    El pasado mi\u00e9rcoles 3 de abril, un desprendimiento de tierras y rocas afect\u00f3 la carretera N-260 a la altura del P.K. 288+950, en la localidad de Baro, lo que oblig\u00f3 al cierre temporal de la v\u00eda. El talud afectado contaba con protecci\u00f3n parcial mediante una malla de triple torsi\u00f3n y una red de cable con bulones. Sin embargo, en la zona de origen del desprendimiento se detectaron grietas y bloques inestables, lo que representa un riesgo significativo para la seguridad de los usuarios de la carretera. Adem\u00e1s, los desprendimientos recurrentes en este tramo son provocados principalmente por episodios de precipitaciones intensas, ya sea de agua o nieve.<\/p>\n

    <\/p>\n

    La geolog\u00eda de la ladera est\u00e1 compuesta por pizarras y calizas del Dev\u00f3nico en su base, dep\u00f3sitos granulares de terrazas fluviales en los pies de ladera, la formaci\u00f3n Malpas, y bloques err\u00e1ticos del Buntsandstein. Esta combinaci\u00f3n de materiales presenta una alta susceptibilidad a la erosi\u00f3n, especialmente en eventos de lluvias intensas, lo que agrava el riesgo de nuevos desprendimientos.<\/p>\n

    La Direcci\u00f3n General de Carreteras determin\u00f3 la instalaci\u00f3n de sistemas de contenci\u00f3n flexible para estabilizar el talud inestable. La soluci\u00f3n adoptada consiste en la colocaci\u00f3n de una membrana Steelgrid HR30, galvanizada con aleaci\u00f3n GalMac C3 (Zn90-Al10%, clase A), que garantiza una durabilidad superior a 50 a\u00f1os en entornos de corrosividad C3. Esta membrana se fija al talud mediante bulones, diferenciando dos \u00e1reas de intervenci\u00f3n: en la zona inferior, se utilizaron anclajes de barra de acero Gewi de \u00d8 32 mm, mientras que en la zona superior los anclajes tienen un di\u00e1metro de 40 mm.<\/p>\n

    <\/p>\n

    El sistema Steelgrid HR30 destaca por su excepcional resistencia a la tracci\u00f3n de 180 kN\/m y una resistencia al punzonamiento de 155 kN, proporcionando una soluci\u00f3n duradera y eficaz.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
