Abstract
An improved method for underwater reclamation is disclosed. Dredged mud sent under pressure by an earth and sand conveying device is treated with solidifying material, and before it is solidified, it is directly fed to an underwater reclaiming apparatus. The treated mud is fed through a discharge port of the underwater reclaiming apparatus, while the discharge port is always maintained embedded at a constant depth in a previously deposited underwater reclamation mud layer at the bottom of the water. An apparatus for underwater reclamation that is suitable for practicing the improved method is also disclosed.
