FIELD: protection of concrete of sewage collectors from corrosion. SUBSTANCE: method of cathode protection of reinforced concrete sewage collectors and pipelines provided with inspection chambers from corrosion includes application of corrosion-resistant coating, provision and maintenance of protective potential on corroded surface, mounting on the concrete surface in its above-water part of metal net which is connected with cathode, and net surface is coated with a layer of conducting mortar, for instance, slag concrete with layer thickness equalling the width of metal net mesh. Longitudinal resistance of conducting layer is determined by the formula. EFFECT: higher efficiency. 3 cl, 4 dwg
