Anchor blocks
Ground anchors are anchoring elements formed in the ground that consist of a strand bundle or steel rod surrounded with cement grout. Their role is to absorb tensile forces according to the longitudinal axis. The required anchor force is supplied by slide resistances between the ground on the one hand and an anchor body (root) on the other hand. Anchors are typically pre-stressed so as to limit the deformation of the structure whose stability they ensure.
