大直径混凝土供水管道漏水修复技术

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。

Leakage Fixing Techniques for Large-diameter Concrete Water Supply Pipes

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 adopted and grouting is implemented behind. Measures are also taken to improve the fixing work, which ensures a fast construction speed, a good construction quality and a low cost. Thus, good economic and social benefits are obtained.
