IN SITU REINFORCED STRUCTURAL DIAPHRAGM WALLS AND METHODS ON MANUFACTURING ABSTRACT OF THE DISCLOSURE The present invention is directed to in situ structural diaphragm walls and methods for constructing such walls. The structural diaphragm walls of the present invention are comprised of a series of small and large-diameter soilcrete columns configured such that the small-diameter columns alternate with the large-diameter columns. A structural member, such as a steel I-beam, is placed within each of the small-diameter columns or within each of the large diameter columns, depending on the structural requirements of the resulting diaphragm wall. The structural diaphragm wall is capable of withstanding the lateral forces which may be imposed by soil or water. Thus, the wall is ideally suited for construction applications when ground water must be restrained or when soil adjacent an excavation site is in danger of crumblingbecause of the loss of the lateral support which existed prior to excavation. The method of constructing the structural diaphragm wall involves employing a three-shaft auger machine to construct a series of soilcrete columns. Before the soilcrete mixture cures, the structural diaphragm wall may be alligned with the column and directed into the column, usually under its own weight. The soilcrete mixture is then allowed to cure, resulting in the reinforced structural diaphragm wall of the present invention.
