为了在不改变排水管网路径和不加大排水管网规模的同时优化雨水排水系统的性能,提升排水系统能力,在排水管网路径中设置雨水调蓄设施.通过梳理、比对雨水调蓄在实际工程中对雨水排水系统的优化应用,并通过列表对比在不同城市中雨水调蓄在现行的暴雨强度计算公式中对优化排水系统的改善作用.结果表明:分散地在排水路径上设置雨水调蓄设施可以降低排水管网设计的暴雨强度,其效果等同于延长雨水排水管网设计中的降雨历时.因此在建筑小区雨水排水管网设计时采用分散地在排水路径上设置雨水调蓄设施是优化系统的有效措施.该做法既可降低建筑小区排水管网规模又可提高市政雨水排水的安全.
In order to optimize the performance of the rainwater drainage system and improve the drainage system capability without changing the size of the drainage network and without increasing the size of the drainage network, a rainwater storage facility is provided in the drainage network path. In the actual project, the optimization and application of stormwater drainage system is made, and the improvement of drainage system in the current rainstorm intensity calculation formula is compared with the list of rainwater storage in different cities.The results show that: Storage facilities can reduce stormwater intensity of the drainage network design, the effect is equivalent to prolong the rainfall duration of the rainwater drainage network design.Therefore, in the design of the stormwater drainage network in the construction district, scattered rainwater storage facilities Is an effective measure to optimize the system.This approach can not only reduce the size of the drainage pipe network in construction area but also improve the safety of municipal drainage.
