Construction method for large-span prefabricated erected steel-concrete composite beam
The construction method comprises the following steps of S1, construction of an annular trestle, S2, construction of an assembly support, S3, construction of a lifting station, S4, construction of a pier top bracket, S5, incremental launching construction of a steel tank beam, S6, erection of a bridge deck slab, and S7, superposition construction of the bridge deck slab, and system conversion of the steel-concrete composite beam is completed. The method provided by the invention comprises the following steps: firstly adopting a bidirectional synchronous incremental launching construction technology to complete erection of steel tank beams, then paving prefabricated bridge deck slabs by utilizing a bridge deck slab erection machine, and finally completing superposition of the bridge deck slabs and steel beams by jacking and falling beams by taking one link as a unit to complete system conversion, namely a combined construction method of firstly performing incremental launching, then erecting slabs and then performing superposition. Compared with the conventional whole-hole hoisting method, the method has the advantages that a large amount of desilting is not needed, a plurality of extra-large equipment is not needed to be input for a long time, a connecting plate is not needed to be arranged on each pier top, only certain walking top equipment and a plate erecting machine are needed to be input, the working procedures are tighter, and the construction efficiency is improved.
本发明公开一种大跨度预制架设钢混组合梁施工方法，包括以下步骤：S1，环形栈桥施工，S2，拼装支架施工，S3，提升站施工，S4，墩顶托架施工，S5，钢槽梁顶推施工，S6，桥面板架设，S7，桥面板叠合施工，完成钢混组合梁的体系转换；本发明提出的方法为先采用双向同步顶推施工技术完成钢槽梁架设后，再利用桥面架板机铺设预制桥面板，最后以一联为单位通过顶落梁完成桥面板与钢梁的叠合，完成体系转换，即先顶推、再架板、后叠合的组合施工方法；该方法相对前面所述常规整孔吊装方法，无需进行大量清淤，无需长期投入多个特大型设备，无需在每个墩顶设置连接板，只需投入一定步履顶设备以及架板机，工序更加紧密，施工效率得到提高。
