The foundation of the slope with Sinorock rock anchors 

Additional Details

In water conservancy projects or all kinds of underground works, such as dam, harbor, bridge base, hydropower plant, the complicated geological conditions are very common, such as soft and weak surrounding rocks and fault fracture zones, which has caused great difficulty to the construction, especially in the case of serious hole collapse. The design and application of self drilling rock anchor has greatly solved this problem.

Self drilling rock anchor can effectively improve the load capacity and ensure the overall stability of surrounding rocks when applied to broken rock, clay rock and other complex geological conditions. Based on lots of practical applications, self drilling rock anchor has been proved to achieve the ideal supporting effect and has great application value.
The foundation of the slope widening had to be comprehensively anchored in load-bearing rock. For this purpose, self drilling rock anchors were used as micropiles to stabilize the retaining structure. In this system, the tendon simultaneously serves as a drill rod as well as a micropile. This dual feature ensures a very quick installation procedure because the borehole does not have to be drilled in advance as the self drilling rock anchors are drilled and grouted simultaneously.
The Sinorock Rock Anchor System is a fully threaded steel bar which can be drilled and grouted into loose or collapsing soils without a casing. The bar features a hollow bore for simultaneous drilling and grouting and a left hand rope thread for connection to standard drill tooling. Manufactured from heavy wall steel tubing, Sinorock Rock Anchor is cold rolled to form a standard rope thread profile (R25-R51). The rolling process refines the grain structure of the steel, increasing the yield strength and producing a durable drill rod suitable for a range of applications. The standard rope thread of Sinorock Rock Anchor produces an excellent bond between the bar and grout as well as enabling connection to all conventional drill rigs and the use with a wide range of drill steel accessories and bits.
Sinorock Rock Anchor can be installed into a variety of different soils and ground conditions ranging from sand and gravel to inconsistent fill, boulders, rubble and weathered rock, as well as through footings and base slabs. Applications include: soil nails for road widening and railway embankments, ground anchors for temporary works and sheet pile tie back, mini piles for stabilisation of footings and underpinning, and roof bolts or spiles for tunnelling.
