PURPOSE:To raise the efficiency of construction work for retaining walls by a method in which wall pieces are set by contacting their both end portions with the coupling faces of unit shape steels erected by turning their longitudinal directions upwards, having couplers to be connected with tension cables on the back, for constructing strong retaining wall. CONSTITUTION:H-shape steels 4 are erectly set by turning their longitudinal directions upwards at given intervals. One end sides 6a and the other end sides 6b of the blocks 6 are mutually contacted and set on the first coupling faces 4a of the H-shape steels 4 and the coupling faces 4b of the other side of the H-shape steels 4. Tension cables 22 are attached through couplers 24 to the backs of the H-shape steels 4 positioned on the backs of the retaining wall 2. The coupler 24 consists of a fixer 26 and an attachment 28. The wall pieces can thus be strongly supported and the retaining wall having high strengths can be constructed with simplified assembling operations. |
