FIELD: corrosion protection. SUBSTANCE: invention relates to protection of underground structures and pipelines against electrochemical corrosion. Point of invention consists in that, in a deep anodic grounding conductor containing two concentrically arranged steel pipes, space between the latter is filled with coke fines and, to inner pipe along all its working part outside, steel members are fastened, which are made in the form of balls embracing the pipe. EFFECT: increased service life of grounding conductor due to uniform flowing down of electrical current. 1 dwg
