FILTERING WATER PASSAGE STRUCTURE Russian patent published in 2020 - IPC E02B8/02 E02B3/10 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in construction or reconstruction of embankment of linear structure with device of water-passage structures at crossing of water streams with low flow rate. Water passage structure consists of the body of embankment 2, of culvert pipe 1 located in the lower part of the body of the embankment, which crosses it in the transverse direction, of the inlet and outlet headings, and of the draining material. Inlet and outlet headings of the water-passage structure are equipped with replaceable filtering elements 6 made of a metal frame with a grid, which are filled with drainage material, in form of a special filtering natural sorbent, for example, schungite or zeolite.
