First pile for construction of Dubbele Dijk tidal culvert in the ground
With a resounding blow, Delta Program Commissioner Peter Glas, Annette van Velde of Noorderzijlvest Water Authority, Johan Koopmans of the Province of Groningen, and representatives of the Flood Protection Programme, the Wadden Fund, and Friso Bouwgroep drove the symbolic first pile for the construction of the Dubbele Dyke tidal culvert in Bierum today. The festive kickoff took place in the presence of participants on an excursion to the Dubbele Dyke, as part of the National Delta Congress in Groningen.
A 92 metre pipe
Since August, intensive work has been underway to construct the construction pit. This watertight steel structure protects the land from flooding and allows for safe construction of the dyke passage during storm season. Now that the construction pit is complete, the piles for the foundation can be driven into the ground. The tidal culvert a concrete tube nearly 92 metre , with a diameter of 2 metre and 3.5 metre . Saltwater will flow in and out of the area through this tube. The work is being carried out by a joint venture between Friso Civiel and Heuvelman Ibis.
Tidal culvert
The tidal culvert the Eems River connexion the area behind the sea dyke. A pipe dyke installed in the dyke through which saltwater flows into and out of the area twice a day. As a result, the area between the two dykes is dykes influence of the tides (ebb and flow). Due to tidal action, silt from the Eems can settle here, creating a brackish water ecosystem. The brackish water also makes saline agriculture and aquaculture possible.
Double Dyke Trial
The Double Dyke Bierum is a pilot project by Noorderzijlvest Water Authority, the province of Groningen, and the national Flood Protection Programme HWBP). The project is investigating whether the Double Dyke is Dyke alternative to raising and widening dykes. What makes this innovative dyke unique dyke its combination of flood protection, nature, agriculture, and recreation. The pilot is also part of the multi-year programme 2050 programme .
