FIELD: construction.
SUBSTANCE: method of manufacturing a drill-driven pile includes drilling a leader well of radius R0 in the soil, filling a part of the well with hardening grout, followed by inserting the pile in the wellbore up to the design mark. The pile is inserted under the action of a static load, and the radius of its upper part is chosen taking into account the ratio 1.2R0<R1<1.6R0.
EFFECT: increase of bearing capacity of the pile, increase of manufacturability, reducing the cost, material consumption and the foundation construction time, reducing negative impacts on the soil of the foundation and the structure of the building, increasing the accuracy of its implementation.
