Static sounding probe combined with TDR (time domain reflectometry) technology, detection system and measurement method
The invention relates to a static sounding probe combined with a TDR (time domain reflectometry) technology, a detection system and a measurement method.The probe comprises a conical head, a probe rod, a probe control unit, a TDR probe, a first detection mechanism used for detecting conical tip resistance, a second detection mechanism used for detecting side friction resistance and a third detection mechanism used for detecting pore water pressure, the conical head comprises a conical section and a cylindrical section, the number of the TDR probes is multiple, the outer side wall of the conical head is provided with clamping grooves which are consistent with the number of the TDR probes, the clamping grooves are arranged around the surface of the conical head at equal angles, the TDR probes are embedded in the clamping grooves respectively, the directions of the TDR probes are parallel to the axial direction of the conical head, the contact surfaces of the TDR probes and the conical head are provided with insulating layers, and the end parts of the TDR probes are conical. The TDR probe extends to the conical section of the conical head and is in smooth transition with the conical surface of the conical section, and the TDR probe and the detection mechanisms are all connected with the probe control unit. Compared with the prior art, the device has the advantages that the measurement accuracy is improved, and a plurality of parameters of the soil body can be continuously measured.
本发明涉及一种结合TDR技术的静力触探探头、检测系统和测量方法,其中探头包括锥头、探杆和探头控制单元,以及TDR探针、用于检测锥尖阻力的第一检测机构、用于检测侧摩阻力的第二检测机构、用于检测孔隙水压力的第三检测机构,锥头包括圆锥段和圆柱段,TDR探针共设有多个,锥头的外侧壁上设有与TDR探针数量一致的卡槽,各卡槽环绕锥头表面等角度布置,各TDR探针分别嵌于各卡槽中,且TDR探针的方向与锥头轴向平行,TDR探针与锥头的接触面上设有绝缘层,TDR探针的端部成锥形,延伸至锥头的圆锥段处,并与圆锥段的锥面平滑过渡,TDR探针、和各检测机构均与探头控制单元连接。与现有技术相比,本发明具有提高测量准确性且能能够连续测量土体多个参数等优点。
