Sinorock 's anchoring systems are widely used in recent years.
The ductility and shear bond are obviously better than ever.
Besides Williams and Titan, ARCO supplies another self-drilling anchor with super high strength.
Its R32 termic self drilling rods provide over 1100 Mpa tensile strength and over 900 Mpa yield stress.
That means contractors can use smaller anchors to achieve the design value. Cost is saved a lot.
When Atlas sold self drilling anchors business to Minova (now belongs to Orica) in 2011, the next king in the iron throne had changed to DSI. Baratheon in the construction and underground industry.
Now, the market of self-drilling anchor is increasing. Each company has its own influence region.
Eastern Power is unpredictable: here Sinorock has the advantages of low cost, and technics are in progress.
Sinorock self-drilling anchor hollow bars have good ductility and high strength.
The story of self-drilling anchor is far away to be ended.
The drilling and reinforcing in soil and rock won't stop.
Who can be the next anchoring king?
Sinorock SDA hollow-bars overcome these limitations and make the installation faster and more efficient with their one-step process. The bar is drilled into the ground and cement grout is injected through the hollow rod in one operation. During drilling, the grout stabilizes the borehole to prevent it collapsing. Once installed to the required length and after full hardening, the grout transfers the load from the bar into the surrounding soil. The simultaneous grouting ensures full and uniform coverage of grout along the full length of micropile. Extension couplings provides lengthening of the micropiles and the bearing capacity of the connection remains the same as of the bars.
Comparatively small-scale drilling equipment can be used to install the SDA bars as micropiles in tight spaces or with limited headroom. With little vibration or noise, the drilling process itself causes minimal stress on the surrounding structures.
In diverse ground conditions, from gravel, sand, or clay, or on sites with insufficient structural integrity, the Sinorock SDA self-drilling bars as micropiles are versatile in their application, quick and reliable in their installation, and compatible with conventional drilling equipment. Once installed, they are an effective means of preventing settlement and helping to increase soil stability.
