| 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。

| Abstract: | 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 ... |
