Chapter 37 Paddy Field Transformation Plan
There is a sketch drawn on the rock wall of the cave. The elders have already seen that it is the terrain outside the cave. There are caves, small rivers, jungles, and some things that were not there before.
At this time, Luo Chong was thinking about how to plan the large open space in front of the cave in the future.
The cave faces south and north. Starting from the entrance of the cave, there is a small river more than 900 meters to the east, and a jungle more than 1,000 meters to the north. There is also a jungle about 1,500 meters to the west, which is the direction of the Bald Tribe.
This piece of land is very large, 2,400 meters long from east to west and about 1,000 meters wide from north to south. According to the 667 square meters per mu of land, this piece of land is nearly 3,600 mu, equivalent to the area of 333 football fields.
Wodetian, if all of this is planted with rice, it is estimated that the people of the entire tribe will not be able to eat it all until they die.
Of course, it is impossible to plant all rice, let alone plant all of it. Now even how to plant it is a problem.
You should know that although this area is large, it is all dry land, and rice must be planted in paddy fields. Just transforming these dry lands into paddy fields will be a big project.
With sufficient food and a safe environment, the number of humans will grow exponentially. The original Han tribe had only 52 people, plus the 9 people bought, and the 6 children who were born in the past few days that Luo Chong took away, plus the 30 people from the newly joined Tree Tribe, there are now 97 people. The caves of the Han tribe are gradually unable to meet the living conditions.
Therefore, in the future, houses, residential areas, rice fields, pepper fields, wild vegetable fields, farms, pastures, large warehouses, granaries, bronze smelting areas, and wood processing plants will be built on this land. So many facilities must be placed on this land, and they must be well planned.
The first problem to be solved is the transformation of paddy fields. Planting rice requires a lot of water, and pastures also need water, otherwise how can the forage be harvested and how can the two cute gluttons be raised.
The best way to turn dry land into paddy fields is to dig canals to divert water, which is relatively easy, but it is unrealistic to irrigate such a large area of land, unless the canals are widened and deepened to become rivers. Therefore, an artificial river is very necessary, which is what the Han tribe really needs.
The simple plan is to build a square town with a side length of 400 meters in the middle of the vacant land, and put the residential area, farms, warehouses, granaries, metal smelting areas, and wood processing plants in this town. The whole town is expected to provide living conditions for at least 5,000 people, and the maximum limit can accommodate 8,000 people living together.
This scale is undoubtedly huge for the current Han tribe, but Luo Chong did not plan to build it all at once. Modern real estate developers know that the project is divided into stages, so it makes no sense that Luo Chong would not know how to do it. It can be completed in a few years.
A moat was dug around this 400-meter square town, and the excavated soil was used to build the city wall. The city wall did not need to be too advanced, just a soil-covered brick structure, with rammed earth inside and a layer of bricks outside. This can effectively protect the rammed earth from being eroded by rainwater, and not many bricks are needed, which can greatly save the workload of burning bricks. Isn't this because there are few people? All aspects must be considered.
Then, with the moat as the center, an artificial river was dug to divert the water from the river, and then a loop was dug. The water from the small river flowed into the moat and then flowed back from the moat to the small river. This formed a huge water network. Some small canals were dug along this water network to irrigate the entire plot.
The preset width of the moat and the artificial river is 4 meters. In this way, the water flow rate of the eight or nine-meter wide river on the east side will remain unchanged, but the river channel will be narrowed by half. Therefore, in theory, the water flow rate of the artificial river will increase by more than double, which will facilitate the installation of some water conservancy facilities, such as waterwheels.
Digging an artificial river will produce a lot of earthwork, but the earthwork cannot be piled up randomly. The earth excavated from the moat does not need to be transported, and can be used to build the city on the spot, while the earth excavated from the artificial river for water diversion is used to burn bricks.
The specific plan is to use the cave as the center line, and select 200 meters on each side as the site for the small city. The small river is 900 meters east of the cave. Minus the 200 meters occupied by the small city, so a 700-meter-long, 4-meter-wide, and at least 4-meter-deep artificial river is needed
to dig through this 700-meter-long water diversion river, and the excavated earthwork is directly burned into bricks to prepare for the subsequent city construction. The city can be built in a hurry, but the water must be diverted first, so as not to delay next year's spring plowing. He doesn't want to have to carry water to irrigate the land when planting rice next year. For rice fields that need long-term flooding, that is simply unrealistic.
