Abstract
A retaining wall comprises a precast concrete face panel with integral counterfort connected to the rear of the facing and a precast concrete base supporting the facing and the counterfort. The counterfort comprises a reinforced concrete slab having a substantially vertical front portion at a substantially right angle to a base portion, and a rear portion running from substantially the top of the counterfort to the rear of the base portion thereof. The face and counterfort module is connected to the base module through the use of rebar and openings which are fixedly attached together using a high strength group.
Claims26
A precast concrete retaining wall assembly comprising:
- a first module comprising a precast concrete face panel and at least one integral counterfort, wherein said first module includes reinforcement bars;
- and
- a second module comprising a substantially solid precast concrete base platform, wherein said second module includes reinforcement bars.
A method for installing a precast concrete retaining wall assembly which includes a first module comprising a precast concrete face panel and at least one integral counterfort, wherein said first module includes reinforcement bars, and a second module made of a precast concrete base, wherein said second module includes reinforcement bars and wherein one of said first module or second module further comprises a plurality of said reinforcement bars, each with an exposed end portion protruding from an outer surface and the other module further comprises at least one opening sized to receive said exposed end portion of said reinforcement bars, the method comprising the steps of:
- placing the second module into a generally horizontal position;
- placing the face of the first module in a generally vertical position and raising said first module above said second module;
- aligning the exposed ends of the reinforcement bars of the selected first or second module with the at least one opening of the other module;
- placing at least one shim on top of the second module;
- moving the first module on top of the second module such that the exposed ends of the reinforcement bars of the selected first or second module are placed within the openings in the other module;
- adding grout into said openings;
- and
- backfilling the space behind the precast concrete retaining wall assembly.
A precast concrete retaining wall assembly comprising:
- a first module comprising a precast concrete face having opposed top and bottom surfaces, opposed side surfaces, opposed front and rear surfaces, and at least one integral counterfort integrally attached to the rear surface of the face, wherein said counterfort further comprises at least one side surface and at least a bottom surface, wherein said first module further includes reinforcement bars;
- and
- a second module comprising a precast concrete base having opposed top and bottom surfaces, opposed side surfaces and opposed front and rear surfaces, wherein said second module further includes reinforcement bars.
