Chapter 850 Don’t forget, this place is my food! Sure enough, how could it be that simple!
In one sentence, Zhao Cheng and other ministers were stunned.
That makes sense!
Even though Ying Chengxuan developed a water mill and a water mill, which greatly increased the speed of refining cement, the manpower and time spent in the material preparation phase still far exceeded what Daqin needed to build roads.
Because the earth and stones used to build roads in Da Qin only need to be burned once with fierce fire, basically no manpower is needed.
Since Ying Chengyu wasted so much manpower and time in the material preparation stage, where did Ying Chengyu save manpower and time?
There is no doubt that it is in the process of construction!
After Zhao Cheng was stunned for two breaths, he asked in shock: "If we did not compact the soil but directly dumped the slurry, how could the road not collapse!"
Ying Chengqi asked back. He said: "All my colleagues have seen with their own eyes the road from Lam Tin Workshop to Lam Tin Ferry."
"What do your colleagues think of the quality of that road?"
Zhao Cheng was dumbfounded!
Zhao Cheng’s experience told him that if the road is not compacted to a hard soil layer, rainwater and vehicles will cause the road to sink, deform, and even become unwalkable.
But the actual judgment of the cement road from Lantian Ferry to Lantian Workshop told Zhao Cheng that even if the heaviest bronze chariot in the Qin Dynasty passed by that road, it would probably not be able to damage the road at all!
The direct conflict between past experience and actual situation made Zhao Cheng want to refute but he didn’t know how to refute!
Ying Chengyu spread his hands and said: "I am not building the road without compacting the roadbed, but only compacting one layer."
"Moreover! What I am building is not Chidao!"
"I am just paying for my own food and recruiting young men in my own city, so that I can work under my command in my own city. I just built the road myself by transporting materials.”
“It’s enough for me and cheap enough, so consider doing more!”
He said it directly to the ministers. Silence fell.
Why did they go to watch the entire cement refining production line of Ying Chengyu?
Why are they here watching workers build the Long Blue Boulevard?
The fundamental reason is not that the cement road is more favored by the ministers, but that the ministers all think that Ying Chengyu has spent a huge price on this road and suspect that the Chang'an Junfu is now on the verge of bankruptcy. But he was holding his neck and refused to accept Ying Zheng's generous reward of money and food!
So, is the quality of the cement road built by Ying Chengyu important?
Just as Ying Chengxi said, this is Ying Chengxi’s food town!
Let alone paving the road with cement, even if it is paved with gold, silver, copper and iron, it is Ying Chengxuan’s right!
Unless Ying Chengyu's move made the people angry, resented the common people, or even caused turmoil, which had a negative impact on the Qin Dynasty, Ying Chengyu could repair whatever he wanted and it had nothing to do with the court.
Whether Ying Chengyu built that road with only hundreds of people and two months as he said is the key!
Ying Zheng said with shame: "Brother Nai wrongly blamed brother Wang, brother Nai apologized to brother Wang!"
Ying Chengqiao smiled and waved his hand: "Brother is worried about brother, I don’t want my eldest brother to worry about me. What happened today is nothing more than that.”
“If my eldest brother is really ashamed, he can choose a good man to serve as the Young Master!”
Ying Zheng abruptly changed the subject: "Brother Wang built this cement road this way. How often does it need to be repaired?"
Ying Chengxuan glared at Ying Zheng helplessly, then shook his head and said: "This road is different from the rammed earth road. It repairs wherever it is broken."
"And this road cannot last forever like a rammed earth road as long as it is repaired properly."
"I think this road should last for more than ten years."
"If it is repaired in time, it may last for twenty or thirty years."
"As for how long it can last, we still have to wait until the construction is successful before we make observations."
Although Da Qin's heaviest chariot is only more than half a ton, it is only equivalent to the weight of an old manle, and the road surface requires The pressure he endured was far less than that of later generations.
However, the quality of the cement produced by Ying Chengxuan was far inferior to that of later generations. At the same time, Ying Chengxuan had not yet developed the dowel rods, caulking plates and other components commonly used in laying cement roads in later generations.
So in Ying Chengyu’s opinion, there should be no problem in maintaining this cement road for more than ten years. If the dents are repaired and the cracks are repaired, it should be able to last for another ten years, but this is already this road. The limit of the road!
Ying Zheng frowned slightly when he heard this: "Can you only persist for twenty or thirty years?"
"If Brother Wang dug deep and tamped it like he built a Chi Road, can this road last longer?"
Da Qin's Chi Road also needs to be repaired from time to time, but as long as it is repaired properly, it can last for hundreds of years. How long!
Although the initial investment is huge, the subsequent benefits will take longer.
Compared with Daqin Chi Road, the cement road built by Ying Chengyu is simply a shoddy project.
Ying Zheng is more or less disgusted!
Ying Chengxuan explained: "Laozi said: The existence of the husband's tongue is not due to its softness. The death of the teeth is not due to its hardness?"
"The cement road and the rammed earth road are just like the tongue. "Tine."
"The rammed earth road is soft, so it can last forever, and the cement road is strong, so it is easy to break."
