我国多数城市的供水管道普遍存在老旧、破损问题,管网漏损问题严重。结合吉林市水务集团有限公司对所辖全市区约1300km主干供水管网(探测至用户表前)所进行的漏水状况探测工作,对城市给水管道漏水因素进行了科学分析,指出气锤、水锤因素、供水压力因素、施工质量因素、管材材质与质量因素等是造成给水管道漏水故障的主要因素,吉林市这类北方城市的气温变化因素也是造成漏水故障的主要因素之一,并针对这些因素,提出了建立地下供水管线远程无线监控系统,科学开关泵、阀,保持管线工作压力稳定,建立专业的探漏、修漏队伍等应对措施。通过这些行之有效的应对措施可实现预防爆管、降低管网漏损、控制渗漏反弹,从而降低供水企业的产销差,减少管道漏水对城市建筑和人民生活等造成的损害。
The water supply pipelines in most cities in China are generally old and damaged. The leakage problem of the pipeline network is serious. Combined with Jilin City Water Supply Group Co., Ltd., it conducted a leak detection of the main water supply network (detected to the user’s front) of the city’s circumstance of about 1300km, and conducted a scientific analysis of the water leakage factors of the urban water supply pipeline, and pointed out that the air hammer and water hammer Factors, water supply pressure factors, construction quality factors, pipe materials and quality factors are the main factors causing water pipeline leakage failures. The temperature change factors of these northern cities in Jilin City are also one of the major factors causing leakage failures, and these factors are It proposed the establishment of a remote wireless monitoring system for underground water supply pipelines, scientifically switching pumps and valves, keeping the working pressure of pipelines stable, and establishing professional leak detection and repairing teams and other countermeasures. Through these effective countermeasures, prevention of pipe burst, reduction of pipe network leakage, and control of leakage rebound can be realized, thereby reducing the production and sales gap of the water supply companies and reducing the damage caused by pipeline leakage to urban buildings and people’s lives.
