| description | The invention relates to a rivet pulling and pressing type locking structure of a pre-stressed anchor rod and an anchoring construction method. The pre-stressed anchor rod is provided with a first clamping structure; the sleeve structure is provided with a first matching section and a deformation section, the first clamping structure is arranged in the first matching section and the deformation section in a penetrating manner, and the first clamping structure is clamped with the first matching section; after the pre-stressed anchor rod enters an anchoring hole of a rock mass and forms first anchoring force with the rock mass, pulling force is applied to the pre-stressed anchor rod through the tensioning mechanism, the first clamping structure is driven to drive the first matching section to extrude the deformation section, the deformation section abuts against the hole wall, and second anchoring force is formed. Due to the arrangement, tight combination between the pre-stressed anchor rod and the sleeve struc |
