摘要
为保证工程质量 ,以太钢三钢立式连铸改造出坯跨延长厂房钢筋混凝土钻孔灌注桩施工为例 ,对钻孔灌注桩施工常出现的质量事故 (如坍孔、钢筋笼放不到正确位置、桩身砼质量不合格等 )进行总结 ,对其发生原因进行认真分析 ,并总结出有效的预防措施 。
In order to ensure engineering quality, taking construction of reinforcing concrete drilling pouring pile of ejection crossing extension plant remoulded by vertical casting as a example in the third construction company, Taiyuan steel Co. Ltd, the paper summarizes common quality accidents in drilling pouring pile construction (for example, collapse hole, bar cage isn't put to correct position, unqualified concrete quality of pile body), analyses seriously its producing reasons, and summarizes effective preventive measures. These achieve better effect.
