FIELD: underground works.
SUBSTANCE: invention relates to protecting underground pipelines from electrochemical corrosion. The method is characterized in that a steel screw pile is formed without an electrically insulating coating, consists of a tubular trunk and a nozzle which is inseparably connected thereto and is provided with at least one blade and/or with at least one multi-twisted spiral, at least one anodic earth electrode is placed in the tubular barrel and the free space in the tubular barrel is filled with an electrically conductive composition.
EFFECT: increased reliability of the method for installing anodic earth electrode by reducing the number of operations, dispensing with complex mechanical constructions and ensuring possibility of mounting earth electrodes without the use of heavy specialized equipment.
