METHOD OF CONSTRUCTING A DRAINAGE STRUCTURE Russian patent published in 2019 - IPC E01F5/00 

FIELD: construction.

SUBSTANCE: invention relates to road construction and can be used in construction of drainage structures on motor roads. Method of water drainage structure arrangement consists in that channel-tray is made of rectangular shape from prefabricated units in form of separate sections with shortened length and light-weight ones connected to the mouth, their connections are also implemented by means of screw-nut, side upper ends of walls of which have through holes. Channels-trays from prefabricated units are laid according to a pre-arranged slope of road slope. End of last section of collecting channel-tray is installed in recess-stop made in bottom of site-tooth. Conditions are created for flow jet, which from channel-tray first comes to tooth site, expands towards stream-directing vertical walls towards water cushion, then all flow enters into water cushion. Water cushion is made from the high-strength half-located along the longitudinal axis of the asbestos-cement or polyethylene pipe with a shield. Sight of semi-hinged pipe is located above water level to form discharge of water flow from slope of road with further removal through platform tooth into water cushion.

EFFECT: increasing in reliability and durability of nut.
