Excitation detection method for defects of constructional engineering supervision pile foundation
The invention relates to an excitation detection method for defects of a constructional engineering supervision pile foundation. The excitation detection method comprises the steps of drilling a detection hole in a soil layer on the side surface of the pile foundation, arranging a detection guide pipe in the detection hole, arranging an excitation source on the top or on the side wall of the top of the pile foundation, extending a detector into the positions of different depths in the detection guide pipe so as to detect excitation waves emitted by the excitation source, and drawing a time-depth oscillogram according to signals of the detector; and determining the defects of the pile foundation according to the time-depth oscillogram, wherein misjudgment in pile foundation defect detectionis avoided through the arrangement of the excitation detection hole.
一种建筑工程监理桩基缺陷激振检测方法，在桩基侧面土层钻孔设置检测孔，在检测孔中设置检测导管，在桩基顶部或者顶部侧壁设置激振源，将检波器伸入检测导管中不同深度的位置，检测激振源发出激振波，通过检波器的信号绘制时间‑深度波形图；根据时间‑深度波形图确定桩基缺陷，其中通过激振检测孔的设置，避免了桩基缺陷检测中的误判。
