Filling the NoFloods Flood Barrier is a multi-step process that involves both air and water. Here’s a detailed explanation of the filling procedure:
Air Filling:
- To initiate the filling process, air is introduced into the tubes of the Flood Barrier. This is typically achieved using an air blower, that is connected to the Terminal or Junction of the barrier.
- The introduction of air serves to align the inner liner with the outer liner in each tube of the barrier. This alignment is important for optimal performance.
- Air filling also allows for the final positioning of the barrier, ensuring that it is correctly set up before water filling.
Water Filling:
- After the initial air filling, the Flood Barrier is ready for water filling. Water is sourced from the sea, river, stream, or another suitable water source.
- Water pumps are used to transfer water from the source to the Flood Barrier. These pumps are connected to the Terminal or Junction of the barrier
- The filling process begins from the upstream end of the barrier, which is the side facing the expected direction of floodwater.
The filling process is gradual, allowing the air to be pushed out and relieved by the advancing water towards the upstream end of the barrier. The air must be released gradually in a process that requires monitoring.
In summary, the NoFloods Flood Barrier is filled in two main steps: first with air to align the inner and outer liners for setting up the barrier, and then with water to provide the stability and ground adhesion that ultimately ensures that the barrier is properly installed and prepared to withstand flooding.
