| 摘 要： | 本文以加德满都市旧供水井修复项目为例,针对因滤水管缝隙被化学物质堵塞,导致井出水量逐年减少的旧供水井。通过井下电视摄像系统检查,采用六偏磷酸钠、氨基黄酸等有机酸,结合刷洗、高压喷射等机械方法进行处理,使旧供水井出水量得到明显提高。

| Abstract: | Yielding of the old water-supply wells in Katmandu decreases from year to year due to the screens of the wells are clogged by chemical substances.By checking with the television pickup system,treating with organic acids such as sodium polymetaphosphate and sulfamic acid,and mechanic methods such as washing,high-pressure spraying,the yielding of the old water-supply wells increases considerably. |
