Foundation pile high strain detection method
The invention discloses a foundation pile high strain detection method. The foundation pile high strain detection method comprises the following steps that (1), a pile head is treated, specifically, when a diesel hammer for construction is used for follow-up driving, an enough depth is reserved for mounting a sensor, when a free hammer is used for testing, a site is cleaned to ensure the use and transition space of a hammering system; (2), the pile side is polished, then punching is carried out, and expansion bolts are mounted; (3), a guide device is mounted, and a hammer pad is arranged; (4), the sensor is mounted at the start reserved selection position, and the free drop hammer is placed at the designated position; and (5), instrument parameters and states are determined, hammering and penetration measurement are carried out, and signal confirmation is carried out to complete measurement. The foundation pile high strain detection method is few in detection steps and high in efficiency, the detection efficiency can be greatly improved, and the detection precision can be remarkably improved by adopting the steps for detection.
本发明公开了一种基桩高应变检测方法，包括以下步骤：1)桩头处理：使用施工用柴油锤跟打时，留出足够深度以备传感器安装；使用自由锤测试时，清理场地确保锤击系统的使用及转场空间；2)对桩侧打磨，然后打孔并安装膨胀螺栓；3)安装导向装置，布置锤垫；4)将传感器安装在开始预留选择位置，并将自由落锤放置在指定位置；5)确定好仪器参数及状态，进行锤击、贯入度测量，并信号确认，完成测量。本发明提供的基桩高应变检测方法检测步骤少、效率高，能够大幅提高检测效率，且采用上述步骤进行检测能够显著提高检测精度。
