At present, there is no detailed and clear detection method and technical standard for large pipe jacking in the existing norms and standards in China. The sealing performance of pipe jacking interface is an important indicator to measure the quality of pipe jacking construction. Therefore, how to seal the pipe butt joint during pipe butt jointing to connect two adjacent pipes and prevent the sealing effect of the pipe joint from becoming a technical problem to be solved in the field.
