Abstract

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.
