METHOD FOR REMOVING AND INSERTING SEDIMENTS, SLICKS OR OTHER MATERIALS FROM A OR ON A WATER BOTTOM AND DEVICE FOR IMPLEMENTING THE METHOD

摘要

A method of removing and placing sediments, sludge or other materials from/on the bed of a stretch of water, in which a hood-like receiving device is lowered onto the bed of the stretch of water and during the removal is pressed at least partly into the bed while material to be removed is enclosed, whereupon the water is displaced out of the receiving device and the enclosed material is removed from the bed of the stretch of water, is to bring about in particular better separation of the material to be removed, from the free water and is to be less complicated. To this end, the receiving device is closed at the bottom after being pressed into the bed and, to remove the enclosed material, is raised with the latter. On the other hand, during the placing of materials, the receiving device is brought through the water together with the enclosed material onto the bed of the stretch of water. After the bottom closure plate (11) is opened, the material can be pressed out of the receiving device by means of the pressure plate (6) and be deposited compactly on the bottom. IMAGE
