Double-end water plugging device for observing working face overlying strata water flowing fractured zone
The invention discloses a double-end water plugging device for observing a working face overlying strata water flowing fissure zone, which comprises a first elastic plugging body, a second elastic plugging body and an auxiliary moving device, and the auxiliary moving device is used for realizing rolling contact between the elastic plugging bodies and the hole wall of a drill hole; when the elastic plug bodies are pushed to a designated observation position in the drill hole, the rolling contact state between the elastic plug bodies and the hole wall of the drill hole can be relieved by filling pressure water with preset pressure into the elastic plug bodies, so that the elastic plug bodies expand and deform to abut against the inner wall of the drill hole in a sealed mode, and a closed space is formed between the two elastic plug bodies; according to the water plugging device, the auxiliary moving devices are arranged on the two elastic plugging bodies, so that the smoothness of the water plugging device moving in the drill hole can be improved, and the water pressure change of the overlying strata water flowing fracture of the working face can be observed. And the plugging effect of the observation position in the drill hole and the accuracy of the observation result are ensured.
本发明公开了用于工作面覆岩导水裂隙带观测的双端堵水器，包括第一弹性堵体、第二弹性堵体以及辅助移动装置，辅助移动装置用于实现弹性堵体与钻孔孔壁间的滚动接触；当弹性堵体在钻孔内推送至指定观测位置时，通过向弹性堵体充入具有预定压力的压力水，可解除弹性堵体与钻孔孔壁间的滚动接触状态，使弹性堵体膨胀形变以与钻孔内壁密封抵触，迫使两个弹性堵体间形成封闭空间，再单独向封闭空间内充入具有预定压力的压力水，以观测工作面覆岩导水裂隙的水压变化，本发明通过在两个弹性堵体上设置的辅助移动装置，可提高堵水器在钻孔内移动的平顺性，确保对钻孔内观测位置的封堵效果及观测结果的准确性。
