Weir Crib Groyne for Bed Scour Protection at the Downstream of Weir

摘要

The present invention is flooded by heavy rains due to weir facilities installed across the rivers to collect water from the rivers, and the downstream facilities are spreading year by year due to natural disasters. The present invention relates to a river bed protection frame structure that can be protected.;This design is based on the flow of water flowing over the beam 10 during flooding. The protection frame structure is provided, and the frame structure is made of raw logs, and the horizontal and vertical (2) connections are fixed with anchor bolts (8) to prevent flow, and the space between the frames is filled with amber and crushed rubble (4) to flow any heavy rain by own weight. It can cope with resistance, protects property from natural disasters, secures a safe working space for fish and habitats for fish, so it is stable considering the natural environment of the river ecosystem, and maintenance costs are reduced, and economical riverbed protection frame structure is provided. do.
