Abstract
A retaining wall structure built of wall-building units such as sand/soil bags or hardenable building units such as clay bricks has interconnecting members placed between adjacent courses of units to attach the adjacent courses to one another. The interconnecting members have projections on both sides which protrude into the wall-building units of the adjacent courses. Sheets of geogrid preferably extend from between some of the courses of wall-building units into the fill retained by the wall-building units. Projections on the interconnecting members protrude through holes in the geogrid sheet, anchoring the wall face to the reinforced soil structure.
Claims13
A retaining wall structure comprising a first plurality of hardenable building units positioned adjacent to one another forming a first horizontally-extending course, a second plurality of hardenable building units positioned adjacent to one another above said first course forming a second horizontally-extending course, and interconnecting members between said first course and said second course, said interconnecting members comprising a body having an upper side and a lower side, each said side having a plurality of projections thereon, said projections being capable of protruding into said hardenable building units in said first course and said second course, said body extending across at least part of two horizontally-adjacent hardenable building units in said first course or said second course, with said projections on said upper side or said lower side positioned to protrude into said two horizontally-adjacent hardenable building units, said projections on said lower side comprising at least three projections positioned on said lower side to support said body in a generally horizontal position on said first course when said interconnecting member is placed on said first course.
A retaining wall structure comprising a first plurality of hardenable building units positioned adjacent to one another forming a first horizontally-extending course, a second plurality of hardenable building units positioned adjacent to one another above said first course forming a second horizontally-extending course, and interconnecting members between said first course and said second course, said interconnecting members comprising a body with projections capable of protruding into said hardenable building units in said first course and in said second course, characterized in that said body has an upper side and a lower side, each said side having a plurality of projections thereon, said body extending across at least part of two horizontally-adjacent hardenable building units in said first course or said second course, with said projections on said upper side or said lower side positioned to protrude into said two horizontally-adjacent hardenable building units, wherein said interconnecting member further comprises a set of geogrid-holding members on the upper side of said body shaped and adapted to protrude through holes in a sheet of geogrid, and wherein said retaining wall structure further comprises a sheet of geogrid extending from between said first and second courses into fill behind said retaining wall structure, said geogrid sheet having a plurality of holes therein and said geogrid sheet being so positioned that said geogrid-holding members protrude through said holes of said geogrid sheet.
A retaining wall structure comprising a first plurality of hardenable building units positioned adjacent to one another forming a first horizontally-extending course, a second plurality of hardenable building units positioned adjacent to one another above said first course forming a second horizontally-extending course, and interconnecting members between said first course and said second course, said interconnecting members comprising a body with projections capable of protruding into said hardenable building units in said first course and in said second course, characterized in that said body has an upper side and a lower side, each said side having a plurality of projections thereon, said body extending across at least part of two horizontally-adjacent hardenable building units in said first course or said second course, with said projections on said upper side or said lower side positioned to protrude into said two horizontally-adjacent hardenable building units, wherein said body of said interconnecting member has one or more water drainage holes.
A retaining wall structure comprising a first plurality of wall-building units positioned adjacent to one another forming a first horizontally-extending course, a second plurality of wall-building units positioned adjacent to one another above said first course forming a second-horizontally-extending course, and interconnecting members between said first course and said second course, said interconnecting members comprising a body with projections capable of protruding into said wall-building units in said first course and in said second course, said body having an upper side and a lower side, each said side having a plurality of projections thereon, said body extending across at least part of two horizontally-adjacent wall-building units in said first course or said second course, with said projections on said upper side or said lower side positioned to protrude into said two horizontally-adjacent wall-building units, said projections on said lower side comprising at least three projections positioned on said lower side to support said body in a generally horizontal position on said first course when said interconnecting member is placed on said first course.
A method of constructing a retaining wall structure having a plurality of courses of hardenable building units, comprising the steps of placing a first plurality of hardenable building units adjacent to one another to form a first horizontally-extending course, placing interconnecting members on said first course, said interconnecting members comprising a body with projections capable of protruding into said hardenable building units in vertically adjacent courses, placing a second plurality of hardenable building units adjacent to one another to form a second horizontally-extending course above said first course such that said projections protrude into said hardenable building units of said second course, said body having an upper side and a lower side, each said side having a plurality of projections thereon, said body extending across at least part of two horizontally-adjacent hardenable building units in said first course or in said second course, with said projections on said upper side or said lower side protruding into said two horizontally-adjacent hardenable building units, said projections on said lower side comprising at least three projections positioned on said lower side to support said body in a generally horizontal position on said first course when said interconnecting member is placed on said first course, and allowing or causing said hardenable building units to harden.
