An upper panel of a retaining wall system is provided to increase the height of the existing panel if the existing panel is lower than the newly excavated wall when using the previously used panel for a newly excavated wall. An upper panel of a retaining wall system comprises an upper plate(110) formed in the same width and thickness as a panel of the retaining wall system installed at an excavated wall to be built on the upper part of the panel, C-shaped fixing bars(120) provided with many holes(121) at two sides and formed in the smaller width than the bracket of the panel to make the bottom inserted to the bracket of the panel and projected to be lower than the bottom of the upper plate so that the bracket of the panel and the fixing bar of the upper plate are coupled with bolts and nuts, a hanger(130) formed on the upper front of the fixing bar to suspend a hook of a crane, and a stiffening piece(140) formed on the lower front of the fixing bar to prevent the deformation. |
