Foundation pile rock-socketed depth detection method based on one-transmitting double-receiving transducer
The invention provides a foundation pile rock-socketed depth detection method based on a one-transmitting double-receiving transducer. The method comprises the following steps: S1, selecting a plurality of detection points in a detection hole of a foundation pile; s2, detecting a plurality of detection points in the detection hole by using a one-transmitting double-receiving transducer, wherein each detection point is subjected to single detection to obtain two groups of sound wave data; s3, calculating a correlation coefficient of the two groups of sound wave data of each detection point; s4, drawing by taking the depth of the detection hole as a vertical coordinate and taking the value of the correlation coefficient as a horizontal coordinate; and S5, the position of the rock-socketed surface is judged, wherein the depth value corresponding to the point with the minimum correlation coefficient in the curve is the depth of the rock-socketed surface, and the rock-socketed depth is obtained by subtracting the depth of the rock-socketed surface from the length of the foundation pile. Important reference indexes are provided for building foundation pile pulling resistance evaluation, the detection method is simple and easy to operate, the detection cost is low, the whole oscillogram is analyzed, the analysis range is wide, and the result is accurate.
本发明提供了一种基于一发双收换能器的基桩嵌岩深度检测方法，包括如下步骤：S1：在基桩的探测孔内选取多个检测点；S2：利用一发双收换能器对探测孔内多个检测点进行探测，每个探测点单次检测获得两组声波数据；S3：计算每个探测点的两组声波数据的相关系数；S4：以探测孔的深度为纵坐标、相关系数的值为横坐标作图；S5：判断嵌岩面位置：曲线中相关系数最小的点对应的深度值即为嵌岩面的深度，所述嵌岩深度为基桩的长度减去嵌岩面的深度。本发明为建筑基桩抗拔力评价提供重要参考指标，检测方法简单易操作，检测成本低，对整个波形图进行了分析，分析范围广、结果精确。
