摘要
排海管涵作为城市污水排出的最后一道门槛,只有安全、合理设计才能保证整个排水系统的正常运行,从而避免城市上游出现雨天积水、城市内涝等情况.以厦门市某排海管涵的设计为例,根据汇水面积、径流系数、重现期、管径、坡度、水头损失、过流能力等参数对排海管涵进行计算分析,并结合现场情况进行排海管涵设计.
Abstract
As the last threshold of urban drainage,only safe and reasonable design can ensure the normal operation of the entire drainage system,so as to avoid water accumulation and urban waterlogging in the upper reaches of the city.Taking the design of a sea discharge pipe culvert in Xiamen City as an example,the sea discharge pipe culvert was calculated and analyzed according to the catchment area,runoff coeficient,return period,pipe diameter,slope,head loss,overflow capacity and other parameters,and the design of the sea discharge pipe culvert was carried out according to the site conditions.
