The surface of the adjusting support frame 2 is provided with a blocking plate 4, which is driven to move by the adjusting support frame 2. More specifically, the two sets of outer support plates 5 are fixed on the surface of the pipeline body 1 by the bolts 7. The blocking plate 4 is moved along the surface of the adjusting support frame 2 by the adjusting support frame 2, so that the blocking plate 4 is tightly attached to the inner wall of the pipeline body 1. The inner wall of the pipeline body 1 at the pipeline gap 11 on the surface of the pipeline body 1 is blocked by the blocking plate 4. The support seat 3 and the blocking plate 4 provide support force to the inner wall of the pipeline body 1.
