#CMT# #/CMT# The aqueduct (1) has a collector (11) connected to a fresh water channel (12) by a gate (13) and to an evacuation duct (15) by another gate (14). An inlet of a flood duct (16) is equipped with a grid (17) for discharging excess water from the river to another evacuation duct (20) when the level of the river attains upper limit. The flood duct is connected to the latter evacuation duct, and a bypass duct (8) and an outlet duct (10) are branched to the collector. #CMT#USE : #/CMT# Aqueduct for collecting and canalizing agitating water during overflow of river. #CMT#ADVANTAGE : #/CMT# The aqueduct is simple and easy to operate and inexpensive. The inlet of the flood duct is equipped with the grid for discharging excess water from the river to the evacuation duct when the level of the river attains upper limit, thus avoiding chance of flood. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a transversal sectional view of an aqueduct. 1 : Aqueduct 8 : Bypass duct 10 : Outlet duct 11 : Collector 12 : Fresh water channel 13, 14 : Gates 15, 20 : Evacuation ducts 16 : Flood duct 17 : Grid. |
