The present invention relates to a grating used to prevent a wild animal invasion; and to a roadkill-preventive road gate using the same. The grating used to prevent a wild animal invasion comprises: a zig-zag bent member which is bent in zig-zags so a longitudinal part and a horizontal part bent diagonally widthwise are sequentially repeated to repeatedly form an isosceles trapezoid, and has a joint hole formed on the flank of the longitudinal part; a flank support member with a joint hole corresponding to the joint hole of the longitudinal part; and a joint device penetrating the joint holes to fasten the zig-zag bent member and the flank support member. The zig-zag bent member and the flank support member are repeatedly arranged and fastened by the joint device so the grating is easily fastened. A maximum tangent circle touching an isosceles trapezoidal gap is larger than a maximum tangent circle touching a rectangular gap, thereby increasing a probability that the foot of a wild animal will be stuck into the isosceles trapezoidal gap. Accordingly, the wild animal can hardly pass the grating. The road gate embedding the grating therein is installed by cutting a road between a main road equipped with a fence and an auxiliary road and embedding the grating. Accordingly, a wild animal is prevented from approaching the main road. Furthermore, an open passage is formed widthwise during an embedding process of the grating, thereby forming an escape route and a passage for a small organism stuck into the isosceles trapezoidal gap. In addition, the grating is mounted on a road without a road cutting process, and an inclined part is formed on both longitudinal ends of the grating so the grating is easily mounted and also functions as a speed hump. |
