20090252561 | CONNECTION MECHANISM FOR LARGE SCALE RETAINING WALL BLOCKS - A block assembly includes integral connection mechanisms specifically designed for incorporation into engineered retaining walls. These connection mechanisms specifically accommodate the use of reinforcing grids in the formation of a retaining wall which, when used, will stabilize the retaining wall and provide additional strength. The connection mechanism is formed prior to fabrication of the block itself, and thus can be integrally incorporated during casting/fabrication of the block itself. The connection mechanism defines a connection slot usable during retaining wall fabrication (by allowing easy connection to the reinforcing grid) while also accommodating holding and lifting of the block assembly. Due to the fabrication method, the configuration of the connection mechanisms inserted into the block can be uniquely designed to provide desired physical coupling once the concrete is hardened. This further allows the use of different materials and different structures to provide the desired strength and allow the use of optimal materials. | 10-08-2009 |
