METHOD FOR CORRECTION OF VERTICAL POSITION OF BUILDINGS AND STRUCTURES ON PANEL-WALL FOUNDATION Russian patent published in 2009 - IPC E02D35/00 

FIELD: construction.

SUBSTANCE: method for correction of vertical position of buildings and structures on panel-wall foundation. Vertically oriented injection conductors are installed in slab body with elevation of one end above the upper cut of slab or level of subgrading and deepening of the other end in soil under foot or slab foundation mattress, through which movable mortar is injected under part of building in direction of careen till supply pressure increases by 40-50% relative to working pressure or until movable mortar flow increases in volume of 2 m³ in one injection horizon. Number and altitude position of injection horizons are assigned according to data of geological engineering survey and are clarified according to results of measurement of rate of injector submersion in soil. Necessity of injection works performance is determined by materials of geodesic survey over building or structure in process of construction and during the first years of operation.

EFFECT: reduced labour intensiveness during works performance, increased reliability of injection method application, increased operational reliability of buildings and structures on panel-wall foundations.
