PROBLEM TO BE SOLVED: To prevent aquatic creatures from adhering to a submerged structure by installing at least two sets of submerged structures in parallel and equipping a device cutting off water and draining water, in the submerged structures. SOLUTION: In this adhesion proof device 1 of creatures, water channels 9 are branched in parallel by a median strip 8, and two submerged structures 2a, 2b are installed respectively in parallel Some of the submerged structure 2a, 2b are sluice gate, gate, screen, etc. These are surrounded and arranged to make it possible to drain. An upstream partition 3 and a downstream partition 5 cutting off the water channel are changed over to positions of 3a, 5a respectively and the zone partitioned by the upstream and downstream partitions 3a, 5a is drained by a pump 4b. In this way, the submerged structure 2b is exposed in the air and operated. Accordingly, adhesion of aquatic creatures can be prevented by alternately draining water from the submerged structure and exposing them in the air.
