"It's just that the three walls together are 1,400 meters long. Isn't the amount of work a bit too large for the Qingque tribe?"
Yang Cheng's brows were furrowed, and his fingers unconsciously tapped the bamboo tube filled with water in his hand.
Let Yanhu and Cangshi cut down trees for digging piles.
Between the two ground piles, it is used to build a stable wall.
Before the advent of lime, the best material for building walls was bricks. Bricks made the walls the strongest. However, under the current tribal conditions, it is completely unrealistic to burn large quantities of bricks.
As for using wood and vines, it can be used to block the attacks of ferocious beasts, but it will not work when facing people. It can be broken by burning it with a little fire.
Not to mention, now in the tribe, everyone's excitement about making fire by drilling wood has not subsided. Every time they barbecue, they don't take the fire source from the original burning fire, but directly drill wood to start a fire and start a new stove.
With everyone so excited, Yang Chengdu was worried that the wall would be accidentally set on fire by the clan members before it was built.
Maybe you can use another method - making adobe!
Adobe is a square block made of clay. Its construction method is also very simple. It is to mix soil, plant ash, and gravel together, and then put it directly in the sun to explode.
On Earth, many rural areas still maintain architectural houses built with adobe.
Clay is easy to find.
Yang Cheng had noticed that the land under the Qingque tribe's feet was all yellow soil, not black soil.
To make pottery and build adobe, you just need to use local materials.
However, if you build adobe, the problem arises again.
Yang Cheng simply made a calculation.
Want to resist the invasion of ferocious beasts or warriors from other tribal totems.
Just ordinary simple adobe is not enough, it has to be enlarged and thickened.
The adobe made is a large adobe that is twenty centimeters thick, forty centimeters wide and eighty centimeters long.
Assuming that the wall was built to be three meters high and half a meter thick, it would require more than 300,000 pieces of adobe.
There are now fifty-three people in the tribe. Yang Cheng previously selected thirteen people and drew totems on their chests. If nothing happens in the next few days, they will all awaken successfully.
Then the number of totem warriors came to twenty-nine!
Already more than half of the tribe's number!
However, even if the number of totem warriors in the tribe has increased, the labor force of the totem warriors is still equivalent to six ordinary tribesmen. All tribesmen in the tribe have become proficient in various technologies, and the efficiency of making adobe has become very high. Two thousand pieces of adobe were made.
The time spent on building the adobe will take more than four months, almost five months!
This does not include the time it takes to transport the dried adobe to the required location.
Taking into account the cloudy, rainy, thundering and windy weather, autumn has passed and winter has entered, with insufficient sunlight.
Then the time to build the adobe will still be delayed, and it will take more than six or seven months...
Not to mention, the totem warriors are required to hunt, weave nets, cut down trees, inspect the tribe's security, trade with the vine tribe and so on.
Based on this calculation, it will take almost ten months to complete and transport the adobe bricks...
This is not possible!
It actually takes about a year to build a wall like this!
How can we strengthen the tribe and lead the tribe back to the ancestral land?
Yang Cheng cursed inwardly.
"My thinking is wrong. I must be thinking wrong. I am a time traveler. It takes so much effort to build a city wall. Wouldn't it embarrass the time traveler?!"
How did the ancients make walls?
By the way, this is it!
A certain text he had learned in middle school suddenly flashed through Yang Cheng's mind!
"Shun Fa was raised among the acreage, Fu Shuao was raised among the building blocks, Jiao Ge was raised among the fish and salt, Guan Yiwu was raised among the scholars, Sun Shuao was raised among the sea, Baili Xi was raised among the city..."
Yang Cheng's eyes became brighter and brighter, and he murmured: "Banzhu...Banzhu..."
Yes, you can use the version building method!
Compared with the method of making adobe first and then gluing the adobe together with mud to build a fence, the block building method is much simpler!
Save labor and time!
Banzhu is a technique for building walls. It refers to building an earth wall by sandwiching the earth between two wooden boards and pounding it firmly with a pestle to form a wall.
It only needs to use boards to support the outline of the place where the fence is to be built, and then put the mixed mud directly into the space enclosed by the boards, and finally solidify the mud barriers.
For example, the Lintao Qin Great Wall and many sections of the Great Wall after the Han Dynasty were built with rammed earth.
This method of building walls lasted until the Qin, Han and even later dynasties.
After Yang Cheng thought about the version building method, his eyes became brighter and brighter, and he felt more feasible.
On Earth, most of the walls Yang Cheng saw were steel bars, cement, and bricks.
But the version building method is basically rarely seen.
So when Yang Cheng was thinking about how to build a wall just now, his first thought was to use bricks to build it.
If there are no bricks, I would like to use adobe instead.
Now that I think about it, he went too far!
Think of it but not necessarily do it. Yanhu and the others are still cutting down trees!
Yang Cheng planned to let them clear the surrounding trees first, so as to save time when digging the foundation and dealing with the trees on the foundation.
Now!
Go find the clay first and make the pottery first.
Yang Cheng took care of things with both hands and didn't delay things at all.
"You two, stop arguing. Let's go and take me to the river to have a look!"
Yang Cheng said to the two beast-eared girls who were still arguing.
When the two beast-eared girls heard that Yang Cheng said they wanted to go to the river for a visit, hesitation appeared on their faces.
"Wu, isn't it good? There are many ferocious beasts on the other side of the river."
"Yes, Wu, it's too dangerous."
Regarding the concerns of the two beast-eared girls, Yang Cheng used a small provocation tactic and said:
"Back then, your father and I were not afraid of those ferocious beasts when we went to the river. Why are you two now so afraid after becoming totem warriors?"
The two beast-eared girls jumped when they heard this:
"Afraid? How could you be afraid!"
"Yes, my father is not afraid of ferocious beasts. How can I be afraid of ferocious beasts?"
"Wu, come up quickly, I will take you to the river now!"
Under the urging of the two beast-eared ladies, Yang Cheng got on the "salanquin".
Then... he regretted that he should not have provoked Yan Lin and Xing.
I saw two beast-eared girls, watching Yang Cheng sit on the net and holding on to the vines.
He moved very quickly, put two long wooden sticks on his shoulders, ran at a speed of 100 meters and five seconds, and rushed towards the river!
