Abstract

PURPOSE: To construct an artificial islet by providing concrete protection walls as the outer block and filling sand inside.
CONSTITUTION: A float 1 provided with a shrunk thin film bag 2 is towed to a predetermined place on the sea and fixed to the sea bed ground B by means of a vertically provided anchor 4. Then, the thin film bag 2 is expanded into a conical cylinder form until it reaches the sea bed ground B, sand 7 is filled in an inner region formed by the thin film bag 2, concrete is then placed into the thin film bag 2, and then water in the sand 7 is discharged. By this, soil pressure is reduced to water pressure to complete a concrete wall A induced with prestress in its circumferential direction.
