Compared with prior art, the utility model has the beneficial effects that：
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and being implemented in accordance with the contents of the specification, and in order to allow the above and other purpose, feature of the utility model
It can be clearer and more comprehensible with advantage, it is special below to lift preferred embodiment, and coordinate attached drawing, it is described in detail.
Description of the drawings
Fig. 1 is the utility model original state structural schematic diagram.
Fig. 2 is the status architecture schematic diagram after the utility model slip casting.
Each label and corresponding entitled in figure：
1. Grouting Pipe；2. check valve；3. pouch；4. supporting rod；5. protecting pullover.
Specific implementation mode
A kind of bellows device for plugging, as depicted in figs. 1 and 2, including Grouting Pipe 1, pouch 3, check valve 2, supporting rod 4 and guarantor
Sheath head 5.Pouch 3 is expanding bag made of flexible material, and 3 both ends of pouch are equipped with sack, and supporting rod 4 is threaded through in pouch 3,
Pouch 3 is stretched out at the both ends of supporting rod 4, and the lower end of supporting rod 4 is threadedly coupled with pullover 5 is protected, and the upper end of supporting rod 4 passes through unidirectional
Valve 2 is threadedly coupled with Grouting Pipe 1.Two sacks of pouch 3 are protecting the outer wall at pullover 5 and check valve 2 with supporting rod 4 respectively
It is sealedly and fixedly connected, 3 lower end of pouch is amplexiformed with 5 upper end of protection pullover.Supporting rod 4 is internally provided with cavity, and supporting rod 4 is in pouch 3
Internal outer wall is equipped with the injected hole being connected to cavity, and supporting rod 4 is equipped with the note being connected with cavity in one end of check valve 2
Starch mouth.Grouting Pipe 1, check valve 2, grouting port, cavity and injected hole sequentially form slurries and enter the slip casting channel inside pouch 3.
Preferably, it is easy to process, supporting rod 4 uses straight pipe, the lower end of supporting rod 4 to be equipped with external screw thread, protect
