WebThis document draws extensively from the FHWA-DP-68-IR (1988) design manual in describing issues such as subsurface investigation and laboratory testing, basic anchoring principles, ground anchor load testing, and inspection of construction materials and methods used for anchored systems. WebA helical anchor is similar to a wood screw, one obvious difference being that the helical anchor has widely-spaced discontinuous threads. Helical anchors are screwed into the ground making sure they penetrate at a rate of about one pitch length (3 inches) per revolution. There are two ways helical anchors can be installed; one of them is using
