Block for a retention wall of leaning type, retaining wall constructed with blocks therefor, and methods for the preparation and construction thereof

A retaining wall of a leaning type comprising:

• a plurality of rows of blocks, said rows of blocks being disposed on top of one another, each block comprising a front wall having an upper portion and a lower portion, the front wall leaning gradually in a backward direction from the lower portion to the upper portion, a bottom plate connected integrally to the lower portion of said front wall and extending backward from a rear portion of said front wall, and a partition wall extending vertically and integrally along the rear portion of the front wall, a bottom side of the partition wall being disposed integrally with the bottom plate;
• wherein at least one of the front wall and the partition wall is provided with an opening which extends vertically over an entire length thereof and into which a reinforcement rod is disposed;
• wherein a first set of rods is embedded inside the front wall in vertical and transverse directions;
• wherein a second set of rods is embedded inside the partition wall in vertical and transverse directions;
• wherein a third set of rods is embedded inside the bottom plate;
• wherein, for each block, the partition wall is connected to the rear portion of the front wall such that a top edge of the partition wall is lower than a top edge of the rear portion of the front wall so as to form a top step portion and the bottom plate is connected to the rear portion of the front wall such that a front edge portion of the bottom plate projects downward from a bottom edge of the front wall so as to form a bottom step portion;
• and
• wherein the top step portion of a block in a lower row is adapted to mate with a bottom step portion of a block in an upper row disposed on top of the block in the lower row to prevent the blocking the upper row from sliding forwards relative to the block in the lower row.

A method for the preparation of a block comprising a front wall having an upper portion and a lower portion, the front wall leaning gradually in a backward direction from the lower portion to the upper portion, a bottom plate connected integrally to the lower portion of said front wall and extending backward from a rear portion of said front wall, and a partition wall extending vertically and integrally along the rear portion of said front wall, a bottom side of said partition wall being disposed integrally with said bottom plate, wherein at least one of said front wall and said partition wall is provided with an opening which extends vertically over an entire length thereof and which is adapted to receive a reinforcement rod therein, wherein a first set of rods is embedded inside said front wall in vertical and transverse directions, wherein a second set of rods is embedded inside said partition wall in vertical and transverse directions, and wherein a third set of rods is embedded inside said bottom plate, said method comprising the steps of:

• pouring a partial amount of a material for structuring said block into a mold;
• disposing said reinforcement rod in said material;
• and
• pouring another partial amount of said material into the mold.

A method for the construction of a retaining wall of a leaning type with a plurality of rows of blocks, said rows of blocks being disposed on top of one another, each block comprising a front wall having an upper portion and a lower portion, the front wall leaning gradually in a backward direction from the lower portion to the upper portion, a bottom plate connected integrally to the lower portion of said front wall and extending backward form a rear portion of said front wall, and a partition wall extending vertically and integrally along the rear portion of the front wall, a bottom side of the partition wall being disposed integrally with the bottom plate, wherein at least one of the front wall and the partition wall is provided with an opening which extends vertically over an entire length thereof and which is adapted to receive a reinforcement member therein, wherein a first set of rods is embedded inside the front wall in vertical and transverse directions, wherein a second set of rods is embedded inside the partition wall in vertical and transverse directions, wherein a third set of rods is embedded inside the bottom plate, wherein, for each block, the partition wall is connected to the rear portion of the front wall such that a top edge of the partition wall is lower than a top edge of the rear portion of the front wall so as to form a top step portion and the bottom plate is connected to the rear portion of the front wall such that a front edge portion of the bottom plate projects downward from a bottom edge of the front wall so as to form a bottom step portion, and wherein the top step portion of a blocking a lower row is adapted to mate with a bottom step portion of a block in an upper row disposed on top of the block in the lower row to prevent the block in the upper row from sliding forwards, said method comprising the steps of:

• forming a footing foundation at a construction site where said retaining wall is constructed;
• laying a lowest row of said blocks onto an upper rear surface of the footing foundation;
• laying an upper row of said blocks onto the lowest row of said blocks;
• laying another row said blocks onto the lower row of said blocks;
• and
• laying a further row of said blocks onto the another row of said blocks.
