An octagonal carbon molding dispersion spinning needle ground rod is provided to prevent damage to dispersion spinning needles attached to an outer side of the ground rod during a laying work under the ground. Middle molding units(506) comprise the third pipe, the fourth spinning needle, and the fifth sealing nut. An upper section is combined to cover an upper opening unit of the third pipe. Each of middle straight line units(609) comprises four of the sixth spinning needles, the seventh spinning needle, and the eighth sealing nut. Each of lower sections comprises four of the ninth spinning needles and the tenth spinning needle. The lower sections formulate a lower-end carbon molding unit which is molded through compression. |
