Contexte sp\u00e9cifique du chantier de La Rochaille <\/strong><\/p>\n\n

Le passage de la Rochaille, sur la RD 900, qui relie la France et l’Italie par la vall\u00e9e de l’Ubaye dans les Alpes-de-Haute-Provence constitue un des axes routiers<\/strong> des plus sensible<\/strong> en termes de s\u00e9curisation<\/strong>. C’est un axe majeur<\/strong> de liaison entre la France et l\u2019Italie par le col de Larche. Maccaferri<\/strong> a donc propos\u00e9 son large choix de solutions<\/strong> dans le domaine des protections <\/strong>contre les chutes de blocs<\/strong> et a pu installer pour la premi\u00e8re fois en France, le syst\u00e8me d’alerte HelloMac GEO<\/strong>.<\/p><\/div><\/div><\/div>

D\u00e9ploiement du syst\u00e8me d\u2019alerte HelloMac GEO, premier chantier en France<\/strong><\/p>\n\n

<\/div>\n\n

Le chantier de La Rochaille marque une \u00e9tape d\u00e9cisive en devenant le premier en France \u00e0 int\u00e9grer le syst\u00e8me HelloMac GEO.<\/p>\n\n

Cette technologie novatrice<\/strong> a \u00e9t\u00e9 d\u00e9ploy\u00e9e sur les \u00e9crans fournis <\/strong>par France Maccaferri<\/strong>, ainsi que sur ceux qui \u00e9taient d\u00e9j\u00e0 en place<\/strong> depuis 2019. En cas d’impact, une s\u00e9rie de niveaux d’alerte<\/strong> est d\u00e9clench\u00e9e, permettant une r\u00e9action rapide<\/strong> et adapt\u00e9e<\/strong> aux menaces.<\/p>\n\n

<\/div>\n\n

Cette innovation technologique r\u00e9duit consid\u00e9rablement le temps de r\u00e9ponse et accro\u00eet la s\u00e9curit\u00e9<\/strong> sur la route de La Rochaille.<\/p><\/div>\n\n

Le syst\u00e8me d\u2019alerte mis en place sur le chantier La Rochaille<\/strong><\/p>\n\n

Le syst\u00e8me a \u00e9t\u00e9 calibr\u00e9 par les techniciens de Maccaferri afin de d\u00e9tecter<\/strong>, selon le positionnement de la ligne d\u2019\u00e9cran sur le versant, un possible impact<\/strong> au MEL (\u00e9nergie ultime) et\/ou au SEL (\u00e9nergie de service).<\/p><\/div><\/div><\/div>

<\/div>
\"\"<\/figure><\/div>\n\n
<\/div>\n\n

Les HelloMac GEO, directement install\u00e9s<\/strong> sur les structures de protection passives<\/strong>, sont connect\u00e9s via radio<\/strong> \u00e0 2 centrales d\u2019acquisition (Hubir) qui permettent, en cas d\u2019impact, d\u2019actionner des signaux d\u2019alerte<\/strong> directement positionn\u00e9s sur la route (feux, panneaux de signalisation et sir\u00e8ne), ainsi que d\u2019envoyer un message directement aux personnels en charge de la gestion et entretien et s\u00e9curit\u00e9 de la route, via une application directement sur smartphone.<\/p>\n\n

\u00c9tant donn\u00e9 la position g\u00e9ographique du site et la difficult\u00e9 du r\u00e9seau t\u00e9l\u00e9phonique, les centrales Hubir<\/strong> communiquent vers un serveur central par satellite<\/strong>.<\/p><\/div><\/div><\/div>

    La s\u00e9curisation du passage de la Rochaille est un d\u00e9fi complexe<\/strong>, mais vital. Ce projet, qui vise \u00e0 prot\u00e9ger<\/strong> les voyageurs, les habitants locaux, ainsi qu’\u00e0 maintenir l’activit\u00e9 \u00e9conomique et touristique, est une d\u00e9monstration de l’ing\u00e9nierie moderne et de l’innovation technologique<\/strong>.<\/p>\n\n

    La combinaison de structures de protection avanc\u00e9es<\/strong>, de dispositifs de d\u00e9tection sophistiqu\u00e9s<\/strong> et d’une planification minutieuse<\/strong> marque une \u00e9tape importante dans l’assurance de la s\u00e9curit\u00e9<\/strong> sur cette route strat\u00e9gique<\/strong> reliant la France et l’Italie.<\/p>\n\n

    En effet, Maccaferri a fourni diff\u00e9rentes barri\u00e8res dynamiques (de 750kJ \u00e0 5000kJ<\/strong>), des parades actives<\/strong> en grillages, filets et ancrages mais aussi des parades passives<\/strong> tels que des avaloirs<\/strong> con\u00e7us <\/strong>sp\u00e9cialement pour ce chantier<\/strong>.<\/p><\/div><\/div><\/div>
