Speeding southwest - Chengdu Guiyang high speed railway
At 6:58 a.m. on December 16, the first bullet train c6041 from Chengdu east railway station to Guiyang North Railway Station was launched, marking the opening of the whole Chengdu Guiyang high-speed railway, ending the history of no direct railway between Chengdu and Guiyang. (global network)
Chengdu Guiyang high speed railway is an important part of the Lanzhou (Xining) Guangzhou channel of China's "eight vertical and eight horizontal" high speed railway network. The line is connected with Xicheng high speed railway and Chengdu Chongqing high speed railway in Chengdu hub, Guiyang high speed railway and Shanghai Kunming high speed railway in Guiyang hub. Geographically, there is no history of high-speed railway in Yibin, South Sichuan, Zhaotong, North Yunnan and Bijie, West Guizhou. As the first southbound high-speed passenger railway in Sichuan Province, Chengdu Guiyang high-speed railway will be opened to traffic to form a high-speed railway from Sichuan Province to Guangdong, Hong Kong and Macao, and Beibu Gulf Economic Zone, which will improve the level of southbound connectivity, further expand the opening up and promote the development of Sichuan Province Economic and social development is of great significance.
in terms of construction difficulty, Chengdu Guiyang high speed railway runs through the southwest and region of Sichuan, which is closed by mountains, canyons and rivers. Most of the lines are karst terrain, unstable, high gas, high mountain and deep valley, crossing rivers, basins, plateaus, and various topographical and geological problems. From an altitude of 200m to over 2000m, Chengdu Guiyang high speed railway is called "high above the clouds" Iron is a high-speed railway passing through the "Geological Museum".
in terms of ecological protection, Chengdu Guiyang high-speed railway is undoubtedly the pioneer of domestic high-speed railway, reflecting the warmth of human and nature. Due to the special landform and the requirements of environmental protection around the railway, the construction of Chengdu Guiyang high-speed railway is quite difficult. In order to protect the habitat of rare fish and reduce the degree of impact to a lower level, the design of river pier crossing bridge is no longer used in the construction of Chengdu Guiyang high-speed railway. Except for the bridge pier crossing Minjiang River and Jinsha River during the construction period, other bridge piers crossing the river section of Chengdu Guiyang high-speed railway are not involved in the water.
after the Sino Japanese war in Jiawu, the Chinese people really opened their eyes to the world, and finally saw the strategic significance and economic interests of the railway in national defense. After the founding of new China, the Sichuan people, who had just eased from the war of liberation, only took two years to realize the full opening of Chengdu Chongqing railway.
from 0:00 on December 30, 2019, the passenger train adjustment chart will be implemented. Chengdu Guiyang high speed railway will add 39 pairs of daily lines, including Chengdu East to Xiamen north, Changsha south, Shanghai Hongqiao, etc. Chengdu Guiyang high-speed railway will fill the gap between Chengdu and Guiyang high-speed railway, ensure that investment and growth effectively "feed back" to economic restructuring, and play a special role in population flow, exchange and cooperation along the line. This is of great significance to further shorten the space-time distance between southwest and Northwest China and East and South China, to help the region overcome poverty, to speed up the construction of urban agglomerations, and to promote the development of the western region.
