I Want To Be Qin II

"I want to be Qin II ()"!

"promise."

Nodding slightly, the three sat down.

Especially Fan Zeng, he naturally knew that Ying Gao himself was a master who never came to the house for anything, so since such a person was recruited, he must have something important to do.

What's more, the colleagues are the general Meng Tian and the great craftsman Gong Shuqing who presides over the Xianyang South Road.

Ying Gao was not so bored as to talk to them.

As soon as the three of them were seated, a waiter brought over tea and snacks. For a moment, the atmosphere in the shogunate became more relaxed.

After all, Ying Gao and Meng Tian already belonged to the high-ranking officials of the Great Qin Court, and they were considered familiar with each other. Naturally, there was no stranger, and Gong Shuqing and Meng Tian had worked together for a long time.

Naturally, there is no suppression between each other.

.........

After taking a sip of tea, Meng Tian put down the teacup, then cupped his hands towards Ying Gao, and said, "I don't know why General Ying has summoned us here?"

Hearing this, Ying Gao put down the teacup, smiled at Meng Tian, ​​and said, "I summoned all of you here for one thing, and that is the construction of Chi Dao!"

"Can Master Gongshu tell the general about the current construction of Xianyang South Road in detail?"

Most of Ying Gao's understanding of Xianyang South Road came from the report on the bamboo slips, and he did not go to the construction site to take a look in person.

Therefore, all he knows is a number.

"promise."

With a nod in agreement, Gong Shuqing bowed his hands to Ying Gao and said: "For more than half a year, the minister led the craftsmen and the slaves who came in a steady stream, and only completed the preliminary work of Chidao in Shu County and Berkshire. .”

At this time, Gong Shuqing stood up, walked to the map, turned to Yinggao, and said, "My lord, start from where we are standing and go all the way to the mountains of Jiangzhou, Anhan, and Langzhong. The excavation is over. I am planning to excavate From Langzhong to Nanzheng."

"Our plan is to go from Nanzheng through the old road, Chencang, to Yongcheng, the old capital of the Great Qin Dynasty, and then from Yongcheng to Xianyang. This is the general plan of Bashu Road in Xianyang!"

Following Gongshuqing's explanation,

Skimming over the map, Ying Gao got a rough idea of ​​the general route map of the Bashu Road in Xianyang. He knew in his heart that this road was the Chencang Road, the old road and one of the five great roads of the Great Qin Empire, the Longbei Tunnel one-third of the distance.

Judging from the map, such a design is reasonable.

"There is no problem with the route design of this rushing road. The difficult problem now is to fill the gully and build embankments where the road may be flooded."

There was a look of seriousness in Ying Gao's eyes, and he turned to Gong Shuqing and said, "In Xianyang, cement has been produced. We just need to wait for a major breakthrough in iron smelting technology, and we will be able to fill the gullies and build embankments."

"It is even possible to build guardrails along the way to maintain the integrity of the road and prevent the occasional loss of control of the horses and horses."

"As for the paving of Chi Road, I thought we could abandon the original method and adopt asphalt and gravel paving methods. In this way, it is easy to repair and can also speed up the construction of Xianyang Bashu Road."

Only Fan Zeng knew a thing or two about cement, but he still knew nothing about asphalt, while Meng Tian and Gong Shuqing knew nothing at all.

Hearing Ying Gao's words at this moment, he couldn't help but look at Ying Gao, especially Gong Shuqing's always flat eyes burst into light, staring straight at Ying Gao.

They can imagine the word crushed stone and iron smelting technology, but it is the first time they have heard of cement and asphalt.

Seeing Gong Shuqing open his mouth, Meng Tian also looked over quietly. He, the general, did not understand this term.

"General Ying, what is cement? What is asphalt?"

Hearing this, Ying Gao smiled, and then started to popularize science with Gong Shuqing: "Cement is a mixture of lime and volcanic ash, which can be mixed with water to form a slurry, which can harden in air or in water, and can mix sand, Materials such as stone are firmly cemented together."

"Concrete made by bonding crushed stone with it not only has high strength after hardening, but also can resist fresh water or salt water erosion. It can be widely used in water conservancy, construction and national defense."

"However, it needs to be used with iron to form reinforced concrete, which can be considered strong and can last for more than ten years or even a hundred years."

"As for asphalt, asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt. Natural asphalt is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used for paving roads, etc."

"Bitumen is highly viscous and fluid, and it is a waterproof, moisture-proof and anti-corrosion building material!"

Speaking of this, Ying Gao took a deep look at Gong Shuqing, and warned earnestly, saying: "Natural asphalt is stored underground, and some of it forms ore layers or accumulates on the surface of the earth's crust. Contains any toxins."

"However, just in case, during the process of using it, slaves may not care about it, but all people from our Great Qin Kingdom must take precautions."

"promise."

Nodding in agreement, from what Ying Gao said, he saw a smooth road for the construction industry, but he was still a little curious and puzzled about asphalt and cement.

It's just that he knows that cement needs a breakthrough in iron smelting technology, and Shanggongfang and Shaofu are tirelessly conquering it, and cement is far away in Xianyang.

At this moment, the only thing he could see was asphalt.

With this in mind, Gong Shuqing cupped his hands towards Ying Gao, and said, "Dare to ask General Ying, where is the asphalt, can I take a look at it?"

Although Gong Shuqing was shocked by the prospect Ying Gao described, he knew in his heart that no matter at any time, what he hears is not what he sees.

Only if he saw it with his own eyes would he believe it.

Ying Gao glanced at Gong Shuqing, and said, "It's just north of Langzhong, above Jiaming. The reserves here are huge, enough for Daqin's road to run through the entire Central Plains."

"You order to go down and let the slaves prepare to pick river sand, and then when I go south from Jiaming, I will teach you how to use cement and other things to build embankments!"

"promise."

Nodding his head in agreement, Gong Shuqing was overjoyed. He knew in his heart that if what Ying Gao said was true, it would be a great change for Daqin and the construction industry in the Central Plains.

And this change was unveiled by him, which made Gong Shuqing so excited that he couldn't help himself.

Watching Gong Shuqing leave, Meng Tian glanced at Ying Gao, his eyes still full of surprise: "Will you take this seriously?"

"Naturally!"

Ying Gao took a sip of tea, put down the teacup gently, looked at Meng Tian calmly, and said, "What good will it do for Ben to deceive Gong Shuqing?"
