Retaining wall block system

Abstract

A wall block having a block body having opposed front and rear faces, opposed first and second side walls, and opposed and substantially parallel top and bottom faces, one or more pin holes that open onto the top face of the block, and one or more lugs that extend from the bottom face, each lug having a back surface that extends contiguously from the rear face of the block. A corner block for use with the wall block. A retaining wall comprising a plurality of wall blocks including at least one lower course and at least one upper course.

Description

[0001]This application claims the benefit of U.S. Provisional Patent Application No. 61 / 309,650, filed Mar. 2, 2010, entitled “Retaining Wall Block System”, the contents of which are hereby incorporated by reference herein.FIELD OF THE INVENTION[0002]This invention relates generally to retaining wall blocks and retaining walls constructed from such blocks. In particular, this invention relates to a retaining wall block system having a dual connection feature that allows the connection of blocks in the wall using a pinning system and / or a lug system. The pinning system is used to interconnect blocks in upper and lower courses and additionally used as a geogrid soil reinforcement connection element. The lug system is used to connect and align blocks by course. The pinning and lug systems prevent block displacement from retaining forces and enhance the structural integrity of the retaining wall constructed.BACKGROUND OF THE INVENTION[0003]Retaining walls are used in various landscaping...

AI Technical Summary

Benefits of technology

[0016]The present invention relates to a method of constructing a retaining wall having a dual connection feature that allows the connection of blocks in the wall using a lug system and / or a pinning system. The lug system is used to connect and align blocks by course. The pinning system is used to interconnect blocks in upper and lower courses and is additionally used as a geogrid soil reinforcement connection element. The pinning and lug systems prevent block displacement from retaining forces and enhance the structural integrity of the retaining wall constructed.

Problems solved by technology

Again these walls will be limited in height due to the minimal connection strength of the lip and geogrid and the potential for the lips to abraid and cut the geogrid.

These blocks are not generally desirable for use in taller retaining walls where soil reinforcement with a positive connection to the wall is necessary.
