Embodiment Construction
[0014] combine figure 1 and figure 2 , the present invention is further described:
[0015] A hydrological observation device capable of passing through a frozen wall, comprising a plurality of hydrological holes 20 opened along the length direction of the inclined shaft 10, the vertical ground of the hydrological holes 20 is opened and extended to the middle non-frozen region 31 of the frozen wall 30, The hydrological hole 20 is connected with a pressure detection tube 40, and the pressure detection tube 40 is located in the middle non-moving junction area 31 of the freezing wall 30. A permeable hole 41 is opened on the tube body, and the pressure detection tube 40 is pressed into the detection oil , The pressure detection tube 40 is provided with a pressure detection device for detecting the internal pressure.
[0016] combine figure 1 As shown, since the depth of the inclined well construction is generally not deep, the cost of the detection device is relatively low. Du...
