Viaduct cross-ground parallel bridge buttress full framing combined support and construction method thereof
The invention provides a construction method of a viaduct cross-ground parallel bridge buttress full framing combined support. The method comprises the steps of 1 conducting construction preparation;2 driving center parting strip steel pipe piles; 3casting bridge deck temporary buttresses in place; 4 erecting pier top longitudinal bailey beams and distributive girders; 5 erecting a full framing;6 pre-pressing the support; 7 conducting upper-layer box girder formwork erecting and pouring; and 8 dismounting a template and the support, namely erecting temporary supporting points on bridge decksright above bridge decks (buttresses) at the two ends of a ground bridge which is implemented in advance, erecting steel pipe pile foundation buttresses in the framing middle of the ground bridge, and erecting longitudinal Bailey longitudinal beams and profile steel distribution beams to form a combined support system for erecting the full framing. The problem of erecting of the cast-in-place boxgirder support of an overpass bridge is solved.
本发明提供一种高架桥跨地面平行桥梁支墩满堂组合支架的施工方法，该方法包括如下步骤：步骤一:施工准备；步骤二:中分带钢管桩打设；步骤三:桥面临时支墩现浇；步骤四:墩顶纵向贝雷梁和分配梁搭设；步骤五:满堂支架搭设；步骤六:支架预压；步骤七:上层箱梁立模浇筑；步骤八:模板、支架的拆除，通过在先行实施的地面桥梁两端桥台（支墩）处正上方桥面上搭设临时支点、在地面桥梁分幅中间搭设钢管桩基础支墩并搭设纵向贝雷纵梁和型钢分配梁进行满堂支架搭设的组合支架体系，解决上跨桥梁现浇箱梁支架搭设难题。
