Let Chongqing Wulong "Steel Armor Mountain"

It attracted people's attention

This strange mountain

It is a little-known "super project"

The reason why it is called "Gangjia Mountain"

Because this mountain is really

Wearing steel armor

This steel armor holds 20,000 tons of rock

Nailed on the mountain

Behind this is

A shocking and touching story

2017

Chengdu Railway Bureau staff took aerial photos

I found a crack in the mountain.

It has a width of 67 meters and a height of 63 meters.

Dangerous rock mass weighing up to 20,000 tons

A serious threat to the mountain below

The Chongqing-Huaihua Railway Line in operation

After numerous studies and demonstrations

They finally found a

The best solution full of imagination and challenges——

Laying active networks in the mountains

Nailing the dangerous rock into the mountain

"Drill a mortise hole horizontally

Put the mortise in.

Use mortise ropes to nail the dangerous rock to the mountain behind.

This difficulty coefficient

In the mountains

"Flying over the eaves and walls" and "threading the needle"

After two years of unremitting efforts

They finally succeeded in putting "armor" on the mountain

This project also achieved two "world firsts"

First, the vertical scaffolding height

Second, the world's first "in-situ reinforcement"

Behind the miracle

It is the silent persistence of countless ordinary forces.

It is also a relay inheritance of mission and responsibility

After the completion of Gangjia Mountain, long-term maintenance is required.

Staff of Chengdu Railway Bureau

Regular maintenance inspections will be carried out

Day after day of hard work

Ensuring the safe operation of railway lines

Three hundred and sixty-five days a year

They mostly work outdoors.

Climb the mountain every day to check different points

I didn't have time to go down the mountain for lunch at noon.

They bring their own dry food

Sit on the ground, "roadside picnic"

Behind is work, in front is scenery

"The more magnificent the scenery is, the greater the pressure behind it is"

They laughed and said

"We, several generations, will protect it for a lifetime"

In ancient times, there was a story about Yugong moving mountains.

Today, people are wearing steel armor for the mountains

Seemingly different logical directions

But they have similar wisdom and spirit

People see the story behind this super project

Many people left messages expressing their feelings

"There are always people trying their best to protect the peaceful years! Salute"

“There are always people who carry the burden for us!”

…

Life restricted area builds the road of life

Across mountains and seas

Looking to the west of the motherland

A railway

With the eager anticipation of the people in Xinjiang and Tibet

Full line open to traffic

——Geku Railway

December 9, 2020

The Xinjiang section of the Geku Railway (Mangya Town-Korla) was opened to traffic

Realized the capital of two adjacent giant frontier regions

Urumqi and Lhasa

Shortest direct rail connection

The total length of the Golmud-Korla Railway is about 1,200 kilometers.

In Golmud, the Qinghai-Tibet Railway

The Golmud River line connected to the

Along the northern foothills of Kunlun Mountains

Traveling westward along the southern edge of the Qaidam Basin

Climbing west

And cross the Altun Mountains at an altitude of more than 3,000 meters

Then descend to the foot of the mountain at an altitude of more than 800 meters

Arriving in Korla, Tarim Basin

Building this road through western China

The railway project between the two provinces is not an easy task

Gobi winds are also a challenge

Especially in Ruoqiang area, the sandstorm is serious.

After all, this place is located on the edge of the Taklimakan Desert.

The Geku Railway has become a major railway construction project in China.

One of the railways with the most severe sandstorms

In addition, along the Geku Railway

The maximum elevation difference of the terrain is 2500 meters

To reduce the slope

The whole journey requires crossing bridges and passing through tunnels

Walking through the rolling mountains

It is one of the railways with the largest height difference built at one time in my country.

The control engineering of Geku Railway is indispensable

As the longest bridge on the line

It is also the span of Xinjiang

The longest railway bridge

——Taitema Lake Bridge

To protect the local ecological environment

From south to north across Taitema Lake

(The tail lake of the Tarim River)

Total length: 24.558 km

The largest controlling project in Qinghai section

The Gedong Bridge is undergoing rotation and closure construction

The Golmud-Korla Railway is built to cross the Altun Mountains.

Many tunnels were built

The first tunnel in Xinjiang

It is Tunnel No. 1 of the Yitongbulak Tunnel Group.

This group of tunnels

It's just an appetizer for crossing the Altun Mountains

As China's first step

The Altun Mountains, the boundary between the second terrace and

Like a natural chasm

I want to go through it completely

Or we still have to rely on our country's first

Crossing the middle of the mountain range

It is 13.195 kilometers long.

It is the longest tunnel on the entire line.

It is also the only Class I risk tunnel.

It is also the last tunnel to be completed.

Altyn Mountains

Between 3000m and 3600m above sea level

Located in the cold climate zone of the Qinghai-Tibet Plateau

Desert, no-man's land, drought and little rain

The temperature difference between the four seasons is large, and the winter is long and cold

Average annual temperature: 2.5℃

In extreme cases -37℃

Its geological conditions are extremely complex

The Altun Mountain Tunnel will cross 11 fault zones

Severe fault fragmentation

Among them, there are 9 water-rich areas

Large amount of water outflow in the tunnel

The maximum daily water output is 27,000 cubic meters

Equivalent to the water storage capacity of 10 standard swimming pools

Builders often work in the rain

Building bridges, drilling mountains, paving roads

They are in the forbidden zone of life

Laying a railway that carries life

Behind the rapid flow of people between the two places

A group of people overcame

Harsh natural conditions

Harsh working environment

A construction miracle achieved

It is a well-deserved "super project"

Not afraid of difficulties, forge ahead despite challenges

Descendants succeed each other, hard work

These are passed down in our blood.

National Spirit

In every ordinary and great individual
