Movable pore water pressure testing instrument
The invention discloses a movable pore water pressure testing instrument. A testing instrument body is included and is surrounded and wrapped by an expandable outer ring. An inner cavity is formed inthe expandable outer ring. The testing instrument body is provided with an inserting pipe with an inner hole which is straight through up and down. The expandable outer ring is connected with a pressure filling and emptying device through a long guide pipe. The testing instrument body is connected with a data collecting and analyzing device through a long wire. After the expandable outer ring is expanded, and the expandable outer ring can be in tight fit with the inner wall of the inserting pipe to achieve liquid seal. The invention further provides a method for testing pore water pressure through the movable pore water pressure testing instrument. The movable pore water pressure testing instrument can move in a pipeline in the depth direction, the pore water pressure at the depth positioncan be positioned and measured, and the manner for obtaining pore water pressure values of different depths through the movable pore water pressure testing instrument is more simple and convenient.
本发明公开了一种活动式孔隙水压力测试仪，包括测试仪主体，所述测试仪主体环绕包裹有可膨胀外圈，可膨胀外圈内带有内腔，所述测试仪主体配置有带内孔的插管，内孔上下直通，所述可膨胀外圈通过长导管与充压和放空装置连接，所述测试仪主体通过长导线与数据采集和分析装置连接，所述可膨胀外圈膨胀后可与插管内壁紧配并液密封。本发明还提供了采用上述活动式孔隙水压力测试仪进行的孔隙水压力测试方法，该活动式孔隙水压力测试仪可以在管道内沿深度方向移动，并可定位测量该深度位置的孔隙水压力，其获取不同深度孔隙水压力值的方式更加简便。
