[0002] Before gas pipeline installation, it is common to use pipe mouth plugging cap such plugging construction equipment. It is generally made of plastic or rubber material, and is made into a cap shape that matches the outer diameter of the gas pipeline. Before pipeline transportation, storage and early construction, it is tightly fitted on both ends of the pipeline. It can effectively block dust and debris from entering the pipeline, prevent dirt from affecting gas delivery or causing blockage, protect the pipe mouth from external damage such as collision, and maintain the integrity and sealing of the interface, laying a solid foundation for subsequent smooth installation and safe use of the gas pipeline.

[0003] In the field of gas pipeline construction, the current plugging products such as pipe mouth plugging cap have a common and difficult problem - easy to fall off. After repeated use of such products, due to frequent contact and friction with the pipeline, the part that was originally tightly attached to the outside of the pipe mouth will gradually wear out, causing the gap between them to increase. Even if the construction personnel try to use a rope to tie and fix it, it is still very easy to fall off in the bumpy transportation or in the complex construction environment, affected by external factors such as vibration and collision, the plugging cap cannot stably play its role of blocking dust and protecting the pipe mouth, causing many inconveniences and potential risks to the gas pipeline construction.
