FIELD: construction.
SUBSTANCE: method of fabrication of root anchor piles with controlled widening includes well drilling, installation of an anchor in the form of tube-injector, injecting of the injection solution until controlled compression of borehole walls over the entire length of the annulus. The controlled widening is reinforced by sickle-curved rods, located along the perimeter of the bottom of the injector inside fixed rubber membrane barrel.
EFFECT: increase of bearing capacity of anchor piles, fabricability improvement, decrease of required immersion length.
