Our premium self drilling anchor system is a fully integrated ground support solution, professionally assembled with hollow anchor bars, threaded couplers, high strength nuts, wear resistant drill bits, load bearing anchor plates and centralizers. Engineered for one stop construction, this all in one anchoring system is specially optimized for stabilizing loose soil and fractured rock formations, delivering reliable reinforcement for diverse geotechnical engineering projects.
Versatile and adaptable, our self drilling anchor bolts are perfectly suited for challenging geological terrains, including sand soil, gravel strata, silt, clay, and soft to moderately broken rock masses. Adopting refined industrial design, our self drilling anchoring products streamline on site installation procedures, and we support full customization services to match personalized requirements of different construction projects worldwide.
Breaking through the technical bottlenecks of traditional anchoring techniques, our self drilling anchor system features simplified and mature construction workflows. Equipped with disposable drill bits and hollow through type anchor bars, the system enables seamless drilling in collapsible soil layers and loose surrounding rocks without pre drilling and hole casing procedures. Upon completion of drilling operations, cement slurry or resin grout can be injected continuously through the hollow bar cavity to fill internal and peripheral gaps, greatly boosting overall construction efficiency and anchoring integrity for ground reinforcement projects.
The complete product portfolio covers core accessories including hexagonal locking nuts, heavy duty bearing plates, extension couplers (optional for multi section bar splicing), hollow anchor bodies and disposable drilling bits. All components undergo strict quality control, ensuring integral structural stability and long lasting ground support performance even in harsh and complex underground construction environments.
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.
