Static pressure type pore water pressure testing device and testing method
The invention discloses a static pressure type pore water pressure testing device. The device comprises a static penetrometer, a static sounding probe rod and a pore water pressure gauge device, wherein the static sounding probe rod is arranged on the static penetrometer, and the lower end of the static sounding probe rod is connected with the pore water pressure gauge device; and the pore water pressure gauge device comprises a pore water pressure gauge, a static sounding probe rod connecting sleeve, a penetration protecting pipe and dry sand, wherein the static sounding probe rod connectingsleeve and the penetration protecting pipe movably sleeve the pore water pressure gauge in an up-down arrangement mode, the static probing probe rod connecting sleeve, the penetration protecting pipeand the pore water pressure gauge can move relative to the axial direction, the upper end of the static sounding probe rod connecting sleeve is connected with the static sounding probe rod, and the penetration protecting pipe is filled with the dry sand which can be extruded upwards to cover the surface of a pore water pressure gauge body. The invention further provides a pore water pressure testing method implemented by adopting the device. According to the device and the method, slurry generated during drilling and burying is avoided, and the environment is sanitary; and the device is simplein structure, convenient to operate, high in testing precision, time-saving and labor-saving, and economical and environment-friendly.
一种静压式的孔隙水压力测试装置，包括静力触探仪、静探探杆、孔隙水压力计装置，静力触探仪上安装静探探杆，静探探杆的下端与孔隙水压力计装置连接；孔隙水压力计装置包括孔隙水压力计、静探探杆连接套管、贯入护管、干砂，静探探杆连接套管和贯入护管呈上下布置地活套在孔隙水压力计外且三者可相对轴向移动，静探探杆连接套管的上端与静探探杆连接，贯入护管内填充有可被向上挤出覆盖在孔隙水压力计本体表面的干砂。还提出一种采用该装置实施的孔隙水压力测试方法。本发明避免了钻孔埋设时产生的泥浆，环境卫生，装置结构简单，操作便捷，测试精度高，省时省力，既经济又环保。
