Layered and partitioned pouring construction method for large-size bearing platform
The invention relates to a layered and partitioned pouring construction method for a large-size bearing platform, which comprises the following steps of: driving steel sheet piles along an excavation side line of a bearing platform foundation pit, and pouring bottom sealing concrete; a movable operation platform is erected through the horizontal ring beams and the longitudinal steel supports on the lowermost layer; carrying out bearing platform pouring construction layer by layer from bottom to top until all the bearing platforms are constructed; after the straining beam reinforcing mesh is bound, the straining beam reinforcing mesh is integrally hoisted into the foundation pit and is fixedly connected with the bearing platform reinforcing mesh through vertical locking reinforcing steel bars; mounting a straining beam side mold and pouring straining beam concrete. The method has the beneficial effects that the non-dismantling formwork is adopted at the boundary of the bearing platform and the straining beam, the formwork installation difficulty is lowered, formwork dismantling operation does not need to be conducted in the later period, and the construction period is shortened; the straining beam reinforcing mesh adopts an integral binding and on-site hoisting mode, so that the on-site construction efficiency is improved; in addition, the straining beam longitudinal bars and the bearing platform longitudinal bars are connected through the vertical locking steel bars, the integrity of the structure is guaranteed, and the bearing capacity of the structure is improved.
本发明涉及一种大体积承台分层分区浇筑施工方法，包括步骤：沿承台基坑开挖边线打入钢板桩，浇筑封底混凝土；依托最下层的水平圈梁和纵向钢支撑架设移动作业平台；从下到上逐层进行承台浇筑施工，直至承台全部施工完成；系梁钢筋网绑扎完成后整体吊运至基坑内使用竖向锁定钢筋与承台钢筋网连接固定；安装系梁侧模浇筑系梁混凝土。本发明的有益效果是：承台与系梁分界处采用免拆模板，降低了模板安装的难度，且后期无需进行拆模作业，缩短了施工周期；系梁钢筋网采取整体绑扎、现场吊装的方式，提升了现场施工效率；另外，系梁纵筋与承台纵筋通过竖向锁定钢筋连接，保证了结构的整体性，提升了结构的承载能力。
