FIELD: construction.
SUBSTANCE: invention is related to construction, in particular to methods for erection of piles and may be used in industrial and civil construction. In order to solve technical objective, in method of bored pile erection, including well boring, concreting of pile shaft, according to invention, after well 1 creation, multiple drilling is performed lower than well bottom by dredger with hollow bar and cutting tip 2 with simultaneous injection of strengthening mortar and development of reinforced soil mass 3, dredger is extracted, pile shaft 5 is reinforced by frame 4 and concreted.
EFFECT: lower labour intensiveness of works.
