Steel box cofferdam construction process
The invention relates to a steel box cofferdam construction process. The steel box cofferdam construction process is characterized by comprising the following specific construction processes that S1, an assembling platform is erected; s2, a concrete bottom plate is hung; s3, side plates are installed; s4, lowering the steel hanging box; s5, pouring of a bottom sealing plate; s6, pumping water from the steel hanging box cofferdam; s7, the steel hanging box cofferdam is dismantled; the construction method comprises the following steps: firstly, carrying out preliminary construction on the outer wall of a steel casing higher than the highest tidewater position, mounting a profile steel bracket and a bottom plate supporting beam, then hoisting a concrete bottom plate and a steel hoisting box, and waiting for ebb tide; the steel corbel is rapidly removed, the steel hanging box is lowered, and bottom sealing concrete pouring is rapidly completed; in this way, it can be guaranteed that the steel hanging box is rapidly subjected to bottom sealing positioning at the installation position, the solidification degree of bottom sealing concrete during flood tide next time is guaranteed, construction efficiency is improved, the construction period is shortened, and cost is reduced; the whole structure is easy to assemble and disassemble, and construction efficiency is guaranteed.
本发明涉及一种钢箱围堰施工工艺，其特征在于：具体施工工艺如下：S1：拼装平台的搭设；S2：砼底板的吊设；S3：侧板的安装；S4：钢吊箱的下放；S5：封底板的浇筑；S6：钢吊箱围堰抽水；S7：钢吊箱围堰拆除；首先在钢护筒的外壁上高于最高潮水位置处开始进行初步的施工，将型钢牛腿及底板支撑梁进行安装，然后进行砼底板及钢吊箱的吊装，等待落潮后；快速将钢型牛腿移除，下放钢吊箱，并迅速完成封底砼浇筑；这样可以保证钢吊箱快速的在安装位置的封底定位，保证下次涨潮时封底砼的凝固程度，提高了施工效率，缩短了施工周期，降低了成本；整体结构装配拆卸简单，保证施工效率。
