Chapter 71 Water Supply System

As mentioned last time, Liu Hou took Buqi to visit the water tower, and Buqiu raised a question: Does those cements work? Liu Hou replied proudly:

"Don't worry, I said that if it's harder than a brick when it's dry, it will be harder than a brick."

As he spoke, Liu Hou took him to find a brick wall that had been built a few days ago, pointed to the dried cement in the brick cracks and said to Bu Qi: "Try it yourself." ”

Bu Qi used his hands to pick at the cement, but he could not move anywhere. Bu Qi felt the pain of picking at his fingers, not much different from picking at a stone.

"This, this is called, yes, cement, if this cement is used to build the city wall......" Bu Qi's eyes lit up, thinking of the best destination for cement.

"Hehe, of course, if it is used to build a city wall, then the built city wall must be the strongest city wall in the world." Liu Hou confirmed his thoughts.

As they spoke, they came to the dining hall. It was a large brick house, with a few smaller rooms in the back, and light smoke rising from the chimney on the roof indicated that the houses were on fire, and were probably functional rooms such as kitchens.

There are people coming in and out of the door of the dining hall, and people who come in and out hold a bowl and a pair of chopsticks in their hands. Anyone entering or leaving the dining hall first goes to the dishwashing area next to the entrance of the dining hall to wash the bowl and chopsticks.

He walked quickly to the place where there was a wooden board with the words "Dishwashing Place" written on it, and saw a sink with a copper pipe running through the entire sink, and there was a copper thing on the copper pipe every other step.

It was this thing made of copper that attracted Bu Qi, and Bu Qi didn't recognize what it was, but to his surprise, the person who came to wash the dishes walked up to the sink and twisted a small bar on the top of the thing, and the water flowed out of the small mouth under the thing.

Bu Qi was taken aback and asked, "What is this?" Why does water come out? ”

A soldier who was washing dishes glanced at Bu Qi strangely and said, "Of course there is water flowing out of the faucet, how else can it be called a faucet?" ”

"Faucet, what is faucet? Why does water come out? Bu Qi asked again.

But the soldier ignored him, washed the dishes, and left. Liu Hou came over and explained to him:

"This is the water system that has just been built, and you look at that tall thing, it's called a water tower. The water is loaded on it, and a copper pipe leads it to the point where it flows out of the tap. ”

Liu Hou pointed to the high tower not far away, and Bu Qi looked at his hand, and sure enough, he saw a tower about five zhang high. This pagoda is completely different from traditional pagodas and pagodas.

This tower gives people the feeling of being top-heavy, and above the tower is a cylindrical structure about one zhang high and two zhang in diameter, and under the cylindrical shape are four "stone pillars" that lead to the ground.

All day long, the tower was gray and gray, and from a distance, it looked like four long thin legs against a huge bucket, completely devoid of beauty, only indescribably weird.

"This water tower is made of the cement I just mentioned, which is the hard ash when it dries. Of course, this cement alone is not enough, sand, pebbles, and most importantly, steel bars are added in the middle as the skeleton of the building. We call this mixed thing reinforced concrete.

I dare to pack a ticket, even if you find the best trebuchet in Soochow and bomb it for three days and three nights, you won't be able to knock it down. ”

"How can this reinforced concrete be so strong?"

"You don't need to doubt this, if you are interested in it, you can learn from the craftsmen in the future, didn't that person say, 'There must be my teacher in the threesome', you have to learn not to be ashamed to ask."

"This is what Kong Sheng said." Buqi Khan said.

"Okay, okay, I'm digressing again, or is it going back to this water tower, do you think that thing on the top of this water tower looks like a giant bucket?"

"Could it be, could it be ......" Bu Qi couldn't believe that there was such a big bucket in this world, and someone in this world would put a bucket so high.

"That's right, it's essentially a bucket of water, and that's what it's meant to hold water. If you look at it, the wooden trough next to it is the device that transports water from the well. ”

Only then did Bu Qi discover that there was a wooden trough next to the so-called water tower, which led to the top of the water tower and connected to a well underground.

"Is this a keel waterwheel?" Bu Qi stepped forward quickly, saw the structure in the sink, and asked in surprise.

"That's right, this is Ma Jun's improved keel waterwheel, Ma Jun you know. It can pump well water to the water tower above. Liu Hou followed and explained to him in due course.

"Ma Jun? Could it be that Wei Guo gave Ma Jun in the matter? Bu Qi was amazed.

"Hehe, you also know him, he is now with me, specializing in all kinds of agency information."

"No wonder, no wonder, Qiu has heard that Ma Jun is not good at speaking, but he is good at ingenuity, good at studying all kinds of organ news, his skills are superb, and he likes to study several inventions in the legend of Lu Ban. With him here, it's no wonder that His Royal Highness the Crown Prince has repeatedly come up with amazing things. ”

Bu Qi thought that he had found a reasonable explanation for the appearance of so many strange things in the Shu army.

Liu Hou didn't care what he thought, he pointed to a runner connected to the wooden trough and said:

"Just by pushing this wheel, you can pump water to the tower. Come and show it to the step-sama. ”

After one of the pro-soldiers agreed, he called a few pro-soldiers, ran to the side of the runner, and one of them pushed a push arm to push the runner up.

So, Bu Qi saw that the well water was scraped by the scraper, and it was continuously sent to the water tower.

"This runner can also be pulled by cattle and horses, and I plan to build a big windmill to push it in the future, but because the process is more complicated and the amount of work is relatively large, I can't build it for the time being.

Now the craftsmen have more important things to do, so put this plan on hold for the time being, and when the craftsmen are free later, they will build a big windmill and rely on the wind to push the waterwheel, and then there will be no need to waste manpower or animal power to do this. ”

"Wind power can work, too?" Bu Qi is really getting more and more confused.

"Absolutely, whether it's wind or water, it's a kind of power, or energy, and it can help us work. These things involve some physical knowledge, or the knowledge of things, and you can go to our research institute to learn about it when you have the opportunity in the future, these things are very important, and you must understand them. ”

"Yes, His Royal Highness the Prince." Bu Qi respectfully saluted Liu Hou again, he is now more and more curious about this prince and this Shu army.

"This water tower and water wheel are the main part of the water supply system, and you look at this copper pipe." Liu Hou pointed to a copper pipe that came down from the water tower.

Bu Qi followed Liu Hou's finger and found that after the copper pipe that came down from the water tower went underground, there were several forks, and one of them led to the sink.

"These copper pipes carry water from the tower to various places, including the kitchen at the back and the dishwasher at the front. You look at that sink, the water that comes out of it is coming down from the tower.

We install a faucet on the water pipe, this kind of faucet can be understood as a valve, when you open it, it will release the water, when you close it, it is equivalent to blocking the opening of the copper pipe to prevent the water from continuing to flow out. ”

Ps. There will be a more one later
