The first double line electrified railway in the south of Shaanxi Province opened successfully

Yangpingguan Ankang Railway additional second line project (Yangan second line), which was designed by China Railway First Survey and Design Institute, was successfully put into operation on 27th, which is the first double line electrified railway running through the south of Shaanxi. The construction of

Yangan second line started in July 2015, with a total length of 329.51km and 30 stations. The line is adjacent to Qinling Mountain in the north and Dabashan Mountain in the south, with twists and turns. The proportion of bridge and tunnel projects is 45%. There are 176 bridges with a total length of 45.01 km, accounting for 13.65% of the line length. There are 72 tunnels with a total length of 103.583 km. The

Yangan second line passes through Qinba mountain area and Hanzhong Basin. The geological structure along the line is complex and there are many unfavorable geology and special geotechnical distribution. The new line and the existing line in operation are side by side and frequently changed. At the same time, the line crosses Beijing Kunming Expressway with high technical requirements for construction and Bridge transformation. Under the condition of normal operation, the station building reconstruction project needs to be disconnected Same as standard catenary, signal, communication equipment, etc. The

Yangan second line is distributed along both sides of Jialing River and Hanjiang River, passing through the habitat and water source of national first-class rare bird zhuq. The impact of construction and operation on water source, water quality, environment and noise needs to be controlled. The design team ensures that the water quality and water body meet the standards and minimize the impact of the project on the habitat of Hanjiang River and zhuq River by optimizing the route selection, adding rainwater treatment system, noise control and dust prevention, wrong time construction, full-time personnel training and other means. Located in the intersection of Sichuan, Shaanxi, Hubei and Chongqing, the

Yangan line is located in the geometric center of Guanzhong, Chengdu Chongqing and Hanjiang Economic Zones. The opening operation of Yangan second line solves the problem of insufficient transportation capacity of Baocheng railway, which is of great significance to give full play to the overall benefits of the Southwest Road Network and improve the transportation capacity of Southwest China.
