Method for a compact support and protection assembly for all types of cable. The method makes it possible to avoid agglutination of effluents at the upper part of the protection, by virtue of its geometry, and provides protection against pricking due to compact bodies. It is constituted by a galvanised sheet metal profile with a thickness of 1 mm 1, a PVC tube with an external diameter of 45 mm 2 and by a needle made of galvanised wire 3. Its fastening to the bricked concrete walls is done by means of 36 mm long nails 4 with rawl plugs 5. This method according to the invention is in particular intended for drains and outfalls. <IMAGE>
