At 7 a.m. on March 10, the roar of rotary drilling rigs pierced the air as the construction site of the separated bridge underpassing the Beimo Expressway at DK157+494 — a key control node of the Fujia Railway reconstruction project — bustled with activity. Pile foundation No. 0 of Abutment No. 0 of the A and C ramp bridges was officially drilled, marking the project's formal entry into the substantive construction phase after the Spring Festival. As the core control works in the crossing construction between the Fujia Railway and the Beimo Expressway, this underpass separated ramp bridge has a total length of 82 meters and a total of 28 designed pile foundations. Combining high technical difficulty with complex coordination factors, it is the key bottleneck for opening up construction along the entire line.

The smooth drilling of the first pile foundation not only verified the feasibility and scientific soundness of the construction plan, but also accumulated valuable experience for the subsequent construction of the bridge's substructure. At the construction site, the project's technical director kept watch throughout, strictly controlling key parameters such as mud specific gravity and drilling speed to ensure that hole-forming quality met design specifications, laying a solid foundation for subsequent construction.

From gathering strength during the winter break to accelerating resumption of work, from unified thinking to safety assurance, from adequate material reserves to the drilling of the first pile, the Fujia Railway reconstruction project department has fully set off a spring construction boom with precise planning, pragmatic measures and high morale.

In the new year, all builders will continue to carry forward the craftsman spirit of overcoming difficulties and striving for excellence, closely focusing on the core goals of project safety, quality, schedule and efficiency. Guided by capacity improvement, with safe production as the bottom line and engineering quality at the core, they will unite their efforts and work in earnest to drive continuous new breakthroughs in project construction, contributing solid strength to the high-quality completion of the Fujia Railway construction task and to serving local economic and social development.
