Method for protecting novel anti-drop submarine cable

A method for protecting a novel anti-drop submarine cable, the method achieving the protection of the submarine cable by a submarine cable protection device, the submarine cable protection device comprises:

• a traction assembly;
• a standard bending protection section;
• and
• a protection reinforcement section, the method includes:
• connecting and assembling the traction assembly, the standard bending protection section and the protection reinforcement section in sequence to form the submarine cable protection device, and enabling a submarine cable to pass through the submarine cable protection device to complete the assembly;
• connecting a traction rope at a front end of the traction assembly to a reserved traction rope pre-installed in a single pile foundation, and turning on a traction device for the single pile foundation to enable the submarine cable and the submarine cable protection device to pass through a reserved hole of the single pile foundation;
• continuing to move the submarine cable protection device and the submarine cable forward by the traction device until the traction rope is lifted by a force and cannot move forward, then enabling a retaining ring at a rear end of the protection reinforcement section to abut against an outer wall of the reserved hole, and installing the traction rope on the single pile foundation by shackles;
• and
• continuing to pull the reserved traction rope to pull the submarine cable to a proper length, and installing and fixing the submarine cable to a submarine cable installation base.
