针对威海市垃圾处理厂截污坝帷幕渗透系数K≤5.52×10-7cm/s 的较高防渗要求，在截污坝帷幕灌浆工程中采用水泥灌浆结合HS酸性水玻璃材料对基础进行复合灌浆处理，采用这种工艺后的灌浆效果完全满足透水率＜0.044 Lu的设计要求。

Aiming at the high seepage proof requirement that the permeability coefficient K should be equal to or less than 5.52×10-7 cm/s for the curtain of interception pollutant dam belonging to Weihai Refuses Treating Plant, the composed grouting foundation treatment was performed using cement grouting admixing a HS acidic water glass material. The grouting effect has me t the design requirement that the permeability rate is less than 0.044 Lu.
