FIELD: collection and removal of liquids.
SUBSTANCE: channel comprises one or more main section (1) providing a channel length including upper (2) and lower (3) parts, where upper part comprises two or more longitudinal channels (4), which are located next to each other and have at least one common side wall (5). Upper part of the section is open and does not include the protective grid from above. Lower part of the section performs the support and drainage functions and, tightly to its lateral sides, has the form of alternating bearing projections (9) and drain gaps (10) between them. Support ledges lie on the surface on which the channel is installed, and said drainage gaps towards the longitudinal axis of the channel converge into the central drainage chute (11), forming a single drainage system.
EFFECT: efficient removal of liquid from above and below the channel, system durability, simple and reliable mounting and dismantling, as well as expansion of the range of similar devices.
