FIELD: construction.SUBSTANCE: foundation for a pillar or a structure of tower type includes an upper shell in the form of a truncated cone that expands towards the base. In order to increase bearing capacity of the foundation, the upper shell is made on support lower shells connected in the upper part, which are made in the form of an inner cylindrical and outer shell in the form of a truncated cone, which expands towards the base, made with a ledge in the lower part below the inner cylindrical shell by 0.1 of the foundation diameter, and having an angle of inclination to the vertical line of the inner side, which is equal to the angle of the inner friction of the foundation soil. In the inner part of the shells there are materials in the form of soil and cement soil of different strength and under different angle.EFFECT: increased bearing capacity of a foundation, reduced labour intensiveness and material intensity.2 cl, 2 dwg |
