[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figures 1-4The utility model provides a kind of technical scheme: a kind of pipeline temporary plugging structure, including back type rubber capsule pipe 1, pipeline 9, back type rubber capsule pipe 1 inner wall is fixedly connected with rubber seal 2, rubber seal 2 is fixedly connected with drain valve 201, back type rubber capsule pipe 1 both ends are fixedly connected with connecting sheet 3, connecting sheet 3 is embedded and is equipped with wear-resistant collar 301, wear-resistant collar 301 is provided with connecting rope 4 inside.

[0020] In the embodiment, by winding back type rubber capsule pipe 1 at the leakage point of pipeline 9, two connecting sheets 3 are connected together by connecting rope 4 passing through two wear-resistant collars 301, and then back type rubber capsule pipe 1 is wound on pipeline 9, and subsequently, gas is filled into back type rubber capsule pipe 1, back type rubber capsule pipe 1 expands and increases in size, and then the outer wall of back type rubber capsule pipe 1 is attached to the surface of pipeline 9, since back type rubber capsule pipe 1 is connected to pipeline 9 first, the volume of back type rubber capsule pipe 1 increases after expansion, and the gap between back type rubber capsule pipe 1 and pipeline 9 is blocked, and back type rubber capsule pipe 1 is in the shape of a loop, the gap in the inner wall is blocked by rubber seal 2, so that the position in the middle of back type rubber capsule pipe 1 is in a sealed state, and then pipeline 9 is temporarily blocked at the crack, to avoid further permeating clean water to the outside, rubber seal 2 is fixedly connected with drain valve 201, drain valve 201 is in communication with the inside of rubber seal 2, and when the amount of permeated clean water is too large, drain valve 201 can be driven, at this time, the permeated clean water can continue to be discharged from drain valve 201, to play a certain role of drainage and pressure relief, to avoid the problem that back type rubber capsule pipe 1 is difficult to install in place due to too much permeated clean water under the condition of pipeline pressure, and after the installation of back type rubber capsule pipe 1 is completed, closing drain valve 201 can avoid further permeation of clean water.
