Hammering positioning frame based on high strain method detection
The invention relates to a hammering positioning frame technology, aims to solve the problem of low accuracy of detected data caused by influence of gravity center shift of an impact hammer and mounting position shift of a sensor on data detected by a high-strain method, and particularly relates to a hammering positioning frame based on high-strain method detection, which comprises a bottom frame, an upper frame is mounted at the upper end of the bottom frame, and a lower frame is mounted at the lower end of the upper frame. An impact pile is arranged in the middle of the inner side of the bottom frame; sliding adjustment of the transverse distance and the vertical distance is carried out through the telescopic assemblies on the transverse frame and the vertical frame, so that the center of the bottom frame coincides with the center of the impact pile, position deviation is avoided when the impact hammer hammers the impact pile, the accuracy of detected detection data is improved, and the detection efficiency is improved. The two spiral drill bits can conduct drilling operation on the surface of the impact pile, a drilled hole cannot deviate, the stress direction of the sensor can be kept parallel to the axis of the impact pile, and the accuracy of data detected by the sensor can be improved conveniently.
本发明涉及锤击定位架技术，用于解决高应变法检测数据受冲击锤重心偏移和传感器安装位置偏移影响，导致检测到的数据准确性较低的问题，具体为一种基于高应变法检测的锤击定位架，包括底框架，所述底框架上端安装有上框架，所述底框架内侧中间位置处设有冲击桩；本发明通过横向框架和竖向框架上的伸缩组件进行横向距离和竖向距离的滑动调节，使底框架的中心与冲击桩的中心重合，使冲击锤对冲击桩进行锤击时不会发生位置的偏移，使检测到的检测数据准确性得到提高，通过使两个螺旋钻头可在冲击桩的表面进行钻孔操作，钻出的孔洞不会发生偏移的情况，使传感器的受力方向可与冲击桩的轴线保持平行的状态，便于提高传感器检测数据的准确性。
