Between each pair of wales horizontally supported on sheet-pile walls in facing relationship, struts spaced apart in parallel are provided to form an earth retaining frame. Each strut comprises a plurality of standard strut elements connected together, a junction of which is forced apart by a hydraulic jack which is interposed between the strut elements eccentrically of the axis of the strut. In the space thus expanded between the strut elements, an auxiliary strut element and a screw jack are provided. The strut is formed of the standard elements, auxiliary element and screw jack arranged in combination in pressing contact with the wales against the earth pressure.
