DRAINAGE SHELL RAMMING MODULE Russian patent published in 2025 - IPC E02B11/00 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to the field of hydraulic engineering and landscape improvement and can be used in drainage systems in ditches, in the drainage of foundations, retaining walls, roof drains, septic tanks, basements, and can also be used as an underground drainage system in the form of a dug drainage ditch, in which a drainage module is laid, in a shell of granulated ethylene vinyl acetate and geotextile, followed by backfilling with soil to remove excess surface layer of water and ground water from the drained surface to the discharge point. Drainage shell-type stuffing module contains shell in the form of “sleeve” filled with filler. Shell is made of geotextile material with density of 80-200 g/m², which is a filter element designed to hold the filler. Filler is granular ethylene vinyl acetate (EVA) with granule size from 2 to 100 mm. Ends of shell are clamped by clamping elements, or ends of shell are fixed on coupling element made with plug.

EFFECT: increased load capacity with simultaneous increase of carrying capacity, increased strength of drainage module.
