Chapter 165: Running through the north and south! Zhongnanshan Tunnel!

Tang Dynasty.

Emperor Gaozong of Tang said with envy: "The South-to-North Water Diversion Project has actually been completed?"

"The national strength of China in later generations is truly terrifying!"

"Although I don't know to what extent the technology of later construction projects has developed?"

"But I know that in order to complete such a great project, there must be a strong and powerful country behind it!"

"There is no doubt about it."

At the end of Ming Dynasty.

Li Zicheng looked at the rolling water from the south of the sky and diverted it to the north.

As shown in the schematic diagram, the South-to-North Water Diversion Project has benefited hundreds of millions of people along the route.

I feel deeply moved inside.

Seeing the people on the sky curtain drinking water brought from the south, Li Zicheng said:
"Although this imperial court is truly damnable, I have to admit that I started the uprising because of the severe drought in Shaanxi."

"And now Henan is suffering from a severe drought. The land is barren for thousands of miles. People are eating each other and all the plants and trees are gone."

“There will be countless more victims.”

"Natural disasters have been constant, and coupled with the man-made disasters of the imperial court, I can foresee that the time will soon come for a reversal of power between our army and the imperial court..."

Amid the ancient people's amazement, the sky curtain began to tell the final story.

【And finally, the most difficult project is the West Route of the South-to-North Water Diversion Project. 】

【As we all know, the terrain in western my country is complex, with various mountains and steep hills. 】

【Therefore, the West Route Project of the South-to-North Water Diversion Project is still in the early demonstration stage and has not yet officially started. 】

[The country's top experts spent decades or even hundreds of years on research, which also reflects the rigor of building a super project. ]

[German engineers have to call us experts when they come here! ]

[The planned western route uses a large number of underwater channels and mountain tunnels to connect the western parts of the Yangtze River and the Yellow River.]

[Once completed, it will be able to provide more than 170 billion cubic meters of fresh water each year to many traditionally arid provinces in northwest my country.]

This route is also the most difficult one.

[Before the demonstration is thoroughly completed, the western line project will not be rushed to start. ]

[It is said that the earliest construction will start around 2050, which is the 100th anniversary of the proposal of the South-to-North Water Diversion Project.]

【The real century-long national policy! 】

Sui Dynasty.

When Yang Guang saw this, he couldn't help but frown.

"This South-to-North Water Diversion Project is indeed great, and its achievements are no less than those of our Grand Canal."

“But it’s just too slow.”

"In the future, China is a great country, but it takes a hundred years to discuss a project?"

"Let me be the emperor in the future, and I will get all of this done in 10 years!"

"Let future generations see the speed of the Sui Dynasty!"

At the end of Ming Dynasty.

Li Zicheng saw that the western route project of the South-to-North Water Diversion Project would actually go directly to Shaanxi, where he started his career!
I was also stunned for a moment.

As an expert in guerrilla warfare, he repeatedly fought in the Sichuan-Shaanxi area and walked through the grasslands.

Li Zicheng knew very well how water-scarce Shaanxi and other northwestern provinces were and how much they urgently needed the abundant water resources in the south!

But Li Zicheng was also very clear.

Transporting water from Sichuan to Shaanxi may seem like two neighboring provinces, but the road is long and difficult due to the mountains and hills along the way!

Even for pedestrians walking lightly, it takes a lot of effort.

What's more, how can we drill through the mountain and transport water thousands of miles away?
This is almost impossible!
If it was before, did anyone tell Li Zicheng that water from Sichuan could be transferred to Shaanxi?

Li Zicheng would definitely say that it was a dream.

But now Li Zicheng also realized it.

The Chinese of later generations may actually be able to complete this great and heaven-defying project!

Think of the endless flow of water from the Yangtze River irrigating the farmland in Shaanxi.

I thought of the folks I knew in Mizhi County who starved to death due to drought.

Li Zicheng couldn't help but laugh out loud despite his sadness!

"Although it is not particularly clear what the future Chinese dynasty will be like."

"But it is certain that it was definitely a great dynasty and a great era!"

Think about what the South-to-North Water Diversion Project would be like if it were to take place in the Ming Dynasty.

Li Zicheng also turned his attention to the southwest.

Looking from afar, you can still seem to see the Qinling Mountains.

And a new sky appeared.

The first scene that appeared on the sky curtain made Li Zicheng feel very familiar.

"Ah, isn't this the Qinling Mountains?"

A new sky slowly unfolds in the aerial view of towering mountains.

[The Qinling Mountains start from Baishi Mountain in Gansu in the west and run eastward through southern Tianshui into Shaanxi. It is an east-west mountain range that runs across central my country.]

[It is also one of the north-south dividing lines in my country. ]

[The Qinling Mountains are steep, with a large fault cliff at the northern foot. The mountains are interlaced and the situation is majestic. The rivers cut deep and ravines crisscross, forming many canyons, dense forests and cliffs.]

[The overall environment is very complex and even dangerous! ]

【And this is the geographical dividing line between north and south of our country. 】

[A mysterious and majestic mountain range. ]

[A huge mountain range revered as the dragon vein of Chinese civilization. 】

【It only takes 15 minutes to pass, do you believe it? 】

Tianmu raised this question. The ancients looked at each other in bewilderment.

Han Xin: "I don't believe it, but impossible things always seem to appear on the sky."

