Abstract
A modular block wall includes dry cast, unreinforced modular wall blocks with anchor type, or frictional type or composite type soil stabilizing elements recessed therein and attached thereto by vertical rods which also connect the blocks together. The soil stabilizing elements are positioned in counterbores or slots in the blocks and project into the compacted soil behind the courses of modular wall blocks. Alternative stabilizing element designs may be used with the modular wall blocks and other types of facing elements in a mechanically stabilized earth structure.
Claims7
An earthen work structure comprising, in combination:
- a plurality of equally sized, facing blocks, each having a rectangular front wall, a back wall, opposite side walls, a top, a bottom and a bore at least partially through the block between the top and bottom;
- selected facing blocks having a planar back wall;
- a second block with a planar wall fitted against the back wall of a facing block, said second block including a top and bottom with a bore at least partially through the block between the top and bottom and also including a pattern of slots in the top or bottom;
- a connector for holding the facing block and second block together, said connector extending into the respective bores of said facing block and second block;
- a stabilizing tensile member including at least two spaced, longitudinal tensile rods and at least one cross rod connecting the tensile rods, at least a portion of said tensile rods positioned in the slots in the second block;
- and
- compacted soil, said tensile rods extending into the soil and engaged therewith at least partially by friction.
An earthen work structure, comprising, in combination:
- a plurality of facing blocks arrayed in courses, said blocks including a front wall, a back wall, opposite side walls, a top and a bottom, at least one recess in the top or bottom, said recess extending through the back wall, and a bore into the block located in the recess, and projecting into the block;
- a stabilizing element including a connection member positioned in the recess and extending outwardly from the back wall,
- a pin through the stabilizing connection member extending into the block bore to attach the connection member to the block;
- compacted soil, said stabilizing element further including a tensile member connected to the connection member, said tensile member extending into the compacted soil and engaged therewith at least partially by friction.
