Abstract
Abstract A cast concrete construction element particularly suitable for use in constructing a retaining wall for a soil mass. The construction element includes a face panel in the form of a rectangular prismatic solid. Extending rearwardly from the face panel is an embedment beam which will extend into and engage firmly with the soil mass. The embedment beam includes a sloping rearward wall to penetrate the soil mass, pan inserts and grooves to increase frictional resistance with the soil mass. The embedment beam also includes notches for interengagement with support beams in the soil mass. The embedment beam may take a variety of configurations which may be used to construct differing retaining wall arrays.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
130 words
A retaining wall construction element for retaining a soil mass comprising: (a) an upstanding face panel, said face panel being a prismatic solid having a forward wall, a rearward wall, side walls, and a top and bottom wall; (b) an embedment beam integrally extending from the rearward wall of said face panel in a generally T shaped arrangement in plan view, said embedment beam being a prismatic solid having an upper wall, a lower wall, side walls, and a sloping rear wall, said embedment beam extending into said soil mass; and (c) said embedment beam having soil mass engagement means disposed on at least one of said side walls and said rear wall, said soil mass engagement means providing a frictional engagement between said embedment beam and said soil mass.
Claim 2
Dependent Claim
130 words
A retaining wall construction element for retaining a soil mass comprising: (a) an upstanding face panel, said face panel being a prismatic solid having a forward wall, a rearward wall, side walls, and a top and bottom wall; (b) an embedment beam integrally extending from the rearward wall of said face panel in a generally T shaped arrangement in plan view, said embedment beam being a prismatic solid having an upper wall, a lower wall, side walls, and a sloping rear wall, said embedment beam extending into said soil mass; and (c) said embedment beam having soil mass engagement means disposed on at least one of said side walls and said rear wall, said soil mass engagement means providing a frictional engagement between said embedment beam and said soil mass.
