Chapter 849 A Total Spendthrift! How Do You Think I Saved My Manpower and Time?
Under Ying Chengjiao's forcible pulling, Ying Zheng followed Ying Chengjiao with a smile on his face as he went downstream along the river bank.
Not long after, another wave of heat came, and Ying Chengjiao breathed a sigh of relief, saying cheerfully: "We're here!"
Looking at the blast furnace standing in front of him, Han Cang asked in confusion: "Doesn't it need iron to build that road?"
Ying Chengjiao shook his head: "Iron is useless. When the steelmaking technique is perfected, I will fill the road with steel bars."
"The blast furnace in front of you is not used for ironmaking, but for burning materials needed for road construction."
The Qin monarchs and ministers who heard Ying Chengjiao's words were secretly amazed.
That's steel!
If anyone has a steel sword in their home, it can be regarded as a family heirloom, helping generations to charge and kill enemies and win military merits.
In the end, you want to bury the steel in the road?
Prodigal son!
A total loser!
As for Ying Chengjiao's second sentence, it made the Qin monarch and his ministers completely confused.
Ying Zheng couldn't help but ask: "The materials needed to build the Changlan Avenue need to be calcined in a blast furnace?!"
Ying Chengjiao nodded and said: "Brother, you are right."
Ying Zheng:...
Brother, can't you hear that I am questioning you, not asking you? !
Pointing to the river bank, Ying Chengjiao introduced: "The various materials that have just been ground into fine powder will be transported here by water."
"After unloading the ship, the craftsmen will mix all the powders except the slag powder in proportion, and then put them into this furnace to calcine at high temperature. After the mature material is formed, it will flow out from this outlet."
Following Ying Chengjiao's gesture, Ying Zheng saw that the lower hole of the blast furnace that was supposed to flow out molten iron was opened a lot larger, and what flowed out was no longer molten iron, but molten stone slurry!
Ying Chengjiao continued to walk downstream along the pipeline, saying as he walked: "The calcined clinker will flow along the pipeline all the way to this place to cool down."
"Then the craftsmen will smash the cooled clinker, crush it with a water pestle, grind it with a water mill, and finally mix it with slag powder in proportion."
"The final product is what I call cement!"
"Although this cement is not very useful now, it is enough to support my daily transportation."
"When I have mastered the art of steelmaking, I will study this art more!"
The cement made in this way is enough to meet Ying Chengjiao's current requirements, so that fully loaded carts can travel like the wind on the cement-paved road!
But it is still far from being able to build high-rise buildings and for vehicles weighing several tons to travel at high speeds, and it can make countless civil engineers laugh.
So in Ying Chengjiao's view, this method is just for temporary use.
When the steelmaking technique is perfected and Daqin can produce steel bars on a large scale, Ying Chengjiao will take time to study a better cement production method that is more suitable for Daqin's productivity!
However, Ying Chengjiao's words only made the Daqin monarchs and ministers feel incredible and incomprehensible.
Han Cang's fingers slid across the blast furnace, the water pestle, and the stone mill, and finally pointed to the cement powder. He asked with puzzlement in his eyes: "Chang'an Jun spent so much effort and mobilized so many people, but only made some powder. It is a long way to go before building a road!"
"So, Chang'an Jun is still not satisfied, and he wants to continue to study the powder technique?"
"So, Chang'an Jun also said that it took only a few hundred people to build the road outside the workshop?"
If Ying Chengjiao hadn't mentioned the word "road building materials", the Daqin monarchs and ministers would never have thought that the final product of this assembly line would be the material used to build roads - one of them!
First, pound and then grind, and then use the iron smelting method to consume a lot of fuel and burn at high temperature. After the burning is successful, pound and grind again.
If Ying Chengjiao had not developed the flat wheel water mill and the vertical wheel water mill, the manpower for pounding and grinding alone would have required at least thousands of people.
And after this set of operations, only some powder was refined.
The forging of armor and weapons in the Qin Dynasty was not so troublesome!
Ying Chengjiao smiled and said: "The cement powder has been completed, is it far from building a road?"
"Brother, colleagues, please!"
Finally, after a shocking look at the complicated production line, Han Cang followed Ying Chengjiao's footsteps closely and went to the east gate of Lantian Workshop with Ying Chengjiao.
When Ying Chengjiao and Ying Zheng stepped out of the east gate side by side, the five hundred strong men outside the gate hurriedly bowed and shouted: "Your humble servants greet the king! You greet the Lord of Chang'an!"
Ying Zheng smiled and nodded: "No need to be polite."
"Are you here to build roads for Lord Chang'an?"
The five hundred strong men responded carefully: "Yes!"
Ying Zheng bowed and said sincerely: "It is my fault that you have worked so late at night."
"In addition to paying for food and money, I will give another hundred coins to all the men who work tonight, and allow you to rest for two days after work."
Originally, the five hundred strong men were a little unhappy because they had to work so late at night.
Now, after hearing what Ying Zheng said, the five hundred strong men were at a loss: "This, this, this, working for the king and Chang'an Jun is our duty, how can you give us such a heavy reward?"
