Analysis of The Sinorock SDA bolt

In the construction where the SDA bolt is used widely, the primary problems are to improve the drilling speed and reduce the cost of engineering. Therefore, it is an relatively ideal choice to adopt the minor diameter SDA bolt and high speed drilling.
Generally speaking, if the diameter of the SDA bolt hole is ¦Õ32mm, the corresponding diameter of the SDA bolt is ¦Õ24mm. According to the construction experience, the height of the loose area in the tunnel vault is about half of the support interval. In the Japanese construction, the support interval is about 1.2~1.5m, and the height of the loose area in the tunnel vault is about 0.6~0.8m. The SDA bolt must own the ability to support the loose load of 2~3t/©O. One SDA bolt whose diameter is ¦Õ24mm can be predicted to own 20~22t ultimate supporting ability. Thus it can be seen the section design has owned enough safety.
Mine&Civil construction uses many different drilling types and methods. Shoring and anchoring, tie back walls, caissons and foundations, all require holes to be drilled. Many different types and styles of anchor bolts are also used in the construction field. For recent years we have been manufacturing anchor bolt here in the China for the construction industry. Sinorock Anchor Bolt are the cost effective solution to construction problems and have been specified by engineers for use in mining, tunneling, hydroelectric, civil construction and so on large manufacturing facilities.
Sinorock was successfully established in 2012, which since its establishment, has been successful. It has grown significantly since then with considerable future growth potential.
