Chapter 523 Rammed Earth

Xu Chen was so busy every day that he rode horses back and forth for half a month. Both the man and the horse lost a lot of weight.

It was not until early October that all planning and construction of workshops, kilns, and factories were slowly put in place, and the entire resettlement and relocation plan began to get on track.

It is bounded by Jicang River.

The area inhabited by five tribes including the Gonghuo Tribe, the Five Ghost Tribes, and the Lei Tribe on the North Bank has basically remained unchanged, but all the workshops and kilns are arranged here, and most of the workshops are built near the trading area.

On the river beach, construction of pergolas and wooden houses can basically start.

Charcoal kilns, brick kilns, lime kilns and tile kilns are all built near the foot of the mountain.

In these workshops and kilns, people come and go all day long, and thick smoke billows, which only infects this large stretch of river bank with a lively atmosphere.

On the south bank, more than 20 tribes, large and small, are stationed in the four directions of southeast and northwest outside the royal city's planning area to build settlements.

Although the east group and the west group are relatively scattered, you can see people moving stone carts, carrying wood and digging soil everywhere in the area of ​​more than ten miles, as well as the shouts and noises one after another. Occasionally, you can also see people on horseback lifting up

Teams of hunters with flags from different tribes were patrolling back and forth. The whole scene was quiet but moving, busy but not chaotic. It looked very lively.

Each of these resettlement areas has its most lively center.

The core tribes are mainly the Wu tribe, the Gonghuo tribe, the Pi tribe and the Yu Gong tribe.

At the north gate, the Uzbek people occupy an area three miles downstream. They plan to build five settlements and plan to move 200 people there at one time, accounting for almost two-fifths of the Uzbek population.

After this relocation, there were only about 300 people left in the Uzbek tribe.

Although the number of people in the headquarters has decreased, the living environment and life pressure have been greatly reduced. The farmland reclaimed locally can support the better development of the remaining families.

As for the mining and smelting of copper mines, they are the common property of the entire Uzbek people. Even if they move, they still own shares, which will not reduce the distribution of interests among each family. Therefore, no one will resist the relocation.

In fact, the family that is willing to relocate is actually the largest and most powerful family in the tribe. They also seize this opportunity to split up again and expand their voice within the Uzbek tribe.

Because this relocation is in response to Xu Chen's royal city construction plan, in the future we will live closer to the Ba people, Xu Chen, and Dawu, making it easier to travel and communicate.

The other three major tribes also have the same thoughts.

This time, the Ba tribe plans to relocate 30 people. It is not a single family, but will draw some from each of the four families to form a mixed village. The four tribes will form a group and each will build more than half of a small house.

The life of a single family will not affect the relationship between the four internal families of the Ba ethnic group, and their interactions with each other will have their own destiny and foundation.

This plan is also an attempt by Xu Chen, and its success will be gradually promoted in other tribes to provide a model for more tribes to live together in the future.

Counting the Lei Tribe, there are seven tribes in total including the Bameng Tribe. In addition to the Bawu Tribe, the Cang Tribe, the Ji Tribe, the Lei Tribe, and the Hu Tribe will each relocate some of their people, but the Muya Tribe, which has been divided into two tribes, will not relocate.

However, the Hu people were originally small, with only ten men and women in total. Their main purpose of moving here was to burn charcoal and cooperate with the construction of Xu Chen's smelting workshop.

As for the Gonghuo Tribe who was originally on the other side of the river, after a new witch was replaced this time, the new little witch almost obeyed Xu Chen's words and directly moved nearly half of the population to settle near the east gate of the royal city according to Xu Chen's suggestion, occupying

There are seven resettlement sites, which are almost integrated with the resettlement area of ​​the Uzbek people.

The two medium-sized tribes of the Gonghuo Tribe, the Qu Tribe and the Yehuo Tribe, with a population of more than 300, each plan to relocate about a hundred people. Together with the relocation teams of the Qia Tribe, Kun Tribe, Jia Tribe and other tribes, the east gate of the royal city

Suburbs have become the areas with the largest population.

In addition, the number of people relocated by the Yugong and Pi tribes is slightly smaller, only about 200 people each. The main reason is that the tribes are not strong enough to support the development of the tribe and the construction of relocation and resettlement.

Especially for the Pi Alliance, although they have a large number of people, none of the tribes have started building houses and farming. They have no food reserves and no wealth to buy knives, axes and other metal tools, making the relocation difficult. Basically, the relocation of these two groups

, are all based on the core headquarters, with only one or two other wealthy tribes participating.

Xu Chen already knew about this situation at the witchcraft conference.

The great shaman of the Pi tribe wanted to move here as a whole, but Xu Chen vetoed it in the end. The Pi tribe was poor and their own hematopoietic ability was very weak. If they were to relocate as a whole, they would have to obtain a large amount of external support in manpower, material, food, etc., but apart from the Ba tribe

Besides, no tribe can currently support hundreds of people eating, drinking, and sleeping.

Hunting and fishing on the river beach are not the Pi tribe's strengths. If you are not careful in winter, many people will freeze to death and starve to death.

Therefore, Xu Chen suggested that a small part of the Pi tribe should be relocated first, and after these people have established a foothold in Gonghuo Basin by building houses and cultivating fields, the remaining people can move slowly, not in a hurry for a year or two.

Basically these are the general situation of the entire relocation and resettlement.

According to Xu Chen's plan, these tribes will complete settlement construction and farmland reclamation this winter. After planting in the spring, they will slowly begin preparations for the construction of the royal city, firing bricks and lime, preparing wood and stones, and building roads and drainage and irrigation between tribes.

