Li Tangshan, an MIT, has also read a lot of books about road construction.

In ancient times, there were no modern mechanized tools, and only manual filling methods were used.

1. Use a trolley to send soil, and manually fill the soil with shovels, rakes, hoes and other tools.

2. Starting from the lowest part of the site, from one end to the other end from bottom to top, the thickness of each layer of virtual paving, when tamping with artificial wood, the sandy soil shall not be greater than one foot, and the cohesive soil is two inches;

3. When the deep and shallow pits (grooves) are connected, the deep pits (grooves) should be filled first, and the shallow pits should be filled in layers after being leveled. If it is filled in sections, it is handed over and filled into a stepped type. The wall foundation and pipeline backfill are backfilled and compacted with fine soil on both sides at the same time.

4. Artificial ramming with 60~80kg of wooden rammer or iron, stone rammer, by 4~8 people to pull the rope, two people to ram, lifting not less than one inch, one ramming half ramming, in order.

5. Large-area manual backfill is tamped with tamping equipment. When the two equipment are parallel, the distance between them shall not be less than two zhang, and the distance between the front and rear shall not be less than half a foot on the same ramming route.

With the help of Li Tangshan, a high-achieving student, Chidao was quickly completed with quality and quantity.

In 220 BC (the twenty-seventh year of Qin Shi Huang), Li Xin gathered an army of 100,000 and greeted the emperor outside the city of Xianyang.

The three princes and nine secretaries, hundreds of civil and military officials, all gathered together, and Chang Hu Wujing led all the subordinate officials, set up altars to worship, and prayed for blessings.

Woo –

Bursts of war drums and horns, like thunder roaring in the sky, the emperor's chariot guard of honor camp, all the way mighty, from Xianyang Palace.

Hundreds of thousands of Xianyang people, tiptoeing and watching, there is no longer a scene of cursing tyrants in film and television dramas, but the joys of the grateful people spread one after another, spreading everywhere.

Today is the day when the emperor goes out on patrol.

The new policy, national law, new grain and many other issues related to the foundation of the people's livelihood in Daqin have been solved, and only the repair of the emperor's mausoleum and Afang Palace remains.

The First Emperor made a great raid in his life, the purpose of which was to suppress the dark tide of the restoration of the Six Kingdoms.

This time, the first emperor went out on patrol, there was no sound of the chariot, there was no maid to accompany him, dressed in armor, like a commander-in-chief, holding a Tai'a sword, majestic, how high-spirited.

According to the instructions of Chang Hu Wujing, it is time to worship the heavens and pray for blessings.

There is no way, in this year, it is not so much to pray for the sky, but to see it as the people of the world.

"Meng Tian ......"

The ministers and hundreds of officials stood aside, holding a wat board, and the right prime minister Li Si whispered, "Your Majesty is driving the expedition in person, wearing armor, and the old man can't help but think of the time when we followed the emperor to the south and the north decades ago. ”

"The merits of the first emperor are eternal, if Your Majesty wants to sweep away the remnants of the Six Kingdoms, he should do so."

Meng Tian had already changed into a general's attire, wearing a bronze forged helmet on his head, and his one-foot-long helmet spear glittered in the sunlight.

The two ear guards with a straight five inches are exquisitely curved, a silk red cloak is worn on the body, smooth and flat, and the two sea pearls on the clasp are personally rewarded by the first emperor back then.

At first glance, Meng Tian looks much younger.

At the end of the ritual of sacrificing to the sky, the first emperor mounted his horse, clamped his legs, and galloped straight towards the 100,000 army with the sound of horses' hooves.

"Your Majesty's ......"

Li Xin and Meng Tian sat on the war horses, hugged their fists and said: "The 100,000 army has been assembled, and it will be reviewed by His Majesty personally." ”

Qin Shi Huang rode on a horse and shouted: "The soldiers have worked hard! ”

The soldiers shouted: "The First Emperor is mighty! ”

Qin Shi Huang rode his horse and continued to shout loudly: "The soldiers have worked hard! ”

The soldiers shouted loudly: "Great Qin will win!" ”

.......

