Cast-in-place construction method of cast-in-place concrete bridge
The invention provides a cast-in-place construction method of a cast-in-place concrete bridge, and relates to the technical field of building construction. The cast-in-place construction method of the cast-in-place concrete bridge comprises the following steps that a full framing is erected, bottom formworks are sequentially installed on the full framing according to a bridge design drawing, the full framing is pre-pressed and adjusted, then webs and inner formworks are installed on the bottom formworks, and a steel reinforcement framework is installed; concrete pouring operation is sequentially carried out from low to high, in the pouring process, concrete pouring is carried out for the first time, a layered dislocation method is adopted, after 5-10 m of bottom formworks are poured, pouring of webs is completed in a layered mode, and after pouring of the last section of bottom formworks and webs is completed, circulating construction is carried out till concrete pouring of all structures is completed. According to the construction method, the pouring construction period of the box girder can be obviously shortened while the construction quality of the box girder is guaranteed, and the construction efficiency is improved.
本发明提出了一种现浇混凝土桥梁的现浇施工方法，涉及建筑施工技术领域。该现浇混凝土桥梁的现浇施工方法，其包括以下步骤：架设满堂支架，根据桥梁设计图纸在满堂支架依次安装底模板，并对满堂支架进行预压和调整，然后在底模板上安装腹板和内模，并安装钢筋骨架；按照从低到高的顺序依次进行混凝土浇筑作业，浇筑过程中，先进行第一次浇筑混凝土，采用分层错位法，浇筑完成5～10m的底模板后，再分层完成腹板的浇筑，完成上一段底模板和腹板的浇筑后，循环施工，直到完成所有结构的混凝土浇筑。此施工方法能够在保证箱梁施工质量的同时，明显缩短箱梁的浇筑施工工期，加快施工效率。
