Pile foundation integrity detection method based on thermal response
The invention provides a pile foundation integrity detection method based on thermal response, and belongs to the field of pile foundation detection. The detection method comprises the steps of detection preparation, parameter setting, detection of M positions and data analysis and processing, specifically, sensors are placed in N pre-embedded temperature measuring pipes, then detection of the multiple positions is carried out in the axial direction according to setting, and a time-temperature curve of each temperature measuring pipe at each position is generated; and the obtained time-temperature curve is analyzed and processed, a final abnormal curve is obtained, and the position where the pile foundation defect occurs is determined according to the corresponding temperature measuring tube serial number and the position serial number. According to the method, the defect position of the detected pile foundation is determined by comparing the heat conduction efficiency of different positions of the detected pile foundation with the standard heat conduction efficiency of the test pile according to the difference between the heat conduction coefficients of the pile body material and the defect position of the pile body, the accuracy is high, the method is simple and visual, the pile foundation is not damaged, and nondestructive detection is achieved.
本发明提供了一种基于热响应的桩基完整性检测方法，属于桩基检测领域。所述检测方法包括检测准备、参数设定、M个位置的检测和数据分析和处理，具体的，在预埋N根测温管中放入传感器，然后按照设定沿轴向进行多个位置的检测，并生成出每个测温管在每个位置的时间‑温度曲线；对得到的时间‑温度曲线进行分析和处理，得到最终异常曲线，其对应的测温管序号和位置序号确认桩基缺陷发生的位置。本发明利用桩身材料与桩身缺陷位置热传导系数的差异，通过对比被检测桩基不同位置的热传导效率与试验桩的标准热传导效率确定被检测桩基缺陷位置，精确度高，且简单直观，并对桩基不造成损害，属于无损检测。