"That's a hundred coins! We are just repairing the road late at night, how can we take the reward that we can only get in seven or eight days on weekdays!"
"Since the king and Chang'an Jun have given orders, I will obey them. If the king gives me more rewards, I will not feel at ease!"
Ying Chengjiao said in a deep voice: "The king has given a heavy reward, and you two or three men should serve you!"
"Everyone cheer up and work hard for me."
"As long as the two or three sons work hard with their lives, the reward from the king will be what you deserve!"
Hearing what Ying Chenggan said, the five hundred men were a little embarrassed but happily held their hands in their hands and shouted: "We must fight with our lives!"
Ying Chengyu nodded happily: "Very good!"
"Brother?"
Ying Zheng was a little amused when he heard this, but he followed Ying Chengyu's wishes and shouted in a deep voice: "Pass on my order!"
"Changlan Avenue, construction begins!"
With an order, a thousand guards came out holding torches, dispersing the deep night for the craftsmen.
Zhang Han, Liu Ji and ten craftsmen came out and walked towards the young men.
Under the assignment of Zhang Han and Liu Ji, 500 strong men and ten craftsmen were quickly divided into three groups.
Two hundred strong men held hatchets and, under the guidance of a craftsman, cut down all the shrubs and trees on the planned route.
Two craftsmen held lime powder and followed two hundred strong men, carefully drawing the edge of the cement road along the predetermined route.
Two hundred and fifty strong men holding iron shovels worked hard to remove the soil within the area selected by the lime powder, and piled the removed soil layer on both sides of the lime powder to raise the road shoulders.
Another fifty strong men quickly ran into the workshop.
Seeing this, the monarchs and ministers of Great Qin felt quite calm.
So far, Ying Chengyu's method of building roads is the same as the method of building roads in Da Qin today!
If the Da Qin road construction method was followed, the strong men would continue to dig deeper into the soil until they could dig no more.
Then, all the weeds and chopped trees along the way will be piled on the excavated soil layer and set on fire. After the grass seeds and insect eggs in the soil layer are burned, the soil layer will be backfilled and compacted one by one. , backfill, compact, and cycle back and forth.
However, when the hundreds of strong men rushed out of the workshop, the situation on the scene became different.
Under Han Cang's nose, a strong man sprinkled a cart full of cement powder on the ground.
Han Cang immediately became anxious: "Be careful!"
"It is quite difficult to make this thing. Even if it is sprinkled on a cart, it is a huge waste!"
The strong man pushing the cart looked back blankly, showed a naive smile to Han Cang, and then ran away pushing the cart!
Han Cang was extremely angry and laughed back: "Ouch!"
"You..."
Before Han Cang could finish his words, another strong man pushed a cart full of river sand up to Han Cang, and then poured all the river sand onto the cement powder under Han Cang's eyes!
Han Cang:? ? ?
In the astonished eyes of the emperors and ministers of the Qin Dynasty, four strong men came up with carts one after another, and sprinkled three carts of stones and half a cart of river water on the cement powder that had been made after all the hardships!
Seeing this, Han Cang finally understood: "Are they further processing this cement?!"
Ying Chengqiao smiled and nodded and said, "Han Shangqing is a great talent."
"As Han Shangqing said, sand and gravel need to be added to cement before building roads."
"This is not only to reduce the amount of cement and fill the road with simpler and more easily available materials, but also to allow them to play a supporting role like bamboo slices in the wall, making the road more solid."
However, listening to Ying Chengxuan's explanation, Han Cang couldn't laugh at all. He shook his head and said: "The cement is difficult to make. After it is made, it needs to be prepared again. I don't know how much manpower will be wasted!"
"Looking at the color of this paper (paste), it is quite similar to the surface of the road just now."
"I think Chang'an Lord tamped the road back and forth like building a chimney, and then dumped this material on the surface of the road to make the road as hard as gold and stone!"
"Chang'an Jun uses this strategy to build roads. Although the road surface will be smooth and hard, it will definitely cost a lot of money!"
"It's even more impossible to build a road of more than ten miles with just a few hundred people and two months!"
While Han Cang was questioning, the strong men had already dug a pit about three feet long and one foot deep.
Fifty strong men were quickly separated from the excavation team, holding planks and ramming pestles to simply tamp and level the road. Six craftsmen placed one-foot-wide planks along the route drawn with lime powder. Within the pit.
As Han Cang, Zhao Cheng and other courtiers looked on in shock, a dozen craftsmen directly poured the mixed cement into the pit!
Zhao Cheng pointed at the cement and looked at Ying Chengyu, his eyes filled with shock as he asked: "Chang, Chang'an Lord."
"Just fell in?"
Ying Chengyu nodded naturally and said: "Ang!"
"It just fell in."
Zhao Cheng's eyes widened even more: "There is no need to dig deep into the hard soil, and there is no need to backfill with mature soil and compact it repeatedly."
"Just dig out a foot of soil and then pour this stuff into it?!"
Ying Chengyu nodded confidently and said: "Ang!"
"Otherwise, how could I save my manpower and time!"
