Claim 19:
20. A reticulated driven micropile footing system comprising:
(i) a one-piece pile cap of galvanized steel having a flat top surface and continuous peripheral sidewall descending downward to form an open shell;
(ii) embossing formed in the flat top surface of said one-piece pile cap, adapted to strengthen said one-piece pile cap against distortion;
(iii) at least three mount holes through said one-piece pile cap, adapted to provide for mounting to said one-piece pile cap;
(iv) a medial opening in said one-piece pile cap, having tabs, wherein said embossing being formed adjacent said medial opening;
(v) at least three micropiles of galvanized steel;
(vi) at least three angled guides formed in the sidewall of said one-piece pile cap and extending outwardly therefrom, said guides being adapted to guide said micropiles at a defined angle relative to the top surface of said one-piece pile cap;
(vii) at least three pile openings through the top surface of said one-piece pile cap, each through a said angled guide, adapted to allow the angled insertion of a said micropile;
(viii) upper set holes in said one-piece pile cap near said pile openings, adapted to facilitate secure fastening of said one-piece pile cap to said micropiles; and
(ix) lower set-adjust holes in said one-piece pile cap at said angled guides, adapted to facilitate a change in the angle at which said micropiles are driven.
