The present invention flood or less sudden fear of increased loss and displacement by the flow rate at the time of snowfall, increase the affordability of city construction in lightweight structures, aquatic plants and various fish, provide habitat for birds such as the more you can environmentally relates to scour prevention hasangyong blocks that can maintain the ecosystem of the river.
To this end, the through groove is located a flat portion projection body around the through-groove in the block formed, add an open passage to the structure side to the opening hole shape to each other in connection with the through-grooves formed in the body interior of the scour prevention block and the features.
Then, the flat block to prevent scour the body part protruding geometric shape and appearance, protecting a structure from the plane of the load due to the pressure and consequent sediment flow rate of the river.
In addition, through formed in the scour prevention block groove and the opening hole has a structure in which each linked through a passageway inside the structure body, due to the flow rate of iteration and the usual flood when the passage and sediment accumulate around the body of the scour prevention block has been stable in three holes, nine gaphwa phenomenon of bed and received, so because to prevent the loss of its structure in accordance with the sudden ambient change of the protection of such aquatic plants and shellfish samneun a passageway to the livelihood river there is a large effect on the surrounding ecosystem maintained.
