Pier column, cover beam and T beam integrated bridge girder erection machine installation and construction method
The invention discloses an installation and construction method of a pier column, cover beam and T beam integrated bridge girder erection machine. The method is suitable for conventional fabricated bridges; a T-beam is installed through a front supporting leg and a middle supporting leg (rear span), pier studs, a bent cap and the T-beam can be installed in a staggered-span mode at the same time, the span of the bridge is 25 m, a bridge erecting machine with the length of 66 m is adopted in combination with the span of the bridge, and if the span of the bridge exceeds 25 m, the length of the bridge erecting machine and parameters of a main beam are changed. Staggered-span installation is that according to the project, for example, a bent cap is installed on the first span (pier studs are installed), and pier studs can be installed on the second span. According to the method, large-tonnage hoisting equipment is not needed to hoist the pier columns and the cover beams, only one integrated bridge girder erection machine is needed to achieve installation of the pier columns, the cover beams and the T-shaped beams, the construction process is optimized, construction is relatively convenient, the organization and coordination difficulty of various mechanical equipment is lowered, and meanwhile safety risks caused by cross operation of the mechanical equipment are lowered.
本发明公开了一种墩柱、盖梁、T梁一体式架桥机安装施工方法；适用于常规的装配式桥梁；利用前支腿与中支腿（后跨）安装T梁，可实现墩柱、盖梁及T梁错跨同时安装[本项目桥梁跨径为25m，结合本项目桥梁跨度采用长度66m的架桥机，若超过25m桥梁跨度应对架桥机长度及主梁参数进行更改。错跨安装即：按本项目为例第1跨安装盖梁（墩柱已安装完成），第2跨可安装墩柱]。本方法不需要大吨位吊装设备吊装墩柱、盖梁，只需要一台一体化架桥机实现墩柱、盖梁、T梁安装，优化了施工流程，施工相对方便，降低了各种机械设备组织协调难度，同时降低了机械设备交叉作业带来的安全风险。
