The invention relates to a device for depositing material under water. The device is provided with an elongated chute, which is connected near its upper end to a supporting structure at least partially located above the water surface. A frame is provided near the bottom end of said chute, which frame is provided with a tube section forming the bottom end of said chute, and with propelling means, by which the frame and the bottom end of the chute can be moved in directions perpendicularly to each other. The frame is coupled, using spring means, to a supporting member secured to the bottom end of said chute, said supporting member being provided with a second tube section, which extends into the first tube section secured to the frame, in such a manner that the two tube sections are telescopically movable in the longitudinal direction of the chute with respect to each other.
