ABSTRACT:
An earth-retaining module for use in an interlocked, earth-retaining wall system, and to a method of preparing an earth-retaining wall system, wherein the module comprises a front wall and side walls, to form a structure to receive earth or sand therein, the side walls having a rear, straight, sloped, side section extending from the top of the side walls to a defined height of the rear of the side walls. The side walls have open notches in the top sections therein and longitudinally aligned, to permit the insertion of the front-wall section of another module in a higher row within the open notches. The side walls have inward, rear projections, to retain a dead-man slab element, with the removable dead-man slab element placed on the rear-mounting side walls. The module includes a plurality of holes in the side walls, to permit the side walls of adjoining modules to be secured together by pins or bolts. The system comprises arranging the secured, side-by-side modules in rows and stepped back from the first row in an interlocked manner, by insertion of the front row of the module in the open notches of the lower modules, and filling the secured, interlocked modules with earth or sand.
