Construction method of prefabricated steel diaphragm plate and corrugated steel web combined small box girder
The invention relates to a construction method of a prefabricated steel diaphragm plate and corrugated steel web combined small box girder, which comprises the following specific steps of: designing a bridge, and determining parameters of each component; according to the design drawing, the corrugated steel web combined small box girder is prefabricated in a factory or a prefabrication site; the prefabricated corrugated steel web combined small box girder is transported and hoisted to a bridge abutment; the outer transverse steel partition plate assemblies of every two adjacent corrugated steel web combined small box girders in the transverse bridge direction are spliced through steel connecting assemblies and bolts. The concrete top plates of the two adjacent corrugated steel web combined small box girders in the transverse bridge direction are connected with each other through cast-in-place reinforced concrete wet joints; transverse splicing of each bridge span corrugated steel web combined small box girder is completed; the corrugated steel web combined small box girder is longitudinally spliced and assembled; and construction of other ancillary facilities of the bridge is completed. The combined small box girder transverse connection construction is convenient, the construction period is short, the construction quality is high, and the combined small box girder transverse connection construction method has obvious advantages in the aspects of the construction technology, later bridge maintenance and project cost reduction.
本发明是预制装配式钢横隔板波形钢腹板组合小箱梁的施工方法，具体步骤为：进行桥梁设计，确定各部件的参数；按照设计图纸，在工厂内或预制场地预制波形钢腹板组合小箱梁：将预制好的波形钢腹板组合小箱梁运输吊装于桥梁墩台上；横桥向相邻两片波形钢腹板组合小箱梁的外横钢隔板组件通过钢制连接组件和螺栓拼接；横桥向相邻两片波形钢腹板组合小箱梁的混凝土顶板通过现浇钢筋混凝土湿接缝相互连接；完成每一桥跨波形钢腹板组合小箱梁的横向拼接；进行波形钢腹板组合小箱梁纵向拼接装配；完成桥梁其他附属设施的施工。本发明的组合小箱梁横向连接施工方便、施工周期短、施工质量高，在施工工艺、后期桥梁维修、降低工程造价方面具有明显优势。
