La explanada norte del puerto exterior de A Coru\u00f1a cuenta con un talud rocoso de inclinaci\u00f3n subvertical, fruto de los desmontes que se realizaron para ubicar las instalaciones. As\u00ed pues, el talud sufr\u00eda desprendimientos de rocas que pon\u00edan en riesgo las instalaciones a construir. Al tener unas grandes dimensiones (altura entre 40 y 60 metros), cubrir todo el talud con un sistema de contenci\u00f3n flexible no ser\u00eda viable econ\u00f3micamente.<\/p>\n

Por otro lado, el ambiente es de una gran corrosividad atmosf\u00e9rica, por el efecto de la niebla salina del mar. Por ello, se deb\u00eda recurrir a soluciones con una durabilidad<\/p>\n

adecuada en ambientes muy agresivos (ambiente CX conforme la normativa EN 10.223-3).<\/p>\n

La Autoridad Portuaria encarg\u00f3 un proyecto a la ingenier\u00eda Antea Iberolatam para la consolidaci\u00f3n definitiva del talud rocoso, y as\u00ed posibilitar la actividad de Repsol en dichos muelles de forma segura.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

A fin de proteger las instalaciones contra los desprendimientos, se propuso y dise\u00f1\u00f3 una soluci\u00f3n mixta con un sistema de contenci\u00f3n flexible en el primer tramo del<\/p>\n

talud de alta rigidez, y muy alta durabilidad.<\/p>\n

Dicho sistema est\u00e1 formado por:<\/p>\n

– Membrana Steelgrid HR 30 Polimac\u00ae. Este sistema cuenta con una mayor resistencia y rigidez (deformaci\u00f3n ante una determinada fuerza) que las mallas de doble trenzado<\/p>\n

tradicionales, adem\u00e1s de tener 120 a\u00f1os de durabilidad en ambiente CX conforme a la norma UNE EN 10.223-3.<\/p>\n

– Cuadr\u00edcula de bulones Gewi \u00d828 para adosar la membrana al talud y coser las discontinuidades del macizo rocoso.<\/p>\n

– Cables horizontales con recubrimiento Polimac para adosar la membrana al talud.<\/p>\n

– Accesorios de uni\u00f3n y sujetacables en acero inoxidable.<\/p>\n

Adem\u00e1s, se instalaron dos sistemas pasivos (barreras din\u00e1micas). La primera barrera RB 750 Plus situada en la primera berma, y la segunda barrera RB 100 Plus en el pie<\/p>\n

del talud para proteger las conducciones que est\u00e1n situadas al pie de la pared rocosa. Ambas barreras cuentan con galvanizado reforzada para ambientes agresivos.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>","protected":false},"excerpt":{"rendered":"
