Concrete pile foundation detection method
The invention relates to a concrete pile foundation detection method, and belongs to the field of building engineering detection. According to the method, leveling treatment is carried out on the piletop of a to-be-detected pile foundation, multiple measurement sensors used for measuring the to-be-detected pile foundation are mounted at the pile top of the to-be-detected pile foundation, the timetravel curve of the accelerated speed response of the pile top is measured through a low-energy transient shock excitation manner, it is ensured that steady shock excitation can obtain a stable response signal under each set frequency, the shock excitation force of steady shock excitation is adjusted according to the conditions of the pile diameter, the pile length and the constraint of soil around the pile, the average wave speed of the pile body is detected, whether the defects of pile breaking and cracks exist in the pile body or not is judged, vertical compressive property detection is carried out on the to-be-detected pile foundation, and vertical anti-pull detection is carried out on the single pile foundation. By means of the method, integrity of the pile foundation can be detected, and the compressive property and the anti-pull property of the to-be-detected pile foundation can be detected.
本发明涉及一种混凝土桩基检测方法，建筑工程检测领域。它对待测桩基的桩顶进行平整处理，将多个用于测量待测桩基的测量传感器安装于待测桩基的桩顶，通过低能量瞬态激振的方式实测桩顶的加速度响应的时程曲线，确保稳态激振在每一个设定的频率下均能获得稳定的响应信号，并根据桩径、桩长及桩周土约束情况调整稳态激振的的激振力大小，检测桩身的平均波速，判断桩身是否存在断桩和裂缝缺陷，对待测桩基进行竖向抗压性能检测，对单体桩基进行竖向抗拔检测。本发明不仅能够检测桩基的完整性，而且还能检测待测桩基的抗压性能和抗拔性能。
