Bridge bottom plate pouring method
The invention discloses a bridge bottom plate pouring method which comprises the following steps that the pouring sequence of whole concrete is gradually carried out from the two ends to the middle; concrete is poured on the support, and transverse concrete construction is conducted; when concrete is poured, the concrete is pushed forwards along the cross section of the structure in a slope layer according to the heights of a bottom plate and a web plate of the box girder; during box girder construction, a girder bottom plate, a web plate and a top plate are poured in sequence. According to the construction pouring method, the concrete pouring sequence is controlled, the whole concrete pouring sequence is adopted, concrete pouring is carried out step by step from the two ends to the middle, when concrete pouring is carried out, forward pushing is carried out in a slope layer mode along the structural cross section according to the heights of a bottom plate and a web plate of the box girder, and when the box girder is constructed, the beam bottom plate, the web plate and a top plate are poured in sequence. The deformation amount and the position deviation amount after concrete forming are controlled, the construction quality is guaranteed, the project delivery period is ensured, and economic losses are avoided.
本发明公开一种桥梁底板浇注方法，所述桥梁底板浇注方法包括以下步骤：整体混凝土的浇筑顺序，由两端向中间逐步进行；在支架上浇筑混凝土，进行横向混凝土施工；浇注混凝土时，按箱梁的底板、腹板高度，沿结构横截面以斜坡层向前推进；箱梁施工时浇注顺序为依次浇筑梁底板、腹板和顶板。本发明通过控制混凝土的浇筑顺序，采用整体混凝土的浇筑顺序，由两端向中间逐步进行，浇注混凝土时，按箱梁的底板、腹板高度，沿结构横截面以斜坡层向前推进，箱梁施工时浇注顺序为依次浇筑梁底板、腹板和顶板的施工浇筑方法，使得混凝土成形后的变形量以及位置偏差量得到控制，保障了施工质量，确保了工程交付周期，避免造成经济损失。
