METHOD FOR CORRECTION OF NON-UNIFORMITY OF SAG UNDER BUILDINGS AND CONSTRUCTIONS ON MAT FOUNDATIONS

摘要

A method for correction of non-uniformity of subsidence under buildings and constructions on mat foundations includes arrangement of injection conductors oriented vertically and injection of movable mortar under the part of construction in direction of tilt. Prior to injection of movable solution through conductors placed along the perimeter of the foundation to be fixed wetting of earth is performed, and than through those very conductors injection of movable solution is performed under pressure that brings about hydro-break of weakened earth, and after curing of mortar injection of movable mortar in the contour obtained is performed. Supply of movable mortar is performed through injectors under given static pressure with application to stationary flow of solution of formed additionally by means of generator of hydraulic pulses periodical pressure pulses.
