大直径混凝土供水管道漏水修复技术

摘要

In the Angat water supply project in Philippine, serious leakage problems are found in the concrete pipes of AQ5 water supply line, which is of a large diameter of 3.6 m.To fix the leakage, 6 mm thick steel lining pipe is adopt-ed and grouting is implemented behind.Measures are also taken to improve the fixing work, which ensures a fast con-struction speed, a good construction quality and a low cost.Thus, good economic and social benefits are obtained.%为解决菲律宾安嘎特供水工程AQ5号供水管线3．6 m直径混凝土管道严重漏水问题，采用壁厚6 mm薄钢衬管、壁后充填灌浆修复技术，通过实验，采取了一系列措施，改进了施工工艺，达到了施工速度快、工程质量优、修复成本低的目的，取得了较好的经济效益和社会效益。
