10 On the morning of the 27th, the main arch of the “Liaocheng City Heilongjiang Road Bridge over the Tuhai River,” constructed by Yuegong Steel Structure Shandong Company, was successfully closed, marking the complete completion of the bridge’s main steel structure.

The Heilongjiang Road Bridge over the Tuhai River in Liaocheng City is a steel‑structured, through‑truss arch bridge with a main span of 160 meters. The main bridge has a total length of 252 meters and a width of 46 meters, making it the largest‑span arch bridge in western Shandong. Upon completion, it will be known as “the first arch bridge in western Shandong.” This bridge is also the nation’s first through‑truss steel arch bridge to employ an Ultra‑High Performance Concrete (UHPC) deck system. During construction, a dual‑gantry rapid‑erection bridging technique was adopted, ensuring controllable quality and high safety while significantly accelerating the construction schedule—saving six months compared with conventional bridge‑erection methods.

As the first extra-large steel‑structure bridge project undertaken by Yuegong Steel Structure Shandong Company, the Heilongjiang Road Bridge over the Tuhai River was entirely designed, fabricated, and installed by the company. With its massive component volumes and intricate structural configuration, the project posed exceptionally high fabrication and construction challenges. To meet these demands, Shandong Company assembled a highly skilled team, meticulously planned the construction schedule, and implemented rigorous measures across all phases—ranging from detailed design and fabrication to process control, project management, installation quality, and safety and progress oversight. Leveraging cutting‑edge technical expertise, robust construction capabilities, and cohesive teamwork, the company successfully overcame one hurdle after another, ensuring the timely achievement of the project’s intended objectives.

During the fabrication phase, nearly 50,000 bolt holes on the bridge were required to meet tolerances measured in microns. Through innovations in process workflows and improvements to tooling and equipment, the Shandong company maintained rigorous oversight of critical milestones, enforced stringent process controls, and strengthened quality inspections. As a result, the bridge fabrication was completed successfully, with an on-site installation hole‑alignment rate of 100%—with only two holes exhibiting minor misalignment—and both fabrication and installation accuracy earned high praise from the owner and the supervising agency.

With the successful closure of the Heilongjiang Road Bridge over the Tuhai River in Liaocheng City, Yuegong Steel Structure has further strengthened its control technologies in the fabrication and construction of large-scale, complex steel‑structure bridges, marking another solid step forward in the field of steel‑structure bridge engineering.

The first prefabricated steel‑frame residential project in Keqiao District—Building 112 of Jishan Shengda Jinfu—has topped out ahead of schedule.

Yang Xudong, Secretary of the Pingyin County Party Committee, and his delegation paid a visit to Shandong Yuegong to inspect and provide guidance on its work.
