Sinorock hollow bar anchors 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.

In recent years, the self drilling hollow anchor bolts play a more and more important role in the foundation support projects. The unconsolidated ground condition favors it for fast and simple method of installation compared to the traditional method. When it comes to the application of Sinorock? self drilling hollow bar in tunneling, the construction of tunnel and its broken and water surrounding rock has always been one of the important factors that affect the tunnel construction safety and schedule. To replace the advanced small pipe with self drilling anchor bar is one of the ways to ensure the safety of tunnel construction and schedule. 

Today Sinorock is working in every major underground mining around the worldwide and we are very proud to be able to say that the Sinorock is the number-one self drilling hollow anchor bolt scaler in China, even though we are competing with the largest and most well-known brands in the mining market. 

 

Sinorock self drilling hollow bar has historically been known as a “self-drilling anchoring”

Sinorock self drilling hollow bar has historically been known as a “self-drilling anchoring” because the hollow fully-threaded bar serves as both the drill string and the grouted anchor, thus installation is performed in a single operation. 

Sinorock carry a comprehensive range of various self drilling hollow bars,generally speaking, we have two categories as below:

1,R25N, R32L, R32N, R32S, R38N,R51N, T76N, T76S, T111N, T111S

2,T30/16,T30/14,T40/16,T40/20,T52/26,T73/53,T73/45,T73/35,T103/78,T103/51

All self drilling hollow anchor bar can be manufactured in different lengths, like 2 meters, 3 meters, 4 meters, 6 meters or 9 meters. Both left hand thread and right hand thread are available upon customers request.

Besides, we also supply a complete range of accessories, including coupling sleeves, steel plates, nuts, centralizers, and various anchor bits.

Today, after these years, by enjoying a considerable expertise in hollow bar industry, we are honored with our history of importing andintroducing some kinds of self drilling hollow bars in various ranges of capacities to the demanding construction market in our country,together with consulting projects for the purpose of addressing the best location and the optimum choice of capacity, plus extensive sales and after-sales services, providing timely spare parts support, all in accordance with engineering standards worldwide.

Self drilling hollow anchor at home and abroad is moving to the effect of improving anchoring force

At Sinorock, we are an experienced distributor of many types of self drilling hollow anchor bolt and other important products. With an expansive range covering over a dozen product categories, we have made ourselves into a convenient, single-point source for these important products.

The function of a self drilling hollow anchor is to provide anchorage of a structure to a solid substrate - either through active pre-tensioning of the ground anchor to the anchorage zone, or through passive anchorage via low lock–off loads (e.g. rock bolts). The main components of a ground anchor are the bonded length, free length and the anchorage. 

Nowadays, self drilling hollow anchor at home and abroad is moving to the effect of improving anchoring force, efficiency of support and expanding application range. It is believed that developing self drilling hollow anchor with plenty properties is an effect way to control high stress and big deformation, which is also the direction of self drilling hollow anchor’s development.

Use of the Sinorock’s self drilling anchor System for the Stabilization of your construction.As an important form of reinforcement in geotechnical engineering, Sinorock self drilling anchor System supporting is safe, effective, and economical, etc.
