    En abril de 2013, antes del reinicio de las obras de recuperaci\u00f3n de la zona colapsada del 1er evento (febrero del 2011), se produjo un deslizamiento pr\u00f3ximo al portal R\u00edmac del T\u00fanel de San Mart\u00edn; que invadi\u00f3 completamente la calzada de este t\u00fanel.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Estabilizaci\u00f3n del talud con pernos helicoidales de 32mm de longitudes variable de 4 a 12m, instalaci\u00f3n de mallas de alta resistencia 8x10x3mm, cable de 9\/16\u201d para el refuerzo interno del talud y barreras din\u00e1micas de 750 KJ. La distribuci\u00f3n de los pernos fue de 1.90 x 1.90 m, a tres bolillos.<\/p>\n

    Las barreras din\u00e1micas corresponden a la 1ra etapa y fue instalado en toda la corona del talud.<\/p>\n

    De esta manera, se configur\u00f3 un sistema de control de ca\u00edda de rocas y la estabilizaci\u00f3n del talud en el sector de sostenimiento y deslizamiento.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
