Abstract
There is disclosed a cathodic protection system of reinforced concrete structures with discrete anodes obtained starting from a corrugated planar substrate welded to a longitudinal current collector. The anodes of the invention are particularly suitable for being installed rolled in cylinders, with their axis parallel to the current collectors, positioned inside holes made in the concrete of the structure to be protected.
Claims19
Cathodic protection system of reinforced concrete structure comprising:
- a metal reinforcement embedded in concrete, comprising a multiplicity of anodes, each of the anodes comprising a corrugated metal planar substrate welded to a current collector, the anodes being forcedly housed in a multiplicity of openings obtained in the concrete.
Method for the installation of a cathodic protection system in a reinforced concrete structure comprising a metal reinforcement embedded in concrete, comprising:
- obtaining a multiplicity of holes in the concrete;
- forcedly housing inside each of said holes an anode comprising a corrugated metal planar substrate welded to a current collector and folded in a cylindrical position with axis parallel to a current collector;
- and
- fixing the anodes inside the holes with cement mortar applied by casting or by spraying.
Method for the installation of a cathodic protection system in a reinforced concrete structure comprising a metal reinforcement embedded in concrete, comprising:
- obtaining a multiplicity of holes in the concrete;
- forcedly housing inside each of said holes a stiff plastic guide tube;
- inserting in each of said tubes an anode comprising a corrugated metal planar substrate welded to a current collector and folded in a cylindrical position with axis parallel to a current collector;
- extracting said guide tubes leaving behind the anodes;
- and
- fixing the anodes inside the holes with cement mortar applied by casting or by spraying.
Method for the cathodic protection of a reinforced concrete structure comprising:
- providing a cathodic protection system for the reinforced concrete structure comprising a metal reinforcement embedded in concrete, comprising a multiplicity of anodes, each of the anodes comprising a corrugated metal planar substrate welded to a current collector, the anodes being forcedly housed in a multiplicity of openings obtained in the concrete;
- and
- applying an anodic potential to the anodes of the cathodic protection system.
