    • PROBLEM TO BE SOLVED: To provide structurally-simple equipment for preventing diffusion of contamination, which can properly promote sedimentation of a contamination component depending on a water flow and the condition of construction work, and a method for preventing the diffusion of the contamination.
      SOLUTION: The flow containing the contamination component 31 directed outward from a construction sea area 7 has its direction changed to a vertical one at a collision with a rotary plate 11, while having its direction set as a horizontal one until the flow goes beyond a contamination diffusion prevention membrane 9. Thus, the contamination component 31 is sedimented near the construction sea area 7, suppressing the outflow of the contamination component to an area far from the construction sea area 7. The rotary plate 11 is completely opened for the flow directed inward from the outside of the construction sea area 7. This makes the rotary plate 11 hardly undergo the resistance of the flow. Consequently, the rotary plate 11 is pushed by the flow, so that the contamination diffusion prevention membrane 9 can be restrained from being curled up.
