The invention refers to protective pieces, especially for protecting the lower area of the posts that hold up, for instance, the overhead power cables of a railway against undesired actions that would erode its exterior surface. If these posts are made of metal, the aforementioned erosion may affect the layers of paint that protect against corrosion, as well as the outer layers that give them colour and cover them. Another object of the invention is the procedure for the placement of these pieces on the lower part of said posts in the ballast area, in the laying of railway lines, for which these pieces are designed, as well as other applications outside of the field of railways, for the simple protection of any type of post, whether placed inside or outside of urban areas. |
