Description

technical field [0001] The invention relates to the technical field of gas pipeline openings, in particular to a construction method for non-stop conveying and pressure openings and a plugging device thereof. Background technique [0002] In recent years, my country's urban gas has rapidly become popular, and the urban gas industry has made great progress in terms of operation scale and application efficiency, which has promoted the reform of my country's energy supply and application forms, and improved people's quality of life. [0003] In the construction of gas pipelines, it is usually necessary to connect branch pipelines with conveyor belt pressure. In the prior art, welding plugging pipes are generally used in the corresponding position of the main pipeline, the plugging valve is opened, and the plugging valve is removed after drilling. In the construction process, the blocking valve needs to be opened and closed frequently, and a large number of construction operatio...
