摘要:
某市A污水收集系统d1 800 mm污水主管发生管道脱落事故。脱节管道从检查井洞口滑落至井室内，导致地面土体塌陷。事故发生后，通过压密注浆加固土体、反向顶进钢管以及内衬修复的方法，在最短的时间内恢复了污水主管的输水功能，取得了良好的工程效果，避免了事故险情的扩大。该工程采取的措施为大管径污水主管日常维护及应急抢修积累了经验。
Abstract:
A d1 800 mm sewage main pipe of A sewage collection system fell off in a city. The disjointed pipe slipped from the inspection well opening to the well chamber, causing the ground soil to collapse. After the accident, the water conveyance function of the sewage main pipeline was restored in the shortest time by means of soil compaction grouting reinforcement, reverse jacking steel pipe and lining repair, which achieved good engineering results and avoided the expansion of the accident. The measures taken in this project have accumulated experience for daily maintenance and emergency repair of large diameter sewage main pipelines.
