The Challenge
This structure serves for the regulation of water on the Weser Island. The combination of corrugated, curved and corrosion-protected steel parts with components made of HDPE enables operations like this. The inlet and outlet of the corrugated steel pipe are provided with factory-welded, reinforced and also corrosion-protected steel aprons, to which a back-flow gate and a double overflow valve are welded.The double overflow valve provided with four non-rising stainless steel spindles serves for the regulation of the water level with ebb tide.
