In order to speed up consolidation, vertical drainage has proven to be a good option for the construction of modified bases . A set of experimental field studies was conducted to study the influence of self-forming vertical sand drains on the process of consolidation of water -saturated soil. Experimental equipment for the construction of vertical sand drains for work in Western Siberia has been developed.
