FIELD: construction.
SUBSTANCE: invention relates to construction, namely to construction of pile foundations using combined piles. Combined pile includes a well in the ground, a drilling concrete pile and a driven pile immersed in the ground through the body of the concrete pile. Driven pile is submerged into the borehole of the drilling pile formed in the soil, made of concrete, or cement mortar, or cement soil, with a diameter equal to or greater than the diagonal of the square cross-section or more by 10 cm and more than the diameter of the round cross-section of the driven pile, wherein driven pile point is located irrespective of shaft heel position.
EFFECT: increasing bearing capacity of combined pile and facilitating immersion of driven pile into sandy, gravelly and subsidence soils, as well as reducing material costs for its device.
