Abstract
Abstract A foundation for a retaining wall-type of structure acted upon by a principal force tending to slide same in a predetermined direction is anchored by a plurality of slide resisting walls. The slide resisting walls extend parallel to the predetermined direction in which the foundation tends to slide. The upper portions of the slide resisting walls are embedded in a concrete mass. The lower portions of the slide resisting walls project downwardly from the concrete mass into the earth, and are solely in engagement with the earth and not with concrete.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
212 words
A foundation for a retaining wall-type of structure for holding back a mass which acts on the structure with a principal horizontal force tending to cause said foundation to slide relative to the earth in a predetermined direction, said foundation comprising: a plurality of slide resisting walls extending generally parallel to said predetermined direction, said slide resisting walls being spaced-apart transversely of said predetermined direction, said slide resisting walls having lower portions embedded in the earth and upper portions extending upwardly out of the earth, and a concrete mass covering said upper portions of said slide resisting walls and occupying the spaces therebetween to form a foundation, said lower portions of said slide resisting walls projecting downwardly from said concrete mass into the earth and being solely in engagement with the earth and not with concrete, whereby sliding movement of said foundation in said predetermined direction is resisted by the interlocking relationship between said concrete mass and said upper portions of said slide resisting walls and by the resistance to sliding of said lower portions of said slide resisting walls relative to the earth in a direction parallel to the length of said slide resisting walls by virtue of said lower portions of said slide resisting walls being embedded in the earth.
Claim 2
Dependent Claim
212 words
A foundation for a retaining wall-type of structure for holding back a mass which acts on the structure with a principal horizontal force tending to cause said foundation to slide relative to the earth in a predetermined direction, said foundation comprising: a plurality of slide resisting walls extending generally parallel to said predetermined direction, said slide resisting walls being spaced-apart transversely of said predetermined direction, said slide resisting walls having lower portions embedded in the earth and upper portions extending upwardly out of the earth, and a concrete mass covering said upper portions of said slide resisting walls and occupying the spaces therebetween to form a foundation, said lower portions of said slide resisting walls projecting downwardly from said concrete mass into the earth and being solely in engagement with the earth and not with concrete, whereby sliding movement of said foundation in said predetermined direction is resisted by the interlocking relationship between said concrete mass and said upper portions of said slide resisting walls and by the resistance to sliding of said lower portions of said slide resisting walls relative to the earth in a direction parallel to the length of said slide resisting walls by virtue of said lower portions of said slide resisting walls being embedded in the earth.
Claim 3
Dependent Claim
20 words
The foundation of claim 1 wherein each said slide resisting wall is defined by a plurality of interlocking metallic sheet-piles.
Claim 4
Dependent Claim
55 words
The foundation of claim 1 including a pair of support walls extending generally perpendicular to said slide resisting walls and located such that said slide resisting walls extend therebetween, all of said walls having upper ends, and said upper ends of said support walls being located above said upper ends of said slide resisting walls.
Claim 5
Dependent Claim
28 words
The foundation of claim 3 including a platform supported on said upper ends of said support walls, said concrete mass occupying substantially the entire space beneath said platform.
Claim 6
Dependent Claim
34 words
The foundation of claim 4 wherein said platform includes a plurality of spaced-apart girders extending substantially perpendicular to said slide resisting walls and spaced above same, said girders being embedded in said concrete mass.
Claim 7
Dependent Claim
24 words
The foundation of claim 3 wherein said slide resisting walls are spaced-apart from one another about 5-10 times the distance between said support walls.
Claim 8
Dependent Claim
25 words
The foundation of claim 1 wherein said upper portions of said slide resisting walls project upwardly out of the earth about 0.30 to 1 meters.
Claim 9
Independent Claim
166 words
A method of constructing a foundation for a retaining wall-type of structure which holds back a mass exerting a principal horizontal force on such structure tending to cause said foundation to slide relative to the earth in a predetermined direction, comprising the steps of: forming a plurality of spaced-apart slide resisting walls extending generally parallel to said predetermined direction by embedding lower portions of such walls in the earth while leaving upper portions thereof projecting upwardly out of the earth, covering said upper portions of said slide resisting walls and filling the spaces therebetween with a concrete mass to form a foundation while leaving said lower portions of said slide resisting walls projecting downwardly from said concrete mass into the earth and being solely in engagement with the earth and not with concrete, and allowing said concrete mass to harden for interlocking same with said upper portions of said slide resisting walls and thereby providing resistance to sliding movement of said foundation in said predetermined direction.
Claim 10
Independent Claim
166 words
A method of constructing a foundation for a retaining wall-type of structure which holds back a mass exerting a principal horizontal force on such structure tending to cause said foundation to slide relative to the earth in a predetermined direction, comprising the steps of: forming a plurality of spaced-apart slide resisting walls extending generally parallel to said predetermined direction by embedding lower portions of such walls in the earth while leaving upper portions thereof projecting upwardly out of the earth, covering said upper portions of said slide resisting walls and filling the spaces therebetween with a concrete mass to form a foundation while leaving said lower portions of said slide resisting walls projecting downwardly from said concrete mass into the earth and being solely in engagement with the earth and not with concrete, and allowing said concrete mass to harden for interlocking same with said upper portions of said slide resisting walls and thereby providing resistance to sliding movement of said foundation in said predetermined direction.
Claim 11
Dependent Claim
63 words
The method of claim 8 including the step of forming a pair of spaced-apart support walls extending substantially perpendicular to said predetermined direction by embedding lower portions of such walls in the earth while leaving upper portions thereof projecting upwardly out of the earth, and said step of forming such slide resisting walls being carried out by forming same between said support walls.
Claim 12
Dependent Claim
46 words
The method of claim 9 wherein said support walls and slide resisting walls have upper ends and said steps of forming said walls are carried out such that said upper ends of said support walls are spaced above said upper ends of said slide resisting walls.
Claim 13
Dependent Claim
36 words
The method of claim 10 including the step of supporting a platform on said upper ends of said support walls prior to said step of covering said upper portions of said slide resisting walls with concrete.
Claim 14
Dependent Claim
63 words
The method of claim 11 wherein said step of supporting a platform on said upper ends of said support walls is carried out by providing a platform having girders spaced above said upper ends of said slide resisting walls, and said step of covering said upper portions of said slide resisting walls being carried out by also embedding said girders in such concrete.
Claim 15
Dependent Claim
41 words
The method of claim 8 including the step of supporting a platform independently of and spaced above said upper ends of said slide resisting walls prior to said step of covering said upper portions of said slide resisting walls with concrete.
