I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Liu Tan knew that he would come to ask, and had already given the blueprint to the craftsman, and asked the craftsman to build one according to it.

The hardest part of this is probably the bearing position.

It is not easy to make smooth rotation and wear resistance, but because it is only a model, this product is only made of wood. If it is made of bronze, it may take many days to make a model. As for iron... don't even think about it. up.

There is no blacksmith in Shuofang. Well, when Liu Tan first found out, he was really pleasantly surprised.

But thinking about it, there is nothing surprising. The melting point of iron is much higher than that of bronze. Judging from Shuofang's current situation, it must not be able to support it.

As for other places in the northern border country, there may be ones, but even if there are, I can't afford to wait.

Anyway, the bronze craft is more mature now, Liu Tan doesn't force it, let's lay the foundation first, and then talk about other things.

Wei Buyi watched Liu Tan turn the handle of the turning wheel to achieve the belt in the middle to rotate back and forth. It was so novel for a while, he couldn't help stretching out his paws and turning it twice.

Seeing his stupidity, Liu Tan couldn't help but said: "The principle of this thing is no different from that of a wheel. You can imagine the road as being able to turn, and then the wheel is fixed in one place, isn't it?"

Wei Buyi looked at the steering wheel and then at Liu Tan, hesitant to speak.

Liu Tan was helpless: "Ask whatever you want."

Wei Buyi asked in a low voice: "But Your Highness, the water and the bucket are heavy, right? How can we ensure that this road... will not fall?"

Liu Tan paused for a moment, and suddenly realized that this question seemed... quite important.

There is no metal chain belt in this year, so if you want to use a crank, you must build a metal chain belt that is strong enough, and at the same time, you must ensure that even if the chain belt breaks, it will not fall and cause an accident.

Think about the bucket plus water, no matter how light it is, it still has a certain weight. If it rolls down from the top, it will bring impact. killed.

Therefore, the chain belt must also have an insurance measure, preferably a double-layer chain belt.

Then there is a problem. In this case, the chain belt also needs to use the axle, and it is much more precise than the main part of the crank.

Liu Tan is not sure if it can be done, even if it can be done, it may not be mass-produced, and the long-term use of the chain belt must be very worn, and it may need to be replaced in a short time, so the production capacity may not be able to keep up with the use.

So this method must be discarded, but if this method is discarded, then it is impossible to bring the water up and the empty bucket down while a cranking car is running.

Then we can only use the oldest method, which is divided into two wagons, one for water and the other for empty barrels.

Liu Tan threw the previous plan aside with some regrets, and at the same time comforted himself, don't worry, now the productivity is not up to the mark, even if you want to develop the industry, you must have a foundation, no matter what it is, it is impossible to reach the sky in one step.

After changing the plan, Wei Buyi obviously understood the principle of this thing, in his words: "Oh, isn't this the well?"

Liu is a bit tired of talking, okay, anyway, the truth is the same, there is not much difference.

After solving the problem of the well wheel, oh, the steering wheel, Wei Buyi finally had no problem here, and happily took Liu Tan's instructions to enclose the land.

Liu Tan said to him by the way: "This place, you also have to ask someone to check it first, and then circle it, I want to use it."

What he was talking about was to build the part of the industrial zone. Anyway, Huo Guang didn't care about it, which meant that Liu Tan could do whatever he wanted. Although he didn't get the plan yet, he could enclose the land first.

Because the coal mine hadn't been excavated yet, Wei Buyi's men had time to spare, so they quickly responded and left after seeing them.

At this time, the first batch of bricks came out.

Liu Tan is quite looking forward to this batch of turning heads. This batch of bricks did not use the cooling method of blue bricks. In fact, the difference between blue bricks and red bricks lies in cooling.

Red bricks are naturally cooled, and blue bricks are water-cooled, which is the legendary anoxic cooling.

Red bricks are simpler. Although blue bricks are better than red bricks in anti-oxidation, hydration and atmospheric erosion, Liu Tan said that these red bricks are mainly used to build fences and the like. When there are no problems with red bricks, they will naturally If he wants to use blue bricks, his palace... still needs to use blue bricks. Even if he wants to use red bricks, Huo Guang and others will not agree.

