FIELD: construction.
SUBSTANCE: drainage device consists of coupled drainage perforated pipes with figure cover arranged over them, having transverse ledges at the lower side, and filtering fill. Cover is arranged with semi-cylindrical shape from fixed halves of recycled tyres. Transverse ledges formed by side flanges of tyres form a vault over pipes, height of which equals half of coupled pipes width.
EFFECT: invention makes it possible to simplify and make drainage device cheaper, to increase its resistance to deformations of surrounding soil medium.
