en.Wedoany.com Reported - On March 31, the Pinglu Canal Shajing Qinjiang Bridge officially opened for operation. So far, 25 out of the 27 planned overpass bridges for the Pinglu Canal have been completed and opened to traffic, marking the final stage of the entire line's bridge project and creating a crucial condition for the full navigation of the canal.

The bridge adopts a double-tower cable-stayed structure, with the main towers featuring a "gate"-style design, each standing 113 meters high. The crossbeam on the bridge tower draws inspiration from a giant ship breaking through waves, creating the image of a "gateway," while incorporating cultural elements of "grand gates" and "awakening lions." This design presents the unique charm of auspiciousness and prosperity in the Lingnan region within a modern engineering project.

The bridge has a total length of 896 meters, a main span of 270 meters, a design speed of 60 km/h, a deck width of 40 meters, and features eight lanes in two directions. Its structural safety rating is Level 1. With a navigational clearance height of 19.1 meters and a width of 234 meters, it can accommodate the passage of 5,000-ton vessels.

Located at the estuary of the Qin River, the bridge construction faced multiple challenges, including complex tidal conditions, proximity to a mangrove ecological reserve, ecological protection requirements, hydrological interference, and a tight schedule. During the construction process, the management team innovatively adopted a combined technique of "cantilever casting with hanging baskets + cast-in-place with ground-supported formwork." All large temporary facilities were positioned to avoid the navigation channel, ensuring no interference between bridge and channel construction. Simultaneously, by applying the "Construction Method for Synchronous Tower and Girder Construction of Cable-Stayed Bridges with Concrete Portal Pylon and Box Girders" and establishing an integrated management and control system of "real-time monitoring + dynamic adjustment," technological breakthroughs were achieved in areas such as structural anchorage reinforcement and refined girder segment construction, ensuring the bridge was completed on schedule.
