Coordinates China ｜ How to cross Tianshan

Xiaoxin said

In the past ten years, a series of heavy weapons and super engineering created by central enterprises have engraved new coordinates of national development from different dimensions. On September 12th, the online theme promotion of "our ten years@coordinates China" was officially launched. Over the major achievements of representative infrastructure construction and scientific and technological innovation, it shows the courage, courage and wisdom of challenging the limits and challenging the limit.

The total length of the Wawei Highway is 318.5 kilometers, of which about 22.1 kilometers of Tianshan Shengli Tunnel is the control project of the entire line and the longest highway tunnel in the world under construction. After the completion of the highway, Urumqi to Korla to Korla is shortened by about 200 kilometers compared with the status quo, and the drive will be shortened from more than 7 hours to about 3 hours. Today, Xiaoxin brings you the first issue of the "coordinate China" series theme film, and China's span "Cross Tianshan".

One mountain crossing the boundary north and south

Vanci -psionic plus desert

Plateau Snow Mountain, difficult and beautiful

Tianshan Mountains, which runs through the east and west of Xinjiang

Since ancient times, people have been referred to as people.

Just in this height that people's eyes are difficult to reach

A leap that "runs through Tianshan" is happening

Tianshan Shengli Tunnel Cave Entge 2800 meters above sea level

It is the "throat" project of Wuwei Highway

It is also the world's longest highway tunnel under construction

The total length of the tunnel is 22.1 kilometers

The sum of five Nanjing Yangtze River Bridge

The Wuwei Highway where it is located

Almost parallel to "China's Most Beautiful Highway" Duku Highway

Their ultimate purpose

It's all crossing the Mangshan Mountains

Part1

Why cross Tianshan?

Tianshan stretches for about 1760 kilometers in our country

Average width of 300 kilometers

It looks like a thick book

Divide Xinjiang into southern and northern Xinjiang

For the core area of ​​the Xinjiang Silk Road Economic Belt

It is especially important to get through the "barrier" of transportation

In the 1970s

We finally opened up the Great Tianshan Traffic Artelle

Solo highway

However

This secondary road is only open for five months a year

With the in -depth advancement of the "Belt and Road" construction

Xinjiang west leading east, east all over the west

The location advantage is even more highlighted to "go" over Tianshan and "climb" through Tianshan

It's far from meeting the needs of the economic needs

Decade

Highway projects that cross Tianshan have been implemented one after another

Never break through the limit

The builders built along Tianshan

Baha Road on the East Line

The Wuwei high speed of the midline is under construction

The Duku Expressway of the West Line is also in the preparation of Li Bingzhima

They will all cross Tianshan

Become a road of happiness that runs through north and south

Part2

How difficult is it?

It is not easy to repair the tunnel on the Tianshan Mountains

The builder must not only overcome

The construction environment of high cold, hypoxy oxygen

Also through 16 broken belts

There are risks such as rock explosion, large deformation of soft rocks, and rough water.

Spanning Tianshan

In addition to relying on builders

The unyielding spirit of courage to fight against heaven

It is also relying on the development of the motherland and increasingly strong

March 2020

From Urumqi in the north, from the south to Weili County

Wuwei Highway officially started construction

Arrived to Mang Ran Tianshan

Use wisdom and sweat to penetrate the mountains

Construction of the Tianshan Shengli Tunnel

If the construction plan of the previous oblique well assistance

The construction period will be as long as 72 months

To solve the problem of long construction period

The builders proposed the world's first creation

"Three Caves+Four Vertical Wells" construction plan

"Three Caves+Four Vertical Wells" construction plan

"Three Caves" is to add a medium -guided hole in the middle of the traditional tunnel to assist the work to shorten the entire tunnel to shorten the construction period.

The "Tianshan" and "Shengli" TBM (full cross -section hard rock tunnel excavator), which is responsible for this heavy responsibility, is developed by my country's independent innovation and "tailor -made" giant "open road pioneer" for Tianshan Shengli Tunnel. A well -deserved major country.

The "Four Ending wells" is a ventilated vertical well, with a maximum depth of 702 meters. This height is 80 meters higher than the highest building in China -Shanghai Central Building. "Respiratory system".

In the end, the builders will take the tunnel effective construction period

Control in 52 months

Fill the gap of the domestic ultra -long tunnel construction technology

Become the iconic results of my country's highway construction field

Part3

Why can it cross Tianshan?

Realize the feat of crossing Tianshan

Can't do without the spiritual inheritance of a generation of central enterprise builders

They are in a thorns and bravely break through no one

Use your feet to measure the land of the motherland

They open the way every time they use solid footsteps

Completed the great leap again again

Inherit, inherit, carry forward, and continue to write

State -owned enterprise spirit in the new era

In the past ten years,

The "sky roads" that span the mountains, the river, and the sea one by one

Like a dragon that is empty

Connect the people of the whole country closely

Take us to the common dream and future

at the same time

It is also written with a grand episode that belongs to the new era

Do you want to know which new era coordinates?

The comment area tells us ~

Please continue to pay attention to "coordinate China",

The next issue is equally wonderful!

The next preview

September 14th

The second issue of the theme film of "Coordinates China" series

China's "Crossing the Sea" will be launched

Stay tuned!
