ABSTRACT:
A weir construction has a weir gate which is tiltable around an axis suspended in a canal section above the bottom thereof, whereby the axis is situated between, and at a distance from, the lower and the upper edge of the weir gate closer to the lower edge of the weir gate than to the upper edge thereof, which weir gate cooperates with a floating counterweight for opening and closing thereof by rotation around the axis. In order to obtain an improved sealing of the weir gate and the canal section, a flexible seal strip is provided between the lower edge of the weir gate and the bottom of the canal section, which seal strip allows curvilinear movement of the weir gate lower edge and prevents flow of water between the lower edge of the weir gate and the bottom of the canal section.
