METHOD TO ERECT RECESSED STRUCTURES AND UNDERGROUND STRUCTURES OF BUILDINGS Russian patent published in 2013 - IPC E02D29/00 

FIELD: construction.

SUBSTANCE: method to erect recessed structures and underground structures of buildings realised by submersion of a drop caisson into soil by means of soil excavation in the caisson cavity, leaving support zones near the knife part, in order to provide for the possibility to control the submersion process, before submersion of the caisson along its perimeter they arrange soil anchors with anchor traction rods, anchor traction rods are pulled in caisson walls, connected with jacks, installed on the caisson walls, afterwards tier-by-tier pressing of the caisson is carried out with simultaneous withdrawal of soil from the cavity and control of tension of anchor traction rods. Anchors and anchor traction rods are arranged in through longitudinal holes in caisson wells in 90 degrees, and in intermediate sectors after every 18 degrees they install vertical tubular channels in process of concreting, and in these channels they move vibratory grabs with cylindrical soil snappers, and soil is excavated in turns.

EFFECT: complex increase of safety of technology of erection of underground and recessed structures, increased efficiency, reduced material intensity.
