摘要
雨水口是城镇雨水排放系统的收集装置,如数量不足、位置布置不当易造成路面积水。为进一步精细化设计,避免设计重现期标准状态下路面积水,改善市民出行体验,减少安全隐患,在参考相关规范进行理论计算分析的基础上,结合实际工程设计需要,提出以横向水面宽度为控制指标,定量计算确定雨水口布置间距,以截流率为主要指标之一,定量计算确定雨水口布置数量(长度)的设计计算思路和方法,以减少凭经验取值的盲目性。
Rainwater inlet is the collection device of town rainwater discharge system.The pavement waterlogging is easy to cause if its quantity is not sufficient and its location is improper.In order to further refine the design,to avoid the pavement waterlogging under the design recurrence interval standard state,to improve the travel experience of citizens,to reduce the safety risks,on the basis of theoretical calculation analysis referring to the related standards and combined with the practical engineering design demand,this paper puts forward the transverse water surface width as the control index,quantitatively calculates and determines the layout distance of rainwater inlet.And taking the intercepting rate as one of the main indexes,this paper quantitatively calculates and determines the design calculation idea and method of layout quantity and length of rainwater inlet in order to reduce the blindness of empirical value.
