ROAD DRAINAGE FACILITY AND CONSTRUCTION METHODS ACCORDINGLY

摘要

The present invention relates to a road drainage facility and a construction method according to the same. The road drainage facility comprises: an inclined drain path (10) formed on an extension line of a shoulder (2) of a road and connected to an inclined surface (12) of piled soil to form an inclination angle to firstly drain rainwater; and an inclined side gutter (20) which is constructed on a road body layer (1a) or an upper road layer (1b) of the inclined surface (12) of the piled soil in a longitudinal direction of the road, and collects the rainwater drained along the inclined drain path. Accordingly, a dyke is omitted by the inclined drain path extended and paved on the inclined surface of the piles soil on the shoulder of the road to quickly drain the rainwater by firstly draining the rainwater when it rains to prevent a hydroplaning phenomenon. The inclined surface of the piles soil becomes weed-proofed by the inclined drain path to eliminate weed removal work to reduce road maintenance and repair time and costs and prevent fatal worker accidents which increase every year. Specifically, the inclined side gutter is positioned on the inclined surface of the piles soil to allow construction of the side gutter using equipment and facilitate dredging work.
