摘要
大宁水库库区被南水北调北京段输水线路横穿,具备调蓄南水北调来水功能的条件。由于大宁水库地质基本上为砂卵石地层,要增加调蓄水库功能,需要先做防渗,大宁水库的防渗工程采用塑性混凝土修建成墙的型式。施工过程中,通过施工参数、工艺流程、特殊情况处理、质量控制成果等各个方面的严格质量把关,实现了防渗墙工程的优良标准,为大宁水库作为调蓄水库蓄水提供了保障。
As water line of Beijing Section in the South-to-North Water Diversion Project is just across Da＇ning reservoir area, the reservoir has a condition to regulate and store water from the Project. Because the reservoir＇s strata are mostly sandy gravel, seepage prevention was applied to enhance the reservoir＇s function. The anti-leakage type was plastic concrete cut-off wall. In the construction, strict quality checks were carried out in the aspects of construction parameters, technical production flow, special treatment and quality control to ensure the impervious core meets the standard in order to guarantee the Da＇ning Reservoir as a storage reservoir.
