Abstract

The weir has a metal flap which has an air container and is hinged to a threshold guide, which is arranged on the floor of the waterway to be dammed. Specifically, there are holes (9) in the metal flap (5 or 23) pipes (11) pass from these holes and have an elbow (12) in the region of the threshold guide. There is also a device to allow air to enter into the air container of the metal flap. The air container (7) is in the form of an inverted glass, which has ventilation valves (8) at the top end. More specifically, there is a plate (24) in the air container (7) to divide this container into two parts. One part (25) has an outward opening large hole (27) and the other part (26) has an outlet air valve (26').
