    • PROBLEM TO BE SOLVED: To provide an earth retaining wall construction method by which natural ground can be protected and the earth retaining wall can be inexpensively constructed in a high efficiency without necessity of construction of a scaffold and blocks appropriate for the same. SOLUTION: A part of lower natural ground between upper stage block groups connected in the lateral direction of the upper part of the slope face is excavated to form an excavated slope face and an unexcavated natural ground. A part of the lower stage block groups and the upper stage block groups is vertically integrated. Next, an unexcavated natural ground left in the lateral direction of the lower stage block groups and in the lower aside of the upper stage block groups is excavated and formed. While a series of processes where other lower stage block groups are arranged and vertically and laterally integrated, is repeated in several times in the vertical and horizontal directions, the retaining wall is constructed downwards from above in the retaining wall construction method. A gap 11 for placing concrete having a concrete-placing opening 5 is formed above by the retaining wall construction method and a stay slab 8 obliquely formed in the front face via a beam 12, and a filling part 10 is formed at the back of the stay slab, in the retaining wall block.
