Recently, at the construction site of the Taizicheng Grand Bridge on the Chongli Railway of the Beijing-Zhangjiakou High-Speed Railway, machines roared as a large rotary drilling rig stood on the work platform. The drilling of pile foundations No. 3-10, 12 meters long and 1.25 meters in diameter, marked the official start of construction of the Taizicheng Grand Bridge of the Chongli Railway Section 3 project.
The Taizicheng Grand Bridge is located northwest of Taizicheng Station. It is designed as a double-track bridge with a line spacing of 4.6 meters and a total length of 801.74 meters. During construction, the Taizicheng Grand Bridge will strictly implement the goal of a “quality project and intelligent Beijing-Zhangjiakou” railway, adhere to standardized operations, and complete the construction of this key supporting project for the Winter Olympics with high quality.
To ensure normal construction after the holiday, the project department made advance arrangements and carried out standardized construction of the on-site work platform, effectively ensuring the vertical stability of the rotary drilling rig and the smooth progress of the Taizicheng Grand Bridge construction. At the same time, the project department communicated with the supervision unit in advance, conducted pre-job training after the holiday for on-site workers, guards, and safety officers, and arranged full-time technicians, safety officers, and testers to provide on-site supervision and guidance at the construction site. To ensure construction quality and safety, special bridge construction plans and work instructions were formulated and distributed to cooperating personnel. The project leadership team strictly implemented the shift leadership system, held daily construction production coordination meetings, promptly resolved and coordinated problems in construction, and organized cooperating teams to quickly allocate sufficient labor, laying a solid foundation for a smooth start of construction after the holiday.
