Title (EN) METHOD FOR TREATMENT OF DREDGED MATERIALS TO FORM A STRUCTURAL FILL
(FR) PROCEDE DE TRAITEMENT DE DEBLAIS DE DRAGAGE POUR FORMER UN REMBLAI
Abstract:
(EN) The present invention disclosed herein comprises a process for treating materials (28) dredged from a waterway, such as a harbor or channel, and forming a mixture (69) suitable for beneficial re-use as a structural fill. The dredged materials (28) may be placed in a treatment vessel (26) which transports 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 fixaton, stabilization and solification 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 to form the structural fill.
(FR) La présente invention concerne un procédé de traitement de déblais (28) dragués dans un cours d'eau, par exemple un port ou un canal. Ce procédé consiste ensuite à former un mélange (69), conçu pour être réutilisé avantageusement en tant que remblai. Ces déblais de dragage (28) peuvent être placés dans une cuve de traitement (26), qui permet de faire passer ces déblais de dragage (28) par plusieurs étapes de traitement, notamment une étape de déshydratation, une étape d'élimination des débris, une étape de fixation, de stabilisation, et de solidification, une étape de durcissement, pour finir par une étape de déchargement. L'étape de fixation, de stabilisation, et de solidification consiste à ajouter un additif de type ciment, par exemple un ciment Portland, ainsi que d'autres additifs destinés à stabiliser lesdits déblais de dragage par fixation et solidification chimiques, afin de former le remblai.
