Extra-deep foundation pit permanent and temporary combined supporting frame beam-ring frame plate construction method
The invention relates to an ultra-deep foundation pit permanent and temporary combined supporting frame beam-ring frame plate construction method. The method comprises the steps of frame beam-ring frame plate bottom temporary supporting, reinforcement cage binding, frame beam-ring frame plate formwork erecting, dismounting-free pull rod built-in, cantilever-hanging combined operation platform erecting and concrete pouring. The rapid binding device has the beneficial effects that the rapid binding device for the steel reinforcement framework is beneficial for improving the binding efficiency of the frame beam-ring frame plate steel reinforcement framework; the problem that the pre-camber of the annular frame plate structure is difficult to set is solved through the jacks and the cushion blocks, and the pre-camber setting precision and efficiency are improved; different modes are adopted for bottom supporting according to the thickness of the annular frame plate, and the construction efficiency of a lower supporting structure of the frame beam-annular frame plate structure can be improved; the built-in integral disassembly-free pull rod is used for connecting the frame beam side formwork and the underground diaphragm wall, so that the stability of formwork erecting is improved; and an overhanging-hanging combined operation platform is arranged as an operation platform.
本发明涉及一种超深基坑永临结合支护框架梁‑环框架板施工方法，包括步骤：框架梁‑环框架板底部临时支撑、钢筋骨架绑扎、框架梁‑环框架板模板支设、内置免拆拉杆、悬挑‑吊挂组合式操作平台搭设和混凝土浇筑。本发明的有益效果是：钢筋骨架快速绑扎装置，有利于提升框架梁‑环框架板钢筋骨架绑扎效率；通过千斤顶和垫块解决了环框架板结构预拱度设置困难的问题，提高了预拱度设置精度和效率；根据环框架板的厚度采用不同方式进行底部支撑，有利于提升框架梁‑环框架板结构下部支护结构施工效率；采用内置整体免拆拉杆连接框架梁侧模和地连墙，提高了模板支设的稳定性；设有悬挑‑吊挂组合式操作平台作为操作平台。
