    La Ligne SNCF N\u00b0 930 000 relie Marseille dans les Bouches-du-Rh\u00f4ne (13) \u00e0 Vintimille en Italie. C’est l’une des principales lignes de chemin de fer du Sud-Est de la France, qui longe sur une grande partie la c\u00f4te m\u00e9diterran\u00e9enne. <\/p>\n

    Le relief difficile de la C\u00f4te d’Azur rend les courbes relativement serr\u00e9es et les vitesses assez basses pour un axe de cette importance. De par ce relief escarp\u00e9 et face aux risques de chutes de blocs rocheux, la SNCF a souhait\u00e9 s\u00e9curiser les installations et les circulations ferroviaires.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Les travaux consistaient \u00e0 installer 3 lignes d’\u00e9crans de protection sur les parois rocheuses situ\u00e9es sur le versant et la tranch\u00e9e d’acc\u00e8s au tunnel de Cap Martin, du Km 245,020 au Km 245,656, afin de s\u00e9curiser les installations et les circulations ferroviaires, face aux risques de chutes de blocs rocheux. <\/p>\n

    Le groupement d’entreprises CAN \/ HYDROKARST a fait appel \u00e0 France Maccaferri qui a fourni ses \u00e9crans pare-bloc RB750 (une ligne de 192m) et RB1500 (deux lignes : une ligne de 70m et une ligne de 120m). <\/p>\n

    Ces \u00e9crans sont en mesure de r\u00e9sister \u00e0 l’impact d’un bloc rocheux de plus de 750 kJ et 1500 kJ. Les \u00e9crans, Certifi\u00e9s CE, ont \u00e9t\u00e9 test\u00e9s selon l\u2019agr\u00e9ment europ\u00e9en EAD340059-00-0106 et sont de Cat\u00e9gorie \u00ab A \u00bb. La distance entre les voies et les \u00e9crans devait \u00eatre minime compte tenu de l\u2019implantation du terrain. Les performances des \u00e9crans Maccaferri en terme d’allongement r\u00e9pondaient parfaitement \u00e0 ces exigences.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
