A block for use in constructing a retaining wall system has a front wall and a partition wall formed backwards projecting from the front wall; wherein the partition wall is provided with a communicating hole extending vertically over the entire length thereof through and in which a reinforcing iron rod is disposed or inserted; the partition wall is provided on an upper surface with an upper depression such that the upper depression is enclosed with an upwardly raised peripheral edge portion having a top flat surface and an inner wall surface of the peripheral raised edge portion is gradually widened downwardly from the top surface edge toward the inside of the upper depression; the partition is further provided on a bottom surface with a lower depression such that the lower depression is enclosed with a downwardly reduced peripheral edge portion and an inner wall surface of the peripheral reduced edge portion is gradually narrowed downwardly from the bottom surface of the lower depression toward the bottom edge thereof; the upper depression communicates with the lower depression via the communicating hole; each of the upper and lower depressions is wider in lengthwise diameter than the communicating hole; the upper depression of the retaining wall block laid in a lower row is aligned upwardly with the lower depression of the adjacent retaining wall block laid in the adjacent upper row so as to form a node-shaped cavity; the communicating hole forms a column-shaped body of a filling and setting material filled through and in the communicating hole; and the node-shaped cavity forms a node-shaped body of the filling and setting material filled therein through the communicating hole.The retaining wall block can withstand external forces and prevent the resulting retaining wall from falling down forwards and backwards. Further, the retaining wall constructed with the retaining wall blocks can withstand external forces acting vertically. |
