Construction method for newly adding reinforcing bottom plate concrete under large-span bridge bearing platform
The invention relates to the technical field of building construction, in particular to a construction method for newly adding reinforcing bottom plate concrete under a large-span bridge bearing platform. According to the method, during construction, a scaffold is erected firstly, then pouring holes are measured and positioned, a detector is used for detecting distribution of a reinforcing mesh in the existing bearing platform, and coring and drilling are conducted to stagger originally-distributed reinforcing steel bars of the existing bearing platform; then chiseling and reinforcing steel bar installation are conducted on the connecting face of the existing bearing platform and the new bearing platform, and a newly-added bearing platform bottom plate shaping steel formwork is installed; then pouring tools are prepared and installed before concrete pouring, and self-compacting concrete is prepared in advance; and finally, concrete pouring is conducted on the newly-added reinforcing bottom plate of the bearing platform, the concrete pouring is required to be from far to near, and it is guaranteed that the concrete is continuous in the pouring process. The construction method is simple in construction and convenient to operate, manpower and material resources can be saved, it can be guaranteed that concrete pouring of the newly-added bearing platform and the newly-added reinforcing bottom plate under the existing bearing platform is dense, and the construction quality of the newly-added reinforcing bottom plate under the bearing platform is guaranteed.
本发明涉及建筑施工技术领域，具体涉及一种大跨度桥梁承台下新增加固底板砼的施工方法。该方法施工时先进行脚手架搭设，然后进行浇筑孔测量定位，使用探测仪探测既有承台内部钢筋网分布，取芯钻孔错开既有承台原分布钢筋；随后对既有承台与新承台连接面进行凿毛及钢筋安装，并进行新增承台底板定型钢模板安装；接着进行混凝土浇筑前的浇筑工具准备及安装，提前进行自密实混凝土的试配；最后进行承台新增加固底板的混凝土浇筑，混凝土浇筑时要求由远到近，浇筑过程中保证混凝土连续不间断。该施工方法施工简单，操作便利，既能节省人力物力，又能够保证新增承台与既有承台下新增加固底板混凝土浇筑密实，保证了承台下新增加固底板的施工质量。
