en.Wedoany.com Reported - On June 28, the northern extension of Phase 2 of Shenzhen Metro Line 13 officially opened for operation. As a key north-south transportation corridor in Shenzhen, this line not only provides an efficient and convenient "new option" for cross-district travel but also marks a crucial step in extending the city's rail transit network northward.
The newly opened northern extension of Phase 2 starts from Shangwu Station (exclusive) of Phase 1 and extends northward to Lisonglang Station, covering a total length of 19.25 kilometers with 11 stations. It is understood that the track-laying work for the entire northern extension was undertaken by China Railway Third Bureau.
Facing challenges such as long line length and significant interference from multi-disciplinary cross-operations, the project team established the concept of "high-standard construction, intelligent empowerment, and high-quality delivery" from the outset. During construction, the team innovatively adopted a "segmented deployment, three-dimensional advancement" model, scientifically setting up four track-laying bases and 12 workfaces, quickly achieving synchronized multi-point construction and efficient line-wide progress.
In tackling technical challenges, the project team focused on technological innovation, applying prefabricated track base construction measurement technology. By replacing traditional manual control with a steel wire control network, they successfully controlled construction precision errors to the millimeter level. Meanwhile, relying on the intelligent dispatching and safety management platform for the track area, they achieved unified dispatching and dynamic monitoring of 12 workfaces, efficiently completing the track-laying task under safe and controllable conditions, laying a solid foundation for the line's scheduled opening.
It is reported that once the northern extension of Phase 2 is connected with Phase 1, it will effectively link the three major administrative districts of Nanshan, Bao'an, and Guangming. This will not only significantly improve commuting efficiency for residents but also further deepen inter-regional connectivity, injecting strong momentum into the balanced development of Shenzhen as a "Pilot Demonstration Zone."
