Africa-Press – Congo Brazzaville. <\/strong><\/span>Les pluies diluviennes des dernie\u0300res semaines ont de\u0301grade\u0301 une partie des talus cense\u0301s prote\u0301ger la route nationale 1 (535 km) reliant Pointe-Noire et Brazzaville. Des ouvriers de La Congolaise des routes (LCR) charge\u0301e de la gestion du re\u0301seau routier sont mobilise\u0301s notamment entre Mindouli (Pool) et le Mayombe, pour tenter de retenir les talus. <\/b><\/p>\n

Des terres ou pierres en pentes incline\u0301es, encore appele\u0301es talus, ont e\u0301te\u0301 ame\u0301nage\u0301es lors de la construction de la route pour pouvoir prote\u0301ger la chausse\u0301e. Une bonne partie de la nationale 1 se trouve dans une zone a\u0300 reliefs tre\u0300s accidentels surtout du co\u0302te\u0301 du Mayombe. Les e\u0301quipes de travaux de LCR mettent en place des ouvrages d\u2019arre\u0302t ou de stabilisation des masses de terres ou de roches instables.<\/p>\n

De nombreuses solutions sont de\u0301ploye\u0301es au fil du temps, a explique\u0301 Aime\u0301 Batantou, le chef d\u2019e\u0301quipe de ge\u0301nie civil a\u0300 LCR base\u0301 a\u0300 Mayama (Pool) pour le maintien des talus. \u00ab Nous mettons des sacs de sable pour e\u0301viter l\u2019e\u0301boulement afin de prote\u0301ger la chausse\u0301e (…) C\u2019est une activite\u0301 que l\u2019e\u0301quipe me\u0300ne re\u0301gulie\u0300rement surtout en pe\u0301riode des pluies. Mon e\u0301quipe travaille de Yie\u0301 jusqu\u2019a\u0300 Mindouli, dans le Pool. Une autre e\u0301quipe prend le relais de Mindouli jusque dans le Mayombe \u00bb, a confie\u0301 cet ouvrier.<\/p>\n

Les solutions de protection des talus employe\u0301es par les e\u0301quipes de LCR sont adapte\u0301es selon la nature du danger et du terrain. Il peut s\u2019agir de l\u2019herbe et du semis pour la consolidation des talus, y compris des solutions plus one\u0301reuses comme des murs en pierres et ciment, de grillage pendu ou grillage plaque\u0301… Installe\u0301es sur des falaises et talus rocheux, ces diffe\u0301rentes solutions permettent de retenir les chutes de blocs et le risque d\u2019e\u0301boulement sur la circulation.<\/p>\n

Entreprise concessionnaire de la route nationale, LCR me\u0300ne re\u0301gulie\u0300rement des travaux de re\u0301paration sur les cinq talus pre\u0300s de Mindouli et dans le Mayombe, soit sur environ 128 km. Elle exe\u0301cute aussi des chantiers de re\u0301paration du parapet et du garde-corps, de nettoyage des caniveaux, de construction du fosse\u0301, dans l\u2019optique de la sauvegarde de ce principal re\u0301seau routier du pays.<\/p>\n
