铁路单线圆端型实体桥墩钢筋绑扎工法的改进

Improvement of reinforcing bar colligation of pier with round-end type in single track railway

考虑铁路桥墩数量多、结构单一的特点,组织合理、有效地标准化流水作业,对于提高工作效率,保证施工安全和质量意义重大。文章研究改进了传统的托盘、顶帽钢筋墩上绑扎施工方法,即先制作模具,再分类绑扎成型,最后拼接安装。该方法大幅提升了施工工效,显著降低了施工成本,在蒙内标轨铁路工程得以全线推广应用。

Considering the railway bridge with large number of piers and the single structure, reasonable organization and effectively standardized operations will make a significant sense to improve work efficiency, ensure the construction safety and quality. We improved the traditional reinforcing bar colligation technology from directly strapping the reinforcing bar on the tray and cap of pier, that is, to firstly making the moulds, and then strapping the reinforcing bar respectively, and finally installing together. This technology can greatly improve the construction efficiency, significantly reduce the construction cost, have been used successfully in the whole line of Mombasa-Nairobi Standard Gauge Railway.
