Rock Anchors generally consist of steel elements grouted in a drilled hole. The bars or strands are subsequently tensioned. Rock anchors are designed for anchoring. They are constructed of a threaded rod with integral eye and two opposing wedge halves. The anchor is placed in a hole pre-drilled in the rock, locking the anchor in place, Rock anchors are used in civil and mining structures existing concrete structures. Rock anchors are made of high tensile steely means of high strength grouting for foundations and through holes drilled into or through a structure for post-tensioning applications. For most applications the rock anchors are tensioned to a force higher than what is necessary to resist the foundation uplift force. However rock anchors may be grouted in two steps to allow. Rock anchor is a high strength steel tendon, fitted with a stressing anchorage at one end, the rock anchor tendon is inserted into a prepared hole of suitable length and diameter, Where the Rock Anchoring Service System is used in applications with rock at the surface, without coring requirements. The drilled Hole size is determined by the design loading. The hole is drilled to the desired System depth. The spreading/spinner apparatus is attached and centered in contact with the surface.
