Method for detecting stress in pile planting process of prefabricated pipe pile
The invention belongs to the technical field of prefabricated pipe piles, discloses a method for detecting stress in the pile planting process of a prefabricated pipe pile, and provides a method for detecting the stress in the pile planting process of the prefabricated pipe pile in order to solve the problems that the cost of a model experiment is high and a sensor in an in-situ experiment is easy to damage. The strain gauge and the acceleration sensor are installed in a drilling mode in the process of implanting the prefabricated pipe pile, and data collected by the strain gauge and the acceleration sensor are transmitted to the foundation pile dynamic tester and the computer, so that the stress distribution condition is obtained. The device integrates the functions of hammer pile penetration depth control, signal collection, data processing, curve output and the like, reliability and practicability are both considered, the continuity of the experiment process is ensured, and numerical simulation verification can be combined in the later period.
本发明属于预制管桩技术领域，公开了一种预制管桩植桩过程应力检测方法，为了解决模型实验成本高、原位实验中的传感器容易损坏的问题，而提供一种预制管桩植桩过程应力检测方法。本发明通过在预制管桩植入的过程中通过钻孔的方式安装应变片和加速度传感器，并将应变片和加速度传感器采集的数据传输给基桩动测仪和电脑从而获得应力分布情况。本发明集锤桩入土深度控制、信号收集、数据处理、曲线输出等功能于一体，兼顾可靠性和实用性，确保了实验过程的连续性，后期还可结合数值模拟验证。
