Chengdu Metro Line 10 shield machine "excavates" directly to Shuangliu Airport

China Construction machinery information

phase I project of line 10 is about 10.9 kilometers long, with a total of 6 stations, including taipingyuan station, Chujin station, Huaxing station, Jinhua station, airport station 1 and airport station 2

after the completion of this line, citizens can take the subway from the central urban area of Chengdu to Shuangliu International Airport directly, realizing "zero transfer" between air transportation and subway transportation

at present, the South extension line of Metro Line 1 has entered the stage of no-load trial operation, and will be put into trial operation as soon as July this year. The line starts from Century City station and ends at Huayang station

on April 30, at the "launching ceremony of the first shield machine of Chengdu Metro Line 10 phase I project", as the pull rod of the starting platform was slowly pulled down, the red shield cutter head turned rapidly. With the roar of the shield machine, waves of white foam continued to burst out, and the "Jinlong 8" shield machine successfully launched. This marks the completion of the first shield machine departure of line 10 phase I project, creating conditions for the tunnel to be opened on schedule

113d sprint 2.5 shield machines simultaneously drive through the underground works

in order to ensure the progress of the project, 11 shield machines are planned to be invested in the first phase of line 10 to drive at the same time. Among them, the scope of civil engineering bid 3 covers the air shaft from Huaxing station to Hua (Huaxing station) - Jin (Jinhua station), with a length of 1186.6 meters (measured by the mileage of the left line), including air shaft, section and OCC control center, which is constructed by China Railway Construction 15th Bureau. The middle air shaft is a two-story underground structure, which is constructed by open excavation method. The OCC control center is a frame structure with two floors underground, three floors locally and nine floors above the ground. The section from Huaxing station to Hua (Huaxing station) - Jin (Jinhua station) air shaft is constructed by shield method

at 9 a.m., the plastic granulator is also a major energy consumer in China. At the shield sinking position between Huaxing station and Jinhua station near the first section of Chuma Road, as the pull rod of the starting platform is slowly pulled down, the red shield cutter head rotates rapidly. With the roar of the shield machine, waves of white foam continue to spray out, and the "Jinlong 8" shield machine successfully realizes the initial tunneling

according to the relevant personnel of Chengdu Metro, the "Jinlong 8" earth pressure balance shield machine, which undertakes this task, is tailored to adapt to the complex geological conditions of water rich sand and pebbles in Chengdu. The tunneling task is the left line of the air shaft from Huaxing station to Hua (Huaxing station) - Jin (Jinhua station)

a total of 6 stations are set up to reach the T2 terminal of Shuangliu Airport.

according to Chengdu Metro, the first phase of Chengdu Metro Line 10 adopts the "investment and financing + design and construction general contracting" mode, and the general contractor of the project is China Railway Construction Co., Ltd. The line is about 10.9 kilometers long, all of which are underground lines, with a total of 6 stations, including taipingyuan station, Chujin station, Huaxing station, Jinhua station, airport station 1 and airport station 2

the line starts from taipingyuan station (transfer station with metro lines 3 and 7), goes down Jialing Road, crosses the West Ring Road and the Third Ring Expressway, goes south to chengshuang Avenue, connects Bayi Furniture City Business District, sets Chujin station, sets Huaxing station at the intersection of Xin'an Avenue and Wuhou Avenue, goes south along Guihua Road, goes down through the ring expressway to Maxin Road, and sets Jinhua station at the intersection of Maxin road and Jinhang road, The line crosses the Jiang'an River along Maxin road and enters the T1 terminal building, where the first airport station is set, and the second terminal airport station is set up along the reserved space inside the terminal building to T2 terminal building

the line supplier of the project will make troubleshooting plans for users within 12 hours and inform users that after completion, citizens can take the subway from the central urban area of Chengdu to Shuangliu International Airport directly, realizing "zero distance" transfer between air transportation and subway transportation
