大直径钻孔灌注桩检测综述

Discussion on Inspection of Large-Diameter Bored Pile

大直径钻孔灌注桩属地下隐蔽工程、施工程序多,容易产生质量事故。对其进行成孔和成桩检测,是十分必要的。对这些检测方法,测试人员并不陌生,但检测过程的一些热点问题及如何互相配合使用,未必有全面的了解,现根据我们多年的实践经验,对其中的相关问题进行分析讨论,以引起大家的重视。

Large-diameter bored pile belongs to concealed engineering. It involves many construction procedures and can causes quality problems easily. Therefore, it is necessary to inspect the quality of the boreholes and the piles. Such inspection methods are not unfamiliar to us. However, there are still some problems to be addressed. Based on the practical experiences of many years, some of the related problems are analyzed and discussed in this paper so that such problems can be paid more attention to during the pile inspection.
