Foundation pile breakage and pile length detection method
The invention relates to a foundation pile breakage and pile length detection method. The method comprises the steps that (1), heat transfer pipe holes are formed in a boundary of a foundation pile atspecific intervals, and heat transfer pipes are arranged in the heat transfer pipe holes; (2), measuring holes and comparison holes are formed around the heat transfer pipe holes; (3), temperature probes are uniformly arranged in the measuring holes and the comparison holes; (4), heating is conducted through the heat transfer pipes, and temperature probe data of different depths in the measuringholes and the comparison holes are obtained; (5), differences between temperatures in the measuring holes and temperatures in the comparison holes at the same depth are calculated, and a temperature difference-depth map is drawn by taking the temperature differences as abscissas and depths of the temperature probes as ordinates; and (6), according to positions of abrupt change points in the temperature difference-depth map, the depth of the rightmost abrupt change point is determined to be a pile length of the foundation pile, and the positions of the rest abrupt change points are determined to be pile breakage positions of the foundation pile.
一种基桩断桩以及桩长检测方法，包括：（1）在与基桩边界特定间隔设置传热管孔，传热管孔中设置传热管；（2）在传热管孔周围设置测量孔以及对比孔；（3）在测量孔以及对比孔中设置均匀设置温度探头；（4）通过传热管进行加热，获取测量孔以及对比孔中不同深度的温度探头数据；（5）计算同一深度测量孔中的温度与对比孔中的温度的差值，以温度差值为横坐标，温度探头深度为纵坐标绘制温度差值‑深度图；（6）根据温度差值‑深度图中的突变点的位置，确定最右侧突变点的深度为基桩桩长，其余突变点的位置为基桩断桩位置。
