8 On the 20th of the month, the final 49.5-meter-long truss was carefully lifted into its designated docking position, marking the successful completion of the steel structure project for the Jinan East High-Speed Train Depot, undertaken by Yuegong Steel Structure Shandong Company.

Jinan East Railway Station is located at the Jiqing High-Speed Rail Hub in the eastern suburbs of Jinan. It is Shandong Province’s largest three-dimensional, on-site integrated passenger transport hub, with a construction scale twice that of the current Jinan West Railway Station and a total floor area of 23,600 m². ² It comprises two floors above ground and two floors underground, with a total construction cost of RMB 20.72 million. The main structural system features concrete columns and large steel‑section trusses, while the roof panels are lightweight precast slabs with steel edge frames and thermal insulation.

The project was undertaken under general contract by China Railway Tenth Bureau, with the steel‑structure works subcontracted to our company. Construction commenced on June 24, 2017, facing tight deadlines and stringent quality requirements. The most challenging component was the 83 trusses, each measuring 49.5 meters in length and 5.0 meters in height; their substantial size posed significant logistical hurdles for workshop fabrication and transportation. To address the complexities of intricate fabrication, extensive welding, tight schedules, and difficult transport, Shandong Company convened two specialized meetings, bringing together representatives from the Technical Department, Manufacturing Department, Engineering Department, and Quality Control Department to deliberate on mitigation strategies. Following a thorough review of the design drawings, it was decided to adopt a segmented fabrication and transportation approach: each truss would be divided into three sections during detailed design, with final assembly and lifting carried out once the components arrived on site. This method facilitated both workshop processing and efficient loading and transport. Additionally, the company assigned extra technical personnel to provide on‑site technical briefings and process guidance to welders, ensuring high‑quality field welding. Furthermore, the project team installed two lifelines and safety nets on both the upper and lower surfaces of each truss, guaranteeing maximum safety. Construction coincided with the summer heat, yet workers persevered under scorching temperatures to accelerate progress. To minimize exposure to high‑temperature conditions, the project mobilized five large cranes and more than 80 workers simultaneously during steel‑component hoisting, enabling seamless execution of assembly, welding, and roof‑covering operations. After 57 days of dedicated effort, the steel‑structure works at the Jinan East High-Speed Train Depot were completed ahead of schedule and to the satisfaction of both the general contractor and the client.
