FIELD: construction.
SUBSTANCE: invention relates to construction of supports of high-voltage power transmission lines, in particular, to structures of V-shaped hinged supports, geometric position of which is adjusted by tension of braces. Proposed anchor support of the power transmission line contains V-shaped inclined racks resting on the surface foundation and interconnected by transverse diaphragms and cross links fixed to the strut braces, and rigid crossbar. Surface foundation is made in form of support beam arranged perpendicular to axis of crossarm. Stands made with expansion in lower part are fixed on support beam by means of two support units spaced along its length at distance of 0.8–4 m.
EFFECT: achieved technical results consists in improvement of rigidity and stability of support with respect to various loads, prevention of destruction of foundation, providing reliable and long-term operation of support, with simplicity of mounting structure.
