On June 30, after 914 days of intensive efforts, Renmin Square Station, the deepest station on Changchun Rail Transit Line 5, completed all main structure construction, laying a solid foundation for subsequent ancillary works.

It is understood that the station features an underground two-story, three-span island-type design and serves as an interchange station between Line 1 and Line 5. The station is 205 m long, with a standard section width of 24.1 m, a maximum depth of 34 m, and an average overburden of 14 m, making it the deepest station on the entire line.

To ensure safe and high-quality completion of the construction goals, the contractor adopted a series of measures. In terms of land acquisition and demolition, it coordinated deeply with relevant departments, effectively accelerating the pace of demolition. At the same time, based on actual site conditions, it vigorously carried out design changes, adding a temporary shaft in the middle of the station and a new auxiliary construction passage in the existing working shaft, effectively solving the problem of insufficient construction space.

Meanwhile, the contractor strictly controlled major risk sources, key processes, and critical parts, firmly implemented the red lines of safety control, safety technical disclosures, and safety management documents, strengthened three-level safety education and safety training, enhanced interactive inspections, and built a systematic management defense line.

In addition, in light of the construction characteristics of numerous sites and a wide scope, the contractor, following the principles of "centralized management, unified command, clear responsibilities, and lean efficiency," assigned responsibilities to individuals and pressed them down level by level, innovatively established a "production-technical shaft manager" system, and strengthened shaft construction control. It strictly followed the construction plan, optimized construction organization and tooling/processes, innovatively produced 6 simple trestles and 2 sets of triangular formwork supports for the station arch closure and side wall construction, adopted alternate-bay operation, and completed the station arch closure work one and a half months ahead of schedule.

At present, apart from Renmin Square Station, the main structure construction of Dajing Road Station, the other major station in this section, is also progressing in an orderly manner.
