摘　　要：针对城市老城区雨水管网提标改造需求大,但实施条件受限的实际情况,为了不全面大幅改造整个区域雨水管网,提出了一种基于管道排水负荷的老城区雨水管网改造的设计方法。根据设计排水标准,以管道排水负荷为导向,通过整合区域雨水管网系统,制定不同的管道排水负荷等级,并适当增大局部位置管道布置密度以降低雨水管网系统的管道排水负荷,从而提升整个区域排水能力,同时协调泵闸运行,增大管道水力坡降。以武汉市青山临江片老城区雨水管网改造为例,介绍了基于该法的具体设计方案。实际运行情况表明,该区经历了数场P=1~5 a的降雨,原积水点均未发生积水,达到了预期效果。In view of the urgent demand for upgrading the rainwater pipe network in old urban dis- triet and the limited implementation conditions pipeline drainage load index was put forward in work in the whole area. Based on the design , the method of the design for the reconstruction based on order not to completely reconstruct the rainwater pipe net- drainage standard, guided by the drainage load index, some methods were adopted to achieve the upgrading drainage capability of the rainwater pipe network such as integrating rainwater pipe network of the area, setting up different pipeline drainage load degrees, and reducing the drainage load of rainwater pipe network by appropriately increasing the density of rain- water pipeline layout in the area. Besides, pumps were coordinated to sluices so as to increase the pipe hydraulic gradient. Taking there construction of rainwater pipe network in the old urban district adjacentto the Yangtze River of Qingshan District in Wuhan as an example, the specific design based on this method was introduced, the actual operation results showed that the area experienced several rainfall for 1 -5 years, and no water has been accumulated at the original water accumulation point, which achieved the expected reconstruction performance.
