Through the individual rigidity of the positioning components and the turning property during connection, the end-to-end connected positioning components are clamped and limited by the side wall of the pipeline in the pipeline, so that the overall axis is located on the same horizontal straight line and coaxial with the pipeline, so that the position of the supporting inner module in the pipeline is reversed by the moving distance of the push slide, so that the supporting inner module is in the pipeline. The inner module corresponds to each hydraulic puncher in sequence, and then the hydraulic punchers run in sequence and punch the side wall of the pipe, which can not only keep the punching positions of the pipe accurate, but also timely support the inside of the pipe through the supporting inner module to prevent the side wall of the pipe from being dented after being impacted during punching, thereby adapting to pipes with low wall thickness and overcoming the length limitation of ordinary pipe jacking equipment.