Zhuge Liang: "If we can really cross the Qinling Mountains in 15 minutes, then the Northern Expedition will be too easy. How is that possible?"

Li Zicheng: "If we can really cross the Qinling Mountains so easily, we will be invincible in guerrilla warfare."

The ancients simply couldn't believe it.

But in the picture on the sky, a double-channel tunnel slowly appeared.

Qinling Zhongnanshan Tunnel!
[Qinling Zhongnanshan Tunnel is known as the No. 1 Tunnel in Asia! ]

[The tunnel has four lanes in both directions and two lanes in one direction.]

[Starting from Chang'an District of Xi'an City in the north and ending at Zhashui County of Shangluo City in the south, the tunnel is 18.02 kilometers long. ]

[The designed speed is 80 kilometers per hour, and it only takes 15 minutes to pass through the tunnel at normal speed. ]

【开工时间是2001年1月8日，竣工时间是2007年1月20日，耗时6年，花费超过40亿。】

[Finally, the Zhongnanshan Tunnel that runs through the Qinling Mountains was formed! ]

【In view of the complex and dangerous terrain of Qinling Mountains, the railway tunnel was used as an auxiliary tunnel for highway tunnel construction, and the entire super-long tunnel was completed by using long tunnels and short tunnels.】

What does long tunnel short hit mean? 】

[It’s actually very simple. It’s just to divide the tunnel into four parts, and the four units will build them separately and work at the same time.]

[In order to avoid tunnel docking errors during the long tunnel short-distance construction, laser positioning technology is used throughout the process. 】

[The error at the final joint of the four tunnel sections was controlled within 2 centimeters.]

【But drilling a hole is not easy. 】

[First is the deadly rock burst! ]

[When blasting the mountain, workers have to wear bulletproof vests. ]

[But bulletproof vests can’t stop rock bursts, and even more expensive equipment can’t.]

[So before blasting, the route must be thoroughly surveyed and planned to minimize rock bursts.]

[Also thanks to the use of the latest stress technology. 】

[Plus a large number of safety facilities were laid out in advance. ]

【So during the construction period, no accidents occurred at the Zhongnanshan Tunnel construction site! 】

……

Qin Dynasty.

Ying Zheng was surprised to see that such a huge project had not even had a single construction accident.

I was deeply surprised.

"It's normal that people will die in mega projects."

“But Tianmu said that there were no safety accidents in such a huge project?”

"I guess being a safety officer at a construction site in this future generation must have an easy life, right?"

【For such a long tunnel, and a major traffic artery with so many vehicles passing through, tunnel ventilation is a major problem that must be solved. 】

[To solve this problem, three huge vertical shafts are set up in the tunnel, the largest of which is 661 meters deep! ]

[These shafts are equipped with advanced air exchange systems that work around the clock, effectively extracting vehicle exhaust from the tunnels and injecting fresh air.]

[Therefore, even if you walk through the tunnel, you will hardly notice any unusual smells. The air is fresh and pleasant, and there is almost no difference from the environment outside the tunnel.]

[Ultra-long distance tunnels are an important issue for car drivers and rescue after accidents.]

[To relieve visual fatigue caused by long-term driving, three special light strips with a total length of 450 meters are set up in the tunnel. ]

[Simulate beautiful scenery such as blue sky, white clouds and rainbows to enhance the driver's mood and pleasure. ]

【Coupled with the eye-catching red guide lights, drivers can adapt to the tunnel environment immediately. 】

[Plants are planted next to the light strips, equipped with fill lights to ensure the normal growth of the plants, adding to the ecological beauty of the tunnel. ]

[There are service stations and rest areas in the tunnel, with rockery, pavilions and other landscapes to provide a place for drivers to rest. ]

[In terms of safety, the tunnel is equipped with fire extinguishing equipment every 250 meters and 180 emergency telephones to ensure rapid response in emergency situations. ]

[In addition, there are 52 pedestrian tunnels and 26 vehicle tunnels in the tunnel. ]

【When an accident occurs, there are sufficient escape routes to choose from. 】

[At the same time, more than 10,000 monitoring points monitor the interior of the tunnel in real time. Once an accident occurs, the intelligent system can quickly locate and transmit data to the operation center for processing.]

[After the tunnel was opened, the winding mountain road that originally took 4 hours to travel was now open. ]

【Now it only takes 40 minutes by car. 】

[In addition to transportation, the Qinling Zhongnanshan Tunnel can also play a role in national defense and increase strategic mobility. ]

[After the tunnel was completed, more than 4 vehicles passed through it every day, proving that this tunnel has become another major artery of transportation in southwest my country! ]

Super project, bringing super shock!

When the viewers of the barrage saw the real scenes inside and outside the tunnel, they were filled with emotion.

"I now understand why the University of Tokyo is called the infrastructure maniac."

"A tunnel running through the Qinling Mountains! This is truly a natural barrier turned into a thoroughfare!"

"Brother Tumu is full!"

《Salute to the infrastructure workers! 》

"Will we find the tomb of Little Dragon Girl?"

《18 kilometers of tunnel? Oh my! I don’t even dare to drive in it!》

"I walked past it once. I was the only one in the car in the middle of the night. I was trembling with fear."

"There are so many cameras, I dare not exceed the speed limit..."

"There is a permanent fire brigade in the Zhongnanshan Tunnel."

《This wave is really far ahead! 》

"If the ancients had this tunnel during their Northern Expedition, they could have directly recaptured Chang'an!"
