DEVICE TO APPLY ANTIFILTRATION COATING Russian patent published in 2012 - IPC E02B3/16 E01C19/08 

FIELD: construction, road engineering.

SUBSTANCE: invention may be used in mining and processing industries to hydraulically insulate storages of wastes and to preserve precious components in anthropogenic massifs, and also to insulate waste banks and garbage dumps with antifiltration screens from polymer materials. The device comprises a frame platform with longitudinal beams and wheels, which is hingedly joined to a basic vehicle. Additionally it comprises a hopper with granulated wastes of polyethylene and polypropylene, an auger mechanism for supply of granules into a heating area with a controlled motor, a heater and a lining mechanism of extruder type with a metal hollow cooled roller providing for coating compaction.

EFFECT: increased reliability of a screening layer due to preparation of coating of required thickness directly in place of laying and higher operational reliability as a whole.
