Description

Technical Field

[0001] This invention belongs to the field of steep slope repair technology in subsidence areas, and more specifically, relates to an anchoring device for steep slope repair in subsidence areas. Background Technology

[0002] Subsidence area steep slope restoration is a systematic governance process that combines engineering and ecological measures to address problems such as surface subsidence and slope instability caused by mining and other activities. Its core objective is to eliminate potential geological hazards, restore ecological functions, and achieve sustainable use of land resources. Anchoring devices are required during subsidence area steep slope restoration.

[0003] The current anchoring devices have the following problems: 1. They usually do not have auxiliary reinforcement functions, which affects the stability of the connection, and the screws or nuts are prone to loosening after being tightened; 2. When the anchor rod is connected to the external rope, the stress point is located on the anchor rod, and it cannot provide auxiliary support for the stress; 3. They cannot protect the bottom of the anchor rod, which makes it easy for workers to be injured by the bottom of the anchor rod, and they cannot improve the installation speed of the anchor rod. Summary of the Invention

The triangular support frame provides auxiliary force support, increasing the stability of the circular hollow rod after installation. Workers can use a hammer to assist in installing the circular hollow rod, improving the installation speed. This solves the problems of typically lacking auxiliary reinforcement functions, being unable to provide auxiliary support, and failing to increase the installation speed of anchor bolts.
