摘要
Based on the project characteristics,and the technical advantages,design conditions,construction control,quality inspection etc of "long spiral rotary jet mixing pile water-stop curtain",this paper introduces in detailed this technology effective sealing effect on the sand and gravel water-bearing layers.As one of the successful examples,this new technology could be generalized and improved.In this case,it would work better in sealing effect on Beijing sandy gravel water-bearing layers,reduce the shallow groundwater discharge,and protect the shallow groundwater resources.
