The steel bridge project of Chengdu Rail Transit Line 19 was successfully opened to traffic

The steel bridge for the upramp of the Airport Expressway at Shuangliu Airport Station in the Civil Engineering Zone 2 of the second phase of Chengdu Rail Transit Line 19, which was constructed by Suitong, has successfully completed various testing experiments, passed the acceptance of the project department, the supervisor and the airport, and was successfully opened to traffic.

The second phase project of Chengdu Rail Transit Line 19 is located in Shuangliu District, Wuhou District and Tianfu New District of Chengdu. The project starts from Jiujiang North Station (not included) of the first phase project and ends at Hejiang Station, Dongshan Avenue, Tianfu New District (reserved ). The line is mainly laid from northwest to southeast along Qianzimen Road, Xihangang Avenue, Shuanghua Road, Luojia Datang Protective Green Space, Xinquan Street, Ningbo Road and Dongshan Avenue. The total length of the line is about 43.17km, all of which are underground lines. There are 12 underground stations in total, including 1 reserved station (Hejiang Station) and 10 transfer stations. The maximum station spacing is 5.389km (Xihangang Passenger Transport Center Station ~ Wenjiashan Road Station), the minimum station spacing is 1.457km (Wenjiashan Road Station ~ Muhua Road Station), and the average station spacing is 3.578km.

The construction site of the steel bridge is located at Chengdu Shuangliu International Airport and is a key node project of Chengdu Line 19. Compared with ordinary projects, the bridge has high technical requirements and complex construction difficulties. In view of the special conditions on site, our company coordinated and actively organized to overcome various difficulties encountered during construction and successfully completed the delivery. On the occasion of the delivery and opening to traffic, I would like to express my sincere thanks again to the leaders at all levels of the Seventh Hydropower Bureau for their understanding, cooperation and support of our on-site work.
