FIELD: construction.
SUBSTANCE: invention relates to construction, to systems of external drainage for removal and export of water from pitched and straight roofs of buildings and structures. Device of vortex gutter for removal of water from roof includes pipes bent in form of spiral around vertical axis, and connected to them water intake funnels, swirled into spiral configuration. Inside the pipes there is a high standing foil designed to swirl the water flow along the central axis.
EFFECT: wider range of technical means, particularly improved drainage systems.
