The disc-shaped airbag 3 penetrates the vent pipe 2 and is arranged on a side close to the baffle 1, and the disc-shaped airbag 3 is connected to the vent pipe 2. At least two rod-shaped airbags 4 are fixedly connected to the outside of the vent pipe 2 in an annular array, and the rod-shaped airbags 4 are located in the reserved hole, and the rod-shaped airbags 4 are perpendicular to the vent pipe 2 after being inflated, and the end of the inflated rod-shaped airbag 4 away from the vent pipe 2 abuts against the inner wall of the reserved hole. The remaining space inside the reserved hole is filled with cement mortar 12, and the cement mortar 12 is poured from the hole on one side away from the baffle 1.

[0028] The baffle 1 is circular in structure and has a diameter larger than the diameter of the reserved hole, and the end of the vent pipe 2 is connected to the middle of the baffle 1. Specifically, the baffle 1 can be threadedly connected to the vent pipe 2 so as to be sleeved on the outside of the end of the vent pipe 2, and the end of the vent pipe 2 can also be directly welded to the middle of the baffle 1.
