Способ катодной защиты от коррозии подземных металлических сооружений, преимущественно магистральных трубопроводов, включающий катодную поляризацию сооружения током, поступающим от источника тока на сооружение через почвенный электролит с анодного заземления, соединенного с положительным полюсом источника и возвращающимся с сооружения на отрицательный полюс источника по электрическому дренажу, соединенному с сооружением в проектной точке дренажа, отличающийся тем, что, с целью повышения эффективности путем устранения коррозии, обусловленной анизотропией электрических свойств окружающей сооружение среды, после катодной поляризации сооружения на нем определяют участки с локальными очагами коррозии, устраивают на этих участках дополнительные точки дренажа и соединяют их с отрицательным полюсом источника или с участками с более отрицательной величиной поляризационного потенциала, расположенными в направлении проектной точки дренажа.Method of cathodic protection against corrosion of underground metal structures, mainly main pipelines, including cathodic polarization of the structure by current coming from the current source to the structure through soil electrolyte from the anode ground connected to the positive pole of the source and returning from the structure to the negative pole of the source by electrical drainage connected with construction at the design point of drainage, characterized in that, in order to increase efficiency by eliminating corrosion, by the anisotropy of the electrical properties of the environment surrounding the structure, after cathodic polarization of the structure, areas with local corrosion centers are determined on it, additional drainage points are arranged on these sites and connected to the negative pole of the source or to sites with a more negative polarization potential located in the direction of the design point drainage.
