RESEARCH THE DEFORMATION OF THE FOUNDATION BASE STRENGTHENED IS SOIL-CLAY ? CEMENT PILES IN SANDY SOIL

This paper presents the results of physical modeling and laboratory studies of deformation sandy foundation base in the natural and water-saturated state, both before and after fixing his clay ? soil-cement mixture. The basis of the method of fixing the weak sandy base put in the laboratory method of mixing drilling with vertical elements of the device in the form of micro-piles that increase strength and deformability parameters of the soil supporting layer base. Such fastening is regarded as a publication providing high quality base through the device as a composite base fastening is a focused character. . To create a fixed element used clay - cement - silicate solution, which is mixed with the soil by drilling. Сonfirm that I received new material from the soil - clay - cement, has high compressive strength, have a low modulus of deformation and reduced water permeability.
