Title:
INTERLOCKED GRIDWORK FOR RETAINING WALLS, AND THE LIKE
Document Type and Number:
WIPO Patent Application WO/1993/011306
Kind Code:
A1
Abstract:
A gridwork or crib structure is formed from reinforced, injection molded plastic or structural foam plastic crossbeams (11), stringers (13), and fascia members (14), by interlocking the members and pinning the stringers together to form a structure which can function as a gravity retaining wall to retain earth, as a structural wall, or as a water wall. The individual crossbeams include elongated slots (20) and holes (17) into which are connected the stringers, which are then locked and pinned together, thereby forming an initial crib or grid layer at ground level. This crib or grid layers can be built up in height and depth to provide an open structure defining securement channels into which earth (38) is filled. It is relatively easy to build the crib or grid layers to follow uneven perimeters. Openings (33) in fascia elements of the crib or grid enables planting of vegetation into the earth fill for soil retention or decoration.
