The invention provides an anticorrosion method for an annular concrete pole steel plate ring. The anticorrosion method comprises the steps that 1, an original coating of the annular concrete pole steel plate ring is removed, and rust is removed; 2, priming paint is applied twice; 3, the two ends are enclosed, after the priming paint in the step 2 is dry, epoxy resin, exterior wall putty powder and dimethylbenzene are prepared into paste to be smeared to a gap formed in the connecting portion of the steel plate ring and a concrete pole, compacting and tamping are conducted, the top and the bottom are each covered with 2-5 cm of the paste, drying is conducted, and then polishing is conducted; 4, the portions, 30 cm above and below the steel plate ring, of a concrete pole body are enclosed, wherein an enclosing agent is prepared from a concrete adhesive, exterior wall latex paint and putty powder by adding water and is applied twice; 5, finish paint is applied, wherein the finish paint is applied on the priming paint twice. By using the method to repair the steel plate ring, the anticorrosion life can be effectively prolonged, and the effect that the steel plate ring does not need to be maintained in ten years can be achieved; after the coating is failed, the condition can be found by line inspection personnel in time, further corrosion of the steel plate ring is avoided, and the safety of an electric transmission line is guaranteed.
