Description

Technical Field

[0001] The invention belongs to the technical field of water pipe plugging, and in particular relates to a water pipe pressure-based waterproof plugging construction device. Background Art

[0002] Reducing downtime is one of the important meanings of pressure waterproofing and plugging. Traditional water pipe maintenance usually requires stopping work and draining, which not only affects normal production and life, but also causes economic losses. Pressure waterproofing and plugging can be carried out under normal operation of the pipeline.
