Pre-applied force anchoring system for slope protection device and construction method thereof

The invention discloses a pre-applied force anchoring system for a slope protection device and a construction method thereof. The pre-applied force anchoring system comprises a threaded rod (1), concrete bamboo joint blocks (2), connection discs (3), a spring (4) and a nut (5). The concrete bamboo joint blocks (2), the connection discs (3) and the threaded rod (1) form an integrated anchoring body (6), and the concrete bamboo joint blocks (2) and the connection discs (3) are arranged at intervals. The anchoring body (6) is placed into an anchor hole (7), and the gap between the anchoring body (6) and the anchor hole (7) is filled with concrete mortar. The nut (5) is screwed on the threaded rod (1) in a matched mode. The nut (5) tightly presses the slope protection structure and the concrete bamboo joint blocks (2) through the spring (4). The construction method is characterized in that all the concrete bamboo joint blocks (2), all the connection discs (3) and the threaded rod (1) form the integrated anchoring
