摘　　要：由于规划用地内大面积设置雨洪利用设施,在雨洪利用设施设计标准范围内的雨水不允许排放,奥林匹克公园中心区雨水排放系统仅为超雨洪利用标准的道路广场以及休闲花园绿地内人行道等地面径流雨水的排放系统。因此,中心区雨水排放系统的雨量设计参数力求与雨洪利用设计标准配套,雨水收集系统的设计按照溢流排水的原则开发并采用了多项新型雨水的收集设施。中心区内景观道路与市政道路交织,包括多条机动车道,赛时,庆典广场等将会停放新闻采访等重型车辆。因此在管材、喾井的选型及管道开槽、基础、回填等方面采用了市政管线的做法,并采用了相关的市政施工规范及标准。Because of rain and flood utilization facilities, the rain water whose volume is under the capacity of rain and flood utilization facilities is not allowed to discharge. Rain water drainage system in Olympic Common Domain severs only to drain the amount of rain water which is over design capacity of road and square and severs to prevent water flow in greenland of park and field. Therefore, the design parameters of rainfall are trying to be selected to match with rain and flood utilization facilities. The design of rain water collection device in rain and flood utilization facilities observes the principle of drainage of overflow water, and several new rain water collection devices are chosen. Because sight roads have cross-connection with municipal roads, including motor roads and heavy vehicles, such as news and broadcasting vehicles, would park on the ceremony square at match time, the design of piping material, selection of Yinjing, construction of pipe follow the standard design, construction code and regulation of municipal piping.
