In the process of opening the lining pipe and recovering the lining pipe to the original diameter by utilizing air pressure or water pressure and the soft ball, sealing plates are generally welded at two ends of the lining pipe in the prior art, the welding sealing plates at two ends of the lining pipe are disassembled after the lining pipe is fully opened, and the lining pipe can be finally attached to the inner wall of the original pipe due to medium pressure in the pipe in the use process after the pipeline is repaired. The technology has the advantages of good sanitary performance, small loss of the flow section, large deformation application range, long-distance restoration and the like, and is widely applied to restoration work of related pipe networks such as water supply and drainage and the like, but the two ends of the liner pipe are sealed by adopting the welding sealing plates, so that the operation is complex and the field implementation is difficult. Meanwhile, the joint can be installed only by firstly carrying out rounding and testing on the good condition after the lining pipe penetrates, so that a sealing device which is convenient to operate on site, economical and applicable is required to be installed, and the operation can be completed quickly.
This patent application has just proposed a pipeline in the non-excavation lining pipe compound circle and has aerifyd clamp type sealing device under this background.
