Abstract
Abstract A retaining wall for earth and similar material has its front face formed by a series of prefabricated reinforced-concrete panels. In use, the prefabricated panels are arranged vertically in side-by-side relation and rest on a concrete footing cast in situ. The prefabricated panels are rigidly connected to a concrete anchor bed cast during the course of construction and which extends away from the prefabricated panels towards the earth to be retained. The said concrete anchoring bed is disposed at a level higher than the base of said panels and is spaced from the latter by a distance of between 1/5 and 1/2 of the total height of the said panels.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A retaining wall for earth and similar material, said wall comprising a concrete footing girder, a series of prefabricated reinforced concrete panels arranged substantially vertically in side-by-side relation on said concrete footing girder for pivotal movement relative to said girder, and a concrete anchoring bed cast in situ and extending horizontally towards the earth to be supported, said anchoring bed being rigidly connected to said panels; wherein said concrete anchoring bed is situated at a level which is at a distance above the bottom of said panels of between 1/5 and 1/2 of the total height of said panels.
Claim 2
Dependent Claim
99 words
A retaining wall for earth and similar material, said wall comprising a concrete footing girder, a series of prefabricated reinforced concrete panels arranged substantially vertically in side-by-side relation on said concrete footing girder for pivotal movement relative to said girder, and a concrete anchoring bed cast in situ and extending horizontally towards the earth to be supported, said anchoring bed being rigidly connected to said panels; wherein said concrete anchoring bed is situated at a level which is at a distance above the bottom of said panels of between 1/5 and 1/2 of the total height of said panels.
Claim 3
Dependent Claim

A wall according to claim 1, wherein, in use, the said prefabricated panels are inclined with respect to the vertical towards the earth to be retained, at an angle of between 5 and 20 degrees.
Claim 4
Dependent Claim
47 words
A wall according to claim 1 wherein each of said panels is provided with metal reinforcement rods which protrude from a part of each panel to which said concrete anchoring bed is connected, said reinforcement rods being incorporated within said concrete bed when said bed is cast.
Claim 5
Dependent Claim
61 words
A wall according to claim 1 wherein each of said panels is provided on its side facing towards the earth to be retained with at least one longitudinal rib extending from top to bottom of each panel, said rib being provided with reinforcement rods which protrude from said rib for incorporation within the said concrete bed when said bed is cast.
Claim 6
Dependent Claim
41 words
A wall according to claim 4 wherein in each panel the part of said longitudinal rib lying between the section that is to be connected to said concrete anchoring bed and the bottom of said panel has a T-shaped transverse section.
