Device and method for detecting penetration of hammered pile

The invention discloses a device and a method for detecting the penetration of a hammered pile, and relates to the field of engineering machinery. The detection device comprises a high-speed motion camera, a penetration detection control terminal and reflective stripes used for being attached to a pile body. The high-speed motion camera is connected with the terminal and controlled by the terminal, and transmits collected data to the terminal at the same time. And the terminal obtains the penetration through data processing and displays the penetration in real time. A non-contact remote detection method is adopted, manual detection errors can be avoided, the problem that a displacement sensor is inconvenient to install is solved, and the piling efficiency can be improved. 本发明公开了锤击桩的贯入度检测装置及检测方法，涉及工程机械领域。该检测装置包括高速运动相机和贯入度检测控制终端，以及用于贴于桩身上的反光条纹。所述高速运动相机与终端相连并受终端控制，同时将采集的数据传递给终端。终端通过数据处理得到贯入度并实时显示。本发明采用无接触的远程检测方法，能够避免人为检测误差，解决位移传感器安装不便的问题，可以提高打桩的效率。
