The aqueduct is so complicated, Han Jiang doesn't know much about civil engineering, so he is purely curious:

"What about the rack?"

In fact, the foreman explained in detail that in order to ensure the water quality, the process of the aqueduct is more complicated than to say.

For Han Jiang's question, he also picked a simple and focused answer.

"Set up the province, the hard pottery burned on the shelf is good to use, or the whole tube, or the half pipe, the shelf does not cost much, and the pottery pipe is fired by our own Yanzhou. Some people also say that the hard pottery pipe is buried in the soil to divert water, but after trying, it is difficult to draw water when it is buried deep, and it is easy to break down if it is shallow and the carriage is pressed. ”

Han Jiang understood, everything is still a matter of materials.

Before the crossing, iron pipes were used for water intake, and cement pipes were used for drainage. At present, if its own Baiyufang uses iron pipes, not to mention pressurization and valves, it is impossible to meet the amount of iron used in the pipes, not to mention the estimated cost of iron pipe production.

The foreman said again: "There is a Xiucai in the Baiyufang who said that thousands of years ago, the pottery pipe was buried in the ground and a picture was drawn. We've tried that way before. ”

"How?"

The foreman thought for a while and replied: "We are rough people, it's not good to say that the scholars are not good, but it's useless." The water is too small, and it takes a lot of water to eat in Baiyufang every day. ”

Han Jiang didn't quite understand whether the Zhou Dynasty had it, but he was sure that the city's water consumption at that time could not be compared with now. "Understand, next time you can say this, it's stupid to read, and the times are advancing."

The foreman grinned and didn't answer.

Han Jiang planned to go to the Baiyufang construction site tomorrow to have a look, and after explaining a few words to the foreman about his new house, he went back to rest.

After going back to the house and going around, he always felt that there was something missing in the house, and Han Jiang came out to see Han Tongqing again.

The ultra-high-cost cold chain box of Han Jiang in the Song Dynasty has been sent to Han Tongqing, and the box was not opened when Han Jiang fell, but was stored in the basement.

"Brother, won't you try the food I sent?"

"Waiting for you."

Han Jiang took off his robe and threw it to a servant, and sat down cross-legged.

Han Tongqing ordered someone to fetch fish.

The fish is a live fish caught in Hangzhou Bay, this kind of fish Han Jiang has never seen, and the locals call this fish aconitum.

Han Tongqing personally cut the fish, and Han Jiang sat on the side grinding wasabi.

Han Jiang said suddenly: "I always feel that something is missing in the house, but think about it, the identities of Ying and Cai are also different, I asked, the experiment has been carried out in the second phase of the final, if nothing else, it can be officially promoted in the second half of the year." The future female doctor saint is not suitable for me to be a servant girl again. ”

Han Tongqing listened: Hehe.

Just laughing, but not saying anything. Instead, he changed the topic: "There is one thing, not many people know about it." Uncle didn't know the details either. ”

"Brother, please speak."

Han Tongqing said: "According to the method you said, Yanzhou tried it by burning it." Later, there were three recipes that could be used, and after I saw it myself, I asked Bai Yufang to use the cheapest recipe. ”

There were still three that could be used, Han Jiang asked, "Be specific." ”

"Well, the first recipe, they found a stone in Hades' Ridge, and after digging up the floating soil, there is a very soft and brittle stone under the soil layer, which can be broken by a strong person with his hands. The craftsmen burned it with lime, which was also an accident at the time, and it was supposed to be mixed with lime and gypsum, but I forgot to mix it, and it turned out to be usable. ”

"Is that okay?" Han Jiang really doesn't understand.

He only knows that it is a certain kind of stone and clay, plus lime and gypsum to make cement, but if you want to do it well, you have to constantly explore the process and formula.

At the moment, as long as there is a preliminary use, as long as the money is in place, the craftsmen will definitely continue to research.

Han Tongqing continued: "It can be used, but the effect is not as good as the most expensive kind. However, because it is cheap, I arranged for it to be used by Baiyufang, and the craftsmen tried it, and it was a good thing. Just a three- or four-story house with wooden pillars as a structure is completely sufficient. The most expensive kind is made of a variety of ores ground with ingredients, and with the addition of steel bars, crushed stone, and clean sand, it can be as strong as a rock. ”

"Well, it's good that the four-story house is enough, as long as it doesn't ruin our family's reputation."

"No, adding half a percent of gypsum powder is far better than using lime mortar and a little rice juice to build a brick house in the past, which has been tried by craftsmen. Baiyufang is just an ordinary house, and the reinforced concrete you said is too wasteful. ”

"That's right." Han Jiang believes that it is right, cost control is important.

Han Jiang suddenly thought that since there was already primitive reinforced concrete, then, hehe.

"Brother, how about you say that we built a ten-story high-rise building, isn't this thing bullish?"

Han Tongqing laughed dryly: "It's still bullish, it's not good to make a fortune in a muffled voice, you have to be in the limelight." It was too expensive, but it wouldn't be better to build a bunker and a half-foot-thick iron gate to hide the gold. ”

"Wonderful, my brother said wonderful." Han Jiang smiled happily.

Han Tongqing stuck a little wasabi and sweet soy sauce and ate a piece of fish, and nodded with satisfaction: "Yes, it's really good." Go back and send someone to send it to a few families that you have made friends, and you personally send some to the palace, just say that it is occasional, don't say where it comes from. There is another matter, Liu Xianlun wrote a letter to you and asked me to detain it. ”

"Something important?"

"No, he wants to do some business with the local natives, and he wants you to support him. I wrote him a note, and he picked whatever our family produced in Yanzhou. This guy is very interesting, a horse of linen and a pair of shoes for one piece of wood, a sharp axe for two pieces of wood. ”

Speaking of this, Han Tongqing laughed: "This profiteer, do you know how big the wood is?" ”

"How old?"

"A kind of self-inflicted aroma, the first-class wood is ten zhang long, and this one is said to cost two and a half cloths and an outer axe, and the thick skin is close to one zhang. After processing, there are also eight feet of good material available, and the tree heart material is even more high-quality fine material. ”

"There is another kind of bigger, I heard that the largest material is nineteen zhang long and two zhang thick. I have never heard of it, but I have already sent five first-class carpenters from the government to take a look, and if it is good to add some money to the natives, I heard that it is not easy to transport it out of the mountains, and it is okay to give ten horses and eight horses of fine linen. ”

Han Jiang didn't understand it very well, but he believed that his first-class carpenter would definitely have results if he went to see it.

Even if they don't know what the name of the tree is, the carpenters will determine the value of the wood.

Han Tongqing instructed someone to bring wine: "Come and drink some, it's okay to get drunk for a few more days recently, and go out less." In the past half a month in Lin'an City, I'm afraid there will be a lot of things. ”

"Understood." Han Jiang also understands.

For such a big thing as Huainan East Road, it is strange not to make wind and rain in the court.

At this time, the words are flowing to seek a new city.

This place is called Yinan City.

It is said to be a city, but it is just a simple earthen fence, and even the wooden stakes are not willing to be used, because the wood here seems to be very good, and it is all money to transport it back.
