An installation structure of an eco-friendly vegetation block for a river slope is provided to prevent river erosion, to improve the water quality and to form ecological environment of underwater creatures using a vegetation block with aquatic plants, a circular gabion and a circular frame made of waste tire. An installation structure of an eco-friendly vegetation block for a river slope comprises: a shear reinforcement plate(10) fixed to the inside of a river slope and provided with many hanging projections and a coupling projection having many coupling holes; a lower foundation plate(20) fixed to the riverbed and provided with an insertion part formed on the right to insert the coupling projection of the shear reinforcement plate using a coupling bolt and a nut, installation holes formed on the center, anchor bolts fixed to both sides of the installation hole, and many fixing holes formed on the left; slope protection blocks(30) arranged tightly to protect a river slope and provided with a lower foundation anchor fixed to the installation hole of the lower foundation plate, a fixing disk having anchor holes, a vertical coupler having an anchor bolt projected vertically and coupled with an upper coupling plate by a nut, a circular frame made of recycled waste tire and inserted between the fixing disk and the upper coupling plate; a vegetation block(40) provided with a lower foundation anchor inserted to an installation hole of another lower foundation plate adjacent to the lower foundation plate fixed with the slope protection block, a fixing disk having anchor holes, a vertical coupling bar having an anchor bolt projected vertically and coupled with an upper coupling plate by a nut, and a circular vegetation block with many aquatic plants and a circular gabion inserted to the fixing disk in order; and a riprap filling frame(50), a U-shaped board fixed to the riverbed, provided with a coupling groove to insert the left end of the outermost lower foundation plate and to fix with coupling bolts and nuts, a riprap filling groove filled with riprap(52), and a semicircular upper cover frame(54) having underwater ecological moving holes(55) to supply the habitat and spawning place for underwater creatures. |