"Even if it is dug and rammed deeply, the cement road can only last a few years." It has only been a year, but it will eventually be damaged due to cracking of the road surface, and the road surface will need to be dug up and re-paved with cement."
Ying Zheng asked: "In that case, why doesn't Brother Wang build a road between Chang'an Township and Lantian County? Tao?”
"If the money and food in the king's brother's house are limited, brother Nai can order the general to recruit corvettes, allocate money and food, and build this road for the king's brother!"
Ying Chengyu shook his head without hesitation and said: "Build it Chi Dao requires too much manpower and takes too long. Today is a critical moment for Da Qin. We, Da Qin, should use these manpower and time for more important things."
After a pause, Ying Cheng. Xiu whispered: "And this Lantian Workshop is a place for smelting iron and steel. Although most of the vehicles now are handcarts and most of the items carried are ore materials, there may be many heavy vehicles and objects in the future. Walk out of this workshop. "The rammed earth road cannot support heavy carriages and horses, but the cement road can." Or for convenience of use, cement roads are more suitable for Lantian County workshops! ”
Ying Zheng felt a little confused.
Ying Zheng couldn't even imagine what it would look like for an object that couldn't be carried by the rammed earth road.
But this does not affect Ying Zheng’s reception of Ying Chengyu’s first meaning: “Now is a critical moment for our Great Qin!”
Muttering, Ying Zheng His eyes fell on the workers again, and his thoughts were churning inside.
Seeing this, Ying Chengxuan didn’t say anything more. He just stood beside Ying Zheng and stood shoulder to shoulder with Ying Zheng.
Under the gazes of the monarchs and ministers of the Qin Dynasty and the eager (xié) eyes of the Qin guards, the five hundred strong men burst out with energy and strength that even surprised them.
Only twenty strong men carried the ten-foot-long narrow iron plate and placed it at the end of the wooden board, forming a frame structure together with the wooden board.
One after another cement was thrown into the frame, and it only took more than half an hour to completely fill the frame.
The fifty strong men who had just compacted and leveled the land hurriedly put on leather boots, then stepped into the cement pool with tamping pestles, and beat the cement hard with the tamping pestles in their hands, trying to remove as many air bubbles as possible.
After fifty strong men tamped it carefully, six craftsmen wearing leather boots walked into the cement pool with wooden trowels, and used the trowels to scrape the cement surface extremely smooth.
Then, the craftsmen took new wooden boards and iron plates and rushed to the pits that had been dug ahead to continue building the frame.
The fifty strong men who had just compacted the ground had already moved here and continued to level the ground with their tamping pestles.
The movements of all craftsmen and strong men are like standard and precise copy and paste.
Everything happens again and again!
The night fades and the sun rises.
By the time the morning light fell on Lantian County, the same action had been repeated five times by the craftsmen and strong men, and the sixth time had begun!
Seeing that the place where the cement was mixed had moved more than ten feet, Zhao Cheng finally asked in a hesitant voice: "Is it over?"
"The fifteen feet of road has been paved. Doesn’t the craftsmen need to do anything else?”
Ying Chengyu shook his head and said, “How can it be so simple?”
Zhao Cheng secretly breathed a sigh of relief.
really!
Road building is not only a physical job, but also a technical job. How can it be just a matter of tamping, paving and wiping it down?
In just one night, five hundred men and ten craftsmen paved a road of fifteen feet. How is this possible!
Ying Chengxuan continued: "Within six hours after the cement is laid, the craftsmen need to always pay attention to whether the cement is wet and splash water every day for maintenance."
"Cement road energy Whether it is durable or not, this maintenance work is very important.”
Zhao Cheng turned his head to look at Ying Chengxuan with a stiff neck, and asked in an amplified voice: "Is that all?!"
Ying Chengxuan thought for a moment and said: "If the sun is too hot or the weather is bad, , we also need to lay straw mats on the road. "
"At the same time, people should block the area around this road and prevent any creatures from stepping on it!"
Zhao Cheng's voice was louder. How many points: "That's all?!"
Ying Zheng and all the court officials also looked at Ying Chengyu.
After Ying Chengyu thought for a while, he nodded and said: "That's basically it."
"The rest is left to the craftsmen to figure out on their own."
What Ying Chengyu knows There is only so much knowledge.
But Ying Chengyu believes in the wisdom of the craftsmen!
Zhao Cheng didn’t believe what he saw at all!
Pointing to the paved cement road, Zhao Cheng could no longer control his voice and asked loudly: "If a road of fifteen feet can be paved overnight, a road of fifteen miles can be paved in just over a month!"< br>
"How could it take Chang'an Jun two months!"
Ying Chengxuan explained seriously: "The maintenance cycle of cement roads also takes at least fifteen days."
< br>As soon as Ying Chengxuan said these words, everyone was stunned.
In other words, Ying Chengyu said that he spent two months building the fifteen-mile road, including half a month of maintenance?
But it’s just maintenance, isn’t it just pouring some water on it? How many manpower can be used!
Ying Zheng suddenly asked: "If this road is built from Xianyang to Helu City, how much civilian power will be needed?"
"If Xianyang City and Helu City can be connected by this road, How long does it take for our elite troops from Great Qin to reach Helu City from Xianyang City?”
