摘要
钻孔灌注桩的水下混凝土灌注是成桩的关键环节,但由于施工工艺不当,断桩、堵管、夹泥、蜂窝、少灌等质量问题也时有发生。因此,运用科学、实用的混凝土灌注工艺以保证钻孔灌注桩的施工工程质量显得极为重要。
Bored - pile concrete pouring under water is key tache of drilling work.There are often quality problems of breaking pile,blocking up,mud- larding,beehive during engineering because of incorrectly construction technique.It is important to use scientific and applicable concrete pouring technique to ensure the construction quality of bored - pile.
