The invention provides a swinging and moving type installation method for a side span beam section. The swinging and moving type installation method comprises the following steps that (1) a transverse moving temporary support is built below a cable bent tower; (2) vertically lifting a single-section beam section of the side span to the position above the horizontal height of the transverse moving temporary support and swinging the single-section beam section to the transverse moving temporary support; (3) repeating the step (2) to hoist the single-section beam sections of the constructed side span beam section to the transverse moving temporary support, and sequentially arranging the single-section beam sections one by one along the bridge direction and welding the single-section beam sections into a whole; (4) the side span beam section welded into a whole is lifted to be higher than the designed height in the vertical direction, and the side span beam section swings towards the side span side to be above the pier top of the transition pier; and (5) the side span beam sections are connected to the top of the transition pier and connected with other side span beam sections, and the midspan sides of the side span beam sections are connected with slings, located on the midspan sides, of the cable bent towers. The problem that a transport vehicle and a transport ship cannot be in place at the cable bent tower side span beam section construction position is solved, the influence of the construction environment on the construction progress is reduced, the construction period is shortened, and the construction cost is reduced.

    本申请提供一种边跨梁段的荡移式安装方法,其包括以下步骤:(1)在索塔下方搭建横移临时支架;(2)沿竖向提升边跨的单节梁段至横移临时支架的水平高度上方并荡移至横移临时支架上;(3)重复步骤(2)吊装所施工的边跨梁段的单节梁段至横移临时支架上,沿顺桥向将单节梁段逐个依次排布并焊接形成整体;(4)将焊接为整体的边跨梁段沿竖向提升到设计高度以上,并朝边跨侧荡移至过渡墩墩顶上方;(5)将边跨梁段落至过渡墩墩顶,与其他边跨梁段连接,边跨梁段的中跨侧与索塔位于中跨侧的吊索连接。本申请解决了索塔边跨梁段施工位处存在的运输车和运输船无法就位的问题,降低施工环境对于施工进程的影响,缩短施工工期和降低施工成本。
