Another steel soil retaining plate is coupled onto the prefabricated steel soil retaining plate 1 by connecting the two steel soil retaining plates 1 to the angle bar 3 by the coupling bolt 42.

[42] Since the prefabricated steel soil retaining plate 1 is coupled to the fixing jig 4 by the coupling bolt 42, it can be easily dissembled by merely unscrewing the coupling bolt 42.

[43] As described above, the prefabricated steel soil retaining plate of the present embodiment that makes it possible to prevent falling rocks or soil from reaching the roadside forms an integrally firm soil retaining plate, increases general working efficiency by fabricating and fixing a steel soil retaining plate, resulting in a reduction of a construction period.

[44] The steel soil retaining plate is conveniently dissembled and collected, resulting in its recycling and a reduction in its costs.

[45] A prefabricated steel soil retaining plate according to another embodiment of the present invention comprises an engagement unit that is bent in the shape of '-| ' so that both ends of a steel plate are inserted between flanges of H shaped steel, a predetermined engagement hole that is formed in the engagement unit and is engaged with a bolt, and a steel soil retaining plate to which a reinforcing L shaped angle bar is connected on the upper and lower parts of the steel plate, in which one or more ho- rixmtal long hole is formed in the angle bar that is installed in the lower portion of the steel soil retaining plate, a protrusion piece is formed in the angle bar that is installed in the upper portion of the steel soil retaining plate and is disposed to correspond to the horixmtal long hole.

[51] The diameter of the horixmtal long hole 31 formed in the lower angle bar 3 may be slightly greater than that of the protrusion piece 32 formed in the upper angle bar 3 so that the horixmtal long hole 31 can be easily inserted into and released from the protrusion piece 32.

[52] A triangular protrusion unit 13 is formed in the center of the prefabricated steel soil retaining plate to distribute soil pressure. Therefore, a strong pressure of soil is applied to the prefabricated steel soil retaining plate 1 and is distributed from the center of the protrusion unit 13 to both sides thereof, thereby minimizing damage or modification of the prefabricated steel soil retaining plate 1.

[53] Meanwhile, one or more engagement holes 121 may be formed in the engagement unit 12 of the prefabricated steel soil retaining plate 1.
