一种检测灌注桩钢筋笼长度的方法——充电法
DETECTING THE REINFORCEMENT CAGE LENGTH IN THE CAST-IN-SITU BORED BY THE 'MISE-A-LA-MASSE' METHOD

摘要: 介绍了利用传统的充电法原理检测灌注桩中钢筋笼长度的方法。理论分析和模型桩试验皆表明钢筋笼的底端对应于电位梯度曲线的极小值点或电位曲线的拐点。某海岸带大型水泥厂桩基工程的应用表明,该方法有效、实用、快速。Abstract: The way to detect the length of the reinforcement cage in the cast-in-situ bored pile by the traditional 'mise-a-la-masse' method is introduced. Results of the theory analysis and the modern pile test indicate that the bottom of the reinforcement cage corresponds to the minimum of the electric potential gradient curve and the inflexion of the electric potential curve. The practice shows that the way is effective, practicable, fast.
