Construction method of steel-concrete composite beam T bridge
The invention relates to the technical field of bridge construction, in particular to a steel-concrete composite beam T bridge construction method which comprises the following steps that a plurality of steel plate beams are prefabricated, the steel plate beams comprise concrete beams, steel beams are arranged at the bottoms of the concrete beams, and the steel plate beams are sequentially hoisted to a bridge; a wet joint along the bridge direction is formed between the adjacent concrete beams in the transverse bridge direction, and a wet joint along the transverse bridge direction is formed between the adjacent concrete beams in the transverse bridge direction; the adjacent steel beams are welded in the bridge direction; the wet joints in the bridge direction and the wet joints in the transverse bridge direction are poured; and pouring for second-stage pavement. The steel plate beam is integrally prefabricated, then whole-hole hoisting is conducted, the construction steps of bridge erecting and hoisting construction are simplified, the bridge construction efficiency is improved, the first-stage load is directly borne by the combined section of the concrete beam and the steel beam, the steel consumption is reduced, and the cost input is reduced.
本发明涉及桥梁施工技术领域，具体涉及一种钢混组合梁T桥建造方法，包括如下步骤：预制若干片钢板梁，所述钢板梁包括混凝土梁，所述混凝土梁底部设有钢梁，将若干片钢板梁依次吊装上桥，在横桥向方向上相邻混凝土梁之间形成顺桥向湿接缝，在顺桥向方向上相邻混凝土梁之间形成横桥向湿接缝；在顺桥向方向上将相邻钢梁进行焊接；浇筑所述顺桥向湿接缝和横桥向湿接缝；浇筑二期铺装。本发明通过整体预制钢板梁，进而进行整孔吊装，简化桥梁架设吊装施工的施工步骤，提升桥梁施工效率，一期荷载直接由混凝土梁和钢梁联合截面承担，减少用钢量，降低成本投入。
