ABSTRACT:
A replacement earth retaining wall and a method for modifying, repairing, or replacing an existing earth retaining wall is disclosed. The replacement wall includes a reinforced concrete facing, and soil nails or tiebacks with specially fabricated anchorhead assemblies. The structure includes a concrete panel cast adjacent the face of an existing retaining wall such as a corrugated bin type wall. Tiebacks or soil nails are installed through the existing wall and are encased in the reinforced concrete panel. During construction, tiebacks, where used, are installed through the existing wall and are tensioned against the front face of the existing wall before the concrete panel is cast. The concrete panel is supported by and encases the anchorhead assemblies and covers the outer face of the existing wall. The anchorhead assembly includes a load distribution member, a tube, and tension studs extending from the load distribution member.
