Weigh! Construction of Yunnan section of Chongqing Kunming High Speed Railway starts

On December 20, the construction of Yunnan section of Chongqing Kunming high speed railway, an important part of the "eight vertical and eight horizontal" high speed railway network and Beijing Kunming high speed railway channel, was officially started. After completion, Kunming to Chongqing and Chengdu will be compressed from 5 to 6 hours to 2 hours. A 6031 a 6031 Chen Hao, Secretary of the provincial Party committee and director of the Standing Committee of the provincial people's Congress, announced the mobilization order for the construction of Yunnan section of Chongqing Kunming high speed railway, Ruan Chengfa, deputy secretary of the provincial Party committee and governor, Li Jiang, chairman of the provincial CPPCC, Wang Tongjun, deputy general manager of China Railway Group, Liu Huiyan, member of the Standing Committee of the provincial Party committee and Secretary General of the provincial Party committee, Duanqi, executive deputy director of the Standing Committee of the provincial people's Congress, and Zhang Rongming, member of the Party group of the provincial CPPCC, attended the ceremony Type. The commencement ceremony was presided over by Wang Xiangang, vice governor. A 6031 a 6031 extended reading: a 6031 a 6031 Beijing Kunming high speed railway, a 6031 a 6031 Chongqing Kunming high speed railway is an important project of the national medium and long term and 13th five year plan railway network planning, and also a national key project of "one hundred transportation poverty alleviation projects". It is led from Chongqing West Railway Station, and passes through Chongqing, Sichuan, Guizhou and Yunnan provinces and cities. The total length of the line is 69 9 km, design speed of 350 km / h, total investment of 141.62 billion yuan, including 388.6 km of Yunnan section, accounting for 56% of the whole line, passing through Zhaotong City and Qujing City of Yunnan Province, and finally arriving at South Kunming station, with 11 stations in total. After connecting with the national road network, it will form a backbone channel between Yunnan, northwest, North China and other places, which can directly reach Beijing, Tianjin and Hebei, forming another fast railway channel from Beijing to Kunming. The difficulty of the construction of

should not be underestimated: the

Chongqing Kunming High Speed Railway climbed from Sichuan basin to Yunnan Guizhou Plateau, with huge topographic relief, complex geological structure, overlapping peaks, deep river valley, karst development, fragile ecology, extremely difficult engineering conditions and tight schedule. There are 107 bridges, 53 tunnels and 87.4% of bridges and tunnels in Yunnan section. It is necessary to overcome the difficulty of three times altitude difference between Sichuan Basin and Yunnan Guizhou Plateau. Yiliang tunnel, the longest high-speed railway tunnel in China, with a total length of 24.3km, and Zhaotong tunnel with a Karst Section of 10km and a total length of 16.3km are to be opened. Luoze River Bridge with a height of 200m is to be built to overcome the tunnel and station crossing Kunming Changshui country The construction period of the International Airport is expected to be 6 years. The new engine of the development of

urban agglomeration & nbsp; & nbsp;

Chongqing Kunming high speed railway is located in the core of the western development. In the north is the Chengdu Chongqing urban agglomeration with Chongqing and Chengdu as the "dual cores"; in the south is the central Yunnan urban agglomeration with Kunming as the center, including Qujing and Yuxi. It is of great significance to strengthen the connection between Chengdu Chongqing and the central Yunnan Urban Agglomeration, strengthen the effective integration of the three free trade pilot areas of Yunnan, Sichuan and Chongqing, promote the economic and social development along the line, tackle poverty and promote the progress of national unity. To serve the great support of national strategy. Chongqing Kunming high speed railway connects Chongqing, the upstream hub of the Yangtze River Economic Belt in the north, enters the economic corridor of the new Eurasian Continental Bridge through Xi'an; connects Kunming, the radiation center facing south Asia and Southeast Asia in China in the south, radiates the Bangladesh China Myanmar India Economic Corridor relying on Kunming; and borders the Yangtze River Economic Belt in the East. When Chongqing Kunming high speed railway is launched and Fuxing is flying close to the ground, the location advantages of Chongqing and Kunming will be more prominent, which will provide strong transportation support for the construction of the "belt and road" and the development of the Yangtze River economic belt by actively serving the western provinces and integrating them into the national development strategy.
