Le site a subi un important \u00e9boulement en janvier 2014, ayant donn\u00e9 lieu \u00e0 des travaux de mise en s\u00e9curit\u00e9 (minages, pose de grillages et filets pendus, confortements, pose d\u2019\u00e9crans pare-blocs\u2026). Le pr\u00e9sent march\u00e9 traite de la derni\u00e8re phase de s\u00e9curisation de la zone concern\u00e9e par l\u2019\u00e9boulement, qui surplombe des habitations ainsi qu\u2019une zone d\u2019activit\u00e9. Il porte sur la construction d\u2019un merlon de protection contre les \u00e9boulements rocheux, au pied de la falaise de Bon Voyage \u00e0 Nice, sur la plateforme de l\u2019ancienne casse automobile – SCI La Roseraie. Les travaux sont int\u00e9gr\u00e9s dans un site encaiss\u00e9 dont l\u2019unique acc\u00e8s ne peut se faire qu\u2019en traversant une voie ferr\u00e9e. <\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

A la demande de la soci\u00e9t\u00e9 Garelli, la soci\u00e9t\u00e9 France MACCAFERRI a r\u00e9alis\u00e9 une \u00e9tude portant sur la r\u00e9alisation d\u2019un merlon pare-bloc par une technique de remblai renforc\u00e9 de type Terramesh Min\u00e9ral. C’est une solution avec parement amont en pneusol et un parement aval en Terramesh min\u00e9ral qui a \u00e9t\u00e9 retenue. La soci\u00e9t\u00e9 Maccaferri a r\u00e9alis\u00e9 un dimensionnement ad hoc de la structure en phase d\u2019ex\u00e9cution. Le Terramesh min\u00e9ral consiste en un parement min\u00e9ral qui se prolonge par une nappe de grillage dans le remblai. Le parement est constitu\u00e9 d’un grillage en double torsion certifi\u00e9 NF Acier rev\u00eatu de polym\u00e8re et un panneau \u00e9l\u00e9ctrosoud\u00e9s de fa\u00e7ade. Les structures sont pr\u00e9-assembl\u00e9es en usine lors de la fabrication, ce qui permet une mise en \u0153uvre plus rapide. La nappe de renfort en grillage double torsion assure le renfort horizontal dans le remblai et effectue un retour au parement pour assurer la stabilit\u00e9 locale du massif.Des g\u00e9ogrilles de renforcement Paragrid 100 ont \u00e9t\u00e9 ins\u00e9r\u00e9es dans le remblai en compl\u00e9ment des nappes de grillage. Le treillis soud\u00e9 de maille 50X100 est agraf\u00e9 au grillage en face externe. Des b\u00e9quilles et des \u00e9triers compl\u00e8tent la structure pour assurer la tenue du syst\u00e8me durant la phase de montage. Cette solution pr\u00e9sente une durabilit\u00e9 et une r\u00e9sistance \u00e0 la corrosion tr\u00e8s \u00e9lev\u00e9es gr\u00e2ce au grillage plastifi\u00e9 qui a une dur\u00e9e de vie de 120 ans selon la norme NF EN 10223-3. La mise en \u0153uvre a a \u00e9t\u00e9 r\u00e9alis\u00e9e par les \u00e9quipes exp\u00e9riment\u00e9es de Maccaferri.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
