摘要
为了解给水管网爆管发生的规律,借助网络信息平台和搜索引擎,收集并整理了2013年国内网络媒体报道的给水爆管事故190起。通过从时间、位置、原因、管材、使用年限等方面分析,可以看出2013年给水爆管多发生在季节变换月份和严寒月份(尤其是1月);在一天内,5～17时爆管较多;交通主干道及其路口或交叉口、施工工地附近也是爆管的多发地带;重型车碾压、管道老化、野蛮施工和气温变化是爆管的主要原因;媒体报道爆管管径集中在DN200～DN600、DN800和DN1000～DN1200范围内,尤以DN800爆管最严重;管龄在20年以上的,爆管概率较高。此外,在维修上,相关部门抢修及时,近八成的爆管问题都可以在24 h之内解决。
In order to find out rules of pipe bursts, 190 burst events reported by domestic web news in 2013 were collected and analyzed. The statistical analysis results showed that bursts often occurred in the months when seasons change or bitterly cold. 5：00 ~ 17：00 was a dangerous phase for bursts in a whole day. The main roads, the intersections and the construction site were more likely to become the accident locations. Heavy trunks rolling, aging of pipes, barbaric construction and the change of temperature are factors affecting pipe bursts. The diameter of burst pipe was concentrated in DN200 - DN600, DN800 and DN1000 - DN1200. The probability of burst might increase when pipe age in 20 - 40 years. The relevant department dealt with bursts in time, about 80% bursts problems could be solved in 24 hours.
