Swing moving type vertical splicing construction method for side span beam section
The invention provides a swinging and moving type vertical splicing construction method for a side span beam section. The swinging and moving type vertical splicing construction method comprises the following steps that (1) a single-section beam section of a side span is hoisted from a transport ship located at a bridge site and swung and moved to the side span side of a tower column; (2) turning over a single beam section from a horizontal state to a vertical state, lowering and storing a beam; (3) the step (1) and the step (2) are repeated, the single beam sections are hoisted to the sliding support section by section, and after the tail beam section of the side span beam sections of the same span is turned to be in the vertical state from the horizontal state, vertical splicing installation is conducted; (4) the single-section beam section slides to the position under the beam section hoisted by the vertical hoisting station, the beam section is lowered to the beam section located on the sliding support to be in butt joint, the beam section which is in butt joint into a whole is lifted upwards, vertical splicing of the single-span beam section is completed, and the side-span beam section in the vertical state is adjusted to be in the horizontal state; (5) pulling one end of the side span beam section to the pier top of the auxiliary pier, and connecting the other end of the side span beam section through a sling; and (6) repeating the steps until the construction of the cable-free area girder section of the bridge is completed.
本申请提供一种边跨梁段的荡移式竖拼施工方法，其包括以下步骤：（1）将边跨的单节梁段从位于桥位处的运输船中起吊并荡移至塔柱的边跨侧；（2）将单节梁段由水平状态翻转至竖直状态，下放并存梁；（3）重复步骤（1）和（2）将单节梁段逐段吊装至滑移支架上，在同跨边跨梁段的末节梁段由水平状态翻转至竖直状态后，进行竖拼安装；（4）将单节梁段滑移至由竖向提升站吊装梁段的正下方，下放梁段至位于滑移支架的梁段上以对接，将对接为整体的梁段向上提升，完成单跨梁段的竖向拼接，将竖向状态的边跨梁段调整为水平状态；（5）将边跨梁段的一端牵放到辅助墩墩顶，另一端通过吊索连接；（6）重复上述步骤直至完成桥梁无索区梁段施工。
