Floating splicing construction method for deepwater double-wall steel cofferdam
The invention discloses a floating splicing construction method for a deepwater double-wall steel cofferdam. A low-position splicing platform is arranged on a steel casing on the outermost periphery of a pile foundation construction sea area in a surrounding mode; then the multiple cofferdam blocks are conveyed to a low-position assembling platform and assembled, and a bottom section cofferdam unit is defined by the multiple cofferdam blocks; a hoisting system is installed at the top of the steel casing, then the low-position splicing platform is dismantled, and the hoisting system lowers the bottom section cofferdam unit till the bottom section cofferdam unit floats on the sea surface; and then a plurality of cofferdam blocks are conveyed to the top of the bottom section cofferdam unit to be assembled one by one till a complete cofferdam unit is assembled on the top of the bottom section cofferdam unit, so that one-time cofferdam heightening construction is completed, the heightened cofferdam sinks under the gravity of the cofferdam and automatically floats on the sea surface, then the cofferdam blocks continue to be assembled on the heightened cofferdam, and the whole cofferdam unit is assembled on the bottom section cofferdam unit. And the cofferdam height addition construction is continued until the cofferdam is stably implanted into the bed. The method has the effects that the investment of offshore hoisting equipment is reduced, and the occupied sea area space is greatly reduced.
本申请公开了一种深水双壁钢围堰浮拼施工方法，通过将低位拼装平台围设在桩基施工海域处最外围的钢护筒；然后在若干围堰块运至低位拼装平台并进行拼装，若干围堰块围合形成底节围堰单元；接着在钢护筒顶部安装吊放系统，接着拆除低位拼装平台，吊装系统将底节围堰单元下放，直至底节围堰单元自浮于海面；接着将若干围堰块运至底节围堰单元顶部进行逐一拼装，直至在底节围堰单元顶部拼装出完整的围堰单元，从而完成一次围堰接高施工，接高后的围堰在自身重力下下沉，并自浮于海面，接着继续在接高后的围堰上拼装围堰块，继续进行围堰接高施工，直至围堰稳定着床。本申请具有减少海上吊装设备投入以及改善对海域空间占用大的效果。
