The invention discloses an independent dual-purpose buoyancy-adjustable buoy for marine towing and installation and a construction method. The buoyancy-adjustable buoy comprises a safety protection structure, an upper positioning structure, upper truss supporting legs, a lower positioning structure, a floating sleeve and a main buoy body. The safety protection structure is welded and fixed to the top end of the upper positioning structure, the lower portion of the upper positioning structure is inserted into the main buoy, upper truss supporting legs are fixedly arranged on the upper positioning structure, and the lower positioning structure and the floating sleeve are connected with the main buoy through a supporting plate. The main body buoy is composed of a fixed buoyancy cabin, an adjustable buoyancy cabin and a radiation rib plate, and the fixed buoyancy cabin and the adjustable buoyancy cabin respectively and independently control the two sets of pipelines. The buoy is simple in structure, easy to construct and install, low in comprehensive cost and suitable for auxiliary offshore towing and offshore jacking self-installation of the piling platform, and the offshore overall installation risk of the piling platform can be effectively reduced.
本发明公开了一种独立式海上拖航安装两用的浮力可调节型浮筒及施工方法,浮力可调节型浮筒包括安全防护结构、上定位结构、上桁架支撑脚、下定位结构、浮动套筒、主体浮筒;安全防护结构焊接固定于上定位结构顶端部,上定位结构下部插入主体浮筒内部,上定位结构上固定设置有上桁架支撑脚,下定位结构与浮动套筒通过支撑板与主体浮筒连接;主体浮筒由固定式浮力舱、调节式浮力舱、辐射肋板组成,固定式浮力舱、调节式浮力舱分别独立控制两套管路。该浮筒结构简单,施工安装简易、综合成本低,适用于打桩平台的辅助海上拖航及海上顶升自安装,可有效降低打桩平台海上整体安装风险。
