Abstract
An improved tower foundation is provided which is inexpensive to manufacture and when installed, serves to securely support a leg of power transmission towers and the like. The tower foundation hereof includes a screw-type earth anchor member having a tubular cavity at the uppermost end thereof. An elongated tower leg connector member is positioned and secured in the cavity of the installed anchor by an initially flowable, solidified material (preferably a sand/epoxy resin mixture). The tower leg connector member advantageously comprises a lowermost, tubular first portion and an uppermost, L-shaped in cross-section second, apertured connection portion, with the first and second portions having approximately coincidental centroidal axes. Preferably, the tower leg connector member is positioned in the cavity prior to setting of the solidifiable material, and can be adjusted as necessary for proper alignment and securement thereof to the tower leg, thereby compensating for slight anchor member installation error.
