Abstract

PURPOSE: To obtain a high-head suction device by mounting an air inlet port on a vacuum suction pipe.
CONSTITUTION: From driving a vacuum pump 1 with throttle valves 4,4' controlled moderately, a vacuum suction pipe 3 becomes negative in pressure inward to suck muddy water W through a suction fitting 3a and also a moderate air through air inlet pipes 5,5'. And for the first stage, the muddy water W raises a suction pipe 3 about 10 meters from a muddy water surface W' underground. The air sucked through the air inlet pipes 5,5' is then confined in a bent 3c of the suction pipe 3, and there is left a space free from muddy water in said bent 3c. Since the muddy water has a surface tension, an air zone A and muddy water zones B1, B2 are present independently in the suction pipe 3. A head H of a vacuum tank 2 can be sucked H1 higher than in the case where only the muddy water is full in the suction pipe.
