Cable duct sealing deviceIt is a new pipeline sealing system that absorbs the advantages of similar products both domestically and internationally, and has independent intellectual property rights. This system provides complete waterproof sealing for various pipelines such as plastic, steel, and concrete. The cable duct sealing device can effectively prevent water leakage to the pipe holes on the user side, the basement of the substation, or the receiving room.

　　With the rapid development of China's economy and the gradual improvement of various urban infrastructure，Cable duct sealing device.Higher requirements and standards have been put forward for the construction and maintenance of underground pipelines. Underground communication and power pipelines are generally made of materials such as plastic, fiberglass, cement, etc., buried in pre excavated underground trenches, and artificial wells are set up at a certain distance as work points for pipeline safety management such as wiring, inspection, maintenance, and repair. The sealing device for cable ducts, in general, cement is the main body of the artificial well at the working point. Due to the fact that the pipelines between each well are connected, if the pipelines are not waterproof and sealed or improperly treated, rainwater, sewage, sludge, etc. will be generated.Cable duct sealing device,，Long term infiltration into pipelines, or invasion and reproduction, death, and decay of mice and insects, can lead to cable breakage. At the same time, the workload of pumping and maintenance for pipelines has greatly increased, especially due to the failure of a certain section of cable, which cannot be pumped in a timely manner. Therefore, a convenient and fast method is needed to solve this problem.

　　At present, there are generally several processing methods: Method 1: it is an overall solution for artificial wells,Cable duct sealing device，It is quite expensive and not suitable for promotion; Method 2: Seal the pipeline with materials such as cement, plugging agent, and anti cement. The disadvantage of these methods is that due to thermal expansion and shrinkage cracking, the waterproofing effect between the material and the pipeline will be lost. The cable duct sealing device, in addition, as long as the repair and other operations on the cable will damage the pipeline sealing material, it needs to be resealed, which is not conducive to the expansion of the cable in the future. Due to the pipeline being repaired and blocked, it needs to be repaired, which may damage the entire pipeline; Method 3: Independently developed by domestic companiesCable duct sealing deviceThis problem has been solved very well.
