Abstract

PURPOSE: To automatically adjust the height of a dam by closing or opening a supply or discharge pipeline for fluid by means of a float valve capable of directly operating according to the water level.
CONSTITUTION: Air is supplied through the main air supply pipeline 14 from a blower 13 into a rubber dam 1 so as to erect the dam. When the water level of dam rises, float valves 20 and 23 operate concurrently at a given water level, where the float valve 20 closes an auxiliary air supply pipeline 17 to disconnect a tank 15 with the rubber dam 1, whereas the float valve 23 opens a small diameter air discharge pipeline 24 to lead the rubber dam 1 to the open air. Then, the rubber dam 1 is evacuated through discharge pipes 21 and 24, the height of the dam 1 is gradually lowered, and the water level of the dam 1 is also reduced. When the water level is reduced to a certain level, the float valve 20 opens the pipeline 17 and the float valve 23 closes the pipeline 24. Compressed air is supplied from the tank 15 into the dam 1 and the height of the dam 1 is restored to its original one.
