PURPOSE:To quickly and safely construct a retaining wall for sheathing by a method in which secondary concrete products of an almost trapezoidal form, having a pair of hanging inversional holes in the outer surface of the surface and back walls of its longitudinal central partition wall, are fed and set on a construction site. CONSTITUTION:Secondary concrete products A of an almost trapezoidal form for retaining wall, having an opening 1 passing through its upper and lower faces and a cavity 2 leading to its inside and the opening 1, are produced in a factory. For the product A, the cavity 2 is partitioned in the longitudinal central position and the surface and back walls 3 and 4 are led to each other by a partition wall 5, and a pair of hanging inversional holes 10 are formed in the outer surface of the walls 3 and 4. In constructing a retaining wall, the bars of hanging inversional jigs are inserted into the holes 10 to lift up the products A. The secondary concrete products A can thus be easily transported and positioned.
