福建大剧院大直径超长钻孔灌注桩的实践

Practice of large diameter and super long drilling hole sprinkling pile in Fujian Theater

以福建大剧院为例,介绍了本工程在抗震要求高、桩承载力高、地质条件复杂等情况下采用大直径超长钻孔灌注桩施工的情况,并从桩位控制、孔径控制、钢筋笼控制等方面提出了保证其质量的措施,以供类似工程参考借鉴。

Taking the example of Fujian Theater, it introduces the situation of adopting large diameter and super long drilling hole sprinkling pile under the condition of high requirement in anti-quaking, high capacity and complex geological condition. It also brings forward measures of ensuring its quality from aspects including control of pile position, hole diameter and steel steamer, so as to offer reference for familiar project.
