Seabed vacuum pipeline and pile foundation bearing platform structure beneficial to reducing buoyancy
The invention discloses a seabed vacuum pipeline and pile foundation bearing platform structure beneficial to reducing buoyancy. The shape of the concave arc surface of a bearing platform is properly set, the concave arc surface of the bearing platform is tightly attached to a vacuum pipeline, tight attachment is required, no gap exists, water seepage is avoided, and the vertical upward partial pressure of seawater borne by the vacuum pipeline is reduced, so that buoyancy borne by the seabed vacuum pipeline can be reduced, upward tension transmitted by the pipeline to a seabed pile foundation is minimized, and the requirement for the uplift performance of the pile foundation is lowered. The bearing platform structure comprises the pile foundation, the bearing platform, the vacuum pipeline and a pipe hoop and has the advantages of the simple structure and convenience in manufacturing and installation, and the buoyancy reducing thought and arrangement provided by the invention provide reference for future seabed vacuum pipeline construction and optimal design.
本发明公开一种有利于减小浮力的海底真空管道桩基承台结构，通过适当设置承台凹圆弧表面形状，并使承台凹圆弧面跟真空管道密贴，要求密贴、无缝隙、不渗水，减小真空管道所受海水垂直向上的分压，从而有利于减小海底真空管道所受浮力，使管道对海底桩基传递的向上拉力最小化，进而降低对桩基础抗拔性能的要求。基台结构包括桩基、承台、真空管道和管箍，其结构简单，便于制作与安装，本发明给出的减小浮力思路与设置给将来海底真空管道建设与优化设计提供借鉴。
