Self Closing Flood Barrier (Scfb)

When in non-flood condition, all operational parts are invisibly concealed in the ground inside the basin. When the flood water enters the basin, the floating wall barrier will be started to float up. When the floating wall rises via the guide rail or slot in the highest position, the angle support block will lock the wall in position in few minutes. When the water level subsides, it will back to the normal position, the flood barrier wall will be concealed in the ground. The barrier is not power driven, over 30 years life span. 
The barrier height can be 500mm - 2500mm.
