In pipeline construction, multiple pipelines usually need to be welded to meet the installation length requirements. Before welding, it is usually necessary to dock the interfaces of the two pipes. In the prior art, two pipes are generally placed on a level ground and then welded after a simple butt joint. However, when the pipeline is placed on the level ground, it is easy to shake, causing the two pipelines to become misaligned, which requires re-butting and welding. This is not only time-consuming and labor-intensive, but also affects the welding efficiency and effect, thereby affecting the efficiency and effect of the pipeline construction.
