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.

Description

FIELD OF THE INVENTION

[0001] The present invention pertains generally to retaining walls. Specifically, the invention relates to an apparatus and method of installation for a completely precast concrete retaining wall of the type typically used alongside highways and railways.BACKGROUND OF THE INVENTION

[0002] Various retaining wall systems have been developed for use in retaining soil on an embankment. In a conventional retaining wall design, one of the major design criteria that must be considered is the pressure exerted on the foundation at the front of the base (toe) of the retaining wall system. This becomes particularly limiting in tall vertical walls with sloping backfill. Conventionally designed cantilevered walls reduce the pressure at the toe by providing a lever arm perpendicular to and behind the wall face upon which the vertical load of the backfill acts, creating a moment opposite in direction to the moment due to the horizontal force of the backfill material on the wall ...
