Abstract
PURPOSE: To prevent underwater flocky bodies etc. from flowing in by a method wherein by using a fense having an air chamber which can control buoyancy, the buoyancy of this air chamber is controlled and the fense is extended and spread at an optional height underwater.
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 a topmost rigid buoyant body 3 of such as a foamable styrene buoyant material, an air chamber 4, a flexible membrane 6 including a rubber cloth, a rope 7 including wire ropes or chains, and an anchor 8, etc. The air chamber 4 is connected to an air pouring and enhausting pump on the land through a rubber hose 5 and the underwater buoyancy of the fense is controlled by means of pouring and exhausting of gas in the air chamber 4 through that pump. With this, the underwater height of the fense is adjusted and the underwater flocky bodies etc. in a different state according to the season can be prevented from flowing into the intake port.
