A scour prevention system for the bottom of a small river is provided to keep plural scour prevention blocks installed on the bottom of a river not to be separated by rapid water velocity by heightening the binding strength of the scour prevention blocks and to restore environment of a riverbed quickly by fixing an aquatic plant vegetation sack to a scour prevention block strongly and rooting aquatic plants on a riverbed quickly. A scour prevention system for the bottom of a small river comprises plural rectangular scour prevention blocks placed on the bottom of a river in a lattice type, anchor hooks(20) installed on the front and the right of the scour prevention block, fitting hooks(30) installed on the rear and the left of the scour prevention block and overlapped to the anchor hooks of the adjacent scour prevention block, and a fastener(40) placed between the anchor hook and the fitting hook to keep the anchor hook and the fitting hook overlapped with each other, wherein the scour prevention block is provided with a rectangular hollow hole at the center to insert an aquatic plant vegetation sack to vegetate aquatic plants, thereby to restore environment of a riverbed quickly and to prevent the outflow of river soils, and a cross-shaped fixing band is installed on the upper part of the scour prevention block to prevent the separation of the aquatic plant vegetation sack from the scour prevention block against flowing water. |
