FIELD: building, particularly enlargements of piles built in soft ground.
SUBSTANCE: method involves drilling well for pile body, excavating ground in pile enlargement areas with forming depressions in well wall, wherein depression shapes correspond to that of enlargements; concreting well and formed enlargements. Surfaces of each depression are reinforced during forming thereof by initial deepening support members in ground around well perimeter so that support members are located in plane corresponding to upper enlargement surface. Distance between support members prevents ground caving into space between adjacent support members. After ground excavation cross-bars are arranged between lower depression surface and support members. Cross-bars have pads connected to bases thereof.
EFFECT: increased pile enlargement quality along with improved operational reliability thereof.
