BLOCK FOR THE CONSTRUCTION OF RETAINING WALLS

摘要

A block for the construction of a retaining wall comprises a body of concrete material having upper and lower faces of like contour, each face being formed with a pair of dihedral protrusions and a pair of dihedral recesses, the protrusions and recesses alternating with each other and extending in parallel relationship. The protrusions and recesses of the upper face are complementary to the recesses and protrusions respectively of the lower face to define upper and lower bearing surfaces. A retaining wall may be formed by arranging a plurality of such blocks in courses one above the other with the protrusions and recesses defining the lower bearing surface of a block interfitting respectively with the recesses and protrusions defining the upper bearing surface of an underlying block, the protrusions and recesses permitting self-alignment of the blocks while preventing displacement thereof in a direction normal to the courses.
