Two tie nuts 13 are screwed onto the tie bolt 12, and the two tie nuts 13 are respectively located on the outside of the long side of the two L-shaped clamping arms 11, so that the two L-shaped clamping arms 11 are clamped onto the vertical steel or arch frame inside the tunnel.
[0026] The clamping assembly 1 also includes a long strip-shaped connecting rod 14. One end of the connecting rod 14 is welded into the short side of one of the L-shaped clamping arms 11, and the other end of the connecting rod 14 is inserted into the short side of another L-shaped clamping arm 11. A first hexagonal nut 15 is welded to the outside of the short side of the L-shaped clamping arm 11 that receives the connecting rod 14. A second through hole 112 communicating with the first hexagonal nut 15 is opened on the outside of the short side of the L-shaped clamping arm 11 that receives the connecting rod 14. A first wing bolt 16 is screwed into the first hexagonal nut 15. The tail end of the first wing bolt 16 passes through the second through hole 112 and abuts against the connecting rod 14.
[0027] Locking assembly 2 is installed on both sides of clamping assembly 1, and locking assembly 2 fixes clamping assembly 1 to vertical steel or arch frame. Specifically, locking assembly 2 includes second hexagonal nuts 21 and second wing bolts 22. Two second hexagonal nuts 21 are welded to the outer side of the long side of each L-shaped clamping arm 11.

A second wing bolt 22 is screwed into each second hexagonal nut 21. The tail end of the second wing bolt 22 passes through the adjacent third through hole 113 and abuts against the vertical steel or arch frame in the tunnel.
[0028] By using the clamping and locking components together, the anchor pipe can be firmly fixed to the vertical steel or arch frame inside the tunnel, effectively preventing the anchor pipe from loosening and falling off, and improving the stability and safety of the support structure.
