Description

Technical Field

[0001] This utility model relates to the field of anchor technology, specifically a self-locking anchor for soil nailing wall construction. Background Technology

[0002] Soil nails are steel bars inserted into the soil, commonly used for reinforcing slopes of foundation pits or hillsides. The process is as follows: reinforcement holes are set at numerous predetermined points on the slope of the foundation pit or hillside. Soil nails are placed into these holes, and grouting pipes are inserted into the holes to inject grout. The numerous soil nails are then fixed together on the outside of the slope, forming a support structure. When inserting the soil nails into the reinforcement holes, they must be coaxial with the holes to achieve a good reinforcement effect. The traditional method is to fabricate them on-site, welding steel reinforcement supports to the soil nails for fixation and to center the reinforcement bars.

[0003] In the process of realizing this utility model, the inventors discovered the following unresolved problems in the prior art: existing self-locking anchor rods used in soil nailing wall construction often have multiple sets of threaded mechanisms fixed to the outside of the steel reinforcement brackets to center the anchor rod. However, existing threaded rebar brackets require multiple steel reinforcement brackets to be uniformly sleeved on the end of the anchor rod, and then moved to a suitable array position and fixed with screws. Since the anchor rod is more than ten meters long, this sleeve installation method has unsatisfactory installation efficiency and urgently needs to be improved. Therefore, we propose a self-locking anchor rod for soil nailing wall construction. Utility Model Content
