Characteristics of Cheng Kun's Double Track System

In order to ensure the smooth construction of Cheng Kun double-track project on schedule, the construction unit has overcome the difficulties of narrow construction site, large height difference and wide aerial work area. In view of the complex geological conditions in the site and the harsh weather in the western Sichuan Plateau, the construction process control and personnel management were strengthened, and a number of new construction technologies were adopted to properly solve various problems encountered in the construction.

Chengdu-kunming railway's capacity expansion and reconstruction project includes six passenger stations in Shawan South, Ebian South, Jinkou Henan, Ganluonan, Yuexi and Xidexi, and five crossing stations in Yangang, Fandianzi, Kete, Mantan and Luo 'an, as well as related production and living houses. After the completion of the main structure, it will enter the sprint stage of beam erection and track laying. The outline of the station building of Jinkouhe South Station is designed with local towering valley elements, and the architectural color is refined from the local Yi traditional costumes, highlighting the regional culture.

Chengdu-kunming railway double-track railway is a new or additional second-line railway based on the existing chengdu-kunming railway, with a total length of more than 800 kilometers, which is constructed and opened in sections. At present, only the Emei-Mianning section is still under construction and is scheduled to open to traffic in 2022. By then, chengdu-kunming railway double track will be separated from old chengdu-kunming railway, which will greatly improve the passenger and freight transport capacity of the railways in southwest China.
