Reinforcing the rock:Soil nail

Soil nail has the functions of convenient, reliable and economical. At the same time, during soil nailing construction, the influence for surrounding environment is little. So, soil nail supporting is widely used in foundation excavation project.
In loose soil and broken rock conditions, advance reinforcement should be carried out, such as grouting and micro pile underpinning.
Soil nail is installed in complicated geological conditions in various construction projects, such as weak surrounding rock, fault fracture zone, high geo-stress, large deformation and other common types of complex geological conditions. These conditions caused great difficulties to anchor shotcrete support construction, especially in severely hole collapse and condition required a longer soil nail, most of normal specification soil nails can not reach the capacity of anchor.
Soil nails work by reinforcing the rock – this means they improve the strength of the rock mass into which they are installed so that the rock itself becomes part of the support system. When soil nails are installed they modify the ground behaviour and can prevent or restrict
rock failure. They do this by transferring load from the unstable part of the rock mass to the soil nail itself and then into the stable ground. The strength of rod between the anchor and the rock is a measure of the effectiveness of this load transfer mechanism.
Due to the number of construction increaseing , it had a strong focus on self drilling soil nail. And this phenomenon has an impact on Sinorock,so Sinorock devoted more on the self drilling soil nails manufacturing.Sinorock has been a self drilling soil nail trusted
supplier of industrial components, parts and entire product lines.
Sinorock manufacturer self drilling soil nail system for rock reinforcement development,the Sinorock
self drilling soil nail is a dynamic bolt that yields to and withstand changing ground conditions. It is “a one-pass system, with no need for any grouting,”The Sinorock self drilling soil nail system is a permanent bolt that is less sensitive to poor ground conditions, such as weak rock mass. It
is suited for moving ground conditions as it slides at high load, maintaining high capacity support, he said.