After these basic projects such as drinking water ditches and ponds are completed, large-scale construction of the royal city can begin next autumn and winter.

The end of October soon arrived amid the bustle and bustle, and the relocation sites of various tribes began to take shape.

After a large area of ​​foundation was leveled, trenches were dug.

The fired lime was transported around the settlements by men and women in wheelbarrows and rattan baskets.

After a large amount of wood was cut from the mountains not far upstream of the Jicang River, it was directly bundled into logs and then dragged ashore, scraped and piled to dry.

Men craftsmen from each tribe who were proficient in building houses began to use stones to build the base of the walls.

On the river bank and around some low-lying puddles, there were other men and women digging soil and spreading mud bricks. The gray-brown open space was densely packed with square mud bricks.

Nowadays, mud bricks are no longer made by simply using pottery boards to surround the molds, but brick molds specially made from wood. All tribes use the same size, a square and movable wooden frame. After they are assembled, the mud is put in and wiped.

After flattening and opening the wooden frame, you will find mud bricks of exactly the same size and thickness.

These professional brick molds have been promoted in various tribes since last year, and are now very popular. Moreover, using this wooden brick mold is fast and convenient, so bricks can be laid out much faster than before.

However, not a single mud brick was made for the Ba people's settlement site, because Xu Chen planned to build a rammed earth wall directly on top of the base of the wall.

At present, he has led a group of carpenters to make wooden molds and tools for rammed earth. He leads a group of people to practice making rammed earth near the trading market every day to gain experience.

The origin of rammed earth is unknown. It may have been enlightened since humans used stones to smash things, but it developed during the Shang and Zhou dynasties and flourished during the Qin and Han dynasties.

The oldest Great Wall, a large number of palaces in the Qin and Han Dynasties, and the underground palace mausoleum of the First Emperor are all rammed earth buildings.

The Tao Te Ching says: The nine-story tower rises from tired soil.

In fact, it is the biggest characteristic of rammed earth architecture, that is, it can be continuously stacked layer by layer, eventually forming a very tall and magnificent building.

In rural China, building houses with rammed earth has always been a tradition, extending from the Qin and Han Dynasties to the high-tech era.

Although rammed earth buildings do not look beautiful, they have many advantages. First of all, they are simple to use, easy to construct, green, environmentally friendly, strong and durable, and have excellent thermal insulation effects. They are warm in winter and cool in summer.

Therefore, although rammed earth buildings are old, they have never gone out of style. There are a large number of new-tech rammed earth buildings at home and abroad, which are both beautiful and elegant, environmentally friendly and natural, and are no worse than masonry and cement buildings.

Although Xu Chen has never lived in a rammed earth house, he has seen quite a few houses. In slightly remote rural areas, you can see the remnants of such ancient buildings everywhere.

When he was surveying geology and mineral resources in western Sichuan, he had seen such rammed earth houses being built in local rural areas.

The tool is very simple. It is to use wood to create a rectangular wooden frame according to the thickness of the wall. In fact, it is similar to the movable wooden mold for spreading mud bricks, except that it is larger. When building a house, assemble the movable wooden frame and then slide it inside.

Fill the soil with relatively sticky soil, and add some straw, lime and bamboo thorns for reinforcement in order to make it firm. Then use a pestle to pound the soil very tightly until the entire wooden mold is filled. When you open the mold, you will get a ten-minute section.

Solid earth wall.

Repeat this over and over again, stacking sections one by one, and eventually the walls of the house will be formed.

Because rammed earth does not require water or specialized masons, and is very strong and strong when stacked on top of each other, rammed earth walls are safer than mud bricks. In ancient times, city walls several feet high could be built with rammed earth.

After the triple soil composed of lime, loess and sand is rammed in a certain proportion, its hardness is no less than that of ordinary cement buildings, and even metal tools cannot destroy it.

Therefore, Xu Chen decided to abandon mud bricks in the construction of the royal city. At the same time, he did not intend to use more complex and expensive ceramic bricks. Instead, he adopted this simple and convenient rammed earth construction method.

After making the rammed earth mold, Xu Chen not only had to verify the mold and construction methods, train a group of craftsmen familiar with rammed earth house construction, but also explore the soil suitable for rammed earth construction.

From a natural perspective, the best material for rammed earth is loess, because it has very strong viscosity and is as hard as stone after drying.

But loess also has a huge disadvantage, that is, once it encounters water, it becomes extremely muddy and slippery, and it is extremely easy to stick to each other. Xu Chen walked on the yellow muddy ground after the rain, and his two shoes weighed several kilograms each time.

Every step I take feels like I am competing with the earth. After walking for several miles on the yellow mud ground, my legs will become useless.

The house is originally designed to protect it from wind and rain, so it is extremely afraid of water, so even if it is loess, it is best to add some silt that facilitates water permeability.

However, Xu Chen did not find loess near the Gonghuo Basin. This is a basin formed by hundreds of millions of years of impact. The bottom is full of all kinds of silt. However, because it was washed down from hundreds of miles upstream, and the water flow in this basin is gentle, the arch is

The Fire Tribe is close to the most downstream area, so the sediment deposited is very soft and has very few impurities. It has reached the level of clay for making pottery. This kind of sediment is mixed with a part of slaked lime and then directly rammed into earth walls. The effect looks good.

good.

At least the sections of earth walls that Xu Chen passed through simple proportion tests are very strong. Even if they are not completely dry, you can still feel their thickness and strength.
