Synchronous drainage, grouting and plugging device for confined water of drill hole

According to the drill hole confined water synchronous drainage grouting plugging device, the driving structure drives the contraction fixing mechanism to unfold, the fixing pipe is fixed in the drill hole, at the moment, grouting operation is conducted in the bag through the grouting pipe, the bag expands accordingly, the drill hole is plugged, at the moment, drained water in the drill hole is drained through the fixing pipe, the drainage pipe and the faucet, and the water in the drill hole is drained through the drainage pipe and the faucet. By arranging the telescopic contraction fixing mechanism, fixing of the fixing pipe can be assisted, it is guaranteed that the position of the fixing pipe does not move relatively, the grouting process of the bag is more stable, the contraction fixing mechanism can assist rapid installation of the fixing pipe, plugging operation is greatly facilitated, and the device is good in plugging effect, convenient to construct and high in practicability. And convenience is provi
