In-situ calibration self-cleaning pore water pressure gauge
The invention relates to the technical field of pore water pressure gauges, in particular to an in-situ calibration self-cleaning pore water pressure gauge. The invention provides an in-situ calibration self-cleaning pore water pressure gauge. The in-situ calibration self-cleaning pore water pressure gauge comprises a protection pipe, a sensing element, a signal line, a shell, an inner pipe, a barrel, a water injection pipe, a water drainage pipe, a lifting driving mechanism and a rotation driving mechanism. The sensing element is arranged in the protection tube, and one end of the signal line extends into the protection tube and is connected with the sensing element; the shell is cylindrical, a cylindrical cavity is formed in the shell, the bottom end and the top end of the shell are both sealed, the inner pipe is coaxially arranged in the cavity of the shell, and the barrel is coaxially arranged in the inner pipe. According to the pore water pressure gauge, porous stone is replaced by micron-sized graphite, calibration work can be carried out at any time, the sand filter layer and expansive clay do not need to be cleaned, the pore water pressure gauge is taken out and then calibration is carried out, use is simpler and more convenient, and installation complexity is reduced.
本发明涉及孔隙水压力计技术领域，具体涉及一种原位校准自清洗孔隙水压力计。本发明提供的一种原位校准自清洗孔隙水压力计，包括保护管、传感元件、信号线、外壳、内管、筒体、注水管、排水管、升降驱动机构和旋转驱动机构；所述传感元件设于所述保护管的内部，所述信号线的一端伸入所述保护管的内部并与所述传感元件相连；所述外壳呈圆筒状，其内部具有呈圆柱状的空腔，所述外壳的底端以及顶端均呈密封状，所述内管同轴设于所述外壳的空腔内，所述筒体同轴设置于所述内管的内部。本孔隙水压力计使用微米级石墨替代透水石，能随时进行校对工作，无需清理掉砂滤层以及膨胀性粘土取出孔隙水压力计再进行校对，使用更加简单方便，减少了安装的繁琐性。
