Abstract
A temporary anchor for securing part of a structure to the earth includes a tension member made up of at least two complementary shaped parts forming a regular shaped exterior. One or more ribs are formed on the exterior peripheral surface of each part so that it can be engaged within a settable grout material when it is inserted into a borehole formed in the earth. A spacer member is positioned between facing surfaces of the tension member parts and holds them in spaced relation along the length of the parts within the borehole. The spacer member is removable from between the parts when they are anchored in a grout substance so that the parts can then be removed by exerting a pulling force on them. The dimension of the spacer member between the facing surfaces of the parts is at least equal to the dimension of the ribs outwardly from the parts, whereby upon removal the spacer member leaves an open space within the borehole sufficient for the part to move inwardly with its rib being fully displaced from the grout substance for removal of the part out of the borehole.
