FIELD: construction. ^ SUBSTANCE: invention is related to construction and mining, to subsurface anchors for fixation of frames and structures to surface, for support of pit edges, etc. Anchor comprises anchor plate, flexible traction rod and unit for fixation to this plate, which is arranged in the form of through openings made in anchor plate. Lock end of flexible traction rod is pulled through them, starting from the inlet opening. Inlet opening is located along axis of symmetry of anchor plate and is displaced from centre of gravity of specified plate to the side of its leading end at the distance equal to 0.10.3 of distance between them. ^ EFFECT: simplified design, improved bearing capacity of subsurface anchor and efficiency of its submersion in soil due to direct connection of flexible traction rod with anchor plate. ^ 2 cl, 2 dwg |
