Abstract

PURPOSE: To prevent a drain pit from overflowing in a case where an accident has occured when a water level is being pushed down, by pushing the water level to a certain level for the time being, closing an air feeding valve at that point, and opening an air discharging valve for a prescribed period.
CONSTITUTION: In a case where an accident has occured when a water surface is being pushed down, the air feeding valve 6 is kept open to continue feeding of air to push the water surface down to a water level WL3 for the time being, and at this point the air feeding valve 6 is closed, and the air discharging valve 8 is kept open until the water surface raises from the water level WL3 and the casing 5 is filled. Thus, as unnecessary water would not flow into the drain pit 12, the drain pit 12 is prevented from overflowing.
