FIELD: construction.
SUBSTANCE: method to increase bearing capacity of concrete-pipe structures consists in arrangement of anchors inside a metal pipe with further filling with a concrete mix. Anchors are pressed into the metal pipe via holes. Holes are arranged along mutually perpendicular axes with a pitch along the vertical line equal to the anchor length.
EFFECT: increased bearing capacity of concrete-pipe structures by increasing adhesion of concrete with inner surface of the metal pipe.
