Abstract

PURPOSE: To voluntarily adjust the height of a fense underwater by a method wherein an air chamber to control a buoyancy is connected to a fense having an anchor at one end and the buoyant body at the other end.
CONSTITUTION: A case when a fense sinks is made an (a) and a case when the fense floats is made a (b). The fense is constituted with the topmost rigid buoyant body 3 (such as a foamable styrene buoyant body), an air chamber 4, a flexible mambrane 6 (such as a rubber cloth),a rope 7 (such as a wire rope and chains) and an anchor 8. The air chamber 4 is connected to an air pouring and exhaust pump on land through a rubber hose 5 and air is poured in and exhausted out of the air chamber 4 by means of this pump. With this, the buoyancy of the fense can be controlled.
