Full-section incremental launching comprehensive construction method for UHPC steel-concrete composite beam
The invention discloses a UHPC steel-concrete composite beam full-section incremental launching comprehensive construction method. The method comprises the following steps that 10, a manufacturing site, an assembling site, an assembling and overlapping area and a cast-in-place maintenance area are arranged; 20, in the manufacturing site, bridge deck slabs and steel edge box blocks are machined and pre-matched; 30, the steel edge box block bodies are continuously matched to manufacture the steel edge box in the assembling site; 40, in the assembling and overlapping area, cross beams, small longitudinal beams and the steel edge boxes are spliced to manufacture steel beams, and the bridge deck slabs and the steel beams are overlapped; 50, in the cast-in-place maintenance area, a bridge deck slab wet joint is poured and maintained; and 60, incremental launching construction is carried out on the bridge deck slabs in the round until the incremental launching construction of the whole main bridge is finished. According to the UHPC steel-concrete composite beam full-section incremental launching comprehensive construction method, steel-concrete composite beam full-section incremental launching construction is adopted, welding operation during front-field installation of the main beam is reduced, and the overall construction quality is improved.
一种UHPC钢混组合梁全断面顶推综合施工方法，包括以下步骤：步骤10，设置有制造场地、拼装场地、拼装叠合区和现浇养护区；步骤20，在所述制造场地，加工桥面板和钢边箱块体并预匹配；步骤30，在所述拼装场地，将所述钢边箱块体连续匹配制作钢边箱；步骤40，在所述拼装叠合区，将横梁、小纵梁和所述钢边箱组拼制作钢梁，将所述桥面板与钢梁叠合；步骤50，在所述现浇养护区，对所述桥面板湿接缝浇筑及养护；步骤60，对该轮次所述桥面板顶推施工，直至整体主桥顶推施工完毕。本发明UHPC钢混组合梁全断面顶推综合施工方法，采用钢混组合梁全断面顶推施工，减少了主梁前场安装时焊接作业，提升了整体施工质量。
