Offshore platform cable protection pile, pile sinking method and pile sinking device
The invention relates to an offshore platform cable protection pile, a pile sinking method and a pile sinking device.The cable protection pile comprises a cable protection pile pipe, the upper portion of the cable protection pile pipe is fixed to a platform pile leg through a connecting support, and a platform cable clamp is arranged above the cable protection pile pipe; the cable protection pile pipe entering water is fixed with the platform pile leg through an underwater fixing clamp; the cable guide pipe is arranged at the lower part of the cable protection pile pipe; and a cable inlet of the cable guide pipe is arranged below one meter of the mud surface after the seabed is scoured. Influences of cable exposure, suspension and marine environment load are effectively avoided, cable damage is effectively prevented, and huge economic loss caused by the cable damage is avoided. According to the pile sinking device, the pneumatic motor is adopted for cutting and drilling the mud surface after the seabed is scoured, and the technical means of hydraulic jetting is assisted, so that pile sinking construction beside a platform pile leg becomes possible, and the safety of a submarine cable at the end close to the platform is protected.
本发明是一种海上平台电缆保护桩及沉桩方法和沉桩装置，电缆保护桩包括电缆保护桩管，电缆保护桩管的上部通过连接撑固定在平台桩腿上面，电缆保护桩管的上方设有平台电缆卡子，入水后的电缆保护桩管使用水下固定卡与平台桩腿固定在一起；电缆导向管设在电缆保护桩管的下部，电缆导向管的电缆入口设在海底冲刷后泥面1米以下。有效避免了电缆裸露、悬空和海洋环境荷载的影响，有效防止电缆的损坏并且避免由此引发的巨额经济损失。本发明中的沉桩装置采用气动马达对海底冲刷后泥面进行切削和钻孔，辅助水力喷冲的技术手段，使在平台桩腿旁的沉桩施工成为可能，保护了近平台端海底电缆的安全。
