钻孔灌注桩成孔垂直度检测与控制

Verticality Detecting and Controlling of Pore-forming of Bored Pile

介绍了2种常用的钻孔灌注桩成孔垂直度检测方法,检查器法多用于施工单位内部自检测,而超声波法是一种较为精确的检测手段。文章对成孔垂直度的事前控制措施和事中控制措施进行了探讨,旨在强调钻孔灌注桩垂直度的过程控制,对预防钻孔灌注桩的孔斜现象具有工程实践意义。

Two common methods of pore-forming verticality detection have been introduced. The trial cages inspection is usually used in the self detection of construction companies, and the inspection of ultrasonic is one of the accurate detection methods. Due to emphasizes the control in the pore-forming process, this paper discussed the beforehand and middle control measures for pore- forming verticality, which reflect the significance of preventing the hole deviation.
