In concrete pier, pier with collar, and caps with helical, rock and soil anchor foundations, a corrugation filler mold is assembled onto the outer end of horizontally extending radial bolts to be post-tensioned. The filler mold receives the bolt outer end through a hole and fits into the adjacent corrugation trough on the outside surface of a corrugated metal pipe (CMP) defining an inside and/or outside surface of the pier foundation. The filler mold forms an enclosed cavity surrounding the radial bolt which can then be filled with cementitious material. When filled and cured, the filler mold and cementitious material stabilize the radial bolt in its horizontal position and the pier foundation during and after post-tensioning.
A corrugation filler mold comprising a generally rectangular flat mold top having a generally centrally located hole sized to snugly receive an outer end of a horizontally extending radial bolt of a cementitious foundation therethrough and a pair of parabola-shaped wings extending perpendicularly from opposite sides of the rectangular flat mold top, which wings are configured to engage a corrugation of an outer corrugated metal pipe of said cementitious foundation and form a external mold cavity surrounding a portion of said horizontally extending radial bolt outside said corrugation.
A method for stabilizing the outer end of a horizontal radial bolt extending through a corrugation trough of an outer corrugate metal pipe of a cementitious foundation, the method comprising:
