What Su Yang plans to build is a gravity retaining wall, which uses the gravity of the retaining wall itself to maintain the stability of the retaining wall under the action of earth pressure, which is generally made into a simple trapezoid. Pen "Fun" Pavilion www.biquge.info

There was no need for reinforcement to be fortified, a practice that was common in later generations and was also known as a fort.

The width of the top of the wall is generally not less than 40 centimeters, and if it is a finishing and watering or large stone, the top is not less than 20 centimeters.

Of course, this requirement is only for heights below seven or eight meters. When he designed the city wall, he had taken into account the requirements of the retaining wall, which he had to widen and reinforce, as well as use pilasters and beams.

Now it is really necessary to build a retaining wall, and there is a formula, which is to divide the height by twelve, that is, fifteen meters high, and the width at the top is about 1.25 meters.

But in the actual construction process, there is a way to reduce the material, he uses the mountain at both ends of the retaining wall to reinforce, which is equivalent to inlaying the wall into it, and using the trapezoidal shape to unload the load, the worst result is that the retaining wall will sink down, but not collapse.

Sinking is just a trivial matter, sink one or two meters in seven or eight years, and then fill it up, and put a little more effort on the foundation, and the wall will not be broken.

After completion, the inside of the retaining wall will be filled with soil by itself, and this soil will generally sink with it, as long as it does not collapse to the outside, it is a trivial matter.

It is estimated that 1,000 square meters of stone is not enough, but it is not necessary to build fifteen meters high, and a ten meter high is actually appropriate.

In the middle of the retaining wall, a stone arch is designed to enter and exit the mountain, and you can attack condescendingly on both sides of the gate, and then there will be a stone house similar to the city gate to block it, which can basically be safeguarded.

Thinking about it this way, maybe the fifteen meters of the wall is really too high, and it is convenient to lower it appropriately to attack downward.

After a few days, the stone was finally produced, and the foundation had begun to be laid, because it had to be inlaid into the mountains on both sides, and finally the wall was built, which would look like an inverted trapezoid.

However, the mountains on both sides are also part of the retaining wall, and they are connected.

In this way, a lot of stone can be saved by borrowing the mountain, and he preliminarily designed the top width to about 60 centimeters, which should not be a problem.

In modern times, there is a way to reduce the width of the top of the 50-meter-high reservoir dam to about one meter, and the material is all stone, and the gravity trapezoidal design has no problem.

Rubbing his temples, he was born in a non-architecture class, and in the primitive period, he actually changed his career to architecture, as long as it does not collapse, it will be successful, even if it really collapses, it is a natural disaster, not a man-made disaster.

"Su Wu, I want to tell you about the totem sacrifice." The shrine maiden came looking for her.

He slapped his forehead, and forgot about it, and hurriedly called Yan Lan, the merchant girl, and of course, the witch, and the four of them sat down to discuss it together, and this could be made into a table of mahjong.

A modern soul, a witch with a nest, a totem warrior, and a mysterious witch wish, who would have thought that they could get together at this time without any sense of disobedience.

"Miko, tell me about the process, uh, that's what you need to prepare?" Before the totem has been determined, use the East Emperor Bell,

The shrine maiden then said, "If you want the blood of the whole clan, a little bit will do." ”

"That's fine, ready-made, you go on." Su Yang thought to himself, just bite your finger and drip blood, it's simple.

"A beast with a lot of blood, claws, and fangs."

"That's fine, just catch it alive and come back. Also, let's talk about it together. "He doesn't think it's difficult, he can sacrifice tomorrow.

However, Yan Lan and the merchant girl are very calm, because it will not be that simple.

Sure enough, the shrine maiden said, "I also want holy water, glowing beads, and food for the gods." I've got everything else ready, that's all. ”

Su Yang scratched his head and asked according to his understanding, "What kind of holy water, glowing things, and god's food are there, and where can I find them?" ”

Yan Lan interjected, "I've heard of God's food, but I don't know about the other two. ”

The merchant girl thought for a moment and said, "There are no glowing beads in the Dapeng clan's Lord Wuzhu. ”

The witch replied, "I was prepared for the Bloody Wolf Witch Teaching, and God told me so. I know where to find these, and the Blood Wolf found it there, and I'm going to look for it too. ”

Su Yang thought about it, and felt that the holy water and the glowing beads were all foreign objects, and it was estimated that they were useless, and the focus was on the food of the gods, maybe some kind of treasure.

No matter how much, anyway, he will participate in the whole process, not let go of the details, and will try to prepare double copies, how to get the witch, he will paint the scoop for the cottage again.

"Shrine maiden, where is that place you are talking about? How many people want to go, danger not. ”

"It's not dangerous, I've been there, and I have God in my heart, and I'll find these for sacrifice." The pious face of the witch has basically been brainwashed by that ethereal god.

However, both Yan Lan and the merchant girls present were staunch theists.

"Nacheng, how many people do you think is appropriate? How long does it take to go back and forth? "This matter should be sooner rather than later, go early and return early, go to the totem sacrifice in winter, and start training totem warriors next year.

The shrine maiden said, "If the moon is full, it is enough to bring a few dozen people, and the gods will bless us." ”

When Su Yang heard this, he immediately raised the number of people to more than two hundred, how can dozens of people be enough, what if there is danger, there may be some monsters.

"The merchant girl can't go, she's the totem warrior of Jiuli." The shrine maiden added.

When he thought about it, he felt that it was also, whether he believed in God or not, it was better to not fake the hands of other tribes in this kind of thing.

Now the season has entered September, and when you set off next month, when you come back, the weather will turn cooler, and you will still have time to prepare for the winter, and you can also sacrifice the totem.

"Okay, that's it, you get the rest ready first, double. If you have time, you will teach me to learn witchcraft, and you will first learn how to sacrifice totems. I'll take someone with you in a month's time. ”

The matter was settled, and then he went to work again, sending the dried grain to the mountain, preferring to be more troublesome, at least to leave a way out.

When the retaining wall is completed, it may indeed be possible to build a lot of residential houses in the mountains, including a large number of buildings on the top of the mountains.

Later, there was a distinction between identities, and ordinary clansmen lived under the mountain.

In addition, there is a cistern or something, which will also be prepared, no matter how big or small.

However, the biggest problem in front of him is still from the Jianmu tribe, and he still doesn't believe it, can the people of Jianmu keep guarding the rice fields and Xiyi Mountain?

Aren't you afraid that the Jianmu tribe will be attacked? There are so many people coming to Jianmu, and eating and drinking every day is also a big problem.

"Spring, you take someone to contact the small tribes such as Sunset to see how the situation is over there."

As for himself, he won't go, he's not interested in taking the initiative to start a war with Jianmu, if Jianmu comes, he will defend the city, if he doesn't come, then it's just like this! (To be continued.) )
