The Jiangsu section of the high -speed rail along the north, start!

Yangtze Evening News, September 28 (Reporter Shi Xiaolei) On the morning of September 28, the Jiangsu section of the Shanghai -Chongqing high -speed rail (north along the river) was simultaneously started in Nanjing, Yangzhou, Taizhou, Nantong, and Suzhou.

This is a long -awaited high -speed railway. As early as 2016, the "Medium and Long -term Railway Network Plan" issued by many national ministries and commissions proposed a high -speed railway network with the main channel of the "eight vertical and eight horizontal" main channels, the connection between the regional connection line, and the intercity railway supplement. The high -speed railway along the river is one of the main channels of my country's "eight vertical and eight horizontal" high -speed rail network. In 2018, the State Office of the Leading Group for the Development of the Yangtze River Economic Belt and issued the "Implementation Plan for Promoting the Construction of the Yangtze Economic Belt along the Yangtze High -speed Railway Channel", which clearly proposed to form a high -quality and high -quality high -speed railway channel along the river as soon as possible.

The Shanghai -Chongqing high -speed railway is more than 2,000 kilometers. It passes through key cities such as Chengdu, Chongqing, Yichang, Jingmen, Wuhan, Hefei, Nanjing, Nantong, Shanghai and other key cities. my country's most developed vitality and potential areas are also the main ecological corridors. It can be said that the Shanghai -Chongjiang high -speed rail along the river as a major iconic project that supports the development of the Yangtze River Economic Belt is the main road of passenger transportation along the country's "eight vertical eight horizontal" channel and the high -speed railway network "gold belt" that takes into account the multi -road network function. It is also the backbone ecological engineering of the golden transportation artery and the comprehensive three -dimensional traffic corridor of the Yangtze River Economic Belt that promotes the coordinated development of the East, Central and Western regional economic and social.

The North River high -speed rail (Shanghai to Nanjing to Hefei section) is an important part of the Shanghai -Chongqing high -speed rail. The design speed is 350 kilometers per hour, and the main line operation length is 553.8 kilometers. House) 116.40 billion yuan. The Jiangsu section is from east to west.

It is worth noting that the northern river high -speed rail crosses the river between Taicang Taicang and Nantong in Suzhou, using the "South Tunnel North Bridge" design plan. Among them, the Chongtai Yangtze River Tunnel in the south section has a high standards, a large construction standard, a large scale, a long distance of shields, a high technical difficulty, and a high risk of construction safety. The target of the tunnel design is 350 kilometers per hour, and the total length is 14.25 kilometers. It is the high -speed railway across railway Tunnel project with the highest construction standards in my country, the longest -distance excavation distance and the largest engineering scale. In the northern section of the Chongqi Yangtze River Gong Railway Bridge, the main bridge adopts the main cross -400 -meter steel truffle binding to the Liang Wuyan orbit cable bridge.

The Jiangsu section of the north along the Yangtze River is the main channel of the eastern section of the high -speed rail channel along the river, filling the gap in the high -speed rail of the north bank of the Yangtze River in Jiangsu. Among them, the Shanghai to Nantong section is the composition of the Beijing -Shanghai channel and the coastal passage. —The important part of the main axis of the "Z" of Shanghai -Nanjinghe and Shanghai -Hangzhou -Hangzhou -Ning Dynasty, it plays an important role in supporting the integrated development of the Yangtze River Delta. Its construction is conducive to the connection between the Yangtze River urban groups to further closely connects with Shanghai, Wuhan, Chongqing, Chengdu and other large cities. It is of great significance.
