为了解给水管网爆管发生的规律和趋势,通过及时把握相关市政给水管道爆管事件报道,借助互联网信息平台和搜索引擎,收集整理了2014年国内给水管网爆管事故,共165起。根据数据显示,冬季(一月)和夏季(六月)是高发季度;一天中5时到17时爆管事故较多;交通主干道及其路口、道路交叉口是爆管的主要地段。从爆管原因方面分析,其中管网老化是市政给水爆管的最主要因素,靠近管道施工、重物碾压、土层变动和气温变化也是导致管道爆裂的重要因素。
In order to understand the regularity and trend of water pipe burst, through timely grasp of the reports of municipal water pipe burst events, with the help of Internet information platform and search engine, we collected 165 cases of domestic pipe burst accidents in 2014. According to the data, winter (January) and summer (June) are the high season; in the first 5 to 17 o’clock, there are more squib accidents; traffic trunk roads and their intersections and road intersections are the main sections of squibs. From the analysis of the reason of pipe burst, the aging of pipe network is the most important factor of municipal water pipe burst. The construction of pipelines, the rolling of heavy objects, the change of soil layer and the change of air temperature are also the important factors leading to pipe burst.
