The invention discloses a construction method of an embedded bearing platform. The construction method comprises the following steps that a foundation pit is formed in bed rock; an overwater construction platform is erected between every two adjacent buoyancy tank sets; bottom-layer double-wall cofferdam sections are assembled on the overwater construction platform, the bottom-layer double-wall cofferdam sections are lifted, the overwater construction platform is disassembled, the bottom-layer double-wall cofferdam sections are descended into water, and the bottom-layer double-wall cofferdam sections float on the water surface; the bottom-layer double-wall cofferdam sections are moved to the position above the foundation pit; upper-layer double-wall cofferdam sections are assembled on thebottom-layer double-wall cofferdam sections to form a double-wall cofferdam, the double-wall cofferdam is sunk into the foundation pit, and the double-wall cofferdam is supported on the bed rock; a steel casing is installed in the double-wall cofferdam, and a pile foundation is arranged in the steel casing; and the bearing platform is constructed on the pile foundation. After the overwater construction platform is used for assembling the bottom-layer double-wall cofferdam sections, the bottom-layer double-wall cofferdam sections can be directly descended into the water, double-wall cofferdam installation can be completed on the premise that large overwater hoisting equipment cannot enter a site, construction is safe and reliable, and the construction cost is saved.
本发明公开了一种埋置式承台的施工方法，包括以下步骤：在基岩上设置基坑；在相邻两个浮箱组之间搭设水上施工平台；在水上施工平台上拼装底层双壁围堰节，抬升底层双壁围堰节，拆除水上施工平台，将底层双壁围堰节下降至水中，并浮于水面；将底层双壁围堰节移动至基坑上方；在底层双壁围堰节上拼装上层双壁围堰节，形成双壁围堰，将双壁围堰下沉到基坑中，并使双壁围堰支撑于基岩上；在双壁围堰中安装钢护筒，在钢护筒中设置桩基础；在桩基础上施工承台。利用水上施工平台来拼装底层双壁围堰节后，可直接将底层双壁围堰节下降至水中，能够在无法进场大型水上吊装设备的前提下完成双壁围堰安装，施工安全可靠，节省施工成本。
