Offshore fixed structure foundation negative pressure cylinder and installation method
The invention discloses an offshore fixed structure foundation negative pressure cylinder and a mounting method.The offshore fixed structure foundation negative pressure cylinder comprises an upper foundation structural frame and a negative pressure cylinder, the upper foundation structural frame is a truss type structural frame, and the negative pressure cylinder is of an inverted cup type structure with the bottom open and the upper watertight portion; a stand column of the upper foundation structure frame is connected with a supporting stand column of the negative-pressure cylinder in a welded mode, the negative-pressure cylinder breaks soil on the surface layer into a mud-water mixture through high-pressure water injection in the process that the negative-pressure cylinder is installed close to the bottom through a spraying pipe system, the mud-water mixture is sucked and discharged through a pump skid block, and the negative-pressure cylinder can conveniently and continuously penetrate till the top of the cylinder sinks below the seabed mud surface; according to the structure, the hydraulic jetting mode is adopted, the structure is simple, mechanical damage to the negative pressure cylinder structure is avoided, installation and operation are convenient, serious soil plugs in the negative pressure cylinder can be treated, and reliable support is provided for the negative pressure cylinder to penetrate into the deeper position.
本发明公开了一种海上固定式结构物基础负压筒及安装方法，海上固定式结构物基础负压筒，包括上部基础结构架和负压筒，上部基础结构架为桁架型结构架，负压筒为底部敞开且上部水密的倒杯型结构，上部基础结构架的立柱与负压筒的支撑立柱焊接连接，负压筒通过喷冲管系实现负压筒安装近底部过程中通过高压水喷射将表层的土壤破开成泥水混合物，通过泵撬块抽吸排出，便于负压筒继续贯入，直至达到筒顶沉到海床泥面以下，不受冲刷影响，长期稳定的支撑上部的海上风机塔筒或者平台设备等结构载荷，该结构水力喷射方式结构简单，不会对负压筒结构产生机械破损，安装操作方便，能够处理较为严重的负压筒内土塞，为负压筒贯入更深的位置提供可靠支持。
