Construction Materials
The SCFB consists of a prefab steel or concrete basin and a polyester floating wall. The wall itself is prefabricated polyester made to a thickness of 120 – 200 mms. It is laminated in a climate controlled environment with permanent humidity and temperature control to guarantee a consistent lamination process. In order to minimize the impact of flotsam, the exposed area of the floating wall is protected by Kevlar; synthetic material developed by Dupont. Its high 'strength to weight' ratio makes it 5 times stronger than steel on an equal weight basis. The wall is reinforced by laminated steel strips. The wall is filled up with a PUR-foam core in a very strong sandwich constructionand hence does not absorb water, while retaining its buoyancy. The walls are coupled in lengths of 990 mms by means of a rubber bib. Two rubber elements at the wall side close off the chaser in that the system operates waterproof. The strength of the wall is calculated in terms of a minimum of 10 times the sideways water pressure.
By coupling 2 side plates together, it is feasible to cover any angle and corner with this system.
The stainless steel lid closes off the entrenchment area to prevent any inflow of waste or debris. Under normal conditions when the SCFB is not in operation, the entrenched ‘wall’ is not visible and hence cannot cause any obstruction to any kind of traffic.
