All stations of Chengdu Metro 19 Line

Chengdu metro 19 * * line has a total of 18 stations, all of which are underground stations with a design speed of140km/h. The stations are: Jinxing Station, Huangshi Station, Fifteenth Hospital Station, Fengxihe Station, Wenquan Avenue Station, Mingguang Station, Jiujiang North Station, Longqiao Road Station and Shuangliu Airport 2.

The second phase of 19 line, as the first opening line of the fourth phase construction plan of Chengdu urban rail transit, starts from Jiujiang North Station (excluding) in the west and ends at Hejiang Station (reserved) in the east. It connects with 18 line via Tianfu Station, runs to Tianfu Airport North Station, and connects Wenjiang District, Shuangliu District and Tianfu New District in series, which has the composite function of urban express line and airport line.

The second phase of 19 line has a total length of 43. 17km, and 4A/8A grouping and mixed lines will be realized in the * * line section. After the initial operation, it will be connected with 19 line, with the total length exceeding 100km, which will effectively enhance the regional radiation belt power, give full play to the service function of rapid traffic communication after rail transit networking, and close two airports.

Introduction of main works of Chengdu Metro 19 Line;

The second phase project of Chengdu Metro 19 line passes through complex and diverse strata, including low gas stratum, water-rich sandy pebble stratum, sandy pebble stratum, mudstone and lenticular sand composite stratum. Shield tunneling will cross the airport apron, railways, existing subway lines, highways, rivers and dense buildings.

During the shield crossing the risk source, the project will follow up the shield tunneling information in real time; Combined with the situation of shield passing through different areas, special construction control measures such as "opening in soft stratum, opening under pressure in high permeability sandy pebble stratum" and "grouting in middle shield+synchronous thickening double slurry+grouting behind segment wall+grouting in four holes of segment" are formulated. Through multi-process and whole-process control, the strata are grouted in time during shield tunneling, which provides a guarantee for the safe and efficient completion of shield tunneling tasks.
