Construction technology of extra-large bridge pier body
The invention relates to the technical field of abutment body construction, in particular to a construction technology of an extra-large bridge abutment body. The method comprises the following steps: 1, cleaning the top surface of a bearing platform, and measuring and setting out; 2, erecting a scaffold and setting a crawling ladder, namely selecting a bracket, mounting the bracket, arranging a working frame, setting up the working frame at a fixed distance and positioning, and constructing the working frame; 3, reinforcing steel bar processing and installation: reinforcing steel bar processing and installation; 4, comprehensive grounding; 5, settlement observation setting; sixthly, fence embedded parts are hung; seventhly, the formworks are installed and dismantled, wherein the formworks are installed and dismantled; 8, pier body concrete pouring; 9, carrying out padstone construction; and 10, concrete curing. Pouring segment formworks and formwork opposite drawing wires are used as a supporting system, horizontal connecting bolts of the formworks at the upper stage and the lower stage are used for temporary fixing to solve the vertical supporting problem, formwork vertical bolts are used for connecting to form a whole, the formworks are reinforced through finish rolling deformed steel bars, and a supporting and reinforcing system is formed.
本发明涉及墩台身施工技术领域,具体为一种特大桥梁墩台身的施工工艺。步骤包括:一、承台顶面清理和测量放样;二、脚手架搭设及爬梯设置:支架选择、支架安装、作业架布置、作业架搭设的定距定位、作业架施工;三、钢筋加工及安装:钢筋加工、钢筋安装四、综合接地;五、沉降观测设置;六、吊围栏预埋件;七、模板安装及拆除:模板安装、模板拆除;八、墩身混凝土浇筑;九、垫石施工;十、混凝土养护。本发明利用已经浇筑的节段模板和模板对拉丝作为支撑体系,利用上下阶段模板的水平联接螺栓临时固定解决竖向支撑问题,利用模板竖向螺栓联接形成整体、模板之间采用精轧螺纹钢加强,形成支撑、加固体系。
