深灌注桩的质量控制措施

On quality control measures of deep bored piles

以实际工程为例,详细介绍了深灌注桩施工难度大、成孔垂直度控制要求高、超深灌注桩孔壁稳定要求高等特点,着重从施工工艺、质量通病防治等方面对深灌注桩施工所采取的一系列措施进行了阐述,以保证桩身质量取得更好的社会、经济效益。

Taking the factual projects as the example,the paper mainly introduces the construction of the deep bored pile is features with construction difficulties,high requirements for pore-forming verticality control,and higher stability requirements for super-deep bored pile poll walls,and illustrates a set of measures to be adopted in the deep bored pile construction from the construction craft and prevention of quality common diseases,so as to achieve better social and economic benefits of the pile quality.
