Cantilevered Wing Wall

摘要

The present invention relates generally to precast cantilevered retaining walls and methods of using and forming precast cantilevered retaining walls. More specifically, the present invention relates to a cantilevered concrete retaining wall having a base shear key and blockouts for receiving a material that substantially impedes the wing wall from sliding or other inadvertent movement, to a method of retaining a soil embankment with a cantilevered concrete retaining wall, and to a method of manufacturing a precast concrete cantilevered retaining wall.

主权项

1. A precast cantilevered concrete wing wall adapted to retain a soil embankment, comprising:
a stem of a predetermined height, length, and thickness; a footing connected at a substantially right angle to the stem, the footing having a toe extending laterally from a front face of the stem and a heel extending laterally from a back face of the stem, wherein the toe, the stem, and the footing are formed as one integral piece without joints; a base shear key positioned proximate to the heel and extending in a downward direction from a horizontal plane defined by the footing to a predetermined depth, wherein the base shear key is adapted to extend into a trench excavated to receive the base shear key; and at least one blockout formed through the footing and positioned proximate to the base shear key, wherein a grout material can be injected through the at least one blockout to contact the base shear key and fill at least a portion of the trench to provide additional support and to anchor the precast cantilevered wing wall to the surrounding soil.