The second phase of the project is the excavation of the moat, which is 1,600 meters long, 4 meters wide and 4 meters deep. However, there is no need to rush this matter. Anyway, the cave can still accommodate people, so there is no need to work so hard.
The third phase is to ram the city wall. The city wall is preset to be a trapezoid with a bottom width of 4 meters, a top width of 2 meters and a height of 5 meters, with four gates, one on each side. There are 1.5 meters high arrow slits on the outside of the top of the city wall, and wooden fences are used inside, so that it is 6.5 meters high from the outside and 5 meters high from the inside. The width of the top of the wall is 2 meters, which can easily accommodate 3 people walking side by side.
Such a thick and tall city wall, coupled with a 4-meter-wide moat outside, in this era, absolutely no one can attack it.
In fact, people are not the most terrifying. Luo Chong's main defense is wild beasts. What if a moa or a saber-toothed tiger comes? If it is just a simple 2-meter-high brick wall, it is not even as tall as a moa. It is useless. Luo Chong does not want the children in the city to be playing, and suddenly a moa jumps in from outside the wall to eat the children, or some wild beast breaks through the wall.
What is the purpose of the wall? The wall is for defense.
The fourth phase of the project is a 700-meter-long backwater river. The excavated soil can be burned into small bricks and used to build houses and various facilities in the city.
The entire project is expected to be completed within 3 years at the latest, otherwise Luo Chong is afraid that there will be no room for people to live in the cave.
This is fucking, if there is a large excavator, it will take at most half a month to dig this 3,000-meter-long river, but Luo Chong needs 3 years, emmm
The four-meter thickness of the city wall occupies an area of 400 meters, which means that the actual area of the city is a square of 396 meters.
The city consists of four 15-meter-wide main roads, which intersect in pairs and form a "well" shape, dividing it into 9 areas in a nine-square grid. The middle is a square for sacrifice or gathering, and can also dry rice.
The residential structure is all one-story brick and tile houses, each covering an area of 100 square meters, that is, a small square of 10 meters x 10 meters.
The house faces north and south, and the space of 4.5 meters wide and 10 meters long can be divided into 3 rooms. Excluding the thickness of the wall, each room is 3 meters wide and 4 meters long, which is about the same size as a modern bunk house. There are
bedrooms at both ends and a kitchen and dining room in the middle. The bedrooms at both ends are built into a kang, which is connected to the stove in the middle kitchen. As long as the stove in the middle is always burning, it can provide heat to the bedrooms at both ends at the same time.
The rooms are all large bunk beds like kangs, and each bedroom is expected to accommodate at least 5 people.
Such a house type can accommodate an adult man and two or three adult women, plus six or seven children, a household of at least 10 people. There is no other way to distribute it this way, because adult men need to hunt, and there are too many casualties, so the ratio is seriously unbalanced.
The remaining 5.5 meters wide and 10 meters long yard can be used to build a thatched shed or a small storage room to store firewood, food, tools or weapons, and a toilet. It all depends on your own preferences, you can make it whatever you like.
Within the 400-meter-long and 400-meter-wide city wall, in addition to the four 15-meter-wide tic-tac-toe main roads, there is also a 16-meter-wide ring road around the city. Together with the thickness of the city wall of 4 meters, the outer perimeter is 20 meters wide. The net size excluding the thickness of the city wall is equivalent to the current four-lane road.
In this way, nine square areas with a side length of 110 meters were divided. Eleven brick houses with a square length of 10 meters could be arranged in a vertical row. A 5-meter-wide alley was left between every two rows. A total of nine rows could be arranged, with 11 households in each row. That means there were 99 households in one district, and at least 10 people lived in each household. One district could accommodate 1,000 people.
The nine districts in the city, except for the middle where no houses were built to be reserved for the square, the eight outer districts could be built in this way, so the city could accommodate up to 8,000 people.
However, Luo Chong had never thought that all eight districts would be inhabited. He didn't even have 100 people now, so he wouldn't build so many houses at once. He would build them when people came.
According to Luo Chong's budget, the city only needed to accommodate 5,000 people, and the remaining four districts would be built into warehouses, metallurgy, breeding, and woodworking districts.
The nine districts were built in batches, and it would take more than ten years to build them slowly.
