Overpass existing route steel beam suspension splicing construction method
The invention relates to the technical field of bridge construction, in particular to an overpass existing route steel beam suspension splicing construction method. The method comprises the following steps: S1, determining a steel beam welding position; S2, installing a steel beam lifting station at one end of the side span cast-in-place beam, and erecting a rotary crane on the completed beam face; S3, installing a totally-enclosed protection platform; S4, hoisting the steel beam to a ground beam transporting vehicle and transported to the position below a cantilever of the steel beam lifting station; S5, hoisting the steel beam to the beam surface beam transporting vehicle in the steel beam hoisting station; S6, transporting the steel beams to a rotary crane by the beam surface beam transporting vehicle, and placing the steel beams to the welding positions of the steel beams by the rotary crane; S7, installing a bridge deck, and enabling the rotary crane and the protection platform to move forwards; and S8, repeating the steps S4-S7 until the steel beams are closed. In the whole construction process, rapid suspension splicing of the steel beams can be achieved, safe operation of the existing railway line can be guaranteed, the construction efficiency is high, and the engineering cost is saved.
本发明涉及桥梁施工技术领域，具体涉及一种上跨既有路线钢梁悬拼施工方法，包括以下步骤：S1.确定钢梁焊接位置；S2.在边跨现浇梁一端安装钢梁提升站，并在已完成梁面上搭设旋转吊机；S3.安装全封闭防护平台；S4.钢梁吊装上地面运梁车，并运输到钢梁提升站的悬臂下方；S5.钢梁提升站钢梁吊装到梁面运梁车上；S6.梁面运梁车将钢梁运输到旋转吊机处，旋转吊机将钢梁放置到钢梁焊接位置处；S7.安装桥面板，旋转吊机和防护平台前移；S8.重复步骤S4‑S7直至钢梁合拢。本发明整个施工过程既可实现钢梁的快速悬拼，又可保证既有铁路线的安全运营，且施工效率高，节约工程成本。
