Method for reinforcement of basement of building includes lowering through leading well of assembled piles with pressing under existing basement from niches formed in piers of basement through cutting those, arrangement of grillages in niches through installation there of reinforced frames, with fixation of casing and filling niches with concrete on cement that expands. For possibility of reinforcement of basement of building through niches with height enough for placement of units that includes distribution beam and pressing device only, assembled pipe is lowered with pressing unit through hollow guide standpipe mounted to leading well with mechanical connection of sections of pile in guide standpipe by means of conical stepped rods. The rods are preliminarily fixed to the lower filling built-up section and under effect of pressing device with conical surface of rods one presses out elastic rings that are in free way placed in slots of stoppers fixed to the upper built-in previously elongated section. |