Li Buyan looked very proud when he brought a few bricks. Anyway, he has finished the finished product now, which can be regarded as fulfilling Liu Tan's orders. Not to mention whether Liu Tan will reward him or not. It's very refreshing to feel rewarded.

Liu Tan looked at Li Buyan and chuckled lightly, then asked, "Did you bring both?"

Li Buyi nodded seriously. The two types Liu Tan mentioned were actually red bricks made of clay that had not been trampled by cattle before.

Although that batch of bricks might be useless, Liu Tan didn't ask him to throw them away. They were originally of an experimental nature, and it was just a matter of making a comparison to see if there was any difference in various aspects.

If there is, then follow the new method to continue, if not, it would be nice to have one less process.

After putting down the two bricks in his hand, Li Buyi said, "Your Highness, even though they have been trampled by cattle, there are still air holes in the red bricks."

Liu Tan nodded: "There is no way to avoid this."

These air holes are actually small air holes, which are different from the previous bricks that look like hollow bricks. Small air holes don’t matter. Originally, bricks can’t be used alone, they must be mixed with cement.

Seeing that Liu Tan was not angry, Li Butian felt relieved and said, "Although there are pores, the bricks made later are much stronger than the previous ones."

While speaking, Li Buyan took a large red brick with many holes, held both ends with both hands and broke it hard, the red brick split into two in an instant, exposing the uncomfortable inside.

Li Buyan said: "This one won't work, it's too brittle, so there's nothing wrong with this one."

On the other piece, it can be seen that Li Buyi used a lot of strength to break it with bare hands for a long time without breaking it. In the end, he found a place to cushion the middle part of the red brick and finally broke the red brick.

Liu Tan looked at the two and turned his head, and suddenly smiled.

The smiling Li Buyan was a little dazed: "Your Highness?"

Liu Tan pointed to the first brick and said, "If you take this thing and go to the street as a performer, it will definitely be popular to show everyone breaking bricks with your bare hands."

Li Buyan:? ? ? ? ?

Just when Li Buyan looked blank, Huo Guang walked over and said, "Who is going to perform?"

Liu Tan told what happened just now, and Huo Guang was a little surprised: "There is such a big difference? Fortunately, Your Highness is careful, otherwise using this kind of brick may hurt money and people."

Liu Tan nodded: "Who said no, why did Huo Xiang come over suddenly?"

Huo Guang looked helpless: "This... is the industrial zone plan that His Highness asked for before, let's change it if we don't like it."

Liu Tan took the piece of paper he handed over, looked at the font on it and couldn't help raising his eyebrows and asked, "Did this be made by Huo Xiang himself?"

Huo Guang responded casually: "I asked the people below to make a rough outline, and I refined it a bit, so that they don't know what His Highness likes."

Liu Tan couldn't help but put his hand on Huo Guang's shoulder and said, "We, Xiang Huo, are truly omnipotent."

Huo Guang lowered his eyes to look at the white hand on his shoulder, hesitated for a while and finally said nothing. If it was a different person, he would have been thrown aside by him at this time. This action is really indecent.

However, Liu Tan just kept looking at the picture in this unsightly posture, and Huo Guang even indulged in helping him lift the other side.

Liu Tan began to discuss with Huo Guang in this posture, mainly on the underground drainage facilities. When the city was built in the Western Regions in a hurry, the drainage facilities did not keep up with it. This time, the city will take many years to be visible to the naked eye after it is completed. , basically means that the mine will not be exhausted, and the city will not be destroyed.

So Liu Tan must make great efforts to drain the water, and there is also a commercial area. Originally, Huo Guang didn't set it up. What he thought was a city dedicated to workers and even slaves. What kind of commercial area would he want?

However, he couldn't hold back Liu Tan, so he had no choice but to add it.

Just when Liu Tan was still thinking about where to set aside, Wei Buyi suddenly ran in excitedly and said, "Your Highness, Your Highness, the place you chose..."

Liu Tan couldn't help feeling tense when he heard this, leaned against Huo Guang and said, "What's wrong?"

Holding two stones in his hands, Wei Buyi said, "I found agate mines!"

The corner of Liu Tan's mouth twitched, and just as he was about to say something, Huo Guang turned his head stiffly and asked, "Your Highness, you didn't find any mineral deposits in the place you chose before."

So did you mean it?

Liu Tan: Do you blame me?
