Installation method of through tied arch bridge
The invention provides an installation method of a through tied arch bridge. The installation method comprises the following steps that S1, an arch support to be assembled is lifted; S2, the arch support to be assembled is lifted to the designed elevation, and the arch support is firmly fixed after the relative position is adjusted; S3, a 50t crane is adopted to hoist and close the wind brace arch support; S4, after wind brace arch support folding is completed, the A-shaped supporting frame is installed, and then corresponding parts are disassembled; S5, a wind brace arch support is pushed; S6, the wind brace arch support is pushed to a bridge position where a second pier is arranged, a beam falls in place, a sling is mounted, and a guide beam and a second assembly bracket are dismounted; and S7, the A-type support and the pushing support are dismantled, the sling is tensioned, and construction is completed. According to the installation method of the through tied arch bridge, the structure is simple, and operation is convenient; the support consumption investment is reduced; the hoisting cost investment is reduced; the wind brace arch supports can be assembled in a matched mode, the installation accuracy is improved, and what is guaranteed is that the deviation is within the allowable deviation range; the construction safety risk is reduced.
本发明提供了一种下承式系杆拱桥的安装方法，安装方法如下：S1：对待拼装的拱助进行提升；S2：将待拼装的拱助提升至设计标高，调整相对位置后固定牢靠；S3：采用50t吊车吊装合拢风撑拱助；S4：完成风撑拱助合拢后，安装A型支撑架再拆卸相应部件；S5：顶推风撑拱助；S6：顶推至第二桥墩设置的桥位，落梁就位，安装吊索，拆除导梁和第二拼装支架；S7：拆除A型支撑与顶推支架，吊索张拉，施工完成；本发明的下承式系杆拱桥的安装方法结构简单、操作方便；减少支架用量投入；减少吊装费用投入；风撑拱肋可匹配拼装，提高安装精准，保证在允许偏差范围之内；降低施工安全风险。
