Why Li Mengxi and Guan Yu haven't returned yet is because they are busy surveying.

The infrastructure required to build a military camp requires barracks. That is, a place for soldiers to stay. They cannot always live in tents. The durability of tents is an issue. They will break down after being exposed to wind and sun for a few months.

However, tents coated with tung oil and tightly sewn are very expensive, and it is not affordable to use tents as barracks.

Therefore, there must be barracks and residential areas.

Moreover, it is not enough to have a barracks. Li Mengxi felt that there must be a large canteen, a toilet, and a place for entertainment. After training, the soldiers can play chess, chess, or chess. Because Li Mengxi also could not think of it.

Why were there other civilized entertainment methods in ancient military camps?

Military prostitutes are not included. This is too uncivilized and will corrupt the combat effectiveness of the soldiers.

Cuju is a bit fun, but I don’t know if it existed in the Han Dynasty.

Archery is also a recreational sport.

Apart from that, Li Mengxi doesn't know anything else.

In addition to barracks, canteens, toilets, and entertainment venues, there must be bathhouses, places where classes can be held, material storage warehouses, and places for producing and processing armaments. After these basic living needs,

There are various training grounds for mountain warfare training, water warfare training, various training grounds for formation battle training, as well as a horse farm for raising war horses, etc.

Because Li Mengxi's advance design of the military camp was too complicated, and there were too many aspects to consider, one of the public bathhouses alone caused difficulties for both Li Mengxi and Guan Yu.

A public bathhouse is a place for bathing. It is just a matter of building a very large stove and getting some pipes, including clay pipes and copper pipes, and then boiling a furnace of water, which can be used for hundreds of people to bathe.

The stove is not a big problem, the difficulty is the water.

How to solve the problem of water source, whether to use wells or diversions of river water, whether to use wells or diversions of river water, how to send water to high water towers, is an insurmountable problem.

Unless there is a water pump.

Unless, ancient Rome used baths, that is, due to the height difference of water supply, there is no need to build a high water tower. Instead, it is the other way around. There is no need to build a water tower, dig a pool on the ground, boil hot water pot by pot, and then

Just follow the passage and pour it into the pool, that's fine too.

The bathtub problem is solved.

There is no need for a water tower to provide water and other issues. You only need to lead a water channel to the camp, then bury a large copper pot on the ground, lead the water directly into the pot, and then artificially heat the water. The hot water will be boiled directly along the

The trench flows into the pool.

Then, the pool is covered with stone slabs, and the pool is designed into a structure that can drain water, with a drainage channel underneath. In this way, the bathroom is solved.

Then build a house with good sealing effect over the pool, and the insulation effect will be very good in winter.

As for summer, soldiers go directly to the river to bathe in summer without hot water.

The final solution was that diverting water from rivers was much better than fetching water from wells. Fetching water from wells in buckets and boiling water for thousands of people would be exhausting.

And diverting water from the river is equivalent to having tap water, saving the workload of fetching water.

So the final key is to find a slightly lower terrain near Dalu Ze to facilitate the introduction of river water into the camp when building the camp.

It took Guan Yu and Li Mengxi a long time to set up the camp alone, which was slightly lower, flat and open.

Later, the key building that Li Mengxi considered was not the barracks or the school grounds, but the toilet area.

According to Guan Yu's idea, just find a corner and dig some holes.

But what Li Mengxi wanted to build was a high-end toilet built with bluestone and a drainage system that could drain all the dirt out of the camp.

The drainage system is just a gully. Just dig some drainage ditches, bury them underground, cover them with bluestone slabs, and then cover them with soil, which is enough to cover up the smell.

The key question is, where should the sewage be discharged?

Li Mengxi felt that with the production and lifestyle of the late Han Dynasty, it would be no problem for domestic waste to be discharged directly into the lake. There is Daluze next to it, and it would be discharged directly into the lake without affecting the water quality.

However, Guan Yu said that all the excrement and urine should be kept for planting.

Li Mengxi suddenly realized that he had to keep the compost.

But the problem arises. If the sewage is not discharged into the lake, it must find a place to accumulate it. Then the sewage system must be very long and far away from the camp to ensure the cleanliness and sanitation of the military camp.

After a little calculation, we can use clay pipes. It is said that the Qin Shihuang Palace used clay pipes. If we bake some ceramic drainage pipes as thick as gasoline barrels, one and a half meters long, and connect two thousand meters long pipes, there are only four thousand pipes.

Clay pipes, not too many.

Making pottery requires only manpower and firewood, and the materials are only soil, so there is no cost.

The sewage system and toilets have also been fixed.

Li Mengxi also thought of the time in junior high school. The water flow system of the school toilet at that time was a large pool. After a period of time, when the water reached a certain level, there would be a splash and several tons of water would pour out.

The physics teacher told me what the principle of floating is.

What is this floating principle? It can automatically control the amount of water and release water automatically with a purely physical structure. What is the principle?

It seems to be a small ball or something. It has the same principle as a solar water tower and the automatic water supply in a toilet.

The core of the principle is a small ball. Li Mengxi thought he could try it out when he had time to see how to do it.

As a place where tens of thousands of troops are stationed, the most important thing is the barracks.

Based on Li Mengxi's current understanding of the late Han Dynasty's construction technology, manpower and material resources, cost, and other aspects, Li Mengxi believed that it would be good if the barracks could have soil walls and thatched roofs.

The cost of adobe house is very low.

However, Li Mengxi knew very well that it was the end of the Han Dynasty and the Little Ice Age. The temperature was very low. It was low now and would be low in the next few years or even ten years. Winters were very cold. In addition, cotton was not popular in the Han Dynasty, so cold-weather clothing was not available.

The ability to withstand the cold was not strong enough, and the resistance to the cold was slightly weak. Furthermore, Li Mengxi knew clearly that the foundation of the Zhuozhou Army was weak, the manpower and material resources were not rich enough, and there were not many clothes and bedding for the soldiers to keep out the cold.

Taking all kinds of considerations into account, the barracks can be small in size, and it can be extremely hot in the summer, which is fine, but it must be able to keep out the cold in the winter.

We need to consider resisting the cold. The soil wall is strong enough to withstand the cold, so there is no problem, but the roof and thatched roof are permeable to rain and wind, and have poor thermal insulation capabilities.

Li Mengxi thought of the powerful Zhang Fei's house. The house of Zhang Fei's house was very good, with a roof made of rafters and tiles, which was airtight.

Therefore, the minimum standards for military barracks are earth walls and tile roofs.

Considering the organization and management of the army, it is best to have ten people in one house, that is, one ten people in one barracks.

If we consider the cleanliness of our daily style, we should have one bed per person instead of a large bunk bed.

Although it is simple and trouble-free to use bedding, there is no way to check the hygiene. Li Mengxi still wants to fold quilts, and still wants everyone's bed quilt to be as flat as a book. He still has to keep the house tidy. The military camp he is familiar with should be

Is such that.

When Li Mengxi said that there must be a bed for each person, a locker for each person, and a place for daily washing, Guan Yu was very puzzled.

Guan Yu smelled the smell of money. There was a single bed and a locker for each person. Well, it also had to have a lock. The military advisor said that if you were afraid of losing things, you had to have a lock. You also had to have a place to wash and get water into the barracks.

All around.

How much does this cost?
