Abstract:
A retaining-wall system comprising:a pair of substantially identical walls having longitudinally extending and upwardly directed top wall surfaces and longitudinally juxtaposed and stepped longitudinal ends each unitarily formed with a longitudinally protruding lower end-portion having an upwardly directed top end-portion surface spaced substantially below the top wall surface and a horizontally directed lower end surface below the top end-portion surface, the lower end portions abutting one another, an upwardly directed lower connection formation at the top end-portion surface, and a horizontally directed upper end surface extending between the respective top end-portion surface and the respective top wall surface and set longitudinally back from the respective lower end surface, whereby confronting upper end surfaces and the adjacent end-portion top surfaces form an upwardly open recess; and a splice body overlying the abutting lower end portions, substantially filling the recess, having a body top surface horizontally level with the top wall surfaces, and formed with upper downwardly directed upper connection formations fitting with and complementary to the respective upwardly directed lower connection formations, whereby the splice body joins the walls.
