Changes to be brought about by Guizhou Zhangjiakou Railway

Guizhou Zhangchang railway connects Chongqing Qianjiang, Enshi, Hubei, Zhangjiajie, Hunan and Changde, and connects Chengdu Chongqing, Beijing Guangzhou, Zhejiang Jiangxi and other railway trunk lines. Chongqing will add another railway access to the sea.

"after the completion of the project, it will become a fast passenger and freight channel connecting Sichuan and Chongqing with central China, and connecting East China and South China, which will effectively promote the sustained and rapid economic development of Wuling mountain area, promote the construction of inland open Highlands in Chongqing, and strengthen the economic exchanges between the central and western regions." The city's Transportation Bureau said.

at present, there is no direct railway from Chongqing to Zhangjiajie and Changde. Chongqing Changsha railway is connected by Chongqing Huaihua railway and Chongqing Guiyang railway. Chongqing Huaihua railway, a common speed railway with mixed passenger and freight traffic, is also the most important railway channel connecting Chongqing with Changsha Zhuzhou Xiangtan city group in Hunan Province and the southeast coast. A 6031 a 6031 "the Guizhou Zhangchang railway will fill the gap of the railway network in the border areas of Chongqing, Hubei and Hunan." Qianjiang District Transportation Bureau said that after the completion and opening of the railway, it will become the most convenient railway channel from Chongqing to Changsha. Especially after the Chongqing Qianjiang section of Chongqing Hunan high speed railway under construction is opened to traffic, it will be connected with Guizhou Zhangchang and changyichang railways. In the future, Chongqing Changsha railway will be shortened from 5.5 hours now to 3.5 hours. From Chongqing to Xiamen, the current 14.5 hours will be shortened to 8 hours. The

Guizhou Zhangchang railway is located in Wuling mountain area. The Apengjiang bridge, a control project of Chongqing section, is also known as the "low tower cable-stayed bridge of the first high-speed railway crossing passenger and freight lines in China". The a 6031 a 6031 a Pengjiang super major bridge is 1.36 km long and designed as a double track bridge with a main span of 240 meters, of which the main pier is 172 meters high, equivalent to about 60 floors. The whole bridge is composed of short tower cable-stayed bridge, steel structure continuous beam and prestressed concrete tube supported T-beam. Conventional steel sheet pile cofferdams and steel boxed cofferdams cannot be used for the cofferdams of the two main piers (construction enclosures), which brings great difficulty to the construction.

has been proved by experts for many times, and the project construction party innovatively adopts the cofferdam construction method combining the bite pile and the fish belly beam. The cofferdam is not only not easy to seep and leak water, but also solves the problems such as high risk of construction and excavation, poor water stop effect and easy deformation of foundation pit. At the same time, it also improves the operation speed and saves more than one month construction period. A 6031 a 6031 Guizhou Zhangchang railway will be a large channel for poverty alleviation after it is opened to traffic. Wuling mountain area belongs to the old, the young and the poor. With the completion and opening of the Guizhou Zhangchang railway by the end of the year, it will greatly promote the coordinated development of regional economy and society, and promote the poverty alleviation and prosperity of the areas along the line.

at the same time, the railway also links many scenic spots to form a golden tourism belt. Such as Qianjiang Xiaonanhai, Enshi Grand Canyon in Hubei, Zhangjiajie in Hunan, etc. At present, Qianjiang district is speeding up the establishment of Wuling Mountain tourism distribution center, promoting the development and construction of "big tourism economy" in Wuling mountain area, and accelerating the shaping of international tourism city image and brand.
