Customer Cooperation Case

The Changyi Changsha high-speed railway is located in the northwest of Hunan Province, China'An important component of the "Eight Verticals and Eight Horizontals" high-speed railway network, with a total length of the line157.502Kilometers, with a bridge tunnel ratio of83.94%The entire line includes Changde, Hanshou South, Yiyang South, Ningxiang West, and Changsha West5A station with a designed operating speed of per hour350Kilometers.

The Changyi Changsha high-speed railway is an important component of the Chongqing Xiamen high-speed railway corridor, and will work together with railways such as Chongqing Guizhou, Guizhou Zhangchang, and Changgan to build a major passenger transportation corridor between Sichuan Chongqing and Hunan Jiangxi Fujian regions. Among them, the Changyi Changsha RailwayCYCZ0-1The main works of the section include:subgrade2.576km/2Location, Bridge17.934km/1Seat, steel structure engineering includes32+90+90+32A steel box girder with a height of meters66High height steel box arches and ancillary structures, spanning over existing railway lines on the bridge-Shichang Railway.

Longshengda, Hunan(Sheng Shida)Signed a supply contract with Changde Xinchuang for the projectCYCZ0-1Supply spiral steel pipes for the section. In bridge pile driving engineering, spiral steel pipes can be used as head support piles and lining. When making supports, the spiral steel pipes are welded together with steel plates to form a stable support structure that can effectively withstand the weight and pressure of the bridge,After the completion and opening of the Changyi Changsha Railway, Hunan Province will truly achieve14The goal of connecting all cities and prefectures to high-speed rail will further transform Hunan Province's geographical advantages into road network advantages, which will promote Hunan's external exchanges and cooperation, and enhance our province's key position as a central node for north-south exchanges in the Yangtze River Economic Belt and the Yangtze River Midstream Urban Agglomeration.
