Runoff emission reduction device for river-crossing bridge floor
The invention provides a runoff emission reduction device for a river-crossing bridge floor. Auxiliary drain holes are communicated with an overflow pipe and are vertical to the horizontal direction of the longitudinal layout of the road on the outer edge of the deck; main drainage holes are vertically distributed and are communicated with a longitudinal drainage pipe below the bridge floor; the bottom surface elevation of the auxiliary drainage holes is equal to the bridge deck pavement edge, the center elevation of the auxiliary drainage holes is higher than the top surface elevation of themain drainage holes, and meanwhile the auxiliary drainage holes are located at the positions 5-10 cm away from the downstream of the adjacent main drainage holes in the bridge deck runoff direction; aplane of the plug is fixedly connected with one surface of the three-edged rod and is positioned at one third of the length of the three-edged rod; the plug is inserted and positioned in the main drain hole, and one end of the three-edged rod is inserted into the auxiliary drain hole; the overflow pipe is directly guided into a river, and the diameter of the overflow pipe meets the requirement that the plug is fully embedded in the transverse axial direction; and the diameter of the auxiliary drain hole is one third of that of the main drain hole. The method can reduce the discharge pressureof the pipeline.
本发明专利提供一种跨江河桥面的径流减排装置。副排水孔连通溢流管，垂直于道路纵向布局在桥面外侧边缘的水平向；主排水孔竖直向布设且连通桥面下的纵向排水管；副排水孔底面高程与桥面铺装边缘等同，并且副排水孔中心高程高出主排水孔顶面高程，同时在桥面径流方向上副排水孔位于邻近的主排水孔下游五至十公分处；塞子有平面与三棱杆的一个面固结且位于三棱杆的三分之一长度处，塞子插入定位在主排水孔内并且三棱杆一个端头插入副排水孔内；溢流管直接导入江河，且直径满足塞子在横轴向足尺地嵌固；副排水孔直径为主排水孔的三分之一。该方法可减轻管道的排放压力。