The soldiers sang: "Old Qin, go to the national disaster together, go to the old Qin, restore my rivers and mountains." Blood will not be shed, death will not be truce! There is Daqin in the west, such as the sun rising, a hundred years of national hatred, and the vicissitudes of life! The world is in turmoil, how can Corning! Qin has a sharp soldier, who competes with it! ”

When the sentence "Old Qin, go to the national disaster together" was sung again on the land of China. Lao Qin's unbroken backbone, an irreproachable past, is immersed in the sorrow of historical indifference. The footprints left on the snow, the scholars who hurried in the wind and snow, but chanted, and went to the national disaster together. The blood will not be drained, and there will be no truce. Only then did the long-cherished wish of reunification be realized. And this sentence "Serve Lao Qin, go to the national disaster together", as a national declaration, inspires every Lao Qin person from time to time. This sentence is the "national oath" of Great Qin's unification of the six countries.

The Yan and Huang clans have always been a collection of suffering and war, but dare to ask how many generations dare to roar the tragedy and grandeur of generations between the poor mountains and bad waters like the old Qin lineage? Since ancient times, the Han Dynasty has been rebellious, the Jin Dynasty has been reckless, the Sui Dynasty has been scheming, the Tang Dynasty has been greasy and cumbersome, the Song Dynasty has been cowardly, the elements are barbaric, and the Ming and Qing dynasties have been blunted. Only Lao Qin is resolute, martial, trustworthy, and simple. Open the waves of the Hereafter.

A country and a nation need a spirit, that is, the common values of our Chinese nation, and this spirit needs to be deeply rooted in the hearts of the people from top to bottom and flow into the marrow of the entire nation. Whenever the country and the nation are in danger, every Chinese son and daughter at home and abroad shouts slogans and stands up for the country and the nation.

Li Tangshan is not a kind of luck to witness and participate in the establishment of the Qin Dynasty.

Qin Shi Huang re-stood on the parade, he waved his hand, and the army moved towards the west like a stream. Li Tangshan was assigned by General Li Xin to be under Zhao Tuo and Yan Le to protect the safety of King Qin. Qin Shi Huang used Li Tangshan, Zhao Tuo, and Lü Wen to build highways to start the first parade, and began to tour Longxi and Beidi.

Zhao Tuo said to Li Tangshan: "Brother-in-law, I'm so moved! I was moved to tears for the first time! Great Qin is strong! ”

Li Tangshan said: "The Qin Dynasty is too powerful! ”

At this time, Li Tangshan looked at Zhao Gao and Yan Le not far away, and nodded to himself! Li Tangshan had no choice but to nod to them, he had always wondered in his heart, what was their purpose?

Zhao Gao raised his hand and motioned for Li Tangshan to come over, and Li Tangshan came immediately and walked in the direction of Zhao Gao: "Senior, what are you looking for me?" ”

Zhao Gao nodded and said, "Li Tangshan, it's not a big deal!" You and I are both people after 2,000, and there are not many people here who can chat? ”

Li Tangshan also feels the same way: "It was really difficult to communicate at the beginning, but now I have adapted to life here. It's been several years since you came to Daqin, what is your purpose? ”

Zhao Gao glanced at Li Tangshan and said with a smile: "Li Tangshan, don't worry, we won't mess around." Our goal is the relics, and we have yet to find the whereabouts of any of them. ”

Li Tangshan glared at Zhao Gao and Yan Le and thought, "The purpose of this Japanese is to find holy relics, what do they want holy relics for?" Has their dream of militarism not yet been extinguished? That is another suffering for humanity. ”

Li Tangshan replied to Zhao Gao: "What is a holy thing? My family doesn't even know the record. How do you know? ”
