High Strength Corrosion Resistant Wear Resistant Self Drilling Anchor System For Ground Support

Manufactured with high strength alloy materials, our anchor couplers serve as reliable extension connectors for self drilling anchor bars. They are compact and space saving, ideal for narrow and confined construction sites, enabling the design and implementation of super long anchor reinforcement for surrounding rock stabilization. Meanwhile, the precision threaded fit effectively minimizes slurry leakage during synchronous drilling and grouting operations, ensuring consistent grouting quality.

We provide two mainstream specifications: hexagonal nuts and spherical surface nuts. These locking components function to fasten bearing plates, transferring the tensile and compressive load of anchor bars evenly to the bearing plates and finally dispersing the stress to the working surface. Featuring equal strength matching design with anchor bar bodies, the nuts fully comply with the ultimate tensile and compressive strength of the anchors, guaranteeing stable load bearing performance of the entire support system.

Fitted with high hardness alloy cutting heads, our custom drill bits deliver exceptional penetration performance. Driven by professional rock drilling equipment, they can efficiently drill through various soil and rock formations. Cooperating with the continuous full thread design of anchor bars, the bits achieve one time rapid hole forming, avoiding hole collapse and re drilling issues in loose and broken strata.

Matched with anchor nuts for tight locking, the heavy duty anchor plates undertake and disperse the overall load of the self drilling anchor system. They effectively transfer structural stress to the construction working face, preventing local stress concentration and improving the overall firmness and durability of ground support structures.

In deep hole drilling projects requiring multi section anchor bar splicing via couplers, anchor bodies are prone to swing and deviation, which affects drilling and grouting accuracy. Our rigid steel centralizers are installed at the front of connecting couplers to restrict excessive displacement and swinging of anchor bars. This precise centering effect ensures straight drilling holes and uniform grout coverage, significantly improving the overall construction quality of deep anchoring projects.
