An earth mass forming an embankment, bridge abutment or the like has a facing of light concrete panels from which steel rods project into the earth mass, the ends of the rods being bent in one direction and then the other (in the same plane) to form anchors which will oppose thrust on the facing but will permit deposition of earth fill in layers with each layer capable of being readily compacted without interference from the anchors. The rods extend through the panels in extended slots to accommodate earth settlement and are secured thereto by nuts. The facings are desirably lap jointed laterally and the anchors extend through adjacent overlapping portions. |
