Arch bridge steel stand column installation line shape accurate adjustment method and adjustment device
The invention relates to the technical field of arch bridge engineering. The invention particularly relates to an arch bridge steel stand column installation line shape accurate adjustment method. Firstly, guide positioning pieces are mounted at the lower ends of a to-be-mounted stand column; the directions of the upper and lower ends of the to-be-mounted stand column are adjusted through hoistingequipment; then the to-be-mounted stand column is hoisted to the position above the mounted stand column installed on the arch bridge; the guide positioning piece at the lower end of the stand columnto be mounted is embedded into the mounted stand column; in the butt joint process, the connecting holes in two butt joint flange plates are aligned; and a jack is arranged on a supporting lower support, the to-be-mounted stand column is transversely pushed through a jack, the transverse position of the to-be-mounted stand column is adjusted, the to-be-mounted stand column is aligned with the mounted stand column, finally, the butt joint positions of the to-be-mounted stand column and the mounted stand column are welded, and the jack and the supporting lower support are detached. On the premise that the linear quality of the stand column to be mounted is guaranteed, the installation efficiency is improved, safety risks are reduced, and the construction cost is reduced.
本发明涉及拱桥工程技术领域，具体涉及一种拱桥钢立柱安装线形精确调整方法，首先在待安装立柱下端安装导向定位件，通过吊运设备调整待安装立柱的上下两端的方向，然后将待安装立柱吊运至已安装在拱桥上的已安装立柱上方，通过待安装立柱下端的导向定位件嵌入到已安装立柱上，对接过程中使两个对接法兰盘上的连接孔对齐，在支撑下支座上设置千斤顶，通过千斤顶横向顶推待安装立柱，调整待安装立柱的横向位置，使待安装立柱与已安装立柱对齐，最后将待安装立柱与已安装立柱的各对接处进行焊接，拆除千斤顶及支撑下支座。本发明在确保待安装立柱线形质量前提下、提高安装效率、减少安全风险，降低施工成本。
