Large-span segmental beam cantilever assembly process
The invention discloses a large-span segmental beam cantilever assembly process which comprises the following steps: mounting a bridge girder erection machine, replacing a steel support, mounting a large-span segmental beam and transversely moving the bridge girder erection machine to change amplitude. The installation process of the bridge erecting machine is improved, and the whole is broken into parts for installation; a steel support much smaller than a pier top beam section is adopted as a temporary support, and the requirement for hoisting equipment is lowered; steel supports and connecting cross beams are designed to complete transverse movement and span crossing of the bridge girder erection machine, and equipment manufacturing investment is reduced; a temporary pier body is additionally arranged, the large span is divided into a small span suitable for installation of a bridge erecting machine, and therefore the adaptability of the bridge erecting machine to installation of large-span segmental beams is met.
本发明公开了一种大跨度节段梁悬臂拼装工艺，包括以下步骤：架桥机安装、钢支撑置换、大跨度节段梁安装以及架桥机横移换幅；改进架桥机安装工艺，化整为零进行安装；采用比墩顶梁段小的多的钢支撑作为临时支撑，降低对吊装设备的要求；设计钢支撑和连接横梁以完成架桥机横移过跨，降低设备制作投入；增设临时墩身，将大跨度分为适用架桥机安装的小跨度，以满足架桥机对大跨度节段梁安装的适应性。
