摘要
从清孔不彻底、灌注过程中坍孔和缩颈、导管进水及埋深不合理、初灌量选择不当、混凝土质量不好等方面分析了产生断桩的原因,并提出了相应的预防措施和处理方法,以保证钻孔灌注桩的成桩质量。
From incomplete pile hole cleaning, hole collapse, necking, improper embedded depth and first pouring amount, quality questions of concrete and other aspects reasons caused the breakage of cast-in-place bored pile are analyzed; at the same time corresponding prevention and treatment measures are proposed in order to ensure the engineering quality of pile.
