The wall (10) for steep slopes consists of troughed components (12), the side walls (22.1, 22.2) of which have vertical engagement grooves (30.1, 30.2) into which the engagement pins (33) of separately manufactured surrounding beams (14) are introduced. Around the beams (14) are wrapped mineral fabric webs (15) pulled out fairly horizontally at the rear into the earth. Other troughed components (12.2) are placed on the side walls (22.1, 22.2) of troughed components (12.1) arranged in the space between intermediate regions (24). Ground beams (16) may be inserted beneath them at the rear. Upper closing beams (17) may be fitted with earth support flanges (69).
