The invention relates to the field of drainage systems, and more particularly to metal drainage gutters covered by gratings that permit the passage of water, used for collecting and draining water from bridgeworks, roads, etc. The technical result involves increasing the collection and removal of moisture as a result of improving the waterproof properties, anchoring and throughput capacity of the device. The linear drainage channel consists of at least one section, each of which contains a base. A U-shaped gutter contains a base and side walls. Each side wall is designed with a stepped profile, which has two vertical portions and a horizontal shelf disposed therebetween. Beneath the shelves, on the base of the gutter, shaped tubes are accommodated, the outer side face of each of which is perforated. Furthermore, the base has free, longitudinal side portions which are designed with a bend at an angle upwards due to the requirement that the base of the channel can be embedded relative to an installation surface, with subsequent placement of a waterproofing layer thereon. On the underside, the base is provided with embedded elements (tongues) which are disposed at the sides, along the base, spaced at intervals of 100 to 2000 mm, and which can be attached to a reinforcing cage or mounted onto a supporting form. |
