Clean water and sewage separate two-stage drainage system of bridge
The invention relates to a clean water and sewage separate two-stage drainage system of a bridge. An upper release pipe and a lower release pipe are connected in a sleeved mode, and the lower release pipe is communicated with a longitudinal drainage pipe. A longitudinal slope is arranged on the longitudinal drainage pipe, and the bottom of the longitudinal slope is connected with a sewage treatment system. A tee joint with a water outlet upwards inclined is arranged on the longitudinal drainage pipe, the bottom of the water outlet in the tee joint is higher than the bottom of the longitudinal drainage pipe at the corresponding position, and the height difference is namely a water level limit value. The end of the water outlet in the tee joint, with the water outlet upwards inclined, arranged on the longitudinal drainage pipe is connected with a vertical drainage pipe through a hose. By the adoption of the clean water and sewage separate two-stage drainage system, at the early stage of a heavy rain and when a moderate rain and a light rain occurs or other bridge deck sewage occurs, the water level is lower than the bottom of the water outlet in the tee joint, and accumulated water flows into the sewage treatment system only through the longitudinal drainage pipe. When the water level is higher than the bottom of the water outlet in the tee joint, a part of the accumulated water flows into the sewage treatment system through the longitudinal drainage pipe, and the other part of the accumulated water flows into the vertical drainage pipe through the tee joint to be drained. The clean water and sewage separate two-stage drainage system can drain kinds of bridge deck accumulated water in time and reduce loads of the drainage system, the sewage treatment system and the bridge.
