ABSTRACT:
A method of progressively erecting a wall below earth grade as excavation of the volume to be walled is accomplished. Initially, a plurality of spaced, generally vertical, holes are drilled in the earth to the full intended wall height along edges of the intended excavation plus an embediment amount at the lower end. Parallel soilpier beams are secured in each hole, preferably by filling the hole around each soilpier beam with lean concrete. The interior area is incrementally excavated, including the earth between the soilpier beams, to a selected depth. After the lean concrete on at least the sides of the soilpier beams in line with other soilpier beams is chipped away to the selected incremental excavated depth, structural panels having heights substantially corresponding to the excavated depth are placed between the soilpier beams and secured to the soilpier beams. Incremental excavation is continued and panels are installed in series until the desired full depth is reached. Preferably, the soilpier beams are metal and the panels are structural concrete with metal strips secured vertically near the panel edges, so that the panels can be secured to the soilpier beams by welding brackets between soilpier beams and strips. Pins may be provided between abutting edges of adjacent panels. Concrete grout may be introduced into spaces between panels and soilpier beams and between panels and the surrounding earth to further strengthen the structure.
