Construction method for erecting multi-beam box girder by using single-arm bridge girder erection machine
The invention provides a construction method for erecting a multi-beam box girder by using a single-arm bridge girder erection machine, and relates to the technical field of railway bridge construction, and the construction method comprises the following steps: when the distance between bridge pier supporting pads is equal to a preset distance, the single-arm bridge girder erection machine adopts a four-supporting-leg hole passing method to complete hole passing; hoisting the box girder by a crane carriage of the single-arm bridge girder erection machine; when the distance between the bridge pier supporting pads is smaller than the preset distance, front auxiliary supporting legs of the single-arm bridge erecting machine are dismantled, machine arms of the single-arm bridge erecting machine are lengthened, and hole passing is completed through a balanced hole passing method; a transition carrying pole is installed on a lifting beam carrying pole of the crane carriage, and the crane carriage lifts the box girder through the transition carrying pole; the preset distance is the width of the front auxiliary supporting leg. Two different types of bridge girder erection machines do not need to be adopted on a construction line, the equipment and construction cost can be reduced, the construction efficiency is improved, the project progress is accelerated, and the bridge girder erection machines can be universally used when box girders of passenger transport lines and intercity railways are erected.
本发明提供了一种运用单臂架桥机架设多梁型箱梁的施工方法，涉及铁路桥梁施工技术领域，包括：当桥墩支垫间距等于预设间距时，单臂架桥机采用四支腿过孔法完成过孔；单臂架桥机的起重小车吊装箱梁；当桥墩支垫间距小于预设间距时，拆除单臂架桥机的前辅助支腿，加长单臂架桥机的机臂，采用平衡式过孔法完成过孔；在起重小车的吊梁扁担上安装过渡扁担，起重小车通过过渡扁担吊装箱梁；预设间距为前辅助支腿的宽度。本发明中无需在施工线路上采用两台不同类型的架桥机，可以降低设备和施工成本，提高施工效率，加快项目进展，并且架桥机能够在架设客运专线和城际铁路的箱梁时实现通用。
