FIELD: construction.
SUBSTANCE: method for erection of combined drain of biopositive design includes banquet and inclined drains. Inclined drain and water-receiving part of banquet drain are made of flexible mats comprising tight rows of light fascines wrapped in geonet and laid normally towards filtration flow. Banquet prism of drain is erected from gabion mats, filler of which is made of light fascines and perforated pipes laid in alternating rows and wrapped in gabion net. Gabion mats are laid in foundation and on collar of banquet prism normally towards filtration flow, and in prism body - along with filtration flow. Binding rings of reinforced wires are arranged in areas around banquet prism of gabion mats and fixed to anchors arranged over inclined drain at the distance from each other.
EFFECT: improved operational reliability of structure and recovery of green areas along water edge in lower ponds of soil structures.
