摘要
近年来,极端天气频发,城市内涝频繁出现,为防止周边地面雨水等汇入倒灌地下道路造成损失,城市地下道路的排水驼峰设置越来越受瞩目。本文合地下道路建设经验,分析排水驼峰的设计要点,总结设置排水驼峰后与周边衔接细节,同时若因纵断面布置限制,驼峰高程难以达到要求时,提出地下通道排水应考虑的其他措施,以便最大限度的发挥地下道路的功能。
In recent years,the extreme weather takes place frequently and the urban waterlogging occurs frequently.In order to prevent the surrounding ground rainwater into the underground roads to cause a loss,the settings of drainage hump for the urban underground roads are getting more and more attention.Combined with the construction experience of underground road,the design essentials of drainage hump are analyzed,and the details to connect the surroundings after the settings of drainage hump are summarized.At the same time,if the layout of vertical section is limited,and the elevation of hump is hard to meet the requirements,the other measures should be considered for the drainage of underground roads in order to maximize the function of the underground roads.
