FIELD: building, particularly erecting bearing-enclosing structures for multi-story building in sandy, clay sandy, and yielding clay ground.
SUBSTANCE: device includes vibroexciter and at least two hollow bodies with guiders fixed to the first side walls of bodies along longitudinal axes thereof. Guiders form extensions to be inserted in corresponding slots made on another side walls of bodies. Body has flaps arranged in lower part thereof and rests for flaps. One flap is L-shaped and connected with upper part of hollow body by flexible connection. Flexible connection has upper and lower loops. The flap attached to flexible connection is installed in closed position by connecting lower loop to upper part of hollow body and in opened position by attaching upper loop to upper part of hollow body.
EFFECT: extended capabilities due to increased outlet surface for concrete mixture flow, reduced time for cementing hole excavated in ground.
