摘要
针对我国西北干旱地区城市降雨量稀少、雨水管网设施利用率低的情况,提出采用不完全分流制的雨水系统规划方案。并以新疆乌昌新区五一新镇为例,对干旱地区城市不完全分流制雨水系统规划的方法和要点进行阐述。通过建立该地区的雨水排水ICM模型,对该区开发前后雨水径流路径及积水情况进行分析,在此基础上合理规划雨水行泄通道,减少开发后城区易积水点。模拟结果表明,采用不完全分流制利用雨水行泄通道排水是可行的。
Aiming at the situations of little rainfall and low utilization rate of rainwater pipeline network in the cities in the arid northwest of China, this paper puts forward the planning scheme of incompletely separated-system rainwater system. Taking Wuyi New Town in Wuchang New District of Xinjiang as an example, this paper sets forth the methods and essentials of the incompletely separated-system rainwater system planning in the arid cities. Through the establishment of the rainwater drainage ICM mode in this city,this paper analyzes the rainwater runoff route and waterlogging situation of this area before and after developed.On this basis, the rainwater drains are reasonably planned and the waterlogging points easily happening in the urban area after developed are decreased. The simulation result shows that it is feasible to use the incompletely separated-system rainwater drains for drainage.
