摘　　要：论述了预埋灌浆管法不仅避免了从混凝土面上钻孔,对混凝土内各类预埋件不存在损坏,而且进一步缩短了陡坡基础边坡固灌的施工工期;并从固结灌浆布孔、灌浆管预埋、盖重及灌浆参数合理选定、灌浆成果分析等方面进行了详细的阐述,从而确立满足质量、工期、安全及环保要求的施工方法和工艺。The pre-embeded grouting pipe method is illustrated in this paper and this method is without the need to drill holes on concrete surface,can avoid the pre-embeded part＇s damage and shorten the construction time for the rapid ascent substructure＇s grouting.The consolidation grounting hole＇s arrangement,the grouting pipe＇s pre-embeding,the cover weight and grouting parameter celection and grouting result analysis are described in detail and the construction method and process whichcan satisfy the requirement in guality,time,asfety and environment protection are established too.
