8. The blast hole water burst freezing prevention device in the alpine region according to claim 1, wherein the PE waterproof inner film has a cold-proof and seepage-proof function and has a thickness of 0.4-mm-0.8 mm.
9. A method of using the blast hole water burst freezing prevention device in alpine regions as claimed in any one of claims 1 to 8, comprising the steps of:
1) Selecting a PE upper pipeline, a PE pipeline, a separation type base, a PE waterproof inner membrane and a pipeline cover ring according to the diameter and depth of the blast hole;
2) The selected PE upper pipeline, PE pipeline and separated base are respectively connected in a rotary way through a pipe cap, a pipe head and internal and external threads of the pipe, so that the PE upper pipeline, the PE pipeline and the separated base are tightly combined and water-proof;
3) Putting the PE waterproof inner membrane into a PE pipeline combined with the separated base, and inflating the PE waterproof inner membrane by using an air-compressing and water-draining device to enable the PE waterproof inner membrane to be fully contacted with the separated base and the inner wall of the PE pipeline without gaps, and connecting a pipeline cover ring with an upper buckle of the PE pipeline through a groove after the PE waterproof inner membrane is completed, so that the upper part of the PE waterproof inner membrane is fixedly locked;
4) The underground water gushing out of the blast hole is discharged by utilizing the compressed air drainage device, two rope holes are immediately bound by utilizing a rigid rope, the blast hole gushing water freezing prevention device in the alpine region is pulled up to the position above the blast hole by utilizing the traction of a crane, and then the blast hole is slowly placed into the blast hole, so that the bottom of the blast hole reaches the lower part of the charging position of the blast hole, and the underground gushing water is isolated;
5) Charging the gun hole, putting the medicine from the upper end of the pipeline cover ring into the separated base at the bottom of the device;
6) After the charging of the blast hole is finished, firstly, the pipe cover ring is detached, the PE waterproof inner membrane is closed, the steel bars are inserted into the rope holes, the PE upper pipe and the PE pipe rotate anticlockwise, the rope holes are bound by the steel ropes after the whole PE upper pipe and the PE pipe are separated from the separating base, and then the whole blast hole water burst freezing prevention device is lifted by a crane;
7) Taking out the whole device separated from the separated base;
8) And (5) filling the blast hole.
