FIELD: construction.SUBSTANCE: method includes formation of a well, placement of a stretching tight shell in it and supply of sealing substance. The well is formed by driving a pipe with a plug at the end and a stretching tight shell on the outer surface into soil. The sealing substance is supplied into the specified shell via longitudinal slots made in the pipe. The device comprises a working organ and a facility of impact load application to it, comprising a pipe, where a rod is inserted as capable of longitudinal displacement in it and contact with the working element. The stretching tight shell is placed onto the pipe and fixed, and longitudinal slots are made underneath in the pipe. The working element is made in the form of a rod, forming a plug, with a cone-shaped tip at the end and inserted into the guide pipe as capable of limited longitudinal displacement in it. The rod comprises an accessory to prevent fallout from the pipe, and its cone-shaped tip protrudes from the pipe.EFFECT: increased density of soil by introduction of a stretching tight shell into it, expansion of device capabilities for creation of a pile with a support in a base.8 cl, 2 dwg |
