摘要

A method of manufacturing a drill-injection pile with controlled broadening, including drilling a well, installing a reinforcing cage, injecting an injection solution to controlledly compressing the walls of the well along the entire length of the annulus, characterized in that the reinforcing cage is made in the form of an injector pipe with a plug at the location of the membrane-glass and two or three zones of injection holes with a diameter of 0.08-0.12 d, where d is the diameter of the well, the first zone of the holes is located on the end portion of the membrane-cup with a step of 0.5-0.6 d in a checkerboard pattern, the second is outside the end zone with equal increments of 3-6d, and the third is located in the reinforcement zone of the base material of the building under reconstruction, all perforation holes are closed with rubber cuffs 0.25-0.35d wide, and two o-rings are installed on the injector with a diameter corresponding to the diameter of the well, at a distance of 3-4d from its two ends, injection of the injection solution is carried out using a rubber hose, at the lower end of which a packer is located, and the upper end is connected to the pump station, for voevremenno possible defect detection membrane under the upper sealing ring in the pipe-injector also has a special opening.
