Referring to fig. 2, the top support portion 11 has a long shape, and one end thereof is fixedly connected to the stabilizing portion 12. The top support 11 has a communication passage 111 along its longitudinal direction, and the communication passage 111 penetrates the stabilizing section 12. When the stabilizing portion 12 supports the pipe blocking balloon, the air intake pipe of the pipe blocking balloon is inserted into the communication passage 111.

Referring to fig. 2, the top support 11 has a horn shape, and one end having a smaller diameter is fixedly connected to an end of the top support 11. The end of the propping part 11 far away from the propping part 11 is provided with a containing groove 121 for placing a pipeline plugging air bag. The space in the accommodation groove 121 is hemispherical in shape to increase the contact area between the jacking portion 11 and the pipe blocking balloon, and to promote the stability of the pipe blocking balloon in the jacking portion 11.

Referring to fig. 2, the bottom of the receiving groove 121 communicates with the communication passage 111 to facilitate the communication of the pipe blocking balloon with its air intake pipe.

The implementation principle of the propping structure of the pipeline plugging air bag of the embodiment is as follows: an uninflated pipe blocking balloon is placed in the accommodation groove 121, and an air intake pipe of the pipe blocking balloon penetrates from the communication passage 111. At the downstream water outlet of the pipeline water leakage point, a pipeline plugging air bag is pushed into the pipeline with water leakage by using a jacking structure 1. When the pipeline plugging air bag reaches a proper position, air is filled into the pipeline plugging air bag by utilizing the air inlet pipe, so that the pipeline plugging air bag is expanded, and the pipeline is plugged.
