FIELD: construction.SUBSTANCE: soil anchor comprises a traction rod arranged in the well and fixed to an anchor lock, made in the form of a nozzle with longitudinal slots on the part of the nozzle length at the side of the well head, with filling by the hardening solution. Diametral strips are welded to the nozzle at its side surface with continuation at both sides of the nozzle to bend the strips to the axis of the well, and the ends of strips are bent from the axis to the walls of the well. On a part of lengths of strips close to well bottomhole there are metal pads welded. An insert is brought into the inner space of the nozzle, having a central hole for passage of the noise part of a pneumodrill. Ends of strips in areas of bends are reinforced by angles. The insert may be made, for instance, from wood or plastic.EFFECT: increased bearing capacity of an anchor.2 dwg |
