FIELD: construction. ^ SUBSTANCE: device to ram pits for foundations includes a cylindrical vessel with a tail in the upper part, the lower part of which is made in the form of a truncated cone with a large lower base, having channels along the perimetre that expand upwards and a transition part with a cross section, which is smaller than the cross section of the cylindrical vessel, where a tip is installed, as well as a calibrating element arranged in the form of semicircles installed as capable of rotation along a vertical line. The tip is made as movable and capable of displacement along a vertical line and is hingedly connected to the calibrating element, which has channels expanding outside in the upper part. ^ EFFECT: higher efficiency, reduced energy intensity of a device. ^ 2 cl, 4 dwg |
