Dans le cadre de la protection de la CNPE (centrale nucl\u00e9aire de production d\u2019\u00e9lectricit\u00e9) du Tricastin, suite aux directives li\u00e9es au retour d\u2019exp\u00e9rience du Blayais, EDF a pr\u00e9vu un d\u00e9versoir de s\u00e9curit\u00e9 en amont de la centrale. Ce d\u00e9versoir lat\u00e9ral au canal doit pallier la potentielle mont\u00e9e des eaux due \u00e0 deux ph\u00e9nom\u00e8nes conjugu\u00e9s d\u2019une crue mill\u00e9nale major\u00e9e et un arr\u00eat de l\u2019usine en aval.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

La solution technique retenue consiste en un abaissement de l\u2019arase sup\u00e9rieur de la digue, pour cr\u00e9er une zone localis\u00e9e de surverse. C\u00f4t\u00e9 terre, la digue est prot\u00e9g\u00e9e de l\u2019\u00e9rosion des \u00e9coulements, par une carapace de Matelas Reno (structure plate en grillage double torsion certifi\u00e9 NF Acier). Ils sont constitu\u00e9s d\u2019une nappe continue dormant le fond et les diaphragmes, ce qui permet \u00e0 la structure de ne pas se coucher sous le poids des pierres lors du remplissage. Les eaux sont ensuite \u00e9vacu\u00e9es par une chenal de fuite \u00e9galement prot\u00e9g\u00e9 par les matelas Reno.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
