摘要
竹银水库地处珠江三角洲,针对工程施工中深淤泥基坑开挖及支护、深基坑防渗处理、长雨季条件下施工、上坝土料含水率调整、质量检测等方面存在的技术难点,分别采取了薄层置换开挖、块石挤淤加固边坡、坝面帷幕灌浆基础处理、长雨季条件下土坝快速填筑、压实质量快速检测等技术应对措施,实现了工程连续快速施工,12个月内完成坝体填筑,施工质量优良。
The Zhuyin Reservoir is located in the Pearl River Delta. With regard to the technical ditticulties in excavatwn and support of the foundation pit with deep and thick mud, anti-seepage treatment of a deep foundation pit, construction long rainy season, adjustment of water content of dam materials, as well as quality testing and control during its construction, some countermeasures such as excavation by replacing the thin unqualified layer with backfilling materials, stabilization of the slope by squeezing silt with riprap, foundation treatment at the dam site, rapid filling of an earth dam over the long rainy season, and quick quality tests have been adopted. The project achieves continuous and quick construction, and the filling work for the dam was completed within 12 months. The construction quality is satisfactory.
