I! Pretending to Be Reborn, Director of Doomsday Hoax

But the Sichuan-Zangzhou Railway has to pass through this snow-covered plateau...

This has become a unique engineering miracle in the history of world engineering.

Before that, there was the Canton Bridge in the Canton area, known as one of the New Seven Wonders of the World.

There is also the Qinghai-Tibet Railway, which is known as the four major projects of the new century in Longguo and has been selected into the list of century-old projects in the world.

Farther away, there is the Chuanyun Railway, which symbolizes the three miracles of human beings conquering nature in the [-]th century, and topped the list of the three miracles!

However, as soon as the Sichuan-Zangzhou Railway came out, it was all over, and all engineering legends have since become a thing of the past!

This railway, its terrain and weather conditions are difficult, majestic and unprecedented, which is enough to make many great projects in the world stand still!

Even the world-renowned project that symbolizes the unity of Ouzhou, the Shenggeda Baseline Tunnel with a total length of 57 kilometers, is far behind!

Back then, Qu Huamei and his wife, who led the railway team and followed Longguo's orders to build railways everywhere and pass through the frontier fortress, received an order to open up the Sichuan-Zangzhou Railway.

And this is an almost impossible task.

Because the Sichuan-Zangzhou Railway will pass through the most majestic mountain range in the world, the Hengduan Mountains, the dangerous foothills that have been majestic for thousands of years and capture the ultimate scenery in the world!

Qu Huamei said proudly: "I think back then, my husband and I took over the arduous task of Longguo without any hesitation!"

"Director Xu, do you know the Hengduan Mountains? Sixty-five million years ago, a meteorite the size of Mount Everest hit the blue star, the crust was activated, volcanoes erupted, and dinosaurs became extinct..."

"The Tianzhu plate engulfs the Tianzhu continent, across the Wangyang sea, and subducts toward the Eurasian plate."

"The huge impact force and the terrifying crustal movement caused Wang Yang to close, and the Qingzang Plateau bulged up, overlooking the whole world!"

"However, the uplift of the Qingzang Plateau still hasn't stopped. All the way to the north, it finally encountered the obstruction of the Yangtze Plate in the ancient continent of Longguo, and stopped abruptly..."

"At that moment, the mountains and rivers changed direction, and the Hengduan Mountains were born. It is vast and magnificent, with 35 square kilometers of undulating and endless stretches!!"

Qu Huamei wiped away her tears.

Although she is now the dean of the Northwest Railway First Academy, when she was young, she and her husband came all the way from the southwest to build roads.

In the end, because of overwork, her husband died honorably for the country in front of the Brahmaputra Bridge.

Qu Huamei originally thought that she would never see Chuanzang continue to build the railway again in her whole life.

Her dream is actually to walk the same road back then and see where she and her husband came from.

Who would have imagined that since the current extremely cold railway passes through the old line of the Sichuan-Zang Railway, a brand new extremely cold line will be built on this railway! !

Quhua Meimo held the Yage Zangbo River on the map, and asked: "Director Xu, the old woman begs for orders, and give me the extremely cold route in Sichuan and Tibet... the old woman conquered Hengduan in the first half of her life. The mountains, in the last few decades, vowed to conquer this problem again!!"

Xu Qiu was deep in thought.

Of course he knew what old man Qu Huamei was thinking.

However, the Hengduan Mountains, covering an area of ​​35 square kilometers, are so towering that they touch the sky.

The Sichuan-Tibet line needs to run through the Hengduan Mountains, cross the impact zone of the Blue Star plate, and go west all the way to the hinterland of the Qingzang Plateau.

On the way, earthquakes, landslides, rockbursts, karsts, underground rivers, debris flows, unstable rock piles, fault fracture zones, high-temperature rock heat, high ground stress, and other adverse geological hazards abound.

The geology is not only complicated, but also as dangerous as a fault breaker. With the expansion of the Qinghai-Tibet Plateau to the north, it is just around the corner, like the sword of Damocles, hanging over the heads of construction workers and railway personnel, and cutting it off at any time! Walking through such a plate fault zone, Just like a person walking on the frozen river that wants to thaw, the road is full of dangers...

Qu Huamei is old and unable to keep up with mental and physical difficulties. Can she really take on such a heavy responsibility?

What's more, the section from Luding to Mount Zhedo that Xu Qiu hadn't solved before is exactly one section of the Chuanzang line!

It can even be said that the laying of the extremely cold line in Chuanzang is more dangerous and difficult than the Qingzang Plateau and Linzhi Ya'an section!

Xu Qiu glanced at Qu Huamei, the latter's old eyes were full of pleading, but there was an extremely strong belief.

That is the great belief that man can conquer nature since the ancestors of the Dragon Kingdom! !

At this moment, Xu Qiu was shocked, moved in his heart, and made a decision.

He turned to face the entire conference room, and said in a loud voice: "From now on, I will appoint Dean Qu Hua Mei Qu as the person in charge of the Longguo Extreme Cold Line-Yichuan Zang Branch Line!!"

"it is good! !"

"Today we will break through the Hengduan Mountains again! Don't be afraid of natural dangers, serve the country and the people, strong people of the Dragon Kingdom!!"

An Yongjia, director of the General Administration of Railways, and the deans of eleven other railway design institutes across the country stood up and made passionate remarks in unison, saying:

"Director Xu, Dragon Kingdom will never be defeated by difficulties! Please assign us a difficult railway!!"

