ABSTRACT:
A wall construction block for the construction of earth retaining walls includes a pair of spaced-part transverse pin receiving channels in the end walls of the block and disposed parallel to one another along respective longitudinal axis of the block which are parallel with a front face of the block. The pin receiving channels extend transverse from a top surface to a bottom surface of the block and are of substantially uniform cross-section throughout. Arresting pin elements are received in sliding fit within some of the receiving channels and are retained captive therein. Elongated parallel grooves are provided on a top surface of the block and extend across the end walls and parallel to the front wall. One of the groove is aligned between a first set of the pin receiving channels and the other of the parallel grooves is offset a predetermined distance between the other set of pin receiving channels. When the blocks are disposed in rows one on top of one another, with the top wall of the block facing upwards, the rows of blocks are arrested from transverse shifting by positioning arresting pin elements in selected ones of the sets of transverse pin receiving channels. The pins extend out of the bottom wall of the uppermost block and into a selected one of the pair of grooves in a top surface of the lower block.
