Abstract

PURPOSE: To accurately throw foundation stones inside of a throw-in area even in the deep water.
CONSTITUTION: A guide 2 is sent to a predetermined position at the sea bottom by partly filling a buoyancy tank 3 after expanding the spaces between ejection pipes 4, 10 and 11 by extending out wire ropes 7, and the buoyancy tank 3 is located at a reguired depth under the sea level by controlling the drawn out length of the wire ropes 7 so as not to prevent novigation of drump ships 25 or the like. On this occasion, sinkers 6 land at the sea bottom so as to prevent the guide 2 from moving sideways. The foundation stones 26 are then thrown inside water flow film formed above required part of boundary of the foundation stone throw-in area at the sea bottom by ejecting the water supplied with a pump 20 as indicated with 4, 10 and 11.
