After the new Guiyang Nanning High speed Railway Guiyang Litchi band was put into operation, today (August 31), the Nanning Litchi band was put into operation, and the whole line of the Guiyang Nanning High speed Railway was put into operation. It can be reached within three hours between the two places, making the traffic between Guizhou and Guangxi more convenient.

Crossing Yunnan Guizhou Plateau and Guangxi Basin

Crossing Qingshui River and Hongshui River

From cool Guiyang to green city Nanning

The beautiful scenery along the way waves after waves

It's dizzy

Guinan High speed Railway

It is China's "eight vertical and eight horizontal" high-speed railway network

An important part of the Baotou (Yinchuan) Haikou Channel

The line is led from Longli North Station of Guiyang Railway Terminal

Going south through Qiannan Buyei and Miao Autonomous Prefecture of Guizhou Province

Hechi City, Nanning City, Guangxi Zhuang Autonomous Region

Access to Nanning East Railway Station

The total length of the line is 482km

Design speed 350 km/h

Construction started from the winter of 2016

Full line operation by autumn 2023

The construction of Guiyang Nanning High speed Railway has experienced seven years of wind and rain

Dig holes in mountains and build bridges in water

Across 90000 mountains, high mountains and deep valleys along the way

482km high-speed railway line

Bridge tunnel ratio up to 90%

Behind 107 tunnels and 199 bridges

It's a great project

Enjoy the scenery of the two places through one tunnel

107 tunnels pass through "90000 mountains"

The Longest Tunnel of Guiyang Nanning High speed Railway - 90000 Dashan No.1 Tunnel

Level I high-risk tunnel

No. 4 tunnel of Jiuwan Dashan is under construction

Tunnel 4 is under excavation

Crossing 6 faults and geological contact zones

179 large and small cave cavities were found

What's more, it makes the constructors turn pale

"Carbonaceous shale gently dipping formation"

Workers construct in the No. 4 Tunnel of 90000 Dashan

Great construction difficulty

Risk of operating environment

High requirements

Once known as

Forbidden area for construction of major traffic engineering projects

90000 Dashan Tunnel 4

The mountains are green, not far away

199 bridges span high mountains and deep valleys
