POST-TENSIONED HELICAL ANCHORS SIMULTANEOUSLY SPIN-DRILLED AND GROUTED AND METHOD THEREFOR

An assembly and method of simultaneously spin drilling and pressure grouting a helical anchor into the ground vertically, horizontally or at an inclined angle create a continuous grouting configuration inside and outside the helical anchor for its entire depth in the ground. The helical anchor is co...

description	An assembly and method of simultaneously spin drilling and pressure grouting a helical anchor into the ground vertically, horizontally or at an inclined angle create a continuous grouting configuration inside and outside the helical anchor for its entire depth in the ground. The helical anchor is configured to be partially or completely removed as desired and can be provided at its upper end with a tensioning element to post tension a cementitious foundation structure. A unique spin drilling and grouting assembly continuously provides grout under pressure to the interior of the helical anchor during its spin drilling into the ground. In one embodiment, the pressure grouted helical anchor is used with an upwardly extending tensioning element to reinforce cementitious foundation caps or other concrete support foundations.
