摘要:
我国丘陵地区供水管网普遍存在拐点多、坡度大、漏损率高、开挖修复受限、农田征用困难等问题。柔性复合软管内衬技术作为一种非开挖紧密贴合修复工艺，具有过弯能力强、单次修复距离长、施工快捷、对周边环境与生产生活影响小、综合效益显著等优势，适用于复杂地形老旧管网的更新改造。以湖南省益阳市灰山港丘陵地区DN500输水主管修复工程为例，系统阐述该技术的材料性能、施工流程、质量控制要点与关键技术措施，以及针对深基坑支护、小半径拐点、大高差陡坡、狭小场地反向牵引、短时停水保供等典型难题的解决方案。工程实践表明，修复后管道运行压力由0.15 MPa提升至0.30 MPa，漏损率显著降低，爆管隐患消除，输水能力与供水安全性大幅提升。
Abstract:
Water supply networks in hilly areas of China generally face problems such as numerous bends, steep slopes, high leakage rates, limited excavation repair, and difficulties in farmland expropriation. As a trenchless tight-fit repair technology, flexible composite liner method possesses advantages such as strong bending capability, long single-repair distance, minimal impact on the surrounding environment and daily life, and significant comprehensive benefits, making it suitable for the renewal and renovation of aging pipelines in complex terrains. Taking the repair project of a DN500 water transmission main in the hilly area of Huishan Port, Yiyang City, Hunan Province as an example, this paper systematically expounded on the material construction process, quality control points, and key technical measures. It proposed solutions to typical challenges such as deep foundation pit support, small-radius bends, steep slopes with large differences, reverse pulling in confined spaces, and water supply assurance during short-term water shutdowns. Engineering practice indicated that after repair, the operating pressure of the pipeline increased from 0.15 MPa to 0.30 MPa, the leakage rate was significantly reduced, the risk of pipe bursts was eliminated, and the water transmission capacity and water s safety were greatly improved.
