Abstract

The invention provides a single-hole device for measuring underground water flow velocity and flow direction. The device comprises an external support, a seepage tracking unit, a position detection unit, a reset unit and a controller; a connection cylinder is provided with a water passing window; the seepage tracking unit comprises an upper thimble, a lower thimble, a rotating shaft and a seepage tracking rod, wherein the upper thimble, the rotating shaft and the lower thimble are installed coaxially in the vertical direction sequentially; the rotating shaft is fixed by the upper thimble and the lower thimble in a tight pressing mode; the other end of the upper thimble and the other end of the lower thimble are respectively installed in a control room and an under-chassis; the seepage tracking rod is fixed in the horizontal direction in the rotating shaft and two ends of the seepage tracking rod are protruding from the rotating shaft; one end of the seepage tracking rod is provided with an expansion part which is smaller than the water passing window in size; the position detection unit comprises a color code disc and a color recognition module; the reset unit is constituted of more than three electromagnets which are electronically connected to the controller. The device has functions of flow velocity and flow direction tracking, position detecting and resting; by use of the device, non-contact measurement, repeated measurement and continuous measurement can be realized.

Description

technical field [0001] The invention relates to a device for measuring groundwater flow velocity and direction, and belongs to the technical field of geological engineering groundwater measurement. Background technique [0002] A large amount of geological engineering experience shows that the instability and deformation of landslide rock and soil are closely related to groundwater seepage caused by changes in the hydrological environment such as rainfall activities, reservoir water level rise and fall, and industrial wastewater discharge. In order to accurately evaluate the correspondence between groundwater seepage activities and landslide disasters, and monitor the change of groundwater seepage velocity and flow direction in the vertical area between the sliding surface and the slope surface in the landslide mass, it is necessary to accurately grasp the groundwater activities through precise instruments. [0003] At present, there are many methods for measuring the flow r...
