ABSTRACT:
A precast concrete pile and cofferdams, etc., made therefrom, employing a new method. A rectangular main stem extends from the top to the bottom of the pile, a lower portion of the pile consisting exclusively of the main stem. An upper portion of the pile incorporates, integrally with the stem, a pair of generally rectangular flanges each extending out from one of two opposing faces along one edge of the stem and set back from the opposite edge. The piles may be driven next to each other, with the flanges of successive piles overlapping, to make a continuous cofferdam or retaining wall, especially well suited for bridge piers.
