- 摘要:
- 新建道路下穿铁路、立体交叉道路时易成为积滞水点，下凹桥区雨水调蓄排放系统设计的合理性是确保下穿道路安全运行、避免内涝灾害的重要条件。在北京市锅炉厂南路雨水调蓄泵站设计中，结合下凹桥区的特点，在高排水防涝标准和黑臭水体治理的背景下，探讨了其防淹涝措施、雨水收集、狭小且不规则空间下的集约化布置、运行工况等内容，在用地紧张的城市核心区建设了集水泵强排、削减洪峰流量、径流污染控制等多功能于一体的雨水调蓄排放系统。实际汛期运行中状况良好，下凹桥区未出现积水，有效保障了道路运行安全。
- Abstract:
- Newly-built roads are likely to become stagnant water points when they pass through railways and three-dimensional crossing road. Therefore, the reasonable design of stormwater regulation, storage and discharge system in concave bridge area is important to ensure the safe operation of the concave bridge area and avoid waterlogging disaster. In the design of Guoluchangnan Road stormwater regulation and storage pumping station in Beijing, the waterlogging prevention measures, stormwater collection, intensive arrangement in small and irregular space and operation conditions were discussed under the background of strict drainage and flood control standard and black and smelly water body remediation in combination with the characteristics of the concave bridge area. A multi?functional stormwater storage and discharge system was built in a central urban district with tight land use, which integrated the functions such as pump drainage, reduction of flood peak flow and runoff pollution control. The actual operation of the system was in good condition in the flood season, and there was no water accumulation in the concave bridge area, which effectively ensured the safety of road operation.
