SEPARATING PILE WITH STRESS CONCENTRATORS Russian patent published in 2000 - IPC

FIELD: civil engineering, particularly, pile foundation; applicable in construction of foundations on inclined piles. SUBSTANCE: separating pipe with stress concentrators includes reinforced concrete stem rectangular in cross-section and having triangular recesses on point and two side surfaces used as stress concentrators, and guide wedge. Inclined piles are made as an integral member with internal cavity filled with incompressible liquid - water designed for uniform supply of pressure to places of stress concentration. In the course of sinking, reinforced concrete stem separates into two inclined piles. For pile sinking, no complete equipment is needed. EFFECT: higher efficiency of production of pile structures and their transportation and storage. 1 cl, 4 dwg
