- Title:
- Application of Spiral Winding Method in Trenchless Repair of Super Large Diameter Drainage Pipeline
- 摘要:
- 排水管道非开挖修复技术具有对环境影响小、工作效率高等优势,已被广泛应用于实际工程,但长度超过5 km、管道直径达2 000 mm的非开挖修复案例较少。九江市十里河截污管道管径为DN2 000~2 200,CCTV资料显示该管道缺陷率高,需进行修复。结合管道现状,将机械制螺旋缠绕技术用于十里河超大口径截污管道非开挖修复。修复过程中攻克了大水量超长距离导排难度大、大管径修复工艺不成熟、有限空间作业安全风险大等难题,圆满完成了工程任务,CCTV检测结果显示,修复效果良好。
- Abstract:
- Trenchless repair technology of drainage pipeline has been widely applied in practical engineering due to its advantages of low environmental impact and high work efficiency. However, there are few trenchless repair cases for pipes with length of more than 5 km and diameter of 2 000 mm. The diameter of Shilihe sewage interception pipeline in Jiujiang is between DN2 000 and DN2 200. CCTV data showed that the pipeline had a high defect rate and needed to be repaired. According to the current situation of pipeline, mechanical spiral winding technology was applied for trenchless repair of Shilihe sewage interception pipeline with a super large diameter. In the process of repair, problems such as difficult to discharge large amount of wastewater over long distance, immature repair process of large pipe diameter and high safety risk of limited space operation were overcome, and the engineering task was successfully completed. CCTV test results showed that good repair performance was obtained.
