Abstract
Abstract This invention relates to a pile structure and the method of forming a pile structure in situ which includes a pile having an annularly shaped band portion mounted adjacent the lower end thereof that supports an annular manifold on its upper surface, the manifold having a plurality of spaced upwardly directed nozzles. Grout tubes extend from near the top end of the pile downwardly adjacent the pile walls to the manifold. When the pile is driven into the earth, grout is simultaneously forced through the grout tubes into the manifold and upwardly out through the plurality of nozzles to completely fill the annular space between the walls of the pile and the adjacent earth. Upon completion of the driving operation, the flow of grout is terminated and the grout is allowed to set-up and form a bonded interface between the pile and the adjacent earth.
