Abstract

The invention discloses an inflatable electric power pipeline sealing device and a production method. The sealing device is characterized by comprising an air type sealing bag body comprising a sealing bag body. The sealing bag body consists of a soft metal surface layer and multiple high-molecular material layers and is in shape of a flat ball body. A cavity is arranged in the sealing bag body. High temperature resisting waterproof films are integrated into the sealing bag body are recombined on two sides of the surface of the sealing bag body. An air charging opening is arranged in one end of the sealing bag body. The interior of the air charging opening contains self-filling colloid materials. A wear-resisting layer is arranged on the soft metal surface layer of the sealing bag body. A waterproof glue layer is coated on the inner wall of the sealing bag body. According to the invention, after air is charged by use of the inflatable electric power pipeline sealing device, cables in a pipeline can be sufficiently protected and sealed, and service lifetime is prolonged.

Description

technical field [0001] The invention relates to the technical field of pipeline sealing equipment, in particular to an inflatable power pipeline sealing equipment and a production method. Background technique [0002] At present, our country uses cement and other materials to block power pipelines for cables that have been buried in the ground. The disadvantage of this method is that the material and the pipeline will lose their waterproof effect due to thermal expansion and contraction and cracking, making it necessary to pump water before construction in the future. In addition, Operations such as cable maintenance will destroy the pipeline seal and need to be resealed; thus a lot of manpower and material resources are wasted. The Chinese invention whose authorized notification number is CN204167851U discloses an inflatable cable duct sealing device, which is characterized in that an inflatable sealing tape is provided, and the inflatable sealing tape is formed into a clos...
