Abstract
An improved method and apparatus for constructing a soil reinforced earthen retaining wall wherein successive soil reinforcing mats embedded within an earthen formation have bent-up face elements which are slidably engaged to enable the earthen formation to settle without bulging the face elements. Backing mats are disposed behind the face elements for movement relative thereto in generally vertical planes. The backing mats serve to support the successive soil reinforcing mats and permit the mats to more toward one another to accommodate settling of the formation without bulging of the face elements.
Claims21
A soil reinforced retaining wall for an earthen formation, comprising:
- a) a plurality of welded wire soil reinforcing mats successively embedded in the formation one above the other in generally horizontal spaced relationship, each mat having a generally horizontal floor comprised of a gridwork of wires and a face comprised of generally vertically extending wires wherein the wires of the face of each mat are held against horizontal displacement by the reinforcing mat thereabove and are free to move vertically relative thereto;
- and,
- b) a welded wire backing mat disposed behind the vertically extending wires of the face of each reinforcing mat for movement relative thereto in a generally vertical plane, each backing mat having an element for supporting engagement with the next successive reinforcing mat thereabove and being spaced from the floor of the reinforcing mat therefor to permit the next successive reinforcing mat to settle to accommodate settling of the earthen formation.
A method of constructing a soil reinforced retaining wall for an earthen formation, comprising:
- a) embedding a plurality of welded wire soil reinforcing mats in the formation in generally horizontal spaced relationship to one another so that each mat has a generally horizontal floor comprised of a gridwork of wires and a face comprised of generally vertically extending wires wherein the wires of the face of each reinforcing mat are held against horizontal displacement by the mat thereabove and are free to move vertically relative thereto;
- and,
- b) positioning a welded wire backing mat behind the vertically extending wires of the face of each reinforcing mat for movement relative thereto in a generally vertical plane, each backing mat being disposed for supporting engagement with the next successive reinforcing mat thereabove and being spaced from the floor of the reinforcing mat therefor to permit the next successive reinforcing mat to settle to accommodate settling of the earthen formation.
A soil reinforced retaining wall for an earthen formation, comprising:
- a) first and second welded wire soil reinforcing mats embedded in the formation in generally horizontally horizontal spaced relationship with the second mat being disposed above the first mat and the first mat having a face extending upwardly from one end thereof toward the second mat;
- and,
- b) support means carried by the face of the first mat and disposed for supporting engagement with the second mat, said means being movable relative to the face to permit the second mat to move vertically relative to the first mat to accommodate settling of the earthen formation without bulging of the face.
A soil reinforced retaining wall for an earthen formation comprising:
- a) first and second welded wire soil reinforcing mats embedded in the formation in generally horizontal spaced relationship, with the second mat being disposed above the first mat;
- b) a face secured to and extending upwardly from one end of the first mat and toward the second mat;
- and,
- c) support means carried by the face and disposed for supporting engagement with the second mat, said means being movable relative to the face to permit the second mat to move vertically relative to the first mat to accommodate settling of the earthen formation without bulging of the face.
