大中型供水管路一般采用钢筋混凝土管或铸铁管埋地敷设,管路采用承插式连接,经多年使用后,往往因管基沉陷、按口老化、地面动衍载等原因影响,造成承插口脱落、管路开裂、甚至管路破裂.导致了供水中断,急需维护。常用的处理管路漏水要中断供水,把管路里的水排干再用包箍石棉水泥打口处理,管路断水往往影响生产正常进行,而本文介绍的供水管道带压修补法不需停水作业,对处理所有的管路漏水、跑水都适用。
Large and medium-sized water supply pipelines are usually laid by laying reinforced concrete pipe or cast iron pipe, and the pipelines are socket-connected. After years of use, pipelines often collapse due to pipe foundation, aging of the mouth, Sink off, pipeline cracking, or pipeline rupture, resulting in interruption of water supply, in urgent need of maintenance. Commonly used to deal with pipe leakage to interrupt the water supply, the water pipe to drain and then use asbestos cement package mouth hoop handling, pipeline water often affect the normal production, and this article describes the water supply pipeline pressure repair method does not need to stop Water operations, to deal with all the pipeline leakage, running water are applicable.
