In-vivo cable threading method

The invention relates to the technical field of offshore wind power construction, and discloses an in-vivo cable threading method. The in-vivo cable threading method comprises the steps that sand-embedded epoxy steel stranded wires are manufactured into a stranded wire bundle, the stranded wire bundle comprises a preset number of sand-embedded epoxy steel stranded wires, and a connector is arranged at one end of the stranded wire bundle; a steering wheel is arranged at the end, away from the threading opening, of the hole channel, and a traction rope penetrates into the hole channel from the threading opening and penetrates out of the hole channel from the threading opening after being wound around the steering wheel; and connecting one end of a traction rope with the connector, and dragging the other end of the traction rope, so that the stranded wire harness is arranged in the hole channel. The connector is arranged at one end of the stranded wire harness, the steering wheel is arranged at the end, away fro
