METHOD TO ERECT EMBANKMENT ON FROZEN SOILS Russian patent published in 2012 - IPC E01C3/06 

FIELD: construction.

SUBSTANCE: in the method to erect embankment on frozen soils, according to the invention, a finished frozen dry soil and cement mixture is produced in winter, for this purpose a frozen highly icy soil is used, which is crushed - ground to produce frozen crumbs, and a binder, for instance, cement, which are mixed, stacked, and the finished frozen (dry) soil and cement mixture is filled into an embankment in winter. At first the dry fiber-reinforced cement mixture is prepared from cement and fiber, stacked, afterwards a finished frozen (dry) mixture is prepared from a dry fiber-reinforced cement mixture and a ground frozen soil, and laid into an embankment. The finished frozen dry mixture is prepared from a crushed frozen soil and an expanding cement, in the amount complying with the change of its volume during expansion in process of hydration and equal to the volume of ice in the frozen crushed soil. The dry cement and sand mixture is prepared from cement and dried (conditioned) sand, stacked, then the finished frozen dry mixture is prepared from a dry cement and sand mixture and a ground frozen (finely dispersed) soil, besides, the volume of (conditioned) sand is equal to the volume of cavities between grains of the ground frozen soil, afterwards the prepared finished frozen (dry) mixture is laid into the embankment.
