage to the skin is too great, and there is no place to wash them. ”

"The new kitchen is much cleaner now...... Well, but bathing is a real problem. ”

Maybe she has been in the government department for a long time, this lady speaks old-fashioned, she is not two years older than Pang Yu, but she actually followed those old comrades to call him "Xiao Pang", which made the latter very unhappy. However, Pang Yu didn't want to worry about her, because in addition to Hu Wen, there were two other people next to him who happened to hear this topic and immediately walked over.

"Yes, Pang, the hygiene problem is a big problem for all of us, and it must be taken seriously!"

It's Jack and Lao Shi from the health team, and it's really rare that the two of them have the same position.

"It's not a big problem to dig a pit and make a simple toilet with a baffle in a short period of time, but if we live for a long time, we must set up a septic tank, otherwise it will inevitably pollute the environment and even cause infectious diseases!"

"So strict? There was no septic tank in the Ming Dynasty. I think the toilets are even more rudimentary than what we use now, and open defecation is common......"

Pang Yu was not a complete layman in medical and health care, but he was taken aback by the theories expounded by the two doctors next.

-- Everyone carries bacteria on their bodies, and generally speaking, the bacteria in the human body are always adapted to the surrounding environment. In modern times, the bacteria that survive are the lucky ones that have been tested by countless bactericidal drugs. But for the traversers, they suddenly came to this new, unfamiliar environment, and there were no artificial fungicides and antibiotics in this environment.

So, a very practical problem: the germs carried by the traversal are just as much a product of their time as they are. Here they are "superbugs", and the local environment simply does not control them. If these bacteria spread, no one knows what impact it will have on the local ecology.

"It may be a biochemical catastrophe and we will be fine, but the immune systems of the ancient people around us are completely unable to resist the microflora we have brought from the modern era, leading to a large-scale epidemic of infectious diseases! And there is no cure! ”

Doctors always like to talk about things strictly, but Pang Yu didn't dare to say that their words didn't make sense. So far, people have not had much contact with the locals, and it seems that there is no infection. But now that you think about it, you must try to avoid it.

Setting up a septic tank is a very practical treatment method, the intestinal tract in the human body has the highest bacterial content, feces is the main source of pollution, and the fermentation of feces through the guò septic tank can effectively kill most of the germs.

Since the septic tank has been raised to such a height, the construction of toilets has become a priority. However, after listening carefully to Hu Wen's request for a new toilet, Pang Yu couldn't help but smile bitterly.

"Well, ma'am, you're asking for not just a toilet, but a shower...... Still need a relatively private space to deal with some personal matters? …… Of course, electric lights will be installed...... Well, I'll think about it. ”

The functional requirements are so complex that you can't draw a pattern directly on the ground. Pang Yu had to go to Wang Ruobin's machine room and ask him to help make a set of drawing tools, including the No. 1 drawing board, T-shaped ruler and triangle board, although they are all wooden, but because they are scales separated by industrial measuring tools, the accuracy is quite high.

I've been used to computer graphics since graduating from college, and I haven't touched these things for years. Pang Yu carried a notebook with a full set of drawing software, but without a printer and plotter, it was impossible for him to put the notebook on the construction site to compare the construction.

Fortunately, the basic education he received in school was still relatively solid, and it only took one day for Pang Yu to draw a full set of construction drawings, including detailed samples. After that, he lent Chen Jun the triangular ruler of the drawing board and asked him to match the structure, and Pang Yu himself set off to look for building materials everywhere in and out of the city.

Although the scale of the house to be built this time is not large, the grade is not low, and it can no longer be counted with thatched huts. Hu Wen also made a special note when she made a request to build a wall with bricks, and this woman was simple when she touched her mouth, and she didn't want to think about where Pang Yu would find bricks? The bricks used in the kitchen were only available after tearing down half of the remaining walls in the yard, which is far from enough.

Ancient China has a long history of using bricks, and there were bricks in the Qin and Han dynasties, but at that time, bricks had only one purpose in addition to city bricks - to build tombs. In the cemetery of the Han Dynasty, tongue bricks and hollow bricks were even dug up, but they were not used by living people.

Even in the Tang and Song dynasties, when Chinese civilization was the most brilliant, its buildings were generally built with mud embryos. The architectural style of the Tang Dynasty is characterized by "large arches and far-reaching eaves" - this is not only for the sake of aesthetics, but also for the fear of rain splashing on the walls.

Looking back on the history of Chinese architecture, Pang Yu feels that he is quite lucky, just in time to travel back to the Ming Dynasty, where brick was already widely used in residential buildings. The brick-making technology of the Ming Dynasty should be said to be very mature, when Emperor Zhu Yuanzhang overhauled the city wall of Nanjing, and ordered all parts of the country to worship the city bricks. In order to prevent counterfeiting, the bricks should also be engraved with the name of the manufacturer and the place of origin. To this day, on the Ming city wall left behind in Nanjing, the names of those firing craftsmen can still be clearly seen.
