- 摘要:
- W市供水主干管DN2 400顶管出现漏点，漏点位于城市快速路下，埋深约10 m，不具备长时间停水和开挖条件。为避免管道持续渗漏造成道路塌陷等其他次生安全问题，定位、修复漏点等抢修工作刻不容缓。该实际案例采用Sahara Ⅱ检测技术进行漏点分析和定位，漏点修复以及修复过程中采取的应急保障措施等具有参考意义。
- Abstract:
- Leakage point was found in DN2 400 jacking pipe of water main pipe in W city. The leakage point is located under the urban expressway, with a buried depth of 10 m, without long time water cut-off and excavation conditions. In order to avoid other secondary safety problems caused by continuous pipeline leakage, the location and emergency repair work needs to be carried out immediately. The Sahara Ⅱ detection technology was applied in the real case for analysis and location, and the leakage emergency repair as well as safeguard measures could provide reference for others.
