INTAKE WORKS PARTICULARLY DRAWING-OFF FROM IRRIGATION CANALS

摘要

The water intake (2) has a collecting space (16) and a connecting section from the water base bed to the collecting chamber (16). The essence is that, in terms of the water flow direction (b), a bottom-level foreground (15) above its bottom level is formed in front of the collecting area (16), the water inlet, such as the water-inlet (1) inlet (10) having a larger cross-section than the collecting space ( 16) connector inlet (50). Thisthe lower edge of the latter is positioned higher than the lower edge of the inlet (10), which is higher than the bottom of the water base, such as the stream (1). The front (15) is delimited by an external filter grid (17) from the water base and an internal filter grid (18) from the collecting space (16). In front of the inlet (10), a floating body (20) is formed as a floating body in the area of the water surface (21).
