摘要
高架道路排水设计的主要目的是收集和排放路面雨雪水。虽然排水设计有规范可遵循,但不同地区、不同气候特征下应有的区别,规范中没有详细的条文说明。乌鲁木齐市近年来完成了外环路、南湖东西路、克拉玛依路等高架道路建设项目,采用了不同的雨水收集和排水方式。现以乌鲁木齐市高架道路排水系统为研究对象,收集了一些工程实例,分析了雨水收集和排水的多种方式,通过对比上海市的雨水量计算结果,结合规范中的相关规定,提出适合乌鲁木齐地区的高架道路雨水收集口型式、间距及排水方式。
The main purpose of drainage design of elevated road is to collect and discharge the snow rainwater of pavement. There are standards for the drainage design to follow, but there are no detailed provisions in the distinguishing standards in the different areas and the different climate features. In recentyear, the elevated road projects of Outer Ring Road, Nanhu Road(E and W), Kalamayi Road and etc. have been completed in Urumqi City with the different rainwater collection and drainage modes. Taking the drainage system of elevated roads in Urumqi as the study object, the article collects some engineering cases,and analyzes many modes of rainwater collection and drainage. According to the comparison of rainwater flow calculation result of Shanghai and according to the relative specifications of the standards, the article proposes the rainwater inlet type and gap, and drainage mode of elevated road in Urumqi Area.
