TECHNICAL FIELD

[0001] The utility model relates to the technical field of anchor cable support, and specifically relates to a trajectory guide multi-sliding-block linkage control type anchor cable. BACKGROUND

[0002] Anchor cables are widely used in slope support, with significant effects of enhancing slope stability, reducing deformation and preventing landslides. By transferring loads to deep stable rock mass, anchor cables can effectively control slope sliding, especially suitable for highway, railway and mine engineering, effectively reducing the risk of landslides. In tunnel and underground engineering, anchor cables can strengthen the bearing capacity of surrounding rock, control rock mass deformation and ensure the safety of tunnel construction and operation. Especially in soft surrounding rock and high ground stress areas, anchor cables can effectively reduce the initial support pressure and cooperate with other support measures to significantly improve the stability and durability of the tunnel.

[0003] However, anchor cables still have some problems in actual use. In complex geological conditions, anchor cables in soft rock, fault fracture zone or aquifer are difficult to anchor firmly, which may lead to insufficient anchoring force or failure, thereby increasing the risk of slope sliding or surrounding rock collapse. In addition, anchor cable construction involves drilling, grouting, tensioning and other links, with high technical requirements and construction quality easily affected, often with problems such as drilling deviation and improper tensioning force control, resulting in actual performance lower than design requirements. To solve these problems, the utility model patent proposes a trajectory guide multi-sliding-block linkage control type anchor cable, which adopts trajectory guide and mechanical engagement design to overcome the defects of traditional anchoring systems, while realizing simpler disassembly and assembly operation and significantly reducing the cost of later maintenance and replacement of parts.
