Abstract
Permanent concrete wall construction disposed adjacent the face of an excavation cut in the earth and having a base comprising a plurality of soil anchors extending into the earth through the face of the excavation cut. The soil anchors include reinforcing elements which have a definite lifteime in excess of 50 years. The soil anchors have proximal extremities which extend outwardly away from the face of the cut. A permanent concrete wall extending upwardly from the base of the excavation with the proximal extremities of said soil anchors being buried within the concrete wall. The concrete wall has a finished architectural surface formed as an integral part thereof.

A permanent concrete wall construction disposed adjacent the face of an excavation cut in the earth and having a base comprising a plurality of soil anchors extending into the earth through the face of the excavation cut, the soil anchors including reinforcing elements which have a definite lifetime in excess of 50 years, the soil anchors having proximal extremities which extend outwardly away from the face of the cut and a permanent concrete wall extending upwardly from the base of the excavation with the proximal extremities of said anchors being buried within said permanent concrete wall so that said anchors do not protrude through the permanent concrete wall, said permanent concrete wall being free of piles and being formed of first and second applications of pneumatically applied concrete with a bonding surface therebetween, said second application having a finished architectural surface formed as an integral part thereof said wall further comprising reinforcing elements in each of said first and second applications.
A method for forming a permanent concrete wall construction disposed adjacent the face of an excavation cut formed in the earth, comprising the steps of placing a plurality of soil anchors formed of reinforcing elements having a lifetime in excess of 50 years extending into the earth from the face of the excavation cut in such a manner so that the proximal extremities of the soil anchors extend inwardly from the face of the cut, applying reinforcing over the face of the cut extending across the proximal extremities of the soil anchors, pneumatically applying a first application of concrete to the face of the cut to cover the reinforcing elements and to cover at least portions of the proximal extremities of the soil anchors and to provide a bonding surface to provide a concrete wall with a bonding surface which forms at least a portion of the permanent concrete wall construction, pneumatically applying a second application of concrete which is bonded to the exterior surface of the first application of concrete to provide a permanent concrete wall construction having an exterior surface in which the exterior surface of the second application has an architectural finish through which the soil anchors do not protrude and placing additional reinforcing adjacent to the first application of concrete prior to the second application of concrete so that the additional reinforcing is embedded in the second application of concrete, said first named reinforcing and said additional reinforcing in combination with the first and second applications of concrete being engineered to provide the permanent concrete wall structure.
