In the "fight for four quarters, sprint for one hundred days" critical moment

Chengdu rail transit line under construction

Efficient and steady progress

So, the line you're concerned about

What's the latest development?

Take a look.

Ziyang rail transit line 9 continuous beams closed

Recently, Ziyang Line of rail transit across the Laoying River continuous beam successfully closed, marking the completion of the whole line of 9 cantilever cast-in-place continuous beam construction.

The closure of the continuous beam across the Laoying River, a total length of 144 meters, the main span of 64 meters, the main pier height of 37.5 meters, for the rail transit Ziyang line bridge laid a solid foundation.

In the construction process of Ziyang line of rail transit

Track builders overcome projects

Cross highways, expressways, rivers and other construction difficulties

To the high standard of "hanging under the basket will not drop a screw"

All 9 continuous beams are closed successfully

Live up to the expectations of the citizens of both places

High standard construction

Not a screw can fall off the basket

Before construction, the construction team of Ziyang Line of rail transit studied the plan in detail, sorted out the possible safety risks of each construction step, and formulated corresponding preventive measures to prevent safety risks from the source. During construction, the safety conditions of each key node and each process transformation are strictly confirmed to ensure that the construction personnel are in good condition, equipment and tools meet the safety standards, and safety measures are scientific and reliable; The use of fully closed hard pocket protection, to ensure that no screw falls under the hanging basket during the construction process, effectively ensure the construction safety and the safety of the road. The construction of 7 stations and 9 cantilever cast-in-place continuous beams on Ziyang Line of rail transit is a key control project of the whole line, which is the key node of the bridge connection. Ziyang Line of rail transit since the start of construction, always adhere to the "twin cities with the same standard", high quality and high standards to speed up the construction of the line, under the strong support of the parties in the two places, only three months to complete more than 90% of the preliminary work along the important tasks, only a year and a half to complete 78% of the civil work tasks. Up to now, 100% pile foundation, 99% cap and 98% pier column have been completed in the elevated section of Ziyang Line of rail transit. 368 trusses of prefabricated beams have been installed, 54.1% of the total. All the seven stations on the whole line have been capped, 66.3% of the total length of the shield has been completed, and the electromechanical and decoration work has also started.

Latest progress of other lines under construction

Rail transit Ziyang line construction is in full swing other rail transit lines under construction are also accelerating to see if you care about that one? The first stage of the Chengdu-Meishan line construction was completed on October 15, marking the official start of the Chengmei Line construction site. Shigao station is located in the protective green belt of 500kV Shanpeng Line high pressure corridor in Shigao Economic Development Zone, Meishan City. The station is set along the protective green belt roughly in a north-south direction. Attention to those who care about the progress of the third phase of the Line 10 project! Recently, the left and right lines of the shield section between Hongpailou Station and Gaoshengqiao Station of the third phase of Chengdu Rail Transit Line 10 have been successfully connected, which has laid a solid foundation for subsequent tracklaying and electromechanical operations.

The second phase of Line 17

On October 13, the left line shield was completed between Beilu Station and Tashuiqiao station in the second phase of Chengdu Rail Transit Line 17. The next day, the main earthwork excavation of Xidajie Station in the civil engineering fourth section of the second phase of Chengdu Rail Transit Line 17 was successfully completed.

The second phase of Line 19

The second phase of Line 19, which will connect the two airports, has been drawing much attention. On October 12, as the key equipment room of Terminal 2 of Shuangliu Airport was successfully handed over to the system unit, the installation of communication, signal and other system equipment of Chengdu Rail Transit Line 19 Phase II project was officially launched. The next day, electromechanical installation and decoration of Line 19 phase II project 2 section contact channel sample successfully passed acceptance, providing the basic conditions for the subsequent efficient promotion of the construction of section contact channel. On October 14, the main structure of the elevated section from Shimenkan to Sanshengsi Station of the first phase of Chengdu Rail Transit Line 27 passed the physical quality acceptance, providing solid conditions for the subsequent professional approach. The main structure of Shiyang Station of Chengdu Metro Line 30 phase I was completed on Oct 16, bringing the roof to nine stations. On the morning of the same day, the first phase of rail transit line 30 between Xiejiadu station and Zhujiang Road station, the right line of the shield broke through, the section successfully. At present, Chengdu Railway Group strictly controls production safety, strictly implements epidemic prevention and control, comprehensively improves management efficiency and ensures the fulfillment of construction management tasks on schedule and with high standards. More than 30,000 constructers are speeding up and working hard with full enthusiasm to invest in the project construction with extraordinary construction speed and quality to respond to the city and citizens' eager expectations with excellent achievements to present the Party's twenty largest!
