Emergency repair method for urban water supply and distribution pipeline
The invention discloses an emergency repair method for an urban water supply and distribution pipeline, and belongs to the technical field of water supply and energy conservation. The method comprisesthe steps of cutting off a water source, searching for a water leakage point, maintaining a pipeline and introducing water; the step of maintaining the pipeline comprises the following steps that a hole is formed in the pipeline wall close to the water leakage point of the pipeline, two air bags are guided into the pipeline from the hole in the pipeline wall, and the air bags are located on the two sides of the water leakage point of the pipeline correspondingly; the air bag is inflated rapidly, the air bag expands and is tightly attached to the inner wall of the pipeline, and therefore waterflow in the pipeline is blocked on the two sides of the water leakage point of the pipeline; and water between the air bags is discharged to perform maintenance operation so as to seal the water leakage point of the pipeline. According to the emergency repair method, the pipelines on the two sides of the water leakage point of the pipeline are sealed in an air bag plugging mode, when the pipelineis repaired, water in the pipeline between the water leakage point and upstream and downstream valves does not need to be emptied, so that water resources are saved, meanwhile, the maintenance time is shortened, and the maintenance cost is reduced.
本发明公开了一种城市供水配水管线应急抢修方法，属于供水节能技术领域。一种城市供水配水管线应急抢修方法，包括切断水源步骤、查找漏水点步骤、维修管道步骤及通水步骤。其中，维修管道步骤包括：在管道漏水点附近的管道壁上开孔，从管道壁上的开孔处向管道内部导入两个气囊，气囊分别位于管道漏水点两侧；向气囊中迅速充气，气囊膨胀并紧密贴合在管道内壁上，从而将管道中的水流封堵在管道漏水点两侧；排空气囊之间的水，进行维修操作从而封闭管道漏水点。本发明采用气囊封堵的方式封闭管道漏水点两侧的管道，抢修管道时，不需要排空漏水点与上下游阀门之间的管道内的水，从而节约了水资源，同时缩短了维修时间，降低了维修成本。
