FIELD: construction. ^ SUBSTANCE: method to erect tubular drain includes making receiving part from flexible mats made of meshy shells and draining filler, which is made of tight rows of light fascines wrapped into geogrid. Flexible mats are arranged around drained perforated pipes normally to direction of filtration flow. At the distance of mats length, additionally around drained pipes, stiffening rings are arranged with height of rib that equals thickness of water receiving part, around which gabion net is tightened along whole area, and fixed to stiffening rings. Draining part is made of similar mats, but arranged at certain distance from each other in direction of filtration flow and with inclination from drained pipes to foot of downward slope. Light fascines are made of dry ripe cane. ^ EFFECT: reduced labour intensiveness of drainage arrangement and increased efficiency of its operation. ^ 5 dwg |
