Title (EN) SOLIDIFICATION AND STABILIZATION OF DREDGED MATERIALS
(FR) SOLIDIFICATION ET STABILISATION DE MATERIAUX DE DRAGAGE
Abstract:
(EN) The present invention disclosed herein comprises a process for fixation, stabilization and solidification of materials (28) dredged from a waterway, such as a harbor or channel, within a treatment vessel (26). The treatment vessel (26) is used to transport the dredged materials (28) through a plurality of processing stages including a dewatering stage, a debris removal stage, a fixation, stabilization and solidification stage, a curing stage, and an offloading stage. The fixation, stabilization and solidification stage involves adding a cement type additive such as Portland Cement along with other additives which stabilize the dredged materials by chemical fixation and solidification.
(FR) La présente invention se rapporte à un procédé de fixation, de stabilisation et de solidification de matériaux (28) issus du dragage d'une voie navigable, telle qu'un port ou un canal, et ce au sein d'une embarcation de traitement (26). Ladite embarcation de traitement (26) est utilisée pour faire subir aux matériaux dragués (28) une série d'étapes de traitement telles qu'une étape de déshydratation, une étape d'extraction des débris, une étape de fixation, stabilisation et solidification, une étape de durcissement et une étape de déchargement. L'étape de fixation, stabilisation et solidification consiste en l'ajout d'un additif de type ciment, tel que le ciment Portland, et d'autres additifs qui stabilisent les matériaux issus du dragage par fixation et solidification chimique.
