Claim:
A reinforced-concrete column in a soil pit comprising a reinforcing cage making monolithic with concrete mix and inserts, said reinforcing cage having an upper bearing and a lower foundation parts, wherein the column is made in a non-removable casing in a single- or multi-silt pit in soil, the upper part of the reinforcing cage is arranged in the non-removable casing with a closed-type contour, projection of geometrical center of a cross-section of which is combined with projection of geometric center of a cross-section of the lower foundation part of the reinforcing cage, sizes of branches of the lower part of the reinforcing cage along axis Y are taken with a proviso that: A K i<A B i by value Ω y =2(ε y +α y +β y ), where Y—axis passing through geometric center of section of the cage lower part; A K i—basic sizes of the branches of the lower part of the column cage along axis Y; A B i—basic sizes of pit slits along axis Y corresponding to them; K —index of a size related to the cage; B —index of a size related to the pit-slit; i—size index; ε y —component of eccentricity along axis Y of projection of geometric center of the reinforcing cage of the column relative to projection of its center of masses in the plane of its top; α y —maximum deviation of the pit from vertical along axis Y; β y —deviation of geometric center of cross-section of the pit in plane along axis Y in the plane of the column top; sizes of the branches of the lower part of reinforcing cage along axis X are taken with the proviso that: B K i<B B i by value Ω x =2(ε x +α x +β x ), where X—axis passing through geometric center of cross-section of the cage lower part perpendicular to axis Y; B K i—basic sizes of the branches of the column cage lower part along axis X; B B i—basic sizes of the pit slits along axis X; ε x —component of eccentricity along axis X of projection of geometric centre of the reinforcing cage of the column relative to projection of its centre of masses in the plane of its top; α x —maximum deviation of the pit from vertical along axis X; β x —deviation of geometric center of the pit cross-section in the plane along axis X in the plane of the column top, and the inserts are arranged in the column upper bearing part at the levels of marks of the foundation slab and marks of floor slabs and made in form of closed-type contours with stiffening ribs.
