[0017] The beneficial effect of this improvement is that the knotted arrangement prevents the arresting steel cable from falling off the reinforced arresting cable fixing seat.

[0018] In order to limit the position of the steel mesh in the up, down, left and right directions:

[0019] As a further improvement of the above technical solution: the steel mesh is penetrated by expansion anchor bolts and anchor rods.

[0020] The beneficial effect of this improvement is that the expansion anchor bolts and anchor rods are driven into the rock wall after passing through the mesh holes of the steel mesh, without causing damage to the steel mesh, and can limit the position of the steel mesh in the up, down, left and right directions.
