Large-span and wide-width steel-concrete composite beam bridge deck concrete one-time paving forming method
The invention relates to the technical field of concrete filled steel tube arch bridge construction, and discloses a large-span and wide steel-concrete composite beam bridge deck concrete one-time paving forming method which comprises the following steps: S1, checking and cleaning a steel bridge deck; s2, a formwork is installed; s3, walking rails are arranged through the embedded steel plates; step S4, mounting a truss type full-width paver; step S5, pre-walking inspection of the paver; step S6, preparing for pumping; s7, bridge deck concrete is synchronously and symmetrically pumped and paved; step S8, concrete curing; a transverse framing and longitudinal sectioning bridge deck pavement construction method is changed, the walking rails are arranged through the pre-buried steel plates, one-time pavement forming of bridge deck concrete can be achieved, the construction period is greatly shortened, concrete loss is reduced, the construction cost is lower, the working efficiency is improved, shrinkage cracks of concrete caused by creeping of a bridge deck slab are reduced, and the construction quality is improved. The cracking risk is effectively reduced, the market space and the development prospect are wide, and the environmental protection and social benefits are remarkable.
本发明涉及钢管混凝土拱桥施工技术领域，且公开了一种大跨、宽幅钢混组合梁桥面混凝土一次摊铺成型方法，包括以下步骤：步骤S1、钢桥面检查与清洗；步骤S2、模板安装；步骤S3、利用预埋钢板布设行走轨道；步骤S4、桁架式全幅摊铺机安装；步骤S5、摊铺机预走检验；步骤S6、泵送准备；步骤S7、桥面混凝土同步对称泵送和摊铺；步骤S8，混凝土养护；本发明改变了横向分幅、纵向分段桥面铺装施工方法，利用预埋钢板布设行走轨道，能实现桥面混凝土一次摊铺成型，大幅节约施工工期，降低混凝土的损耗，施工成本更低，提高了工作效率，减少凝土因桥面板的蠕动产生收缩裂缝，有效降低开裂风险，具有广阔的市场空间和发展前景，环保和社会效益显著。
