摘要
针对阿海水电站坝基岩石细微裂隙透水性强而可灌性却相对较差的特点,为提高其可灌性,采用80μm细度筛筛余量1.2%的低细度525R普通硅酸盐水泥作为灌浆材料。为确保灌浆帷幕的防渗效果及可靠性,使用灌浆自动记录仪记录灌浆参数,保证了灌浆资料的真实性,对指导灌浆工作的顺利进行起到了重要作用。
In light of Ahai reservoir characteristics of strong permeating and weak irrigation of dam foundation rock small crack, in order to improving the irrigation, it applies 80 μm fine screen 525R common aluminum silicate with 1. 2% rest amount as the grouting material, In order to guarantee the anti-seepage effect and reliability of the grouting curtain, it uses automatic grouting recorder to record grouting parameter. Thus, it guarantees the reality of the grouting material, which has significant role for guide smooth operation of grouting work.
