Ⅰ型轨道板预制施工工艺与造价分析

On construction craft and costs analysis for Ⅰ-shape track slab precasting

结合石太客运专线Ⅰ型轨道板预制的成功经验,对轨道板预制的模型安装及要求、钢筋加工、混凝土施工及养护、预应力施工、轨道板存放等关键技术以及轨道板的造价组成进行了深入详细的剖析,为今后的客运专线Ⅰ型轨道板的推广应用提供有益的参考。

By combining with the successful experience for Ⅰ -shape track slab precasting on Shijiazhuang to Taiyuan passenger special line, the paper analyzes some key technologies, including the model installation and requirement, the reinforced processing, the concrete construction and maintenance, the precasting construction, and track slab storage, as well as the costs components for the track slab, so as to provide helpful reference for extending the application of the Ⅰ -shape track slab in future passenger special line.