"I will wait for Director Xu to share his worries!"

"Please rest assured Director Xu, please rest assured the people, please rest assured Long Guo!!"

The people of Longguo Engineering actively applied for tasks and wanted to serve the country.

This scene moved everyone present.

If there is no such people, how can the Dragon Kingdom be strong?

Or to put it another way, the reason why the Dragon Kingdom is so powerful is precisely because of such people! !

"Xu Qiu, on behalf of the people of the Dragon Kingdom, thank you seniors!"

On the stage, Xu Qiu respectfully woke up with an ancient ceremony.Express great respect.

"In this case, I will assign the responsible section of the extremely cold route to you.〃

"Due to the construction process, there are still many difficulties to be overcome."

"And, this is a railway that runs through the country, and part of the extremely cold line even needs to demolish urban buildings and pass through the city."

"Currently, we still need to retain the current railway transportation to transport materials to various places."

"Therefore, there are now two laying directions."

"The first is the construction of railways in difficult areas. For example, the Qingzang Plateau section, the Ya'an-Linzhi section, Yichang-Wanzhou, and Luding and Zhedo Mountains."

"I'll give you three months. If you can't overcome it within three months, then this section of the road will be re-planned, bypassing this restricted railway area, and go a long way to ensure the continuity of the national railway!" "Second, is Start building from no man's land."

"It will gradually involve villages, towns, and cities without railway areas, and finally, start construction in the original railway area. This is also the last step of the extremely cold railway."

In the territory of Longguo, the railway network is already quite complicated.

At this moment, railway transportation is still the main way of replenishing materials in various underground cities, and it is impossible to dismantle it because of the construction of the extremely cold line.

Wait until all the other railroads have been built, and then make up this area at the end.

But there is also good news. Since the nuclear-powered dragon is too large, the width of the steel rails it needs will be quite amazing.

Therefore, workers can build the outer extreme cold railway without dismantling the ordinary railway in the middle, and continue the railway transportation.

Until the lines across the country are connected together, the ordinary railways will be dismantled and completely opened to traffic!

To a certain extent, this can ensure that the national railway transportation will not be affected by the laying of extremely cold lines.

Qu Huamei, An Yongjia and the others saluted respectfully, and said: "I will take orders, and the extremely cold line of the Dragon Kingdom will be handed over to us. Please rest assured Director Xu and the country!!"

Xu Qiu nodded and said no more.

He set his sights on Wo Chengwen and the others.

The extremely cold rail was born from the hands of this group of older rail engineers.

"How is the research progress of rail laying construction technology?"

Wo Chengwen glanced at He Yude. Among the people present, He Yude was the oldest.

The old man smiled slightly, and gave up the opportunity to speak to Wo Chengwen, a young man in his 60s.

Wo Chengwen got up, with a respectful expression, like a pilgrimage, and said: "Director Xu, under your guidance, we have successfully developed the extremely cold steel rail yesterday afternoon!"

"And now, our entire team is trying to find a way to weld the rails..."

"At present, some preliminary results have been obtained!"

"Although the seamed rails can minimize the difficulty of welding, this is a reversal of history. We cannot bring back the seamed rails that have been eliminated long ago!"

"Therefore, the solution we finally chose is to create seamless arctic steel rails!"

Xu Qiu nodded.

Seamed rails refer to the cracks between the rails.

A track that is hundreds of kilometers long must be spliced ​​​​by steel rails of smaller length.

In the previous seamed track, there were joint splints and joint bolts between the two rails, and there was a rail joint a few millimeters long in the middle.

The seamless railway removes the rail gaps of several millimeters, and the entire rail looks like a natural one.

He said: "In the era of extreme cold, once a crack occurs in the rail, the airtightness of the entire rail will be destroyed."

"Once the cold air gets into the gap and condenses into ice, the rails will be stretched apart and damaged."

"Seamless rails are the only option."

"No matter how difficult it is, the extremely cold seamless steel rail must be welded!"

Wo Chengwen bowed, "Director Xu is right!"

"The way we weld seamless rails is to improve the process of rail laying!"

The craft of rail laying construction?

Everyone was puzzled, even Xu Qiu frowned, wanting to see what Wo Chengwen and others thought.

0.. ask for flowers...

Wo Chengwen went on to say:

"According to the general rail laying construction process, we first need to place sleepers and lay tool rails."

"The pendulum sleepers are lifted and transported manually, distributed evenly according to the designed quantity, and a positioning sleeper is placed every 25 meters, and then the method of manual lifting is adopted to align the center of the sleeper with the center line of the road and make the sleeper perpendicular to the center line of the road. "

"After completing these steps, pull the hemp rope on the end of the positioning sleeper, and use a crowbar to straighten and place the rest of the sleepers according to the distance between the sleepers."

"And then comes our critical step, laying the tool rails!"

"This is also the focus of our process improvement!"

"According to the original method, the workers need to manually lift the self-made rail lifting pliers into the supporting rail groove, and then make the connection."

"During this process, workers need to mark the inner side of the rail waist with white paint at the sleeper position, mark the curved section on the inner side of the outer rail waist, and use a square ruler to position the other side,"

"Wait until the rail fasteners on one side are tightened, and then use the gauge ruler to slowly adjust the position of the other rail according to the prescribed rules."

"And we plan to carry out stress relief and rail temperature locking in advance before laying tool rails!"
