ANTI-FILTRATION LARGE-CAPACITY COATING BASED ON RECYCLED RAW MATERIAL OF DRIP LINES Russian patent published in 2025 - IPC E02B3/16 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering and reclamation construction and can be used in arrangement of impermeable coatings from polymer materials on irrigation channels and reservoirs. Anti-filtration coating includes flexible sheets made of composite material based on crushed easily processed polyethylene wastes. Anti-filtration coating is made in the form of flexible sheet material 1 of spent drip lines with thickness of 0.3 m, volumetric geonet 3 with height of 0.24 m, filled with crumbs from spent drip lines 4, on top of which there is another layer of flexible sheet material 1 of spent drip lines. Layers of the anti-filtration coating are connected to each other by means of a hot press. Upper part of the coating is treated with vacuum ultraviolet radiation 2. Anti-filtration coating is made in the form of sheets with thickness of 0.03 m, width of 3.0 m, and length of 3.0 m. Grooves for connection of separate coating sheets are made in the form of a lock with click system 5 and joints are treated with liquid rubber 6.

EFFECT: development of effective anti-filtration coating from drip line wastes.
