Screw holes 13 are opened on the outer walls of both sides of the jacking pipe body 1. The second bolt 7 is screwed and installed inside the through hole 12 and the screw hole 13. Both sides of the jacking pipe body 1 are installed inside the arc groove 11. The interior of the inner cavity 9 is poured with concrete slurry. The second bolt 7 is arranged inside the inner cavity 9 and the concrete slurry. By installing the second bolt 7 inside the through hole 12 and the screw hole 13, it is convenient to fix the limit head 10 and the jacking pipe body 1, and improve the stability between the limit head 10 and the jacking pipe body 1.
