Abstract
To reduce the shearing resistance at the surfaces of the diaphragm, and to decrease the buoyancy force, both of which greatly hamper the positioning of diaphragms or thin sheets in slotted wall suspensions, air bubbles are introduced at the bottom end of the diaphragm during the positioning process. These air bubbles ascend along the vertical surfaces of the diaphragm.
