en.Wedoany.com Reported - Recently, the cast-in-place box girder for the left side of the Tangchonghe Bridge, part of Contract Section 5 of the Gui-Chen Expressway in Hunan Province, China, was successfully poured, marking the full completion of the main structure construction for this bridge project. The right-side cast-in-place box girder had been successfully poured earlier. Project staff remained on the front line during the holiday period, with over 80 construction workers operating in rotating shifts.
The Tangchonghe Bridge is a key controlling bridge project within Contract Section 5 of the Gui-Chen Expressway. Building on the experience from the right-side construction, the project management department optimized the construction organization and strengthened process coordination. Strict control was enforced throughout the entire process, from support monitoring, rebar tying, and prestressed tendon positioning to concrete pouring and curing, ensuring that the beam alignment, internal quality, and structural dimensions all met standards. A group of young technical backbones and a youth突击队 undertook key tasks in the construction of this bridge project.
Facing challenges such as a complex mountainous construction environment and multiple交叉作业, the project management department implemented systems for safety inspections, hazard identification, and emergency duty shifts, ensuring safe, stable, and quality-controlled construction during the holiday period. The completion of the left-side box girder pouring has created conditions for subsequent bridge deck system construction and the connection between the tunnel and this bridge project section. Once completed, the Gui-Chen Expressway will connect Guidong to Chenzhou, improving the expressway network in the southern Hunan region.
