Chongqing will add another railway passageway to the sea
At 12:33 on October 14, on the Qianjiang Zhangchang railway of joint commissioning and joint test, the harmonious EMU slowly drove into Qianjiang railway station, which indicates that Qianjiang is about to enter the era of EMUs. A 6031 a 6031 Qian Zhang Chang railway connects Chongqing Qianjiang, Enshi, Hubei, Zhangjiajie, Hunan and Changde. It also connects Chengdu Chongqing, Beijing Guangzhou, Zhejiang Jiangxi and other railway trunk lines. Therefore, Chongqing will add another railway access to the sea.
, a large channel to the sea,
"after the completion of the project, it will become a fast passenger and freight channel connecting Sichuan Chongqing region and 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.
nine national invention patents
qianzhou-zhangzhou-changzhou railway is located in Wuling Mountain area. the Apengjiang bridge, a controlled project in Chongqing section, is also known as "the first high-span low-tower cable-stayed bridge of Passenger-Freight co-line express railway 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. Nine national invention patents have been applied for the construction of a 6031 a 6031 bridge, of which the Research Report on cofferdam construction technology of high pier and short tower cable-stayed bridge under complex conditions in mountain valley has passed the appraisal and reached the advanced level in China.
a gold tourism belt "by the end of the year, we can directly take the bullet train to Zhangjiajie and Changsha." Hu Li, a resident of Qianjiang District, is looking forward to travelling by motor car in the future. 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.
