The invention discloses a spiral pipe cable conveying method, and belongs to the technical field of pipe cables. The spiral pipe cable conveying method is finished by dint of a cable conveying device;the cable conveying device comprises a horizontal drilling machine; a cable is fixedly connected with a drill rod of the horizontal drilling machine; spiral blades sleeve and are fixed on the cable;the spiral blades comprise roots, and tips fixedly connected with the roots; the cross sections of the tips are circular; a ratio of thicknesses L of the roots to diameters D of the tips is 1: (1-1.2); the cable is driven by the horizontal drilling machine to form a spiral pipe cable conveying structure; the cable conveying structure comprises a support frames with a walking mechanism and arrangedbetween the drill rod and a pipe, and a cable groove formed in the support frame; a shaft roller for supporting the cable is arranged in the cable groove; the surface of a roller body of the shaft roller is in an arc groove form; and based on the structure, in the process of spirally conveying the cable to the other end of the pipe by dint of the horizontal drilling machine, blockage particles are finally charged in the pipe. The method can easily, quickly and perfectly convey the cable and the blockage particles in place at the same time.
