FIELD: construction.
SUBSTANCE: invention relates to field of hydrotechnical, reclamation, aquicultural construction for horizontal drainages fitting out. Filter is made from round cross-section rods, installed along generatrix along filter axis, connected by stiffness rings from polypropylene, and on outside has water receiving surface from basalt fiber based filtering mats. Frame forming rods and filtering mats of individual links are “overlapped” interconnected with application of “Sprut” glue with formation of continuous water receiving surface.
EFFECT: increasing of filtration efficiency by creating of drainage waters reception continuous uniform front.
