Underwater concrete bottom sealing device for ultra-deep large-section open caisson and construction method
The invention relates to an ultra-deep large-section open caisson underwater concrete bottom sealing device and a construction method. The construction method comprises the main construction steps that a bottom sealing area is divided into zones and bins; assembling the horse riding type steel beams; mounting a horse riding type top section steel operation platform; laying a cushion layer pouring bracket; a water suction pump support is arranged; mounting a channel steel suspension beam; an operation construction platform for placing the hanging type hanging basket on the top is built; pre-burying, companding and forming a water collecting tank; mounting the rapid high-precision rib inserting device for the bottom plate; pouring a cushion layer; and pouring the bottom plate. The horse riding type top section steel operation platform is ingenious in design and convenient to assemble and disassemble, and the construction efficiency is greatly improved; by the adoption of the rapid high-precision steel bar inserting device for the bottom plate, rapid splicing can be achieved, on one hand, rapid positioning of bottom plate steel bars can be guaranteed, on the other hand, cyclic utilization can be achieved, the engineering cost is saved, and wide application prospects are achieved.
本发明涉及一种超深大断面沉井水下混凝土封底装置及施工方法，主要施工步骤包括：对封底区域进行分区分仓；骑马搁置型钢梁拼装；骑马搁置式顶部型钢操作平台安装；布设垫层浇筑支架；布设抽水泵支架；安装槽钢悬吊梁；搭设顶部搁置吊挂式吊篮操作施工平台；预埋压扩成型集水槽；安装底板快速高精度插筋装置；浇筑垫层；浇筑底板。本发明采用的骑马搁置式顶部型钢操作平台，设计精妙，装拆便捷，大大提高了施工效率；采用底板快速高精度插筋装置，可实现快速拼装，一方面可保障底板钢筋快速定位，另一方面可循环利用，节约了工程成本，具有广阔的应用前景。
