关州水电站防渗墙泥浆净化回收利用实践

Practice of Mud Purification and Recycling in Cut-off Wall Construction for Guanzhou Hydropower Station

摘要:

关州水电站位于较为偏僻的丹巴县境内，工程所在地没有合格的粘土，只能使用外运的膨润土作为防渗墙固壁泥浆的原料，工程成本很高。冲击钻机施工防渗墙的泥浆净化回收利用存在较大的难度。因此进行了冲击钻机施工防渗墙的泥浆净化回收利用技术的研究，应用效果良好，显著节约了泥浆成本。

Abstract:

Guanzhou hydropower station is located in remote Danba County, because there is no qualified clay, which has to be replaced by bentonite with high project cost. As it is very difficult for mud purification and recycling in cut-off wall construction by use of percussion drill, the study is specially made and good effects are achieved with mud cost saving.
