The present invention relates to a retaining wall block, a retaining wall block assembly, and a construction method thereof. The retaining wall block having a decorative board (S) mounted on the front surface comprises: a first coupling groove (110) laterally formed on the top to arrange a tensile bar; third coupling grooves (130) vertically cut in the upper part of the front surface at a predetermined depth and communicated with the first coupling groove; and fixing devices (50) having a front end (51) arranged in the third coupling groove and a rear end (55) arranged in the first coupling groove and in which fixing pins penetrating the decorative board are inserted. A mounting groove on which the rear end of the fixing device is mounted is additionally formed on the first coupling groove. The present invention can conveniently and safely mount the decorative board on the front surface of retaining wall blocks while making the appearance of the decorative board beautiful. The retaining wall block assembly formed by laterally connecting the retaining wall blocks on which the decorative board is conveniently mounted by the fixing device and the construction method thereof can improve the erection force, durability, and safety of the retaining wall assembly and retaining walls by obtaining a tensile force using the tensile bar and a coupling force between the retaining wall blocks using a coupling reinforcing bar. |
