Floating type double-wall steel cofferdam and high pile cap construction method
The invention discloses a floating type double-wall steel cofferdam and a high pile cap construction method.The steel cofferdam comprises an inner wall plate and an outer wall plate, the bottom of an interlayer between the inner wall plate and the outer wall plate is sealed through a horizontal annular plate, a suspension structure capable of suspending in water is defined, and a bottom support fixedly connected with the inner wall plate is arranged at the bottom of the area surrounded by the double-wall cofferdam structure; a bottom plate is laid on the bottom face of the bottom plate support and seals the bottom of the area surrounded by the whole double-wall cofferdam structure in the floating transportation process of the double-wall steel cofferdam, and a floating structure with the internal space isolated from external water is formed. A hole opening area capable of being cut off before pile foundation construction is arranged at the position, where a pile casing is arranged in a preset penetrating mode, of the bottom plate, and an annular supporting rib used for reinforcing a hole opening after hole opening is arranged around the hole opening area. The bottom plate isolates water inside and outside the area surrounded by the double-wall steel cofferdam structure in the floating transportation process, so that the double-wall steel cofferdam structure has large enough displacement and better floatability, launching and floating transportation of the floating type double-wall steel cofferdam are facilitated, and the floating type double-wall steel cofferdam structure has higher adaptability to the hydrological environment.
一种浮式双壁钢围堰及高桩承台施工方法，钢围堰包括内壁板和外壁板，内壁板和外壁板之间夹层的底部由水平环板封闭，围成可悬浮在水中的悬浮结构，在双壁围堰结构围绕区域的底部设置有与内壁板固定连接的底部支架，底板支架的底面铺设有底板，底板在双壁钢围堰浮运过程中封闭整个双壁围堰结构所围绕区域的底部，形成内部空间与外部水体隔绝的漂浮结构；底板上预定穿设桩护筒的位置设有能够在进行桩基施工之前切除的开孔区，围绕所述开孔区设有用于在开孔后加强孔口的环形支撑肋。底板在浮运过程中隔绝双壁围堰结构围绕区域内部与外部水体，使其具有足够大的排水量以及更好的漂浮性，有利于浮式双壁钢围堰下水和浮运，对水文环境具有更高的适应性。
