FIELD: civil and industrial building, particularly to erect piles adapted for new building erection and reinforcement of foundation of building to be reconstructed or repaired in soft ground. ^ SUBSTANCE: method involves forming well in ground by forced ground pressing to well walls without ground removal from well, wherein the well is created with the use of drilling string provided with tip to be left in well; supplying hardening material simultaneously with tip deepening in ground; forcing hardening material into well walls; creating excessive pressure in soft ground zones. Drilling string comprises drilling rods with separate auger sectors. Drilling string section near tip is made as auger. Tip includes conical and cylindrical rollers fixedly connected with each other. ^ EFFECT: increased load-bearing capacity of the pile, possibility to use the pile for foundation reinforcement. ^ 3 dwg |
