Large-span cast-in-place beam construction method
The invention belongs to the technical field of bridge construction, and discloses a large-span cast-in-place beam construction method which comprises the following steps: S1, completing construction of bridge bearing platforms and bridge piers on two sides of a road; s2, a plurality of stand columns are fixed to the bearing platform in the first direction through a crane, and gaps are reserved between the stand columns and the bridge piers; s3, bearing beams are installed on the tops of the multiple stand columns in the first direction, and trusses are installed on the bearing beams in the second direction; and S4, a support and a box girder formwork are installed above the truss, the box girder formwork is fixed to the support, and then concrete is poured into the box girder formwork to manufacture the box girder. By means of the method, large-span construction of the bridge can be achieved, the truss is high in strength, not prone to deformation and good in stability, and in the box girder construction process, a road below the box girder can normally pass through.
本发明属于桥梁建设技术领域，公开了一种大跨径现浇梁施工方法，包括以下步骤：步骤S1：完成道路两侧桥梁承台及桥墩的施工；步骤S2：利用吊车将多根立柱沿第一方向固定于承台上且与桥墩预留间隙；步骤S3：沿第一方向，在多个立柱顶部安装承重梁，以及沿第二方向，在承重梁上安装桁架；步骤S4：在桁架上方安装支座和箱梁模板，箱梁模板固定于支座上，然后向箱梁模板中浇筑混凝土以制成箱梁。通过上述方法，能够实现桥梁的大跨径施工，且桁架强度高，不易变形，稳定性较好，在箱梁施工的过程中，箱梁下方的道路能够正常通行。
