<p>A drain grate may be provided by the roadside to drain sewage or rainwater. The drain grate may have a frame formed as a hollow parallelogram. The overall width of the hollow parallelogram-shaped frame may have the same overall width as a receiving area of the drain system for receiving the drain grate, thereby preventing the inflow of impurities in the receiving area. The drain grate may have a lever member to easily lift the drain grate. Two frames of the hollow parallelogram-shaped frames are formed inwardly slanted downwards, thereby allowing easy separation of the drain grate from the drain system. A plurality of support bars may be arranged parallel to a water flow direction to smoothly drain sewage and rainwater.</p> |
