An environment-friendly drainage structure of a road is provided to extend the service life by reducing the velocity of rainwater and wastewater flowing in a drainage, purifying rainwater or wastewater and preventing the subsidence of a drain pipe. The environment-friendly drainage structure of a road comprises a drain pipe(10) formed to have a U-shaped cross-section and provided with upper and lower subsidence prevention projections to prevent the drain pipe from subsiding to the lower part by external impact, a guide plate(20) fixed to inner wings of the drain pipe to slow down the drainage speed of rainwater or wastewater and to filter out waste of the upper part if a portion of rainwater or wastewater flowing along the drain pipe flows inward, a filter net(30) fixed to the top of the drain pipe to prevent the inflow of impurities, a vegetation plate(40) planting water purifying plants in a vegetation unit to absorb nutritive substance from the rainwater or wastewater, thereby to improve natural purification capability for rainwater or wastewater, a connector(50) connecting many drain pipes in the longitudinal direction, and a weight cover(60) fastening and fixing the connector and the drain pipe. |
