摘要
宁波大工业供水工程的给水主管(DN2 200)破裂,造成大量漏水。采取旁通临时应急供水管道、破裂处两端设置管身挡板及气囊封堵、布置临时围堰、适当降低河道水位、破裂处切割预制修复同步实施的抢修方法,在最短的时间内恢复供水,避免了下游企业陷入停产窘境,为大口径管道的日常维护保养及抢修积累了经验。
The break of a water supply main pipeline （ DN2 200） of Ningbo industrial water supply project caused substantial water leakage. Some technical measures were taken, including using a tem- porary emergency water supply pipeline, installing baffle plates and air bag at both sides of the break, constructing a temporary cofferdam, appropriately lowering river level and simultaneous cutting, prefabri- cation and repair. The water supply was recovered in the short time, the stop production of downstream enterprises was avoided, and the experience was accumulated for routine maintenance and repair of large diameter pipeline.
