Plugging device for construction pipeline without fuel gas transmission interruption

According to the construction pipeline fuel gas non-stop transmission plugging device, the temporary bypass pipe can be quickly spliced and mounted through cooperation of the mounting piece and the temporary bypass pipe, and the efficiency of construction pipeline fuel gas non-stop transmission plugging operation is greatly improved under the condition that the good sealing condition is guaranteed; and the temporary by-pass pipes with different lengths are utilized through the connecting pipe, so that the size requirement of the non-stop conveying plugging operation on the temporary by-pass pipes is reduced, the operation difficulty is further reduced, and the operation efficiency is improved. 本申请提供一种施工管线燃气不停输封堵装置，通过安装件和临时旁通管的配合可以快速对临时旁通管进行拼接安装，保证密封状况良好的情况下，极大地提升了对施工管线燃气的不停输封堵作业的效率；并且通过衔接管利用不同长度的临时旁通管，降低了不停输封堵作业对临时旁通管的尺寸要求，进一步降低了作业难度，提高作业效率。
