Principles of Self-Drilling Micropiles

Sinorock committed to innovating rock bolt system

Sinorock is a professional anchor bolt manufacturer, particularly in self-drilling anchor system.

Rock bolt is a contemporary basic component among mine roadway, it reinforces the roadway surrounding rock together, so the surrounding rock can support itself.

Rock bolt reinforcement can be used in any excavation geometry, is simple and quick to apply, and is relatively cheap.

Sinorock's high-quality self-drilling anchor system is supply of emergency safe-refuge system to the underground mining, tunneling, and slope industries.

As an experienced manufacturer, Sinorock provides multiple self-drilling anchoring products such as R&T thread SDA Bolt, Anti-corrosion Rock Bolt and Stainless-Steel Anchor Bolt.

Self Drilling Anchor Bolt System is a bolting solution for broken rock, loose soil and conditions which are difficult to drill holes, such as fracture zones, decayed rock.

Sinorock has been manufacturing anchor products in China for more than 10 years, we have long business relationships with famous related companies in the world.

Self-drilling anchor bolt has strong applicability, especially in the weak surrounding rock.

Self-drilling anchor bolts in hydroelectric projects can be used for supporting slope, reinforcing surrounding terrain, and avoiding hole collapse or other geological disasters.

After three years of construction, a Chinese-built toll road has opened on the island country of Jamaica.

Sinorock self-drilling anchor system performs fast and effective anchoring in all types of soil. Sinorock is an experienced manufacturer of the self-drilling anchors with more than ten years' production experience.

Sinorock is a market-leading manufacturer of anchor bolt support solutions, rock drilling tools, and custom fabricated products.

SDA bolt is often applying in the pre-support of the tunnel in metros to replace the conventional anchoring method.

Sinorock® self-drilling anchor bar can solve the hole collapse problem when drilling and ensure the grouting effect under the complicated conditions.

Sinorock® self drilling anchor bar is widely used as soil nailing wall supporting.

Sinorock® hollow anchor bolt can be used as a kind of micro piles, which can provide the lateral or vertical force.

Self-drilling hollow anchor bolts are undoubtedly a safe, effective and economical anchoring method when the tunnel is built in geological conditions with complex terrain or rockburst.
